Introduction

Twisted Sender has been designed by Nitek to transmit video signals over a point to point pair of wires. The wire
should be free of voltage or other outside signals. Twisted Sender can turn your in-house phone lines, leased
telephone lines or cable runs into pathways for video signals. Twisted Sender is ideal for shopping malls, parking
garages, remote gates, large factories, airports or any number of places where you need to connect video
equipment.

Installation

1) Check the twisted pair for continuity. Do this by shorting the pair of wires at one end and using an ohm
meter to check the resistance at the other end. The chart below will give you the length of your wires for a
measured resistance. Use a multimeter to make sure there is no voltage on the line.
For distances greater than 1,500 feet, there are several other systems available. Contact your local
Distributor or Nitek Technical Department for assistance.

The TR515x4 receiver can be used with any standard twisted pair video camera or Balun type transceiver device.
Steps 2 and 3 refer to the Nitek VB37 Balun.

Installation (cont’d)

2) Check the video input at the transmitter unit to make sure you have video present. Connect the
video to the BNC jack of the VB37 transmitter unit. The transmitter is a passive device called a
Balun and requires no power.

3) Connect the twisted pair to the screw terminals and note the polarity of this connection. If the
wires are reversed, when you connect the receiver the video will not be viewable on the monitor.

4) Plug the receiver card into the Nitek card cage and connect a test monitor to the desired output
BNC connector (1, 2, 3 or 4).

5) Locate the twisted pair input terminals (marked “+” and “-”) which match the video output BNC
selected. Connect the twisted pair, note the polarity of the connection. If the wires are reversed the
video will not be viewable, this will not damage the unit. Reverse the wires and the video will be
correct.

6) DIP switches are provided so that the unit can be adjusted for the best picture. The following
settings are factory recommended for normal conditions. For added sharpness adjust switches 7
and 8. For more gain adjust switches 5 and 6. Switches 1, 2 and 3, 4 must be operated in pairs.

Troubleshooting

Problem Video inverted or rolling and unstable.

Fix/Cause • Reverse the wires of the twisted pair at either the transmitter or receiver.

Problem No video out at the receiver.
Fix/Cause • Check to make sure that there is video in at the transmit end.

• Make sure that the pair of wires you are using is not open or shorted between the
transmit and receive points.

Problem Ghost image at the receiver.
Fix/Cause • Bridge tap or “T” tap on the twisted pair video line. Remove tap.
