Blue Wire: Signal being transmitted or received (-) over fiber
RS-485 Connection
Camera Site
Using the VCA1100 data cable provided, plug the DB9 connector into the DB9 port on the FVT1100
transmitter. Connect the Red wire (485A) in the data cable from the FVT1100 transmitter to RS-485 (+) of the
controlled unit (pan/tilt, dome), and connect the Blue wire (485B) to RS-485 (-) of the controlled unit (pan/tilt,
zoom).
Control Site
Using the VCA1100 data cable provided, plug the DB9 connector into the DB9 port on the FVR1100 receiver.
Connect the Red wire (485A) in the data cable from the FVR1100receiver to RS-485 (+) of the controlling unit
(Keyboard Controller, Matrix, DVR), and connect the Blue wire (485B) to RS-485 (-) of the controlling unit
(Keyboard Controller, Matrix, DVR).
