EG_GenPro78e_1003_UG_007_UK Page 21 / 41 5.5 Verifying GSM receive signal quality The modem will be able to establish a call only if the received GSM signal is of a sufficient level. The command AT+CSQ will return the reception level (rssi) of the signal sent by the closest GSM Base Transceiver Station (BTS), as well the receive bit error rate (ber).
EG_GenPro78e_1003_UG_007_UK Page 22 / 41 5.6 Verifying the PIN code The PIN code is essential in order to make a call or to accept a call from the GSM network. The PIN code is held on the SIM card and can be modified by the user. To verify a previously entered PIN code, use a communication application and enter the command AT+CPIN? The table below shows the main responses from the modem:...
EG_GenPro78e_1003_UG_007_UK Page 23 / 41 5.8 Main AT commands (HAYES) The table below shows at a quick glance the main AT commands useful for the control of the modem.

The modem returns the message “ERROR” (in response to an AT command) in the following cases : • The COM port is not directed to the GenPro 18e but to another modem. Enter the command ATI1. The response should be Enabler_III..All other responses indicate a dialog with another modem.
EG_GenPro78e_1003_UG_007_UK Page 26 / 41 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 a problem to obtain the error code. In the case of an error, the response is in the form : +CME ERROR : <error code>...

EG_GenPro78e_1003_UG_007_UK Page 28 / 41 7.2 Power supply 7.2.1 General The modem must be powered (V+BATTERY) by an external regulated DC power source of between 5.5V and 32V. The modem’s various internal DC voltages are provided by an internal DC/DC converter. The correct functioning of the modem cannot be guaranteed if the input voltage (V+BATTERY) falls below 5.5V.
EG_GenPro78e_1003_UG_007_UK Page 29 / 41 7.3 RS232 serial link 7.3.1 General The RS232 interface provides a level translation (V24/CMOS ⇔ V24/V28) between the GSM module DCE) and the PC COM port (DTE). The RS232 interface is protected internally (ESD protection) against external electrostatic spikes. Filter guarantees: Input/output EMI/RFI protection, Signal smoothing.
The auto-baud mode is controlled by the command AT+IPR. This function is explained in detail in the ERCO & GENER “Commands List”. Note: By default, the GenPro 18e is delivered with the RS232 interface configured to 9600 bps, no parity, 8 data bits, 1 stop bit.
