Presentation

Entirely dedicated to geo-localization and embedded data services, the modem GenLoc 31e AOB combines
both GSM/GPRS and GPS functions in the same robust case.
The GPS data can be transmitted by SMS or data GSM/GPRS communication.
This product includes the GPS function 50 channels Hypersense and its sensitivity ensures the GPS data
collection in difficult environmental conditions.
The modem is Quad-Bands 850/900/1800/1900 MHz and GSM/GPRS Class 10.
The GenLoc 31e AOB 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 EG_EGM_CL_xxx_yy of ERCO & GENER).
Autonomous mode (optional): Once configured, the modem is autonomous; it cyclically registers the
positions and transmits them automatically to the client’s application via different services: SMS,
GSM Data, TCP socket GPRS (see EG_EaseLoc_01_CL_xxx_yy 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.
The GenLoc 31e AOB provides TOR inputs/outputs allowing the creation of embedded telematic solutions
with high added value.
This document describes the modem and provides the following information:
- General presentation,
- Functional description,
- Available basic services,
- Installation and use of the modem (first level),
- Trouble shooting,
- Recommended accessories for the use of the modem.

5 Using the modem

5.1 Starting with the modem

5.1.1 Mounting the modem

To mount the modem on a support, use the fixing brackets as described below.
Fixing brackets
- Must be fixed on a flat surface.
- Max. height of the screw head: 2 mm.
The aluminum casing of the modem is connected to the 0V (GND) of the power supply and to the 0V of the RS232 serial link. To avoid any risk of conduction of the ground plane to other equipments,
the modem must be electrically insulated from its mechanical support.

5.1. Installation of the modem

To install the modem, it is recommended to do the following operations with the modem turned off:
- Remove the SIM card cover on the rear side.
- Carefully insert the SIM card into the reader.
Way of insertion of the SIM card
- Push the SIM card until hearing a "clic" that ensures its correct positioning.
- Put the SIM cover back.
- Connect the GSM antenna to the SMA connector.
- Connect the GPS antenna to the SMB connector.
- For the connection to the DTE, connect the V24 link via the 15-pin Sub HD cable.
- Connect the supply cable to the continuous and regulated power source (for an automobile
application, see the paragraph 5.2).
- Connect the supply cable to the modem and turn on the external power supply.
Descriptions and non-contractual illustrations in this document are given as an indication only.
ERCO&GENER reserves the right to make any modifications.
The modem is now ready.
There are different cases depending on the application or library installed inside the
equipment:
- Without library: corresponds to the Boot_Loader.
- With EGM standard library.
- The application ERCO & GENER EaseLoc-01.
- The owner application.

5.1.3 Checking the communication with the modem

5.1.3.1 Without Library
The GenLoc 31e AOB does not contain any library, it will return the menu of the Boot-Loader.
Connect the link RS232 between the DTE (the COM port) and the modem (DCE).
Set the RS232 port of the DTE as follows:
EG_GenLoc31e_AOB_1003_UG_006_UK Page 20 / 64
Bits per second : 115 200 bps,
Data Bits: 8,
Parity: None,
Stop Bits: 1,
▪ Flow control: material.
Use a communication software like HyperTerminal ® of Windows.
Menu by default when there is no library inside the equipment (example of display)
Bootloader V2.27L UE GenLoc 31e AOB (HW0F rev C) 1 - Update application 2 - Erase objects M - GSM direct access A - Advanced E - Exit
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.
