Connect the RS232 link between the DTE (the COM port) and the modem (DCE). Configure the RS232 port of the DTE as follows: ▪ Bits per second ..... : ▪ Data Bits ................ : ▪ Parity ..................... : ▪ Stop Bits ................ : ▪ Flow control ...........
PAGE 25
EG_GenPro25e_1055_UG_000_UK Page 25 / 66 With this status, the two leds are OFF. In the case where no communication can be established with the modem: ▪ Check the RS232 connection between the DTE and the modem (DCE), ▪ Check the configuration of the COM port of the DTE. 5.1.3.3 The ERCO & GENER application EasePro-V2.xx The GenPro 25e contains the application EasePro_V2.xx. Send the command ATI8. The modem returns the version (example of display) EasePro V2.

EG_GenPro25e_1055_UG_000_UK 5.2 Page 26 / 66 Specific recommendations for the use of the modem in vehicles The power supply connector of the modem GenPro 25e must NOT be directly connected to the battery of the vehicle. 5.2.1 Recommended connection on the battery of a truck All trucks have a Circuit Breaker outside the cabin.
PAGE 27
EG_GenPro25e_1055_UG_000_UK 5.2.2 Page 27 / 66 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 truck is starting up if the circuit breaker is closed (in this case, the ground of the truck and the ground of the battery will be connected via the modem as described in the scheme below).

EG_GenPro25e_1055_UG_000_UK Page 37 / 66 6 Trouble Shooting This section of the document describes the problems that may be encountered when using the modem. 6.1 Problem of communication between the modem and the RS232 link (V24) If the modem does not respond to the AT commands via the RS232 link, see the table below for the possible causes and the solutions. Table 14 : Solutions when there is no dialogue between the modem and the RS232 link If the modem...
PAGE 38
EG_GenPro25e_1055_UG_000_UK 6.2 Page 38 / 66 "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 25e but to another modem. Enter ATI0, the response must be "LEON-G100-xxx-yy". Any other response indicates a dialog with another modem. In this case, check the COM port used in Hyperterminal.
PAGE 39
EG_GenPro25e_1055_UG_000_UK 6.3 Page 39 / 66 "NO CARRIER" message If the modem returns the message "NO CARRIER" after an attempted call (voice or data), see the table below for the possible causes and their solutions. Table 15 : Solutions when a message "NO CARRIER” is returned If the modem...

PAGE 41
EG_GenPro25e_1055_UG_000_UK 7.2.2 Page 41 / 66 Internal battery option The battery is fixed inside the GenPro 25e. It is connected to an additional charging circuit cabled on the mother board of the GenPro 25e. This battery allows to maintain the GenPro 25e functioning in case of 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 charging of the battery from the external power supply.
PAGE 42
EG_GenPro25e_1055_UG_000_UK 7.2.2.2 Page 42 / 66 Charge voltage and power supply voltage The following table shows the consumptions of the modem when the GSM antenna and the SIM card are present. These values were measured after a complete discharge of the battery. Table 18 : Consumption of power supply (2*) GSM CONDITIONS T=25°C External supply voltage I Charge Nom.(mA) Without RS232 @ 7.
PAGE 43
EG_GenPro25e_1055_UG_000_UK 7.2.2.4 Page 43 / 66 Instructions and restrictions of use The internal battery option is not cabled by default and its implementation must be made by ourselves 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 present and charged, the fact of removing the power supply +V DC does not turn OFF the equipment. For this, see §5.11 Turning OFF the modem.
PAGE 44
EG_GenPro25e_1055_UG_000_UK Page 44 / 66 Figure 19 : Normalized signals of a RS232 serial link The RS232 interface was designed to allow 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 and RI which may not be used. 7.3.
PAGE 45
EG_GenPro25e_1055_UG_000_UK 7.4 Page 45 / 66 Inputs/Output functioning The modem contains an EGM application: in this case, the modem GenPro 25e provides 3 inputs (optocoupled) and 1 output (open collector) available for an external use. These functions can also 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. 7.4.
PAGE 46
EG_GenPro25e_1055_UG_000_UK 7.5 Page 46 / 66 BOOT This signal must NOT be connected, NOT used. Its use is strictly reserved for the manufacturer. 7.6 RESET 7.6.1 General presentation This signal allows performing a Hardware RESET of the modem. In fact, this pin is used to force a RESET of the modem by putting it downwards during at least 10 ms. This signal must be used only in case of emergency RESET.
PAGE 47
EG_GenPro25e_1055_UG_000_UK 7.6.2 Page 47 / 66 RESET sequence To activate the emergency RESET sequence, the RESET signal must be put downwards during at least 10 ms. As 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. Figure 20 : RESET sequence Using the RESET does not restore the factory parameters. 7.
PAGE 48
EG_GenPro25e_1055_UG_000_UK 7.8 Page 48 / 66 Audio The modem contains the transparent mode application. The audio interface is standard to connect an equipment like a telephone handset. The echo cancelation (command AT+UMGC) and noise reduction features are also available in order to improve the audio quality in the case of free-hand applications.
PAGE 49
EG_GenPro25e_1055_UG_000_UK 7.8.1 Page 49 / 66 Microphone inputs The microphone inputs are assembled in differential to reduce the noise in common mode and the TDMA noise. They already 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 1.5 kΩ.
