The purpose of the present document is to provide a guideline to assign the physical interfaces
of the module to the services implemented by the module itself, e.g.: AT Parsers, Python, TT,
etc. The HE910/UE910/UL865 modules need to be configured in suitable way to avoid
hardware/software resources conflicts.
Scope of this guide is to cover the major ports/services arrangements offered to the user by
the modules belonging to the HE910/UE910/UL865 Families. With ports/services
arrangements is intended the allocation of an available serial port to an available service (e.g.
AT Parser, Python, TT, etc.).
This document is intended for User Application designers who want to exploit at best the
communication resources offered by the HE910/UE910/UL865 modules without run up
against resources contention among services.

Before describing the several ports arrangements supported by the HE910/UE910/UL865 Families, refer to
[4], [5] and [6], it is useful introduce the Virtual Serial Device.
Virtual Serial Device, hereafter called VSD, is a piece of software designed to run on HE910/UE910/UL865
Families. It basically manages virtual connections between the physical serial ports, accessible to the user, and
the services provided by the module. To accomplish this activity, VSD supports several Access Points used as
anchorage points for the logical connections. The following table shows the items involved in the connections
management: Physical Serial Ports, Logical Access Points, AT Parsers, Telit Trace (TT) Utilities, Services,
and Protocols.

It is advisable to remind the concept of instances and their relationships with the AT commands Parsers.
HE910/UE910/UL865 modules provide three AT Commands Parser Instances which are independent. Each
AT Commands Parser is managed by the same control software block and is connected to an ATx Access
Point as sketched in the figure below.

NOTICE: the +CFUN mode can be saved into the selected profile only if the +CFUN AT command is
entered into the module via the AT0 parser (Instance #1), refer to [2].
The several examples of the module ports arrangements reported in this document refer to the use of a generic
device (or Application Processor) connected to the module, and based on Windows PC. The physical
connection between the module and the generic device can be accomplished via different interfaces provided
by the module itself; a basic sketch is shown in fig. 2. The generic device can be developed by the user in
accordance with its needs. In general, the device can be a micro-controller developed by the user and equipped
with an operating system accomplishing the requirements of the user application. Only for practical reasons it
is use the DTE acronym to identify the device throughout the document.

NOTICE: SPI and HSIC interfaces, on the Application Processor side, must be provided by the user; the DTE
based on Windows PC and used in the next examples does not provide them. In addition, in the following
figures, SPI and HSIC interfaces are shown by the same “box” when they are not involved in connections
regarding the considered ports arrangement, see fig. 3. Physically, they are two distinct entities and this is
shown when the considered configuration involves their connections, see fig. 7, fig. 14.
Let’s assume that the factory setting5 of the module has not been changed and the USB cable is not plugged
in. Now, power on the module: the factory arrangement of the internal connections among physical ports and
“Access points” is depicted on fig. 3.

NOTICE: figures reported on the following pages and illustrating different ports arrangements show the use
of two types of trace applications in accordance with the selected configuration via AT#PORTCFG command,
refer to chapter 2.4:

TTC (Telit Trace Client tool);

3G tool (for internal use only).
Assume that the module is powered on and its configuration6 is sketched by fig. 3. Now, connect the USB
cable to the module. The module recognizes the “plug in” event and assumes the factory arrangement depicted
on fig. 6. Tab. 3 summarizes the new factory configuration. USB0÷USB6 are the seven channels provided by
the USB port.

The suitable USB drivers running on Windows PC are provided by Telit. The mapping rule between USBx
channels and virtual COMx ports is shown on chapter 2.4

AT#PORTCFG=1, refer to Chapter 2.4.
The AT#PORTCFG command manages several internal ports arrangements by means of its parameter value,
refer to [2]. The tables and figures reported on the next pages show the various ports configurations that can
be obtained changing the parameter value of the command and connecting the USB cable to the module. Use
the following sequence to make active the entered AT#PORTCFG command:

Assume to start from the configuration shown on fig. 3, it is the factory setting: #PORTCFG is 1;

Enter, for example, the AT#PORTCFG=0 command through USIF0 port, AT0 parser elaborates the
just entered command, but no actions are taken.

Power down the module;

Power on the module. The AT#PORTCFG=0 command is executed and the ports arrangement of Tab.
5 is implemented.
Before dealing with the several AT#PORTCFG configurations it is advisable to see how the USBx channels
are mapped into virtual COMx ports on the DTE side. The dialog box below shows an example of mapping.
In general, it depends on the Windows PC configuration.
From the dialog box shown on the lefts side is
derived the next mapping table:

This chapter shows an example of ports arrangement supporting CMUX protocol.
Assume that the module is configured as indicated on fig. 3: #PORTCFG=0 no USB cable plugged in. In
addition, suppose that the used DTE is a Windows PC and its device configuration is shown by fig. 16. Now,
run on the DTE the TELIT Serial Port MUX application configured as shown on fig. 17, and connect it to
COM1 physical port, refer to fig. 18. When the user starts an application (e.g. Hyper Terminal) connected to
one of the four Virtual Ports, TELIT Serial Port MUX application sends automatically the AT+CMUX=0
command to the module and the CMUX protocol is activated.
fig. 16: Physical COMx Ports
fig. 17: Virtual Serial Ports of MUX
TELIT Serial Port MUX application must be configured so that its virtual serial ports do not create conflict
with the physical or virtual serial ports already present on the Windows PC (DTE). An example is shown by
fig. 17. Tab. 27 summarizes the new configuration.

NOTICE: if you need to develop a Multiplexing Protocol running on a desired environment, e.g. a user
micro-controller, refer to [1] to get detailed information about the protocol.
This chapter shows an example of ports arrangement supporting USB channels, and CMUX protocol.
Assume that the module is configured as indicated on fig. 5: #PORTCFG=0 + USB cable plugged in. In
addition, suppose that the used DTE is a Windows PC and its device configuration is shown by fig. 4. Now,
run on the DTE the TELIT Serial Port MUX application configured as shown on fig. 20, and connect it to
USB3 channel mapped into VCOM8 virtual port as shown on Tab. 4, refer to fig. 21. When the user starts an
application (e.g. Hyper Terminal) connected to one of the four Virtual Ports, TELIT Serial Port MUX
application sends automatically the AT+CMUX=0 command to the module and the CMUX protocol is
activated.
fig. 20: Virtual Serial ports of TELIT Serial Port MUX
TELIT Serial Port MUX application must be configured so that its virtual serial ports do not create conflict
with the physical or virtual serial ports already present on the Windows PC (DTE). An example is shown by
fig. 20.
It is worth noting that the AT0 (instance # 1) is disconnected from USIF0 and connected to
USB3/VCOM8/VCOM20VC1, the TTC stays on USB1. The table below summarizes the new ports

Having at disposal several ports configurations, the following question arises when the user sets different
configurations in sequence: is the last configuration affected by the previous ones?
There are two methods to change module ports arrangement without turn off/on the module:


Plug in/out the USB cable;
Enter the AT+CMUX=07 command.
NOTICE: to execute the entered AT#PORTCFG command and get the desired ports arrangement it is needed
to turn off/on the module.
The modules provide the following policy: regardless of the actions or commands sequence that user has used
to set the module into the desired ports configuration the module must always enter the last requested
configuration. Follow two examples.
Example 1
Module:
let’s suppose that its ports configuration is summarize in Tab. 5.
User action:
the user runs on the Windows PC the TELIT Serial Port MUX application so configured:
Virtual Ports COM20÷COM23 logically connected to COM1.
PC:
it provides the required Virtual Ports. When the user starts an application (e.g. Hyper
Terminal) connected to one of the three Virtual Ports (the fourth one is spare), TELIT Serial
Port MUX application sends the AT+CMUX=0 command to the module.
Module:
in accordance with the received command, the involved AT Parser starts the CMUX protocol.
The module enters the configuration shown on fig. 18.
User action:
now, the user connects USB cable.
Module:
it enters the configuration shown on fig. 5.
PC:
it provides seven new virtual “COM” logically connected to the seven USB channels. The
CMUX protocol is disabled and the TELIT Serial Port MUX application running on Windows
PC is no more connected to the module, it should be closed. COM1 is ready for new
applications (e.g. Hyper Terminal).
User action:
now, the user disconnects USB cable.
Module:
it enters again the configuration shown on Tab. 5
7
TELIT Serial Port MUX application automatically sends the AT+CMUX=0 command to the module , see chapters 0,
2.6.
Example 2
Module:
let’s suppose that its configuration is summarized in Tab. 5.
User action:
the user connects USB cable.
Module:
in accordance with the user action, the module enters the configuration shown on fig. 5.
PC:
it provides seven virtual “COM” required by USB drivers to logically connect the seven
USBx channels.
User action:
the user runs on the Windows PC the TELIT Serial Port MUX application so configured:
Virtual Ports VCOM20 ÷ VCOM23 logically connected to USB3VCOM8.
PC:
it provides the required Virtual Ports. When the user starts an application (e.g. Hyper
Terminal) on a Virtual Ports, TELIT Serial Port MUX sends the AT+CMUX=0 command to
the module.
Module:
in accordance with the received command, the involved AT Parser starts the CMUX protocol.
The module enters the configuration shown on fig. 21.
User action:
now, the user disconnects USB cable.
Module:
it enters the configuration shown on Tab. 5.
PC:
discards the seven virtual “COM” logically connected to the seven USBX channels. The
CMUX protocol is disabled, TELIT Serial Port MUX application running on Windows PC is
no more connected to the module, and it should be closed.
From the above mentioned examples it may be inferred that the last required port configuration overrides the
previous one.
The modules equipped with GPS receiver can send NMEA sentences on different physical ports in accordance
with the current ports configuration. In general, NMEA sentences run on the physical port used by the
operator to enter the AT$GPSP and AT$GPSNMUN commands: it means that AT commands and NMEA
sentences share the same physical port at the same time.
It is assumed that the module is configured as shown on Tab. 5: #PORTCFG=0, no USB cable. Now, enable
GPS/NMEA sentences via AT$GPSP=1 and AT$GPSNMUN=1,… commands entered through USIF0 port,
see [2]. The entered AT commands are elaborated by AT0 parser and after that, the module sets up the ports
configuration summarized on Tab. 30. See also fig. 22.

The HE910/UE910/UL865 modules provide the Python programming language to offer to the user a tool to
develop control scripts in accordance with its communication and hardware needs, see [3]. As shown on fig.
27 the VSD provides two access points called VHWDTE0 and VHWDTE1. MDM and MDM2 Python
modules are logically connected respectively to VHWDTE0 and VHWDTE1 access points.
Let’s assume that the module is using the ports configuration summarized on Tab. 7 (factoring setting), no
USB cable is plugged in. When the Python script runs the Python instruction import MDM 8 , the VSD
disconnects the USIF0/AT0 logical connection and establishes the logical connection VHWDTE0/AT0;
consequently the Python script can access AT0 parser. In the same way, import MDM2 instruction requires to
the VSD to establish the logical connection VHWDTE1/AT1. The fig. 27 shows that USIF0 is disconnected
and can not be used by an external device.
Python script can run another Python software module to use the USIF0 port using the instruction import
SER. The fig. 28 shows the new connection: through the physical port USIF0 it is possible to be connected
with the Python script.
The three Python software modules (MDM, MDM2 and SER) use three independent resources: USIF0
physical port, AT0, and AT1 Access Points. No resources contention can arise among them. As a rule, we can
say that the MDM, MDM2 and SER instructions steal the above mentioned resources regardless their current
owner.
As shown in the next pages there are other Python modules to create logical connection between a physical
port and an Access point. To have detailed information on the software versions supporting different Python
modules refer to document [3]. Here are some figures showing different logical connection configurations.

The Python software modules MDM, MDM2, SER, and SER2 use four independent resources: USIF0, USIF1
physical ports, and AT0, AT1 Access Points. No resources contention can arise among them. As a rule, we
can say that the MDM, MDM2, SER, and SER2 instructions steal the resources regardless their current owner.
In accordance with the installed software version, Python script can run the Python software module to use the
USB0 channel using the instruction import USB0 and the access point PYUSB0. The figure below shows the
new connection: the USB0 channel is connected to Python script via PYUSB0/USB0.

As a rule, we can say that the MDM, MDM2, SER, and USB0 instructions steal the resources regardless their
current owner.
It is assumed that the user needs to debug a new Python script. To perform the debugging session, the user
forces the module into #PORTCFG=3 configuration, refer to Tab. 11. Suppose that the Python script runs:
import MDM, import MDM2, import SER and print instructions. The figure below sketches the actions
results of the first tree instructions. Moreover, it shows that when #PORTCFG=3 configuration is used, at the
start up of the Python script the USIF1 is disconnected from AT2 Access point and connected to Python
