AXIS Q7414 Video Encoder Blade
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.
A half-duplex RS485 interface for controlling auxiliary
equipment such as PTZ devices.
