Wiring Ignition Signal
To have ignition power control for in-vehicle usage, you need to supply IGN
signal to the system. The IGN input is located on the 3-pin pluggable terminal
block (shared with DC power input). For in-vehicle ignition control wiring, please
do the following:
1. Connect car B line (12V for sedan, 24V for bus/ truck) to V+.
2. Connect car Battery -/ GND line to GND.
3. Connect ACC line to IGN.
WARNING
Please make sure your DC power source and IGN signal share the same
ground.
IGN input accepts 8~35VDC. Supplying a voltage higher than 35VDC may
damage the system.
