4 OPERATION

4.1 Introduction

This section covers the simple operation of the modems. It provides the relevant information for the
user to get the modem up and running.

A +9V to +28VDC power supply will be required, together with a Windows 95 PC, installed with Hyper
Terminal, or similar package, a CA8360 power cable, a CA8401 antenna and a CA8361 PC serial
cable.

4.2 Network Connection

It is necessary to obtain a SIM from your chosen Network Provider. This SIM must be suitable for
Data service.

All information needed to connect you to the network and to initiate billing for your calls is stored in the
gold-plated area of the SIM card, along with the names, numbers and messages you have entered
into the phone book, or received.

To prevent either, the loss of information or corruption of information, avoid touching the gold area and
do not place the SIM near electrical or magnetic fields.

A damaged SIM will not allow you to access the GSM network.

4.2.1 Inserting the SIM card

The SIM card will probably be supplied in a cardholder and will need to be carefully pressed free,
before fitting.

The modem must not be powered. If the 25 way D-type connector is removed, this ensures that this is
the case. The modem should be turned upside down and the two small countersunk screws removed
to expose the SIM card area.

Figure 4-1 - Location of SIM card

Issue 1.0 ME 820047
03/00 Page 7

MM6854/64 Dual Band GSM Data Modem

Care should be taken to ensure that the card is correctly fitted and is held in place. This is
accomplished by fitting the card (with the gold area facing downwards) underneath the two lugs and

sliding the metal holder over the top of the card to secure it.

then

Holder

The lid can now be attached and held in place with the two screws.

Figure 4-2 - Securing of SIM card

4.3 Turning on the modem

To turn on the modem, connect power between pin 16 (+9V to +28VDC) and pin 17 (GND) of the D25
connector. Alternatively, fit accessory cable CA8360 and connect power between the red and black
leads. Connect a suitable antenna; the Maxon CA8401 is ideal.

Note

: It is important that the antenna ground is not connected to the modem ground. This will not
happen where through glass antennas are used. Antennas, which are through chassis mounting and
connect to the vehicle chassis should not be used. Failure to observe this may result in damage to the
unit and will invalidate the warranty.

Pin 15 of the D25 connector has to be pulled LOW in order to turn on the modem. Alternatively, fit
accessory cable CA8360 and connect the green lead to GND.

Provided that the SIM card is unlocked, the modem will make an automatic search for your home
network or another suitable network operator in your location. The modem will initially flash RED as it
establishes a network connection (within seconds) and then flash GREEN.

Note

: To prevent unauthorised use, the SIM can be protected by a PIN code (See Section 5.1.40).
Each time the modem is switched on the PIN code must be entered. If you enter the wrong code,
three times in succession, your SIM will be barred from the network and the modem will require a PUK
code.

4.4 V.24 Interface

The modem is set to communicate with a baud rate, which is set as default to 19200 baud. The
modem does not support autobaud and therefore it is important that any equipment, which
communicates with the modem, is set to 19200 baud.

4.5 Set up the appropriate software

Information is provided in Section 8.2 for setting up Hyper Terminal and TAPI devices for use with the
modems.

4.6 Confirming Operation

On Hyper Terminal, type ATD <Telephone number you want to ring> and press Carriage Return.
The telephone will ring. The answer tone will be similar to the one, which you would receive, with a

fax machine.
