Determining Cable Length

Check the twisted pair for continuity. Do this by shorting the pair of wires at one end and use an ohm meter to check
the resistance at the other end. Use the chart below to determine the length of your wires for a measured
resistance. Also, use the multimeter to test the line and make sure there is no voltage on it. Testing each line and
recording the length for each camera run can greatly reduce installation time. For distances greater than 1,500 feet
different receiver units are recommended, contact NITEK for specific model numbers.

TR515x8 Card 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 VH3200 - The twisted pair connects to the terminal blocks on the rear of the VH3200.

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 switch for distance - Using the chart below set the 8 position DIP switch on the TR515x8 for the
distance of your twisted pair line plus any coax on each end. The modules are numbered to match the connections.
Do not just try settings to see what works. Knowing the distance and setting the switch will save you time and
provide you with the best possible picture. Note that the 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 setting may vary,
call Nitek Tech Support for help.
