General Purpose I/O
Analog and Digital Input lines
The SmartCAM™ similarly provides one automotive input line (0-32V) through its enhanced model in
addition to the ignition line. The input line can be read as digital (state 0 or 1) or analog (voltage level)
lines.
Digital Input
IGN (automotive voltage state) is for monitoring the ignition switch signal. The other input line can be used
for any purpose, like sensing door opening, sensing bus amber lights, etc.
The IGN line powers on the device from a shutdown state. For proper power
management, the input should be connected to the vehicle’s ignition switch.
