GND Pin 1 Ground Description
12V Auxiliary DC Power
(not to power this
camera)
Pin 2 Electrically
connected in
parallel with the
connector for the
power supply, this
pin provides an
auxiliary connector
for main power to
the unit. This pin
can also be used to
power auxiliary
equipment with a
maximum current of
100mA.
Voltage: 12V DC,
Max: 1.2W
DI1(Digital Input) Pin 3 Connect to GND to
activate, or leave
floating (or
unconnected) to
deactivate.
Must not be exposed
to voltages greater
than 30V DC
DI2 (Digital Input) Pin 4 Connect to GND to
activate, or leave
floating (or
unconnected) to
deactivate.
Must not be exposed
to voltages greater
than 30V DC
DO(Digital Output) Pin 5 Uses an open-
collector NPN
transistor with the
emitter connected
to the GND pin. If
used with an
external relay, a
diode must be
connected in
parallel with the
load, for protection
against voltage
transients.
Max load = <100mA
Max voltage = 24V DC
(to the transistor)
