module heart used in the GenPro 30e).
It is preferable to wait for the complete starting of your PC before powering the GenPro 30e and
connecting it to the USB port.
Depending on the installations of USB drivers already made on your computer, the installation of the USB
Driver for the GenPro 30e will not be automatic and necessary.
1- For the installation, download and extract the files that contain the Drivers in a directory on the root
of the PC hard disk (example: C:\Drivers_GenPro_30e).
2- In the directory : C:\...\Drivers_GenPro_30e\DriverInstaller, run the file DriverInstaller.exe
The following window will appear and show the progressing state of the pilots installation:
3- Once the installation is made, do the following operations in the right order :
- For the connection to the DTE (PC), connect the USB cable.
- Connect the DC regulated external power source to the GenPro 30e.
WARNING: If the following window appears, cancel it and check that you have done correctly the operations
1 and 2.

Page 19 / 37
In the section "Ports (COM and LPT)", the COM port to send AT commands is AT Command Port (UMTS)
(COM13). As the number of the port is virtual, it can change depending on the PC installations.
You can close the window of Peripheral management system.
Use a communication software like HyperTerminal of Windows
Configure the COM port of the DTE as follows:
▪ Data rate: 115200 bps,
▪ Data bits: 8,
▪ Parity: None,
▪ Stop bits: 1,
▪ Flow control: hardware.
Send the command AT↵. In HyperTerminal, the modem must reply OK.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications.
EG_GenPro30e_1006_UG_002_UK
Page 20 / 37
In the case where no communication can be established with the modem:
▪ Check the USB connection between the DTE and the modem (DCE),
▪ Check the configuration of the DTE COM port.
Example of AT commands that can be sent once the communication with the modem is validated
(commands detailed in the following paragraphs) :
▪ AT+CGSN : the reply of the modem must be a 15-digit number (beginning with
"35411802xxxxxxxx") when the serial link is correct.
▪ AT+CPIN="xxxx" : enter the code of the SIM card xxxx (if activated).
▪ AT!BAND? : check the selected frequency.
▪ AT+CSQ : check the reception level of the GSM signal received with the SIM card inserted.
▪ AT+CREG ? : check the registration of the modem on the network.
▪ ATD<numéro de téléphone> : start a data call.
▪ ATH : hang-up (end of the call).
For more information about these AT commands and their associated parameters, please refer to the
"Commands List" document of ERCO & GENER.
5.1.5 SIM card Extraction
To remove the SIM card from the modem, it is recommended to do the following operations with the modem
turned off:
- Remove the SIM card cover on the rear side.
- Press the SIM card (simple pressure) until hearing a "clic" that ensures its ejection.
- Remove delicately the SIM card from the reader.
- Replace the SIM cover.
- Do a Reset or an On/Off to take it into account.

Modem status
The modem is powered on. To be ready to work and
recognized by the network the PIN code has to be
entered and the antenna connected.
The modem is powered on, the PIN code is active, and
the modem is recognized by the network and in
communication (to make or receive calls).
The modem is not powered on or in RESET phase.
5.3 Echo Function of AT commands deactivated
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 configured 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 Machine to Machine communication 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 "Commands List" document of ERCO & GENER.

5.4 Checking the quality of the GSM reception signal
To know the reception level, the GenPro 30e must absolutely have its activated SIM card inserted.
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 lows 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 he nearest BTS which can be
ORANGE, SFR or BOUYGUES for France (Without the SIM card, the device does not recognize the current
subscription). 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:
With 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 answered value <rssi> with the help of the table hereunder.

5.5 Verification of the PIN code
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 commandAT+CPIN?
The table hereunder shows the main responses given by the modem:
Command
AT+CPIN?

For more information about AT commands, see the "Commands List" document of ERCO & GENER.
5.6 Verification of the modem registration on the GSM network
1. Ensure that a valid SIM card has been inserted in the SIM card reader of the modem.
2. Using a communication software 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 given in the table hereunder.
