Axis Rack Mounted Video Server Solution
Description
This pin can be used to power auxiliary equipment, max 100mA
Connect to GND to activate or leave floating (or unconnected) to
deactivate.
With a maximum load of 100mA and maximum voltage of 24V DC, this
output has an open-collector NPN transistor with the emitter connected to
pin 2 (GND). If it is to be used with an external relay, a diode must be
connected in parallel with the load for protection against any voltage
transients.
A half-duplex RS-485 interface for controlling auxiliary equipment,
e g. PTZ devices.
