The radio allows for different installation configurations for vehicles with
respect to ignition signal and standby current. For special configurations for
desktop and remote site installations, refer to the service manual.
The installation configurations described below are based on the following
hardware link configuration:
hardware link 1 (+13.8V battery power sense): fitted
hardware link 2 (ignition sense): fitted
For more information on the hardware links, refer to the service manual.
The radio's power cable must always be connected directly to the power
source (battery).
Important
Although it is possible to connect the radio in line with the
vehicle ignition, this installation method is not
recommended, as it may draw too much current, resulting
in damage to the vehicle wiring and steering column or
ignition switch. This may also cause the supply voltage of
the radio to drop below the specified level.
The radio can always be turned on and off using the on/off button,
independent of the ignition signal.
Connect the power cable directly to the power source as described in
"Connecting the Power Cable" on page
Note
If hardware link 1 is fitted and the ignition signal is not used, the
standby current is 28mA. To reduce the standby current to 1mA:
– remove hardware link 1, or
– connect pin 4 (AUX_GPIO3) to pin 15 (GND) of the auxiliary
connector, and program the AUX_GPIO3 line as described below.
Connect the power cable directly to the power source as described in
"Connecting the Power Cable" on page
Connect pin 4 (AUX_GPIO3) of the auxiliary connector to the ignition
signal as described in "Connecting to the Auxiliary Connector" on page
Note
The AUX_GPI3 line must be programmed to 'Power Sense
(Ignition)' and active to 'High'. For more information, refer to the
online help of the application software.
