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.

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.
