3.3 Video and Control Cables

3.3.1 Using Coaxial Cable to Transmit Video and Control

Coaxial cable terminated with BNC connectors is the most

common method for transmitting composite video. Bilinx

control data can also be sent over the same cable.

Bilinx is a Bosch 2-way communication protocol that allows

remote control, configuration, and updates over a video coax

cable. Bilinx is available on all VG5 100 and 600 Series

AutoDomes.

VG5 Series AutoDomes feature cable compensation or “Pre-

Comp,” which extends the range of video from the head end.

CAUTION!

600 Series AutoDome: If you are using coaxial cable to transmit

video and data between the AutoDome and the head-end, you

must use the coax cable with ferrite included in the AutoDome

packaging. You must connect the incoming coax cable (from the

head-end) to the jack (female end) on the ferrite cable and

connect the plug end (male connector) of the ferrite cable to

the AutoDome’s coax connector.
