PRÉSENTATION
Entirely dedicated to the wireless markets throughout the world, the GenPro 2xe (Application On Board)
allows a simple and rapid integration of GSM / GPRS Quad-Band (850/900/1800/1900 MHz) connectivity into
M2M applications.
The GenPro 2xe is a robust, reliable and long life product. Its very compact metal case makes it ideally
adapted to onboard standards
The range GenPro 2xe comes in two versions: GenPro 22e and GenPro 23e
Optional back-up battery and accelerometer associated with EGM (Erco & Gener Middleware) development
tools, offer the possibility for the personalisation of supplementary applications
Unlike GenPro 22e, GenPro 23e has 3 inputs and 1 digital output
The GenPro 2xe has 3 operating modes:
External mode (standard): The driving is made by an external application. The modem is used with
the AT commands set (see EG_EGM_CL_xxx_yy of ERCO & GENER).
Autonomous mode (optional): Once configured, the modem is autonomous; it cyclically registers the
positions and transmits them automatically to the client’s application via different services: SMS,
GSM Data, TCP socket GPRS (see EG_EasePro_01_CL_xxx_yy of ERCO & GENER).
Specific development mode: the EGM development tool allows to develop personalized embedded
application. For more information concerning the tools and the training, please contact our sales
department.
The GenPro 2xe provides digital inputs/outputs allowing the creation of embedded telematic solutions
with high added value.
This document describes the modem and provides the following information:
- General presentation,
- Functional description,
- Available basic services,
- Installation and use of the modem (first level),

EG_GenPro2xe_1003_UG_005_UK Page 25 / 63
5.2 Specific recommendations for the use of the modem in vehicles
The power supply connector of the modem GenPro 2xe must NOT be connected directly to
the battery of the vehicle.
5.2.1 Recommended Connection on the battery of a truck
All lorries have a Circuit Breaker outside the cabin. The circuit breaker is used for security reasons: for
example, if a fire breaks out in the electric box of the lorry, the driver can cut off the power source and avoid
more damage (explosion).
The circuit breaker is connected to the ground of the lorry, usually connected to the fuse box.
Most of lorry circuit breakers do not cut off the PLUS of the battery, but cut off the ground.
GenPro 2xe
The scheme above shows a recommended power connection where the connection of the modem ground is
not directly connected to the battery, but connected after the circuit breaker (to the ground of the lorry or in
the fuse box).
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications.
Dct_427_00
EG_GenPro2xe_1003_UG_005_UK Page 26 / 63
5.2.2 Technical constraints in truck
It is highly recommended NOT to connect the modem supply directly to the battery but to the circuit breaker.
Otherwise the modem can be damaged when the lorry is starting up if the circuit breaker is closed (in this
case, the ground of the lorry and the ground of the battery will be connected via the modem as described in
the scheme below)
GenPro 2xe
Example of forbidden electrical connection (risk of damage on the modem)
The scheme above shows an example of electrical connection that could damage the modem due to the fact
that the ground connection is directly connected to the battery ground.
In fact in this example, when the circuit breaker is open, the current escapes via the modem and the
electrical circuits of the lorry (the dashboard for example). And when the motor’s starter is used, it will
destroy the cables or the modem.
Moreover, the internal circuits of the modem are not designed to resist to a current about 60 A (when starting
the lorry), or they would be destroyed.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications.

5.3 Modem leds
5.3.1 Without library
The GenPro 2xe does not contain any library. The led is off.
5.3.2 With EGM standard library
The led remains off.
5.3.3 The application ERCO & GENER EasePro-01
This application is currently under development. Contact us.
5.3.4 The owner application
The GenPro 2xe contains your application. The led status depends on your parameters.
5.4 Echo function of the deactivated AT commands
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, if no echo is returned when entering an AT command, it means that:
- the "local echo " of your communication software (like Hyperterminal) is not activated,
- the echo function of the modem has been deactivated.
The echo function can be set with the command ATE ; it requires a back-up with the command AT&W.
To activate the echo function of the modem, enter the command ATE1.
When sending AT commands to the modem using a communication software, it is recommended to:
- Deactivate the "local echo" parameter in your communication software (like Hyperterminal),
- Activate the echo function of the modem (the command ATE1).
For a communication Machine to Machine with the modem, it is recommended to deactivate the echo
function of the modem (the command ATE0) in order to avoid the CPU receiving redundant responses.
For more information about the ATE commands, see the document "EG_EGM_CL_xxx_yy" of ERCO &
GENER.

Dct_427_00
EG_GenPro2xe_1003_UG_005_UK Page 28 / 63
5.5 Checking the quality of the GSM reception signal
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, the modem will be able to make a call only if the received GSM signal is sufficient.
The command AT+CSQ allows to know the reception level (rssi) of the signal sent by the closest GSM Base
Transceiver Station (BTS), as well as the receive bit error rate (ber).
When the SIM card is inserted and the PIN code entered, the command AT+CSQ allows to measure the
signal from the BTS of the subscribed operator network.
This command can also be used without the SIM card, it indicates in this case the nearest BTS which can be
ORANGE, SFR or BOUYGUES for France (Without SIM card, the current subscription is not recognized).It is
therefore advisable to do the measure when the SIM card is present.
To check the quality of the GSM signal, do the following operations:
Use a communication software like Hyperterminal, enter the command AT+CSQ.
The response is in the following format:
+CSQ : <rssi>, <ber> with:
<rssi> = indicates the reception level,
<ber> = receive bit error rate.
Check the returned value <rssi> with the help of the table below.
<rssi> Value Gain in dbm Interpretation <ber> Value Interpretation
0 -113 dbm Insufficient 0 à 7
1 à 10 -111 à -95 dbm Insufficient
11 à 30 -93 à -53 dbm Insufficient
31 (max) -51dbm Perfect
99 Unknown/not detectable 99 Unknown/not detectable
The GSM modem works normally with a minimum <rssi> between 11 and 15.
Bellow 10, the signal level is insufficient; the modem cannot work depending on the geographical situation or
the vehicle mobility. Above 15, the signal is sufficient.
For more information about AT commands, see the document "EG_EGM_CL_xxx_yy" of ERCO & GENER.
See ETSI GSM 05.08

5.6 Verification of the PIN code
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, the PIN code is essential in order to make a call or to accept a response coming from
the GSM network. This code is held in the SIM card and can be modified by the user.
To check that the PIN code has been entered, use a communication software like Hyperterminal, and enter
the command AT+CPIN?
The table below shows the main responses given by the modem:
Command Response Interpretation
AT+CPIN?
+CPIN : ERROR
The SIM card is absent or not
recognized
+CPIN : READY
+CPIN : SIM PIN
+CPIN : SIM PUK
For more information about AT commands, see the document "EG_EGM_CL_xxx_yy" of ERCO & GENER.
The PIN code is correct
The PIN code is wrong or not entered
yet
The PUK code is required
5.7 Verification of the modem registration on the GSM network
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case:
1. Ensure that a valid SIM card has been inserted in the SIM card reader of the modem.
2. Using a communications application like HyperTerminal, enter the following AT commands:
a. AT+CPIN="xxxx" to enter the PIN code. The user has only 3 attempts to enter the PIN code.
After the third attempt, only a second code (code PUK) supplied by the operator, will allow you
to chose a new PIN code.
b. AT+CREG? to check the registration status on the network. The response will be of the
following format: +CREG : <mode>, <stat> with:
<Mode> = configuration of the registration message not solicited,
<Stat> = registration status.
3. Check the registration status according to the value returned in the table hereunder.

6.2 "ERROR" message
The modem returns a message "ERROR" (in response to an AT command) in the following cases:
The COM port is not directed to the modem GenPro 2xe but to another modem. Enter ATI1, and
the response must be Enabler_III.... Any other response indicates a dialog with another modem.
In this case, check the COM port used in the Hyperterminal.
The syntax of the AT command is incorrect : then check it (refer to document
"EG_EGM_CL_xxx_yy" ERCO & GENER.
The syntax of the AT command is correct, but transmitted with wrong parameters:
- Enter the command AT+CMEE=1 to obtain an error message with its error code instead of a
simple “ERROR” message,
- Enter again the AT command which previously caused the "ERROR" message in order to obtain
the error code.
In case of an error code, the response of the modem may be:
+CME ERROR : < error code >
For more information about the error codes returned by the command AT+CMEE, see the document
"EG_EGM_CL_xxx_yy" of ERCO & GENER.
It is strongly recommended to systematically allow the modem to return the error codes (enter
the command AT+CMEE=1).

7.1 Architecture
7.2 Power supply
7.2.1 General presentation
The modem must be powered by an external DC tension (V+BATTERY) between +5.5V and +32V.
The regulation of the modem power supply is made with a DC/DC internal converter in order to supply all the
necessary internal DC tensions.
For the GPS module, another regulation is made for its internal power supply.
A correct functioning of the modem in communication cannot be guaranteed if the input tension
(V+BATTERY) falls below 5.5 V.

7.2.2 Internal battery option
7.2.2.1 Presentation of internal battery option
The battery is fixed inside the GenPro 2xe . It is connected to an additional charging circuit cabled on the
mother board of the GenPro 2xe .
This battery allows to maintain the GenPro 2xe functioning in the absence of its external power supply
(power supply connected on the Micro-FIT 4-pin female connector).
The internal charging circuit allows to keep permanently the charge of the battery from the external power
supply.
EG_GenPro2xe_1003_UG_005_UK Page 36 / 63
When the battery is completely discharged, 3 hours are necessary to obtain a new complete charge.
normal that the box gently heated in this case.
The autonomy of the battery essentially depends on the mode of use of the GenPro 2xe (attachment in
GSM/GPRS, Inputs/Outputs, GPS power supply, RS232 connected...).
The internal battery option is not cabled by default and its assembling must be made by us in
our factory (contact us). The option is identified by a label (see paragraph 2.3 Modem labels)
7.2.2.2 Specifications of the internal battery option
The external power supply of the GenPro 2xe remains unchanged (from +5,5V to 32V DC). The internal
regulator of charge supplies the 4.2V tension necessary for the battery charge.

7.2.2.5 Instruction and restrictions of use
The internal battery option is not cabled by default and its implementation must be made by us in our factory
(contact us).
When the battery is completely discharged, it takes around three hours to obtain a complete charge.
When the battery is connected and charged, it is not possible to do an On/Off of the device. Only putting the
Reset input (pin 14) to the ground or sending the command AT+EGMRST allows a reset of the modem.
The battery cannot be replaced or modified by the user. The device must not be opened, under any
circumstances. For any problem concerning the battery: the device MUST be returned to the factory.
Do not throw the modem and the battery on the fire.
7.2.3 Protections of the power supply
The modem is protected by a F2.5A / L250V or 2A / 32V fuse directly assembled on the power supply cable
supplied with the modem.
EG_GenPro2xe_1003_UG_005_UK Page 38 / 63
The modem is also internally protected against tension peaks of more than 32 V.
Filter guarantees: EMI/RFI protection in input and output and signal smoothing.
7.3 RS232 serial link
7.3.1 general presentation
The RS232 interface provides an adaptation of the tension levels (V24/CMOS ⇔ V24/V28) between the
GSM/GPRS module (DCE) and the communication port of a PC (DTE).
The RS232 interface is internally protected (ESD protection) against electrostatic peaks coming from the
RS232.
Filter guarantees: EMI/RFI protection in input and output and signal smoothing.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications.
Dct_427_00
EG_GenPro2xe_1003_UG_005_UK Page 39 / 63
The available signals on the RS232 serial link are:
TX data (CT103/TX) : Data emission,
RX data (CT104/RX) : Data reception,
Request To Send (CT105/RTS) : Request to send,
Clear To Send (CT106/CTS) : Ready to send,
Data Terminal Ready (CT108-2/DTR) : Data terminal ready,
Data Set Ready (CT107/DSR) : Data set ready,
Data Carrier Detect (CT109/DCD) : Signal detection (optional) and Buzzer output (by default),
Ring Indicator (CT125/RI) / 3.8V : Call indicator (optional) and 3.8V power supply for GenBlue 15e
or Gen10400 (by default).
Normalized signals of a RS232 serial link
The RS232 interface was designed to allow a certain flexibility in the use of the serial interface signals. In
fact, after the setting (see command AT+IFC), the modem can work in 3-wire mode (using only the signals
TX, RX, GND), but the use of the signals TX, RX, GND, CTS, RTS is required for a GPRS application, which
is not the case for the signals DTR, DSR, DCD/Buzzer and RI/3.8V that may not be used.

7.5 Inputs/Outputs functioning - GenPro 23e
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &
GENER) in this case, the modem GenPro 23e provides 3 inputs (opto-coupled) and 1 output (open collector)
available for an external use.
The input / output are not available on the GenPro 22e.
These functions can be controlled by AT commands:
AT+GPIOSET for a writing access to a GPIO with the GPIO used as an output,
AT+GPIOGET for a reading access to the GPIO with the GPIO used as an input.
AT+GPIOSET=10 This command is used to control the output. By default, the output is cabled as an open
collector. To control it:
AT+GPIOSET=<n>,<x> with:
<n> = 10 : Only 1 output available on the GenLoc 31e AOB (so n=10),
<x> = 0 : Output OFF
1 : Output ON
Examples:

7.7 RESET
7.7.1 General presentation
This signal allows to make a Hardware RESET of the modem. In fact, this pin is used to force a RESET of
the modem, doing a low level during at least 10 ms.
This signal must be used only in case of emergency RESET.
This signal must be driven with an open collector assembly:
pin 14 (RESET) at 0, for the modem Reset,
pin 14 (RESET) at 1, for normal mode.

7.7.2 RESET sequence
To activate the emergency RESET sequence, the RESET signal must be put to a low level during at least 10
ms.
A soon as the modem has been RESET, if a SIM card is inserted inside the SIM reader, you must wait for
the end of the initialization before accessing it again. Moreover, the acquisition time of a GPS position will
have to be taken into consideration.
• Using the RESET does not restore the factory parameters.

7.8 WatchDog
The Hardware WatchDog function allows the surveillance of the modem software activity: the Software
management of the WatchDog is implanted in the embedded application by default. In the case of a
development (EGM) it must be implanted in the embedded application of the final customer.
If the software activity is interrupted, the WatchDog component starts a hardware Reset.
The WatchDog function is active only if the SIM card is present. That’s why, it is imperative to remove the
SIM card during a Firmware updating.

7.9.1 Microphone inputs
The microphone inputs are assembled in differential to reduce the noise in common mode and the TDMA
noise.
They include the functionality for a microphone like Electret (0.5 mA and 2 Volts) and they are ESD
protected. This Electret microphone can be directly connected to these inputs allowing an easy connection to
a telephone handset.
The microphone impedance is around 36 k.
The gain of the microphone inputs is internally adjusted by a differential amplifier and can be adjusted with
the command AT+PREAMP (see the document "EG_EGM_CL_xxx_yy" of ERCO & GENER). The amplifier
has a gain of 25.6 dB and a Bias generator that supplies an external tension of 2 or 2.5V for the microphone
