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.
