Installation
VH456 w/Passive (Balun) Transmitter
1) Connect Balun to Camera - Using the installation
manual provided with the balun connect it to the
video source, usually a video camera. If you have a
UTP ready camera connect the twisted pair directly
to the camera video out.
2) Connect Twisted Pair to VH456 - The twisted pair
can be connected to either the push-in terminal
blocks or the RJ45 jack.
3) Connect Video Out to your System - Using standard
coax cable connect from the video out BNC to your
system as needed for viewing.
4) Set DIP Switches for Distance - Using the chart
below set the 8 position DIP switches on the VH451
for the distance of your tested pair line plus any coax
on each end. The modules are numbered to match
the connections. Knowing the distance and setting
the switch will save you time and provide you with
the best possible picture. Settings listed are for
standard communication cable. Should you be using
wire gages less than 22 awg or shielded wire with
less than 10 pair your settings may vary. Call Nitek
Tech Support for help.
5) Connect the Power Supply - Connect a 12/24 VAC/
VDC power supply to the power input terminals.
