Presentation
Entirely dedicated to the wireless markets throughout the world, the GenPro 53e (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 53e is a robust, reliable and long life product. Its very compact metal case makes it ideally
adapted to onboard standards.
The modem is Quad-Bands (850/900/1800/1900 MHz) GSM/GPRS Class 10 or EDGE*.
The GenPro 53e 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 Commands List EG_EasePro_Vx_CL_yyy_UK of ERCO & GENER).
Autonomous mode (optional): Once configured, the modem is autonomous, it cyclically registers the
positions and tranmits them automatically to the client’s application via different services: SMS, GSM
Data, TCP socket GPRS (see EG_EasePro_Vx_CL_yyy_UK 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.
By default, the GenPro 53e provides:
2 RS232ports,
a 1-Wire interface
TOR inputs/outputs, 5 inputs, 3 outputs
2 analogs inputs
a back-up battery
a 3-axis accelerometer
The GenPro 53e can be equiped with the options Bus CAN and DUAL SIM.
Its protocols of IP connectivity integrated in the embedded application EasePro, are also available under
EGM libraries for a specific development, allowing a quick installation of embedded telematic solutions with
high added-value.

pin Micro-FIT connector (RESET).
The modem Reset is made when the RESET signal (pin 10) is held at a low level during 10ms.
This signal must be considered as a way of reseting the modem in case of emergency only.
For more details concerning the modem RESET, see the paragraph 7.7.2 RESET sequence
See the table of the paragraph 8.2.6 RESET signal for the electrical characteristics.
5.2 Specific recommendations for the use of the modem in vehicles
The power supply connector of the modem GenPro 53e must NOT be connected directly to
the battery of the vehicle.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications
EG_GenPro53e_1040_UG_003_UK Page 29 / 71
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.
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
EG_GenPro53e_1040_UG_003_UK Page 30 / 71
5.2.2 Technical constraints in trucks
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).
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 of 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.

This led is free. It is left at the user’s disposal. It is controlled via a command through the ARM. This
command is currently under development. Contact us.
5.3.5 LED 6
This led is not used.
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.
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 reception error code (g).
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.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications
EG_GenPro53e_1040_UG_003_UK Page 33 / 71
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 to 7
See standards ETSI
GSM 05.08
1 to 10 -111 to -95 dbm Insufficient
11 to 30 -93 to -53 dbm Sufficient
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.
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
+CPIN : ERROR
+CPIN : READY
AT+CPIN?
+CPIN : SIM PIN
The SIM card is absent or not
recognized
The PIN code is correct

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.
Command Response Interpretation
+CREG : 0,0
+CREG : 0,2 or 0,3
AT+CREG?
+CREG : 0,1
+CREG : 0,5

6.2 "ERROR" message
This paragraph is valid only if the modem contains the EGM standard library or the
EasePro_Vx application.
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 53e 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: check it (see the document "EG_EGM_CL_xxx_yy" of
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 after having sent the command AT+CMEE, see the
document "EG_EGMCL_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).
6.3 "NO CARRIER" message
This paragraph is valid only if the modem contains the EGM standard library or the
EasePro_Vx application.
If the modem returns the message "NO CARRIER" after an attempted call (voice or data), check the table

7 Functional Description
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.
A correct functioning of the modem in communication cannot be guaranteed if the input tension
(V+BATTERY) falls below 5.5 V and if the battery is not charged enough.
Descriptions and non-contractual illustrations in this document are given as an indication only.

7.2.2 Internal battery
7.2.2.1 Presentation of the internal battery
The battery is fixed inside the GenPro 53e. It is connected to an additional charging circuit cabled on the
mother board of the GenPro 53e.
This battery allows to maintain the GenPro 53e 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.
When the battery is completely discharged, 3 hours are necessary to obtain a new complete charge. It is
normal that the box gently heated in this case.
The autonomy of the battery essentially depends on the mode of use of the GenPro 53e (attachment in
GSM/GPRS, Inputs/Outputs, RS232 connected...).
When the temperature exceeds 45 °C inside the box, the protection of the battery management
triggers. The battery will not be charged.
If the battery is present, prepare the modem for storage or transport conditions, in order to
limit high discharges of the battery. For that, see § 5.9 Turning off the modem
7.2.2.2 Specifications of the internal battery
The external power supply of the GenPro 53e 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 Instructions and restrictions of use
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 10 of the 16-pin micro-FIT connector) 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 for
any intervention on the battery: the device must be returned to the factory.
Do not throw the modem and the battery on the fire.

EG_GenPro53e_1040_UG_003_UK Page 43 / 71
7.2.3 Protections of the power supply
The modem is protected by a F2 A / 32 V fuse directly assembled on the power supply cable supplied with
the modem.
Fuse reference: Mini Blade car 2A - 32V (code couleur : grey)
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.
It is necessary to use the supply cable delivered with the modem, otherwise the modem will
not be protected.
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.
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) if the GenPro 53e contains the EGM standard library (see
the documents "EG_EGM_CL_xxx_yy" of ERCO & GENER) in this case, 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.
7.3.2 Serial link RS232_0
The signals of the RS232_0 are available on the 16-pin Micro FIT connector and on the 9-pin Sub D

7.8 WatchDog
The Hardware WatchDog function allows the surveillance of the GenPro 53e 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 Audio
The audio interface is standard to connect an equipment like a telephone handset.
The modem contains the EGM standard library (see the documents "EG_EGM_CL_xxx_yy" of ERCO &

9 Security recommendations
9.1 General security
It is important to respect the specific regulations concerning the use of radio equipment, in particular with the
possible risks of interference due to radio frequency (RF). Please respect carefully the following security
advices.
Turn off your GSM modem:
On an aircraft, the use of cellular telephone can endanger the plane operations; disturbing the cellular
network is illegal. The non-observance of this instruction can lead to the suspension or the exclusion
of the cellular phone services, or even to a trial, or both,
At a refueling station,
In any area with a potential explosive atmosphere that could cause an explosion or a fire,
In hospitals and other places where medical equipment may be used.
Restrictions of use of radio equipments in:
Fuel warehouses,
Chemical factories,
Places where destruction operations are in the running,
Other places where signs indicate that the use of cellular phones is prohibited or dangerous.
Other places where you should normally turn off the engine of your vehicle.
There can be a danger associated with the use of your GSM modem close to insufficiently protected medical
devices such as acoustic devices and pacemakers.
Consult the manufacturers of medical equipment to know if it is adequately protected.
Using your GSM modem close to other electronic equipments may also cause interferences if the equipment
is insufficiently protected.
Pay attention to the warnings and the recommendations of the manufacturers.
The modem is designed to be used with "fixed" and "mobile" applications:
“Fixed" application: The GSM modem is physically linked to a site and it is not possible to move it
easily to another site.
"Mobile" application: The GSM modem is designed to be used in various places (other than fixed) and
is intended to be used in portable applications.
The modem must be used at more than 20cm from the human body.
This equipment is supplied in Very Low Security Voltage and at non-dangerous energy level.
