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.
