8
Channel 6, Configurable I/O 1
9
Channel 1, Configurable I/O 2
10
Channel 2, Configurable I/O 2
Digital input - Connect to GND to activate,
or leave floating (or unconnected) to
deactivate.
Digital output - Uses an open drain NFET
transistor with the source connected to
GND. If used with an external relay, a diode
must be connected in parallel with the load,
for protection against voltage transients.
Min input = – 40 V DC
Max input = + 40 V DC
Max load = 100mA
Max voltage = + 40 V DC

RS485B
A half-duplex RS485 interface for controlling auxiliary equipment such as PTZ
devices.
