Section 1: L Band VSAT Block Up Converters
1.0 Introduction
Teledyne Paradise Datacom’s second generation VSAT Block Up Converters (vBUC)
have been designed to offer the maximum utility in VSAT systems while maintaining
the highest possible reliability.
The vBUC converters are capable of using an external or optional internal 10 MHz
reference signal to phase lock the internal local oscillator. They are designed to work
over the 950 to 1825 MHz L-Band IF frequency range, and have a variety of input
power options.
A wide range of monitor and control is standard and includes
• Legacy FSK
• Standard Paradise Datacom RS485
• Ethernet interface supporting:
♦ UDP
♦ SNMP
♦ Internal Web Browser
1.1 BUC Output Power
Single-box Teledyne Paradise Datacom vBUC converters are available in the following
output power levels:
•
•
•
25W C-Band (Model Number: VBUCC25AAXXXXX)

1.2 Physical Characteristics
Teledyne Paradise Datacom has combined the robust chassis of its legacy 3100
Series VSAT BUCs with the flexibility offered by its SSPAs to produce the vBUC.
The vBUC converters are manufactured as two separate halves, the RF half and the
DC half. The RF half features a newly designed IF/Synth board which improves the
phase noise performance of the vBUC. The DC half has been redesigned to accommodate additional M&C functions including internal 1:1 redundancy and auxiliary power for an LNB or fiber-optic converter.
Figure 1-1 shows the input and output connectors of a typical Ku-Band vBUC convterter. With the exception of the RF Output, the I/O connectors are the same for all vBUC
converters regardless of the band or power level of the unit.

2.2 Power Provided through IFL Cable
If the vBUC is to be powered via the IFL cable, a Bias Tee is required to tap off the +48
VDC current and direct it to Port J7, the DC Input Connector. Some 24VDC vBUCs can
be powered via the IFL with a Bias Tee. The Bias Tee is rated for 6A and can be used
with careful design. Use Paradise Datacom Bias Tee, part number L202895-11. See
Figure 2-2.

208800 REV D
2.3 DC Cable Sizing
Depending on the actual DC load of the outdoor components on the plate assembly,
careful design consideration of the DC cable should be used.
Typical power supply cables manufactured by Teledyne Paradise Datacom use
multi-conductor cable of AWG #18. If the cable can be exposed to the environment,
the cable jacket insulation should be UV resistant.
The vBUC converters use DC/DC converters that operate as constant power devices.
Though the units operate over a wide range of input voltage, the lower the input voltage becomes, the larger the current that is drawn. This in turn causes even higher
voltage drops over the power supply cable. A good design rule is to ensure that the
vBUC has at least 40 VDC present at the plate assembly.
Thus to calculate power supply cable voltage drop use the following guideline.
AWG#18 wire resistance:
R=
6 .5Ω
= 0.0065 Ω
ft .
1000 ft
As shown in Table 2-1, the DC load of 10W Ku-Band BUC is 3.0 Amps @ 48VDC.
First consider the load power dissipated by the vBUC.
Pload = 48 v ∗ 3 . 0 Amps = 144 W
Then calculate the current drawn at 40VDC into the vBUC.
I load =
144W
= 3.6 Amps
40V
With the power supply producing 48VDC and allowing for an 8VDC voltage drop
across the cable, the maximum cable length can then be determined. See Figure 2-3.

The total cable resistance accounting for both the source and return wire is then.

Section 3: Remote Monitor and Control
3.0 Introduction
Teledyne Paradise Datacom’s Universal Monitor and Control Software is the next
generation software utility that provides M&C functionality for the Teledyne Paradise
Datacom line of Satcom Earth Station products.
All operating functions can be controlled and monitored via the M&C interface.
Functions that can be monitored include RF output power, attenuation, temperature
and internal voltages. The interface can also be used to adjust the network address,
startup state, fault handling and thresholds, as well as other parameters.
The Teledyne Paradise Datacom Universal Monitor and Control Software is included
on the CD shipped with the unit, and is also available for free download from the
Downloads page of the web site, http://www.paradisedata.com.
Section 4 details the protocol used for Serial or Ethernet communication with the
vBUC converter.
3.1 Connecting to the vBUC converter
There are a variety of methods of communicating with the vBUC converter, including
via serial communication, Ethernet or FSK.
3.1.1 Connect via Serial
A 2-wire RS485 communication connection is available on the unit’s J4 M&C port for
remote monitor and control. This is a half-duplex connection that requires the user to
tie together both the RX+/TX+ and RX-/TX- lines on the PC side of the link. A wiring
diagram is provided in Figure 3-1, with the pin-outs described in Table 3-1.

Communication links using RS485 are typically good for up to 4,000 ft., but it must be
noted that a termination resistor of 120 Ohms must be used on both ends of the link if
distances exceed 100 ft.
By default, the unit will be shipped in IPNET Mode requiring the user to use a Quick
Start Cable to force the unit into Serial Mode. A Serial Quick Start Cable, part number
L206252-2, may have been shipped with your unit. See Figure 3-2.
Figure 3-2: Cable Assembly, Serial Quick Start
The Serial Quick Start Cable can be used at any time to place the unit into a known
state under Serial Mode. Once the unit is in Serial Mode, the default baud rate will be
set to 9600. This is configurable and can be later changed using the Universal M&C
Software. Make sure the PC’s COM port is configured to 9600 baud, 8 Data bits, No
Parity, 1 Stop bit, and No Flow Control.
Install the Teledyne Paradise Datacom Universal M&C software from the supplied CD
onto a PC running Windows XP. See the Appendix for instructions for PCs running
Windows Vista.
20
208800 REV D
Terminate the RF input and output of the unit. If connected to a modem that is
equipped with FSK, ensure FSK is turned off. Connect the Quick Start Cable to Port J4
of the unit. Connect the other end of the Quick Start Cable to the PC’s RS485 port.
Configure the PC’s COM port properties as shown
below. To access the COM port properties, go to
Control Panel → System → Hardware tab →
Device Manager → Explode the Ports category →
right-click on the COM port to be configured
and select Properties. Click on Port Settings and
configure as shown in Figure 3-3. When finished,
click the OK button and close out of all windows.
Connect the DB9 connector of the serial communication cable to a computer. Install and launch the
Teledyne Paradise Datacom Universal M&C Software. Follow the instructions for connecting a vBUC
over serial communications. See Section 3.2.
Figure 3-3: COM Properties
3.1.1.1 Protocol Auto-detect
The unit serial M&C supports both Paradise vBUC Protocol (see Section 4.2) and the
Paradise Legacy protocol (also known as VSAT BUC Protocol; see the Appendix,
Drawing 201410). When communication begins, the unit will determine which protocol
is being used and will establish a link. Keep in mind that this auto-detection may result
in an initial lost packet when communication begins. Once a connection is established,
the device will continue to use the determined protocol until the power is cycled.
3.1.2 Connect via IPNET or HTTP
The Ethernet Interface provided on the J4 M&C Port allows control of the unit through
an IPNET Interface (UDP encapsulated Normal Serial Protocol - Section 4.4.1) or
HTTP Web Interface (Section 4.4.1). A wiring diagram of the required cable is shown
in Figure 3-4, with the pin-outs described in Table 3-2.

Do not untwist more cable than necessary; performance may be degraded when long lengths of cable are untwisted.
By default, the unit will be shipped in IPNET Mode. If the unit has been previously put
into Serial Mode, an Ethernet Quick Start Cable will be needed to place the unit into
IPNET Mode. An Ethernet Quick Start Cable, part number L206445-2, may have been
shipped with your unit. See Figure 3-5.
Figure 3-5: Cable Assembly, Ethernet Quick Start
Refer to the Appendix for details on the Ethernet Quick Start Cable. This cable can be
used at any time to place the unit into a known state under IPNET Mode.
Once the unit is in IPNET Mode using the Quick Start Cable, the default IP settings for
the unit will be as follows:
IP Address: 192.168.0.9
Gateway Address: 192.168.0.1
Subnet Mask: 255.255.255.0
Local Port: 1007
Web Password: paradise
These settings are configurable using the Teledyne Paradise Datacom Universal M&C
Software. But it must be noted that if the unit is powered up using the Quick Start Cable, all IP settings will be reset to the default settings.
Configure the PC’s TCP/IP properties as shown below. To access the TCP/IP properties, go to Control Panel → Network Connections → right-click on the Network Connection used for the communication (most likely “Local Area Connection”) and select
Properties. Select Internet Protocol (TCP/IP) and click the Properties button. Configure
22
208800 REV D
as seen in Figure 3-6. When finished click the OK
button and close out of all windows.
Connect the RJ45 connector of the Ethernet communications cable to the network port of a computer. Install and launch the Paradise Datacom Universal M&C Software. Follow the Universal M&C instructions for connecting a unit over Ethernet
communications. See Section 3.2.
Alternatively, the M&C can be controlled using a
web browser. To do this, configure the PC’s TCP/IP
properties as described above and connect the
RJ45 connector of the Ethernet communications
cable to the network port of a computer. Follow the Figure 3-6: TCP/IP Properties
instructions on Web-based Monitor and Control
found in Section 3.3.
3.1.3 Connect via SNMP
There are no special Quick Start Cables to enable SNMP communication with the
vBUC converter. To put the unit into SNMP Mode, first establish an Ethernet connection, using the instructions in the previous sections to do so.
Launch the Teledyne Paradise Datacom Universal M&C Software (See Section 3.2 for
details). Once connected to the device, go to the Settings tab and select “SNMP” under the Communications Interface pull-down menu. If not previously done, configure
the IP Settings under the IP Setup tab to match the network settings. After all the settings are configured, cycle the power on the unit to put the device into SNMP Mode.
Note: Make sure the Ethernet Quick Start Cable is not connected to the unit
when the power is cycled. The connection will put the unit into IPNET Mode with
the default IP settings.
Connect the RJ45 connector of the Ethernet communications cable to the network port
of a computer. Follow the instructions on SNMP operation of the unit in Section 3.4.
3.1.4 Connect via FSK
The FSK input must be diplexed onto the coaxial L-Band input via the Type N(f)
connector at J1. Communicating with the unit via FSK defaults to Paradise Datacom’s
legacy protocol. See the Appendix for the VSAT BUC Protocol (201410).
There are no special Quick Start Cables to enable FSK communication. Apply a FSK
signal to the unit and the unit will automatically switch from serial or Ethernet communication to FSK. Upon disconnect of FSK, the previous communication will resume.

3.4 SNMP Interface
SNMP-based management was initially targeted for TCP/IP routers and hosts.
However, the SNMP-based management approach is inherently generic so that it can
be used to manage many types of systems. This approach has become increasingly
popular for remote management and control solutions for various SSPA systems. The
MIB is available for download from the Downloads section of the Teledyne Paradise
Datacom web site.
3.4.1 Configuring vBUC unit to work with SNMP protocol
1. Set up the unit IP address. Use the Universal M&C to connect to the vBUC unit. Go
to “IP Setup” tab and set the following parameters.
2. Set up the unit gateway address.
3. Set up the unit subnet mask.
4. Set up the unit Community Set and Get strings.
5. Set up the unit interface to SNMP. Go to the “Settings” tab under “Communication
Interface”. Make sure the serial and Ethernet override pins are not grounded.
Restart the unit by cycling power.
6. SNMP protocol is now set and ready to be used.
3.4.2 Connecting to a MIB browser
For a MIB browser application example, we will be using the freeware browser GetIf,
version 2.3.1. There are many other browsers available for download from
http://www.snmplink.org/Tools.html.
1. Copy the provided Paradise Datacom LLC MIB file into the Getif Mibs subfolder
2. Start the GetIf application.
3. Select the unit IP address and community strings in the relevant text boxes on the
Parameters tab (see Figure 3-15) and then click the Start button.

3.5 Remote Control
3.5.1 Control Outputs - Summary Alarms
The hardware behind the form C relay is a single pole, double throw relay. Under
normal operation (no alarms) the relays are in an energized state. When a fault occurs
or the unit is powered off, the relays are in a de-energized state. The relay contacts
are capable of handling a maximum of 30 VDC @ 1A. The form C relay is shown
schematically in Figure 3-18. The form C relay contact outputs are listed in Table 1-1.

3.5.2 Control Inputs - TX Inhibit
The External Mute input is a closure to ground with pull up resistors. To trigger a
remote input command, the input should be pulled to ground. Pulling this input to
ground will disable the external mute.
3.5.3 Control Input - Serial Override
The serial override input is a closure to ground with pull up resistor. To trigger a remote
input command, the input should be pulled to ground. The input does not need to be
held to ground continuously but it is acceptable to do so. The input only need be pulled
low for a minimum of 100 msec on vBUC power-up. Pulling this input to ground will put
the vBUC into Serial RS485 Mode with a default baud rate of 9600.
3.5.4 Control Input - Ethernet Override
The Ethernet override input is a closure to ground with pull up resistor. To trigger a
remote input command, the input should be pulled to ground. The input does not need
to be held to ground continuously but it is acceptable to do so. The input only need be
pulled low for a minimum of 100 msec on unit power-up. Pulling this input to ground will
put the vBUC unit into IPNET Mode, with default parameters as shown in Section
3.2.3.
208800 REV D

3.5.5 Restore Factory Settings (Firmware ver.200 or higher)
By holding the serial override and Ethernet override to ground upon startup, the unit’s
factory settings will be restored. The inputs do not need to be held to ground continuously but it is acceptable to do so. The inputs only need be pulled low for a minimum of
100 msec on power-up.

Section 4: Remote Control Protocol
4.0 Overview
A system, which includes a vBUC converter, can be managed from a remote computer
over a variety of remote control interfaces (see Figure 4-1).

UDP
Serial Interface
Protocol:
1. Normal
RS485
Alarm Contact
vBUC unit
Figure 4-1: vBUC Remote Control Interface Stack
The M&C port on the vBUC unit provides access to a simple form of remote control.
The Serial interface supports 2-wire RS485 standards. The control protocol supports
the Normal serial protocol as detailed in Section 4.2. Serial protocol format is set at no
parity, 8 bit with 1 stop bit. Baud rate is selectable through the M&C, but defaults to
9600 baud.
The Ethernet interface provides the ability to control the system through: IPNet
interface (UDP encapsulated Normal serial protocol – Section 4.6.2); SNMP V1
(Section 4.6.3) or HTTP Web interface (Section 4.6.4). The Ethernet interface is fixed
to the 10Base-T standard. Normally, straight-through Cat5 cable is used to connect the
unit to a network hub, and crossover Cat5 is used to connect directly to a computer’s
Ethernet port.

4.1 Serial Communication Protocol
This section describes the basic serial communication protocol between the unit and a
host computer. Serial port settings must be configured for 8 bit data at no parity, with 1
stop bit.
The unit will only respond to properly formatted protocol packets. The basic
communication packet is shown in Figure 4-2. It consists of a Header, Data, and Trailer sub-packet.
HEADER
(4 bytes)
DATA
(6-32 bytes)
TRAILER
(1 byte)
Figure 4-2: Basic Communication Packet
4.2.1 Header Packet
The Header packet is divided into three sub-packets which are the Frame Sync,
Destination Address, and Source Address packets, as shown in Figure 4-3.

(6-32 bytes)
Frame Sync (2 bytes)

Figure 4-3: Header Sub-Packet
4.2.1.1 Frame Sync Word
The Frame Sync word is a two byte field that marks the beginning of a packet. This
value is always 0xAA55. This field provides a means of designating a specific packet
from others that may exist on the same network. It also provides a mechanism for a
node to synchronize to a known point of transmission.
4.2.1.2 Destination Address
The destination address field specifies the node for which the packet is intended. It
may be an individual or broadcast address. The broadcast address is 0xAA. This is
used when a packet of information is intended for several nodes on the network. The
broadcast address can be used in a single device connection when the host needs to
determine the address of the unit. The unit will reply with its unique address.
38
208800 REV D
4.2.1.3 Source Address
The source address specifies the address of the node that is sending the packet. All
unique addresses, except the broadcast address, are equal and can be assigned to
individual units. The host computer must also have a unique network address.
4.2.2 Data Packet
The data sub-packet is comprised of six to 32 bytes of information. It is further divided
into seven fields as shown in Figure 4-4. The first 6 fields comprise the command preamble while the last field is the actual data.

4.2.2.1 Protocol ID
This field provides backward compatibility with older generation equipment protocol. It
should normally be set to zero. This field allows the unit to auto-detect other firmware
versions.
4.2.2.2 Request ID
This is an application specific field. The unit will echo this byte back in the response
frame without change. This byte serves as a request tracking feature.
4.2.2.3 Command
The vBUC protocol is a table based protocol. It allows the user to view and modify data
tables located on the controlled device. Throughout the remainder of this description,
“sender” will refer to the host PC, and “receiver” will refer to the unit.
Sender and receiver are limited to two commands and two command responses. The
Get Request command issued by a command sender allows monitoring of existing
conditions and parameters on the receiver. The Get Request frame should not have
any bytes in the Data Filed and be no longer than 11 bytes.
208800 REV D
39
The Response frame from the receiver will contain a Get Response designator in the
Command field. If the receiver does not detect any errors in the Get Request frame,
the requested data will be attached to the response frame. The length of the Get
Response frame varies by the amount of attached data bytes. It may contain 11+N
bytes where N is the amount of requested data bytes from a particular table, specified
in the Data Length field.
The Set Request command allows the sender to actively change parameters for the
receiver’s internal configuration. The Set Request frame must contain a number of
bytes in the Data Field as specified in the Data length field. The frame size must be
11+N bytes, where N is the length of the attached data structure. The receiver will
respond with a frame where the command field will be set to a Set Response
designator. The frame length is equal to the Request frame.
The byte value for each command is given in Table 4-1.

The data tag specifies the type of internal resource or information needed to be
accessed on the unit. The data associated with certain tags is read only. Therefore
only the “Get” command byte would be associated with these data tags. The data tag
byte values are given in Table 4-2.

4.2.2.5 Error Status / Data Address
This byte is a tag extension byte and specifies the first data element of the tagged data. If the Data Length is more then 1 byte, then all subsequent data fields must be accessed starting from the specified address. For example if the requestor wants to access the unit’s unique network address, it should set data tag 0 (System settings tag)
and data address 8 (see System Settings Details table). If the following Data Length
field is more than 1, then all subsequent Settings will be accessed after the Unique
Network Address. When the Response Frame Data Address is omitted, this byte position is replaced with the Error Status fields. The various error codes are given in Table
4-3. Note that the Request and Response frames are different.

4.2.2.6 Data Length
This byte contains different information for Request and Response frames. In a Request frame, it specifies the number of data bytes that are to be accessed starting from
the first byte of the value specified in the Data Address byte. That byte must not exceed the maximum data bytes for a particular tag. The maximum data length for the
Settings tag is 26 bytes. The maximum data length for the System Threshold tag is 6
bytes.
4.2.2.7 Data Field
The actual data contained in the packet must be placed in this field. The “Get Request” type of command must not contain any Data Field. Any “Get Request” will be
rejected if any data is present in the Data Field. Generally, the Bad Checksum error
code will be added to the response from the unit if the word size of the information is
16-bits or 2-bytes. Each data word is placed in the frame with its least significant byte
first. All data with length of 2 bytes must be represented as integer type with maximum
value range from 32767 to (-32767).

Figure 4-5: Trailer Sub-Packet
This field provides a checksum during packet transmission. This value is computed as
a function of the content of the destination address, source address and all Command
Data Substructure bytes. In general, the sender formats a message frame , calculates
the check sequence, appends it to the frame, then transmits the packet. Upon receipt,
the destination node recalculates the check sequence and compares it to the check
sequence embedded in the frame. If the check sequences are the same, the data was
transmitted without error. Otherwise an error has occurred and some form of recovery
should take place. In this case the unit will return a packet with the “Bad Checksum”
error code set. Checksums are generated by summing the value of each byte in the
packet while ignoring any carry bits. A simple algorithm is given as:
Chksum=0
FOR byte_index=0 TO byte_index=packet_len-1
Chksum=(chksum+BYTE[byte_index]) MOD 256
NEXT byte_index
4.3 Timing issues
There is no maximum specification on the inter-character spacing in messages. Bytes
in messages to units may be spaced as far apart as you wish. The unit will respond as
soon as it has collected enough bytes to determine the message. Generally, there will
be no spacing between characters in replies generated by units. The maximum length
of the packet sent to the unit node should not exceed 64 bytes, including checksum
and frame sync bytes. Inter-message spacing, must be provided for good data transmission. The minimum spacing should be 100 ms. This time is required for the controller to detect a “Line Cleared” condition with half duplex communications. Maximum
controller respond time is 200 ms.

4.4 Ethernet Interface
The vBUC converter supports several IP network protocols to provide a full featured
remote M&C interface over an Ethernet LAN.
•
•
IPNet protocol – redirection of standard Teledyne Paradise Datacom LLC
serial protocol over UDP transport layer protocol. This protocol is fully supported in Teledyne Paradise Datacom’s Universal M&C software.
SNMPv1 protocol - protocol intended for integration into large corporate
NMS architectures.
In order to utilize either of the protocols listed above, the relevant interface option has
to be turned on. Refer to Section 4.4.1.2 (Setting IPNet interface) and Section 4.4.2.4
(Configuring unit to work with SNMP protocol) for details.
Of course, standard IP level functions such as ICMP Ping and ARP are supported as
well. There is currently no support for dynamic IP settings, all IP parameters.
4.4.1 IPNet Interface
4.4.1.1 General Concept
Satcom system integrators are recognizing the benefits of an Ethernet IP interface.
These benefits include:
•
•
•
•
Unsurpassed system integration capabilities;
Widely available and inexpensive set of support equipment (network cable;
network hubs);
Ability to control equipment over Internet;
Ease of use
Implementation of the raw Ethernet interface is not practical due to the limitations it
places on M&C capabilities by the range of a particular LAN. It is more practical to use
an Ethernet interface in conjunction with the standard OSI (Open System Interconnect)
model to carry a stack of other protocols. In an OSI layered stack, an Ethernet
interface can be represented as a Data Link layer. All upper layers are resolved
through a set of IP protocols. In order to keep data bandwidth as low as possible
(which is important when M&C functions are provided through a low-bandwidth service
channel) the IP/UDP protocol set is used as the Network/Transport layer protocol on
Teledyne Paradise Datacom units.
UDP (User Datagram Protocol) was chosen over TCP (Transmission Control Protocol)
because it is connectionless; that is, no end-to-end connection is made between the
unit and controlling workstation when datagrams (packets) are exchanged.
208800 REV D
49
Teledyne Paradise Datacom provides a WindowsTM-based control application to
establish UDP-based Ethernet communication with units. The control application
manages the exchange of datagrams to ensure error-free communication. An attractive
benefit of UDP is that it requires low overhead resulting in minimal impact to network
performance. The control application sends a UDP request to the unit and waits for response. The length of time the control application waits depends on how it is configured. If the timeout is reached and the control application has not heard back from the
agent, it assumes the packet was lost and retransmits the request. The number of the
retransmissions is user configurable.
The Teledyne Paradise Datacom Ethernet IP interface can use UDP ports from 0 to
65553 for sending and receiving. The receiving port needs to be specified through the
front panel menu. For sending, it will use the port from which the UDP request originated. Of course, it is up to the user to select an appropriate pair of ports that are not conflicting with standard IP services. Teledyne Paradise Datacom recommends usage of
ports 1038 and 1039. These ports are still not assigned to any known application.
As an application layer protocol (which actually carries meaningful data), the standard
Paradise Datacom serial protocol was selected. This protocol proves to be extremely
flexible and efficient. It is also media independent and can be easily wrapped into
another protocol data frame. An example of the UDP frame with encapsulated
Teledyne Paradise Datacom protocol frame is shown on Figure 4-6.

This set of Ethernet IP protocols is currently supported by Teledyne Paradise Datacom
Universal M&C package. The software package can be download from company's web
site, http://www.paradisedata.com.
4.4.2 SNMPv1
A vBUC unit supports the most popular SNMPv1 format (SMIv1, RFC1155), SNMP
Get, SNMP Get Next and SNMP Set commands. SNMP Traps are currently unsupported.
In order to utilize SNMP protocol, the user has to enable this feature via remote serial
protocol. SNMP uses the UDP fixed port 161 for sending and receiving requests.
The definition of managed objects is described in the Teledyne Paradise Datacom
MIB. The MIB file is available for download from the Downloads section of the
company web site, http://www.paradisedata.com.

Section 5: Redundant Operation
5.0 Redundant System Concepts
The vBUC converter is capable of operating in a variety of redundant system
configurations, including 1:1 with input splitting, 1:1 with input switching, 1:2 with the
addition of a reference combiner assembly, or as part of a 1:1 transceiver system. The
vBUC converter has a built-in 1:1 redundancy controller, allowing it to be used in 1:1
redundant transmit systems without a separate external controller. When used in a 1:2
redundant system, a separate controller, the RCP2-1200, is required. When used in a
transceiver system, a RCPD-1100-LX controller is needed.
The two most common forms of 1:1 redundant system are shown in Figure 5-1 and
Figure 5-2. Figure 5-1 shows a standard 1:1 system in which the L-Band input is
transmitted through a transfer switch along with the output. Using this configuration the
standby unit carries no traffic and simply is terminated by a 50 ohm resistive load at its
input and by a waveguide termination at its output.

Figure 5-1: Standard 1:1 Redundant System with input (coaxial) switch and
output (waveguide) switch
With the system configured as in Figure 7-2, the L-Band input is passed through a
microwave splitter. Care must be taken when selecting the splitter for an L-Band input
system. The splitter must be a wide band design capable of passing the 10 MHz or 50
MHz reference signal along with the 950 MHz to 1825 MHz traffic input. The reference
frequency power level must be at least -10 dBm into each unit.

5.1 vBUC in 1:1 Redundancy
The vBUC converter is ideally suited for a self-contained and cost effective 1:1
redundant system. Each unit has a built-in 1:1 redundant controller. The controller is
activated via computer command from the Teledyne Paradise Datacom Universal M&C
application. The unit may be purchased as a redundant system or upgraded in the field
from a single thread unit to a 1:1 redundant system.
5.1.1 Hardware Setup
The hardware setup for a 1:1 Redundant System is very simple and involves the
addition of a single cable along with a redundancy switch. A schematic diagram of the
redundancy setup is shown in Figure 5-3.

Figure 5-3: 1:1 Redundant System with 1:1 Cable Installed
The Link section of the cable is a simple (3) conductor crossover cable that allows the
system to pass command and control between units.
The Switch section of the cable is a “Tee” configuration and connects between each
unit and the redundancy switch. The Redundancy Switch is a -48 VDC type or a -24
VDC if using 24V input voltage. Therefore the controller in each vBUC converter is
capable of supplying +48 VDC to the common voltage input. Either controller may then
provide a (sink) return to engage either position 1 or position 2 of the redundancy
switch.
Care must be observed when connecting this cable to the units. The cable end labeled
“A1” must be connected to the unit whose output is connected to Port 3 of the
waveguide switch. Likewise the cable end labeled “A2” must be connected to the unit
whose output is connected to Port 1 of the waveguide switch. This is for proper
identification purposes of the Redundancy Control Firmware used by each unit.

5.1.2 Software Setup
To instruct the unit to operate in redundancy it is necessary to temporarily connect it to
a PC running the Teledyne Paradise Datacom Monitor and Control Software to set up
the redundant configuration. There are three basic modes of Redundant System
communication.
1. Stand-Alone 1:1 Redundant System - No Computer Control
2. PC Control using RS485 and Paradise M&C Software
3. PC Control using Ethernet and Paradise M&C Software
5.1.2.1 Stand-Alone 1:1 Redundant System
As method 1 implies, it is possible to have a 1:1 system operate with no PC monitor
and control. Initially, however, it is necessary to connect each unit to a PC to configure
it for redundant operation. Figure 5-4 shows the redundant system with each unit
enabled to use Ethernet communication to a PC. Every vBUC converter is shipped
from the factory with a “Quick Start” cable that can be used for this purpose. If the
vBUCs are purchased as a 1:1 Redundant System, this Software Setup procedure will
have been set at the factory and it is not necessary to repeat this process.

Each unit can be configured for redundancy by the Teledyne Paradise Datacom
Universal M&C software that ships with each unit. Using the Quick-Start cable, connect
each unit individually to the PC and run the M&C program. Select the “Settings” tab
from the main form. The “Settings” window will appear as shown in Figure 5-5.
Figure 5-5: Universal M&C Settings Window
1. Operation Mode: Each unit’s Operation Mode must be set to “1:1 Redundant
Mode”
2. Choose a Hierarchical Address for each unit. Unit 1 means this unit will use
the switch position 1 as its On Line state position. Unit 2 will then use switch
position 2.
3. Redundant Startup State: The unit which is desired to be on line should be
set “On Line”. The other unit should be set as “Standby”.
All settings are valid as soon as
the operator sets them on the
Settings window. The unit’s
redundant operation can be
verified by monitoring the RF
Switch Fault indicator on the
Status window as shown in
Figure 5-6.
Figure 5-6: RF Switch Fault Indicator

208800 REV D
The Standby unit can set to a “Cold Standby” condition. In this mode, the unit will be
muted automatically. Cold standby mode has to be selected through a serial control
interface (For details, see Table 4-11, data address 20).
If the Standby unit is switched to the On Line state, it will automatically un-mute and
transmit traffic. If the operator attempts to mute the On Line unit, a warning message
will be displayed “You are about to mute the On Line unit. Proceed with Mute?”
Similarly, connect the second unit to the computer and perform the 1:1 selections on
the Settings window. Just as with the first unit, make sure that the System mode is set
to 1:1 redundant. Select a hierarchical address, Unit 1 or Unit 2 and a startup state.
The converters may then be disconnected from the computer as the units’
microcontrollers are now programmed for 1:1 redundancy control. It is not necessary to
run the Windows based M&C software with the redundant system. The M&C software
is only a convenience for remote monitoring and control of the redundant system.
The following sections detail the operation of the M&C software in 1:1 redundant
system operation.
5.1.2.2 PC Control using RS485 and Paradise M&C Software
In applications requiring remote monitor and control of the redundant system, the
Teledyne Paradise Datacom Universal M&C program has a control panel that can be
used for this purpose. To enable the 1:1 system to operate with the remote control
software, first configure each unit for 1:1 redundant operation as previously described
in the Stand-Alone 1:1 Redundant System section.
The RS485 link can typically be run up to 4000 ft. (1200 m) lengths. A good quality
twisted pair cable should be used along with proper line terminations. There are no
parallel end terminations in the unit’s RS-485 interface. Any required cable
terminations have to be added externally. Only half duplex RS-485 communication is
supported.
As in the stand-alone redundant system of Section 5.1.2.1, each unit must be
programmed for Redundant System operation by using the M&C program. Additionally,
when networking, each unit’s address must be set before they can communicate on
the RS-485 network. Both of these steps should be performed together as part of the
initial system setup. To specify an address for an unit refer to the “Settings” window. If
the unit already has a network address it will be displayed under the current address
window. Repeat this step for both units and they will be ready to operate as a 1:1
Redundant System with RS-485 network monitor and control.
208800 REV D

After starting the M&C program, select “Action” → “Add
Unit” → “vBUC”. The Add New vBUC window will appear
as shown in Figure 5-7.
From this screen choose the COM port and baud rate.
The factory default baud rate is 9600. Select the first unit
address.
After the COM port has been selected the “Operation”
window will be displayed. At this point if the SSPA is
connected to a power source and turned on, the vBUC will
begin communicating with the M&C program and its
operating parameters will be displayed.
Go back to the “Add New vBUC” window and select the
Figure 5-7: Add vBUC
correct address for the second unit. Its operation window
will appear on the M&C program display. If either of the units is not communicating with
the M&C Operation screen, debug the system to find the problem. Check the RS-485
connection from each amplifier to the appropriate COM port of the PC.
Once reliable communication has been established between each unit and the
computer, the Redundancy Control Panel can be displayed. From the M&C program’s
main window, choose “Action” → “Add Unit” → “Internal Redundant System” → “1:1
vBUC System”.
The Redundant Control Panel window will then be displayed as in Figure 5-8.
Figure 5-8: Redundant Control Panel Window
64
208800 REV D
Note that once the Redundant Control Panel is enabled, the Main Menu on the M&C
program changes.
The Control Panel must be configured by selecting “Set Redundancy System” and
assigning Unit 1 and Unit 2. Either unit may be designated as Unit 1 or Unit 2. Each
unit is identified by its ID number. The ID number is a fixed number and cannot be
changed. It is a unique encoded value determined by the particular unit’s model
number and serial number. If the ID number is forgotten, refer to the System Watcher
window. This window continuously displays which unit, by ID number, is connected to
each specific COM port.
From the Control Panel display all typical 1:1 system functions can be monitored and
controlled. A particular unit can be put on line be selecting the command button for
either unit. The online unit will be indicated by the “Online” notation. The standby unit
will be listed as such as shown in Figure 5-8 (Unit 1).
A particular redundant configuration can be saved by going to the “File” menu and
selecting “Save Configuration”. Thus if the program is terminated and then restarted, it
will immediately boot up with the Redundancy Control Panel display.
Each individual unit’s characteristics can still be monitored and controlled from its
respective “Operation” window. If the user attempts to Mute an on-line unit, a warning
window will pop-up asking if this is a valid request.
5.2 1:2 Redundant Systems
The vBUC converter can also be configured in 1:2 Redundant Systems. The major
difference being that the converter’s internal controller can not be used for system
control. Instead a separate RCP2-1200 Redundant System controller is used to
provide system control. The controller can be remotely located from the converters up
to 500 ft. Figure 5-9 shows a block diagram of a 1:2 Redundant System.

5.3 1:2 Redundant Systems with L Band Input
The 1:2 Redundant System with L Band Input can be configured with internal 10 MHz
reference oscillators or configured for use with an external reference source. Systems
configured with internal 10 MHz reference are straightforward extensions of the basic
1:2 architecture. Because the 10 MHz reference is integral to the converter there is no
possibility of an interruption of the 10 MHz during switchover. Furthermore the standby
unit always has 10 MHz reference and will not be faulted. Such a system is shown in
Figure 5-10.

A special case of the 1:2 Redundant System exists when an external reference is
required of the system. With an external 10 MHz reference input on each polarity input
to the system, the standby unit will not receive a reference signal and therefore would
be in a faulted condition. In this state, the redundant controller will not allow the
standby unit to come on line if a failure occurs with Unit 1 or Unit 3. See Figure 5-11.

Figure 5-12: Block Diagram, Switchover Interrupts 10 MHz Signal
At first it may be thought that an external reference signal could be injected into the
normally terminated port of the input switches. While in a normal operating state with
all three units operational this would work fine. However in the event of a failure of one
of the on-line units, the external reference would also be interrupted to the standby
unit, as shown in Figure 5-12. Due to the quick determination of a unit fault, the
controller will interpret a fault on the standby unit and reliable switchover can not be
guaranteed.
To overcome the problems that result from interruption of the external reference, it is
imperative that the reference be injected in the system after the waveguide switches.
One technique could be to install a multiplexer on the input of each unit that would
allow the injection of the external reference. In this case a separate external reference
line would have to be run to the system and a three way splitter could distribute the
reference to each amplifier.
The standard Teledyne Paradise Datacom configuration overcomes this issue by using
a Reference Combiner assembly. See Figure 5-13.
The Reference Combiner assembly couples a sample of the external reference from
each of the two polarity inputs. It will then supply the standby unit with the reference
from either of the two inputs. The reference combiner will arbitrate and decide which
reference signal to supply to the standby unit. It will not supply both external reference
sources to the standby unit. This allows all three units to be in a normal operating (non
faulted) condition and the RCP2-1200 controller can operate the system in normal 1:2
redundancy. This eliminates the need for a separate external reference going to the
system as the external reference normally exists on each L-Band cable.

Unit 2 is meant to be the standard stand-by unit in this configuration. Should Unit 1 or
Unit 3 fault, the RCP2-1200 will automatically switch to the stand-by Unit 2. However,
when this occurs, this interrupts the external reference to the faulted unit, which results
in a constant BUC fault on that thread. In order to return Unit 2 to the stand-by state,
the user will need to clear the fault, switch to manual mode on the RCP2-1200 and
then select Unit 2 as stand-by. Table 5-1 gives a step-by-step guide to returning Unit 2
to stand-by status.

5.4 1:1 Redundant Transceiver System
Teledyne Paradise Datacom can configure a complete transceiver system utilizing a
vBUC converter redundant system, an LNB redundant system and a RCPD-1100-LXEXT system controller.
Figure 5-14 shows a typical block diagram of a transceiver system.
Figure 5-14: Block Diagram, 1:1 Redundant Transceiver System with RCPD-1100
5.4.1 Hardware Setup
RCPD-1100-LX-EXT Dual Redundant Controller is an indoor rack-mountable unit that
fits into a standard EIA 19 inch equipment rack.
The RCPD-1100 is used to control the RF switches for both the vBUC plate assembly
and the LNB plate assembly of the transceiver system, so a single RF thread is always
active. Teledyne Paradise Datacom supplies the Switch/BUC Alarm cable, which links
between the controller and the vBUC plate assembly, and the LNB switch cable, which
links between the vBUC plate assembly and the LNB plate assembly. The customer
must supply the TX and RX IFL cables that link the indoor and outdoor equipment.
The RCPD-1100 acts as a hub between the indoor and the outdoor components of the
VSAT Transceiver System. The RCPD-1100 monitors the alarms from the Block Up
Converter plate assembly and the Low Noise Block Down Converter plate assembly
and controls the RX/TX switches for each sub-system.
208800 REV D
69
A external 10 MHz reference signal is passed through the controller an on to the BUC
Plate Assembly and LNB Plate Assembly.
The controller is fitted with an RF switch in the receive path, which terminates the
receive signal of the standby LNB, thus avoiding adding any additional noise to the RX
signal path. By definition of Dual Redundancy using an RCPD-1100 controller, the RX
and TX switches are essentially “ganged” and move together.
For independent switching of the RX and TX switches, the system should be configured with two (2) RCP2-1100 controllers.
The redundant vBUC plate comes fully assembled and consists of two transmit chains,
an RF switch, an RF load and all of the interconnect waveguide assemblies with a
waveguide output flange to meet your specific frequency band. The vBUC’s operating
functions such as Phase Lock, RF output power, attenuation, temperature and internal
voltages are controlled and monitored by the RCPD-1100 via the M&C interface.
The redundant LNB assembly comes fully assembled and consists of two LNBs, an RF
switch, a close out plate, and interconnecting waveguide assemblies to meet your
specific frequency band. The LNBs are powered via the controller at +15VDC, and the
frequency stability is maintained by either an internal reference or externally via the
controller.
For full, automatic redundancy switching, Teledyne Paradise Datacom modifies the
OEM LNBs to add fault detection alarm circuitry that is monitored by the RCPD-1100
and reports a fault based on changes in the modified LNB’s bias current.
Table 5-2 shows the typical OEM LNBs and their performance specifications.

6.2 IFL Cable Design
Consideration should be given to using a high quality IFL between the indoor and
outdoor equipment. The system designer must always consider the total cable loss for
a given length and also the implications of the slope of attenuation across the following
bandwidths, depending on the vBUC frequency:
Standard C-Band
Extended C-Band
Extended C-Band 2
Standard X-Band
Standard Ku-Band
Extended Ku-Band
950 - 1525 MHz
950 - 1825 MHz
950 - 1675 MHz
950 - 1450 MHz
950 - 1450 MHz
950 - 1700 MHz
Table 6-4 gives the approximate attenuation vs. frequency for a variety of cable types.
It is recommended to use a quality grade of 50 ohm cable such as Belden 9913, 9914,
or 7733. Check the manufacturer’s technical data to make sure that the insulation is
sufficient for the particular installation including the cable’s temperature range. Also
make sure that the coaxial connector from the IFL cable to the unit input is wrapped
with a weather sealing tape to prevent water intrusion into the coaxial cable.

Appendix B: Proper 10/100 Base-T
Ethernet Cable Wiring
This section briefly describes the basic theory related to the physical layer of
10/100Bas-T networking, as well as proper wiring techniques.
There are several classifications of cable used for twisted-pair networks. Recommended cable for all new installations is Category 5 (or CAT 5). CAT 5 cable has four twisted pairs of wire for a total of eight individually insulated wires. Each pair is color coded
with one wire having a solid color (blue, orange, green, or brown) twisted around a
second wire with a white background and a stripe of the same color. The solid colors
may have a white stripe in some cables. Cable colors are commonly described using
the background color followed by the color of the stripe; e.g., white-orange is a cable
with a white background and an orange stripe.
The straight through and crossover patch cables are terminated with CAT 5 RJ-45
modular plugs. RJ-45 plugs are similar to those you'll see on the end of your telephone cable except they have eight versus four or six contacts on the end of the plug
and they are about twice as big. Make sure they are rated for CAT 5 wiring. (RJ
means "Registered Jack"). A special Modular Plug Crimping Tool (such as that shown
in Figure B-1) is needed for proper wiring.
Figure B-1: Modular Plug Crimping Tool
The 10BASE-T and 100BASE-TX Ethernets consist of two transmission lines. Each
transmission line is a pair of twisted wires. One pair receives data signals and the other pair transmits data signals. A balanced line driver or transmitter is at one end of one
of these lines and a line receiver is at the other end. A simplified schematic for one of
these lines and its transmitter and receiver is shown in Figure B-2.
Figure B-2: Transmission Line
208800 REV D
87
The main concern is the transient magnetic fields which surrounds the wires and the
magnetic fields generated externally by the other transmission lines in the cable, other
network cables, electric motors, fluorescent lights, telephone and electric lines, lightning, etc. This is known as noise. Magnetic fields induce their own pulses in a transmission line, which may literally bury the Ethernet pulses.
The twisted-pair Ethernet employs two principle means for combating noise. The first is
the use of balanced transmitters and receivers. A signal pulse actually consists of two
simultaneous pulses relative to ground: a negative pulse on one line and a positive
pulse on the other. The receiver detects the total difference between these two pulses.
Since a pulse of noise (shown in red in the diagram) usually produces pulses of the
same polarity on both lines one pulse is essentially canceled by out the other at the
receiver. In addition, the magnetic field surrounding one wire from a signal pulse is a
mirror of the one on the other wire. At a very short distance from the two wires, the
magnetic fields are opposite and have a tendency to cancel the effect of each other.
This reduces the line's impact on the other pair of wires and the rest of the world.
The second and the primary means of reducing cross-talk between the pairs in the cable, is the double helix configuration produced by twisting the wires together. This configuration produces symmetrical (identical) noise signals in each wire. Ideally, their difference, as detected at the receiver, is zero. In actuality, it is much reduced.
Pin-out diagrams of the two types of UTP Ethernet cables are shown in Figure B-3.
Figure B-3: Ethernet Cable Pin-Outs
Note that the TX (transmitter) pins are connected to corresponding RX (receiver) pins,
plus to plus and minus to minus. Use a crossover cable to connect units with identical
interfaces. If you use a straight-through cable, one of the two units must, in effect, perform the crossover function.
Two wire color-code standards apply: EIA/TIA 568A and EIA/TIA 568B. The codes are
commonly depicted with RJ-45 jacks as shown in Figure B-4. If we apply the 568A color code and show all eight wires, our pin-out looks like Figure B-5.
Note that pins 4, 5, 7, and 8 and the blue and brown pairs are not used in either standard. Quite contrary to what you may read elsewhere, these pins and wires are not
used or required to implement 100BASE-TX duplexing.

There are only two unique cable ends in the preceding diagrams, they correspond to
the 568A and 568B RJ-45 jacks and are shown in Figure B-6.

Again, the wires with colored backgrounds may have white stripes and may be
denoted that way in diagrams found elsewhere. For example, the green wire may be
labeled Green-White. The background color is always specified first.
Now, all you need to remember, to properly configure the cables, are the diagrams for
the two cable ends and the following rules:
•
•
A straight-thru cable has identical ends.
A crossover cable has different ends.
It makes no functional difference which standard you use for a straight-thru cable.
You can start a crossover cable with either standard as long as the other end is the
other standard. It makes no functional difference which end is which. 568A patch
cable will work in a network with 568B wiring and 568B patch cable will work in a 568A
network
Here are some essential cabling rules:
1. Try to avoid running cables parallel to power cables.
2. Do not bend cables to less than four times the diameter of the cable.
3. If you bundle a group of cables together with cable ties (zip ties), do not overcinch them. It's okay to snug them together firmly; but don't tighten them so
much that you deform the cables.
4. Keep cables away from devices which can introduce noise into them. Here's
a short list: copy machines, electric heaters, speakers, printers, TV sets,
fluorescent lights, copiers, welding machines, microwave ovens, telephones, fans,
elevators, motors, electric ovens, dryers, washing machines, and shop equipment.
5. Avoid stretching UTP cables (tension when pulling cables should not exceed
25 LBS).
6. Do not run UTP cable outside of a building. It presents a very dangerous
lightning hazard!
7. Do not use a stapler to secure UTP cables. Use telephone wire/RG-6
coaxial wire hangers, which are available at most hardware stores.
