WARNING!
Cable compensation (Pre-Comp) does not extend the range of Bilinx control. Pre-Comp is not
available with VG5 700 Series AutoDomes.
Using UTP to Transmit Video and Control
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.
VG5 Series AutoDomes feature cable compensation or “Pre-Comp,” which extends the normal
range of control from the head end.
WARNING!
Do not connect the RJ45 connector unless using UTP video.
