8.3.10 Emergency
If an emergency switch is assigned, asserting the input causes the radio to go into emergency
mode.
Emergency switch assigned to pin 9 is a special case. In addition to normal emergency mode,
asserting the input when the radio is turned off will invoke Emergency with Wake Up. This causes
the radio to power up and immediately enter Emergency mode.
8.3.11 Ignition
Ignition sense is programmable per radio. Connecting the vehicle ignition to this line causes the
radio to turn on automatically when the ignition is turned on, and turn the radio off when the ignition
is turned off. This feature is particularly useful where the radio must always be on when the vehicle
is in use, for example, a fire engine.
Benefits
The radio turns on automatically when the vehicle is started.

Data Transmissions

Mobile data systems are increasing in popularity. The GM300 Series mobiles have been designed
with this is mind. They have:
flat transmit and receive audio available on the accessory connector;


special programmable digital lines on the accessory connector;


the ability to connect an internal or external data modem to the radio.


An external data modem can be connected to the mobile via the rear accessory connector.
An internal data modem can be fitted neatly inside the DataPro accessory. The mobile's control
head is put into the remote mount configuration and then the DataPro is connected to the front of
the transceiver. The audio and digital signals that are normally routed via the rear accessory
connector are taken out via 2 D-type connectors on the front of the box. This gives easy connection
with standard connectors to other external devices, such as computers.
Motorola has selected Application Partners who have specially designed modems to fit inside the
GM300 Series mobiles. Several different signalling formats and speeds of modem are available to
meet the many different application requirements. Most have RS232 signalling via the D-type
connectors.
