PAGE 16
EG_GenPro78e_1003_UG_007_UK Page 16 / 41 5.1.3 Communication with the modem Connect the RS232 cable between the DTE (the COM port) and the modem (DCE). Configure the DTE RS232 port as follows: ▪ Data rate: 9600 bps, ▪ Data size: 8 bits, ▪ Parity: None, ▪ Stop bits: 1, ▪ Flow control: hardware. Via the DTE (a PC running a communications application such as HyperTerminal), enter the command AT(CR). The modem should reply with OK.

EG_GenPro78e_1003_UG_007_UK Page 17 / 41 5.1.5 Re-initialisation of the modem The hardware RESET signal is available on pin 14 of the 15-pin Sub HD connector. The modem is reinitialised when this RESET signal is held at a low level for at least 500µs. WARNING: This RESET signal should be considered as a means of re-initialising the modem in cases of emergency only. For further details concerning the RESET of the modem, see the chapter 7.6 RESET. 5.

EG_GenPro78e_1003_UG_007_UK Page 18 / 41 GenPro 18e The diagram above shows a recommended connexion, where the modem is connected after the circuit breaker to the ground of the lorry (or in the fuse box) and NOT directly to the earth of the battery Description and non-contractual illustrations in this document are given as an indication only. ERCO & GENER reserves the right to make any modifications.
PAGE 19
EG_GenPro78e_1003_UG_007_UK Page 19 / 41 5.2.2 Technical constraints in lorry It is highly recommended to NOT connect the modem supply directly the battery but instead to the circuit breaker. Otherwise the modem may be damaged when the lorry is starting and the circuit breaker is closed.

EG_GenPro78e_1003_UG_007_UK Page 20 / 41 5.3 GSM indicator LED The state of the modem is indicated by the GSM LED located on the rear side of the modem, close to the SIM holder (see chapter 3.1 Physical Description). The table below shows the meaning of the different states of the GSM LED : GSM LED ON OFF LED activity LED on fixed Modem state The modem is powered, it is ready to function but not yet recognised by the network; the PIN code has not yet been entered or the antenna is not connected.
PAGE 21
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).
PAGE 22
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.

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. For further information concerning the complete command set see the ERCO&GENER "Commands List”. Table: Main AT commands used with the modem.
PAGE 24
EG_GenPro78e_1003_UG_007_UK Page 24 / 41 5.9 Powering down the unit There is no specific AT command to be transmitted to the GenPro 18e modem before removing the power. 5.10 Updating the modem software So as to be able to benefit from the latest functions of the GenPro 18e, a procedure is used which will upgrade the software in the modem. This consists of downloading the software into the internal Flash memory via the RS232 serial link available on the 15-pin Sub HD connector.

Table: possible causes and solutions for RS232 communication problems If the modem...
PAGE 26
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 : For further information about the error codes returned by the command AT+CMEE, refer to the ERCO & GENER "Commands List".

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. 7.2.2 Protection The modem is protected by an in-line 2.5A / 250V fuse in the power supply cable supplied with the modem.
PAGE 29
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.

EG_GenPro78e_1003_UG_007_UK Page 30 / 41 7.3.2 Auto-baud mode The auto-baud mode allows the modem to automatically detect the transmission speed used by the DTE. (only from 1200 up to 115200 bps). 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.
