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 100 and 600 Series AutoDomes feature cable
compensation or “Pre-Comp,” which extends the normal range
of control from the head end.
The following figure illustrates the connections necessary to
transmit video and control over a UTP cable.
