Overview
The PK-232SC is the latest generation of multimode data controllers built upon the solid
foundation of the legendary PK-232. The PK-232SC features an expanded interface to
connect and control your radio transceiver, station accessories and computer.
The key to the new PK-232SC is a single USB cable from your PK-232SC to your
computer. No other connection is necessary. Note the PK-232SC block diagram in
Figure 1. The USB cable from the computer connects to a four port USB hub inside the
PK-232.
Port 1 of the USB hub connects to a dual USB-to-UART bridge.
One of the UART serial ports connects directly to the PK-232SC UART serial port. This
shows up on your computer as a standard COM port. Your software terminal program
connects to this COM port to control the PK-232SC.
The other UART serial port is the rig control port. This optically isolated port supports
Icom CI-V, Yaesu CAT, Kenwood logic level, and RS-232 connections. This shows up
on your computer as an enhanced COM port. Your software rig control program controls
your transceiver.
Port 2 of the USB hub connects to a USB Audio sound card inside the PK-232SC.
The sound card audio is transformer isolated from the USB circuitry. The sound
card/PK-232 switch or a software command selects either sound card transmit audio or
PK-232SC transmit audio. Receive audio from your transceiver is always connected to
both the sound card receive audio and the PK-232 receive audio.
Ports 3 and 4 of the USB hub connect to a dual USB jack on the back panel of the
PK-232SC. Use these jacks for rig control of USB-equipped transceivers and for other
USB station accessories.
A new feature in the PK-232SC is an instant reset switch. A quick flick of the switch
when the power is off resets the PK-232SC to factory default condition.

Operation
Note: This manual covers the features added with the SC version of the PK-232.
The main PK-232 manual describes the modes and features found in the
original PK-232 and PK-232MBX. The DSP manual supplement describes
the DSP board features.
PC USB Connection
Connect the PK-232SC to an USB 2.0 compatible port on a computer with a single USB cable (USB miniB
to USB A). No other computer connections are required. The computer USB port must be capable of
supplying full USB power (5.0 Volts @ 500mA.) If a USB hub is used, it must be a powered hub.
USB device driver
The device drivers for Windows XP/VISTA/7 will load automatically when the PK-232SC is connected to
your Windows PC if it is connected to the internet. The drivers are also found on the CD distributed with
the PK-232SC and on the Timewave web site (www.timewave.com.) Other drivers are available for Linux
and Apple computers. Please contact Timewave or visit the Timewave website for further information.
Note: This device driver is different from previous PK-232/USB device drivers. The older drivers will not
work for the PK-232SC.
Power
Connect the PK-232SC to a +13VDC @ 750 mA. power supply. Press the PK-232SC power switch to the
IN position. This connection is the same for all models of the PK-232.
Radio
Connect your radio data audio input, data audio output and PTT line to the PK-232SC Radio 1 or Radio 2
ports. This connection is the same for all models of the PK-232. If you are upgrading your PK-232MBX
to a PK-232SC, you can use your existing cable if you do not change radios. This connection is the same
for all models of the PK-232.
PK-232SC Ports
The PK-232Sc has two COM ports, a USB Audio sound card port and 2 USB ports.

The PK-232 terminal program uses the “standard” COM port to control the PK-232SC operation.

The PK-232SC rig control program uses the “enhanced” COM port to control your transceiver.

The PK-232SC sound card mode programs use the “USB Audio Codec” to run sound card
programs.

The PK-232SC USB ports appear on your computer USB port list and can be used for USB 2.0
compatible USB devices.
12
Some programs will automatically identify the correct ports for their functions. Others may have limited
ability to aid you in connecting the correct port to your software application. If you wish to identify or edit
the various PK-232SC ports, use the Device Manager application found in Windows XP/VISTA/Win7. Go
to Control Panel/System or Computer/properties to find Device Manager. You should learn to use Device
Manager to help you understand and manage the hardware configuration of your PC for all your devices
and programs.
PK-232SC Control
The PK-232 terminal program uses the “standard” COM port to control the PK-232SC operation. You
can use a variety of programs to control the PK-232SC A “dumb” terminal program such as
Hyperterminal (Windows XP) or puTTY allows you to control the PK-232SC in command mode. There
is little or no automation so all commands must be entered manually. Some programs have macros that let
you create commands by stringing together a series of commands that can be sent with one or two
keystrokes.
Other programs offer complete control of the PK-232SC with standard Windows graphical commands,
mouse actions and keystrokes. If you need a program with complete PK-232SC support, Timewave
recommends Radio Operating Center (ROC) from W4PC Software, Inc. (www.w4pcsoftware.com).
We suggest you contact the author of your favorite program to determine its level of PK-232SC support.
Timewave has a free applet called “ModemSwitch” (www.timewave.com.download.html that will switch
the PK-232 from transmit to receive and from sound card to PK-232 mode. It also has a simple dumb
terminal program for testing the PK-232.
Rig Control
Connect your radio rig control port to the matching PK-232SC CAT/CIV, 8 pin miniDIN, or RS-232
connector. Only one of the three connectors may be connected at one time. You may also connect one of
the two USB connectors to your radio if it supports USB rig control. Rig control is a connection for the
PK-232SC only. Earlier models of the PK-232 do not have this connection.
Timewave has several standard rig control cables for popular models of radios. We can supply a cable for
any compatible radio. Please contact us for details.
Your rig control software and your radio determine your rig control operating features. The PK-232SC rig
control circuitry is an interface only and does not affect the actual rig control operation.
Timewave recommends Radio Operating Center (ROC) from W4PC Software, Inc.
(www.w4pcsoftware.com) and Ham Radio Deluxe (www.ham-radio-deluxe.com) for rig control.
The PK-232SC operating COM port and the PK-232SC rig control COM port are independent.
You can use different PK-232SC operating and rig control programs simultaneously. For example, you
may use Ham Radio Deluxe for rig control and ROC for operating a PK-232SC mode such as Pactor.
USB Audio Sound Card
The USB audio sound card built into the PK-232SC appears as a separate audio device on your PC. It is
called “USB Audio Codec”. No software driver is necessary when you use the USB Audio Codec. You
must select the USB Audio Codec when you configure your terminal program to operate sound card modes
such as PSK-31. Use the program settings window in Radio Operating Center or the soundcard settings in
Digital Master 780 found in Ham Radio Deluxe.
13
SC Board Jumper Settings
The SC board has several jumper options that may be changed by the user. In most instances the jumpers
can be left at the factory default settings. The jumpers are located on the SC daughter board at the rear of
the PK-SC.
Rig Control
Not all transceivers have the same polarity settings for their logic level rig control ports. The PK-232SC
polarity settings for RX, TX, RTS and CTS can be changed to meet the requirements of any specific
transceiver. The factory default settings for JP1 (RX), JP2 (TX), JP3(RTS) and JP4(CTS) are pins 1& 2
connected. Connecting pins 2 & 3 will invert the polarity for one line only. Change these settings only if
you cannot your rig control program to recognize your transceiver. Most transceivers will not require any
change!
USB Jack Power
The two type B USB jacks on the PK-232SC default power output is 5 Volts @ 100 mA. This power is
derived from the computer or powered USB hub upstream from the PK-232SC. If the jumper on JP5 is
connected between pins 2 &3 (factory default), the external power supply will not be connected. The USB
circuitry will draw its power from the upstream USB device.
If you want to draw more than 100 mA. (500mA. max) from the PK-232 USB hub ports, you may connect
a 5.0 VDC @ 2A power supply to the PK-232. To do so you must enable the 5.0VDC power jack in the
middle of the PK-232SC back panel. Change the jumper on JP5 to pins 1 & 2. With the jumper in this
position, you must use the 5.0 VDC power supply so the USB circuitry will work!
USB Audio Sound Card Channel Combinations
The USB Audio sound card has two channels.
Receive Audio Input
In the factory default mode, the PK-232 sound card input (receive audio) is fed to both channels
simultaneously. Connecting JP23 pins 1 & 2 enables the factory default combined channel mode.
In optional mode, the PK-232 sound card input (receive audio) is fed to the left sound card channel and the
Aux Audio input (J10-ring on the SC connector board) is fed to the right sound card channel. Connecting
JP23 pins 2 & 3 enables the optional split channel mode.
Transmit Audio
In the factory default mode, both USB Audio sound card output channels feed the PK-232 sound card
output (transmit audio) simultaneously. Connecting JP3 pins 1 & 2 enables the factory default combined
channel mode.
In optional mode, the left sound card channel feeds PK-232 sound card output (transmit audio) and the
right sound card channel feeds the Aux Audio output (J10-tip) on the SC connector board.) Connecting
JP2 pins 2 & 3 enables the optional split channel mode.

SC Upgrades for all PK-232 models
Timewave’s customers swear by their DSP filters and PK-232 owners love the flexibility and
reliability of the most popular data controller ever built. Now with the addition of a built-in sound
card, rig control, computer isolation and total USB connectivity, the PK-232SC rolls it all into
one! The PK-232SC brings a new level of performance to the legendary PK-232 with sharp,
accurate DSP filters for all its internal data modes and dual transformer isolation for sound card
data modes. Weak signals magically appear from the noise and QRM bounces off the new DSP
filters for cleaner copy with fewer errors than the old analog filters.
More Filters, Better Filters, Automatic selection
The PK-232SC brickwall filters have tighter bandwidth and steeper skirts for improved noise and
QRM rejection. New PK-232 firmware (Ver. 7.2) allows a wider selection of filters than the original
PK-232, so the filter can match the mode. The correct DSP filter is automatically selected when you
choose an internal mode. In RTTY, Timewave’s proven Twin Peak Filters pluck the mark and space
tones from the noise and QRM for great copy. In PACTOR, the filter bandwidth automatically
changes when the baud rate shifts in response to the error rate of the link. In Morse (CW), the
operator can preset either 100 Hz or 200 Hz bandwidth. The PK-232SC is compatible with all
Windows XP, Vista, and Windows 7 software terminal programs for the PK-232.
Sound Card Interface and Rig Control
For maximum flexibility, Sound Card / TNC switching is both software and panel switch controlled.
The sound card mode selection is software controlled. For example, when operating with Radio
Operating Center software, changing to PSK31 from Pactor or MT63 is a simple menu click.
The single USB cable from your PC also moves your logic level Kenwood RX/TX/RTS/CTS, Yaesu
CAT, and Icom CIV, RS-232 and USB Rig Control interface to the back panel of your PK-232SC.
15
All the Proven Modes + All the Sound Card Modes
The PK-232SC supports all the new sound card modes in addition to all of the existing PK-232
modes - Pactor, VHF/HF Packet, AMTOR/SITOR, Baudot, ASCII, Morse, HF Weather FAX, TDM,
and NAVTEX.
The PK-232SC comes with a complete cable and connector set in addition to Timewave’s on-line and
telephone support. As always, you can upgrade any PK-232 ever built to the latest PK-232SC!
