Ignition Sense
The connections between Pins 14 and 15 on both D-15 connectors should
be made using screened cable. The screen is then connected to the negative
supply pins.
The ignition sense connection between pins 3 and 4 is sometimes necessary
To ensure that the radio switches on when power is applied. When used in a
repeater or rebroadcast configuration there is no control head which would
otherwise indicate this.
No connections are required to the radio RJ45 ports and the red, cross over
cable is not used in this configuration. If required, GPS tracking at the
repeater vehicle is handled by plugging the computer into the RJ45
connector on the TWC radio.
TWC Radio
Rebro Channel Radio
If required, a control head can be fitted to the TWC radio via the
RJ45 port. If the power supply to the rebro channel radio is
switched, then the system only enters repeater mode if this switch
is on. If not then the primary radio functions as normal. The
operator must take care that the TWC radio is actually on the
team working channel before rebroadcast is switched on
however.
If both a control head and forward control GPS tracking of team
members is required then an MA-ASIG accessory board configured
for dual control heads should be fitted. The control head is plugged
into the MA-ASIG board and the tracking computer is connected
via the radio RJ45 port.
