Presentation
Entirely dedicated to geo-localization and embedded data services, the modem GenLoc 41e 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 41e 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 ERCOGENER).
▪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 ERCOGENER).
▪Specific development mode: the EGM development tool allows to develop a personalized embedded
application. For more information concerning the tools and the training, please contact our sales
department.
The GenLoc 41e provides digital 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.
- Options, contact us.

ERCOGENER cannot be held responsible for:
- The problems due to an inappropriate use of the GenLoc 41e.
- The problems due to a wrong configuration
- The problems due to a wrong use of an embedded software application developed or
supplied by a third party.
- Dysfunctions due to the absence or a bad coverage or termination of the GSM, GPRS and
GPS networks.
- The dysfunctions if the product is used for the watching of physical persons where human
life is engaged.
ERCOGENER reserves the right to modify the functions of its products "GenLoc 41e" and
"EaseLoc" without previous notice.
- In order to avoid any risk of electrocution, do not open the casing.
- For any functioning, the casing must be closed.
- No internal part can be repaired by the user. The GenLoc 41e must be returned to the factory for any repair
the RMA request (Return Material Authorization).
- The GenLoc 41e must be placed in a normally ventilated area, out of sources of heat.
- In order to guarantee the electromagnetic compatibility, the length of the serial cable, the supply cable and
the inputs/outputs cable must not exceed 3 meters.
- The GenLoc 41e must not be connected directly to the mains supply; a voltage adapter must be used.
This marking on the product, accessories, packaging or literature indicates that the product
and its electronic accessories (e.g. cable etc.) should not be disposed of with other household
waste.

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.
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.
Accessories supplied
- Fixing brackets (x2)
- 4-wire Micro FIT cables (Power supply, Input and Output)
- 2-wire Micro FIT cables (2 Inputs)
Options / Accessories *
- Back-up battery
- Management of battery charge
- Command ON/OFF of external supply by soft
- Command ON/OFF of external supply by DTR
- Power down of the RS232 by soft
- Backup Real Time Clock (if option backup battery)
- Bus I2C (instead of signals DSR and RTS)
- 3-axis accelerometer
- Analog input (instead of opto-coupled input E2)
- Analog input (instead of output SPKN)
- Gen 10400 : Adapter RS232 / Digital Tachograph
- GenBlue 15e : Adapter Bluetooth® / RS232 auto-supplied
- 1 port ONE_WIRE
- Software development kit : cdrom SDK EGM
- Accessories: Antennas, cables, power supply... (consult our website)
- Must be fixed on a flat surface.
- Max. height of the screw head : 2 mm.

5.1.2 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 back side.
- Carefully insert the SIM card into the reader.
- Push the SIM card until hearing a "clic" that ensures its correct positioning.
- Put the SIM cover back.
- Connect the GSM antenna to the connector FAKRA-D.
- Connect the GPS antenna to the connector FAKRA-C.
- 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.
The modem is now ready.
There are different cases depending on the application installed inside the equipment:
- Without library: corresponds to the Bootloader.
- With EGM standard library
- The application ERCOGENER EaseLoc-Vx.
- The owner application.
We may obtain different display. See the following paragraph.
