This connector allows the connection yenpro an external DC supply, and provides one general-purpose input and one general-purpose output.

This connector provides 2 general-purpose inputs. It also has 3 general purpose inputs and 1 output. The characteristics of the different GenPro are shown in the Product Differences table. Options and accessories available for the modem GenPro modem are shown in the table below: The modem is now ready.


Refer to chapter 5. The modem should reply with OK. In the case where no communication can be established with the modem: Some examples of AT commands which can be sent to the modem once the communication has been established and verified these commands are explained in detail later in the document: This RESET signal should be considered as a means of re-initialising the modem in cases of emergency only.

The circuit breaker is necessary for security reasons. The circuit breaker is connected to the ground of the lorry, usually connected to the fuse box.

As such, most lorry circuit breakers cut the ground connexion rather than the battery power side as shown in the diagram below: The diagram above shows a recommended connexion, where the modem is connected after the circuit breaker to the ground of the lorry or genpor the fuse box and NOT directly to the earth of the battery Descriptions and non-contractual illustrations in this document are given as an indication only.

Otherwise the modem may be damaged when the lorry is starting and the circuit breaker is closed.

Device Data

In this case the ground of the lorry and the ground of the battery will be connected together via genpr modem as shown in the diagram below: Example of a forbidden electrical connexion risk of damage to the modem The diagram above shows an electrical connexion which may damage the modem because its ground is connected directly to the earth of the battery.

In this example, when the circuit breaker is closed, the current flows via the modem and the electrical circuits in the lorry dash-board for example. The internal circuits of the modem are not designed to withstand the high currents associated with starter motors.

LED flashing once every 2 seconds The modem is powered, the PIN code is active, the modem is recognised by the network and is ready to make or receive a call Idle mode.

To activate the modem echo, enter the command ATE1. When using a communication application to send AT commands to the modem, it is recommended to: For a communication Machine to Machine with the modem, it is recommended to deactivate the modem echo enter the command ATE0 to avoid the CPU receiving redundant responses. When used without the SIM card, this command will simply indicate the closest BTS due to the fact that the modem cannot identify the current subscription.

It is therefore advisable to make this test with the SIM card present. To verify the GSM signal quality, perform the following operations: The response is in the following format: Below 10 the signal is insufficient, the modem cannot grnpro depending on the geographical situation or gfnpro mobility of the vehicle. Above 15 the signal is of a sufficient level. It provides information about the operators, signal strengths and quality, etc.

The table below shows the main responses from the modem: Using a communications application, enter the following AT commands: The user has only 3 attempts to enter the PIN code. Verify the network registration status. The response will be of the following format: Verify the registration status with the aid of the following table: The modem is searching for a network operator.


The modem is GSM attached to a local operator. The modem is GSM attached to an operator in roaming mode. Venpro the modem is not registered, verify the antenna connexion and the receive signal level see chapter 5. Main AT commands used with the modem. FAX Descriptions and non-contractual illustrations in this document are given as an indication only.

If this is not done, then, in certain cases the modem can remain registered on the network.

Before cutting the power in dialog mode no communicationsend the following command to the modem: The modem will return OK and is no longer registered on the network. The radio module is put into standby and the power may then be removed.

There is no particular action to be made to the GPS module before removing the power. This consists of downloading the software into the internal Flash memory via the RS serial link available on the pin Sub HD connector. Please refer to the software update procedure document for a detailed description of this procedure. Returns nothing Check Is the modem correctly powered? Is the serial cable connected at both ends PC and Modem?

Action Ensure that the modem is connected to an external regulated power source 5. Verify the connexion of the serial cable. Is the serial cable correctly cabled Cable the serial cable geenpro to the table in according to the table in chapter chapter 3. Returns nothing or random characters Is the communications terminal correctly configured on the PC? Is there another application using the same port thus creating a conflict?

Is the modem echo deactivated and without message reporting? Ensure that the terminal configuration corresponds to that of the modem. Enter the command ATI. All other responses indicate a dialog with another modem. Verify the COM port used in the communications application. In the case of an error, the response is in the form: Is the modem registered on the network? Is the antenna correctly connected? Verify network registration see chapter 5.

Check the GSM grnpro installation see chapter 8. Ensure that the semi-colon ; been entered immediately after the telephone number in the AT command, for example: Is the selected modulation type supported by the called number? Ensure that the selected modulation type is supported by the called number.

Is the selected modulation type supported by the network?
