Video and Control Cables

Coaxial Cable
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 AutoDomes, except Ethernet models,
using the standard communications module.
AutoDome Series 300 and 500i feature cable compensation or "Pre-Comp," which extends the
range of video from the head end.

WARNING!
Cable compensation (Pre-Comp) does not extend the range of Bilinx control. Pre-Comp is not
available to AutoDomes with an IP module.
UTP
Unshielded twisted pair (UTP) cable terminated with RJ45 male connectors are used to
transmit composite video using pins 1(+) and 2(-). Typically, a Coax to UTP cable converter is
required at the head-end of the system.
Bilinx control data can also be sent over the same two video wires (1 & 2). Bilinx is a Bosch 2-
way communication protocol that allows remote control, configuration and updates over a
passive UTP cable.
AutoDome Series 300 and 500 feature cable compensation or "Pre-Comp," which extends the
normal range of control from the head end.
