Video Balun Transceiver for Twisted Pair
VB31M
Video Balun Transceiver with pigtail coax and BNC for twisted pair operation with other 
balun transceivers or active receivers. 
 
The VB31M video balun transceiver is a video transmission device that provides a low 
cost means of sending live video over unshielded twisted pair, point-to-point wiring for dis-
tances of up to 750 feet (225 meters) with other passive balun transceivers, up to 1,500 
feet (450 meters) with TR515 single channel and model 51 series hubs, and up to 3,000 
feet (900 meters) with TR560 and model 56 Series hubs. The VB31M is compatible with 
all the "up-the-coax" control systems. A basic system uses (2) video balun transceivers, 
one at each end of a twisted pair of wires. 
 
These units are intended for use over existing in-house telephone wiring, Category wiring 
or other twisted pair cable runs to provide a convenient, cost effective alternative to coax. 
The VB31M is designed to provide superior immunity from noise and interference even 
when running next to line power! The VB31M also provides a unique mounting tab and 
strain relief
