expose this product to rain or moisture.

Installation

The VH3200 UTP modular hub is designed to operate with a mix of Nitek UTP video cards either active or passive.

If you are using pre-existing wire or are not sure of the distance you are going the following wire tests are highly

recommended.

Checking the Wire

1. Loop Resistance - Short one end and check the resistance between the wires at the other end. This will give

you the loop resistance and wire distance (See Chart).

2. Open Loop - Open the shorted end and check for infinity at the other end.

3. Short or Leakage to Ground - With both ends open check each wire to earth ground. The reading should be

infinity or megohms.

4. No Voltage on Wires - With both wires open check for DC or AC, other than stray AC, on the wires.

For distances greater than 3,000 feet an amplified transmit source may be needed.

Connecting the Hub

If using the unit as a receiver, connect the twisted pair from the camera end to the screw terminals on the back,

make sure of the polarity of the connection. If the wires are reversed the video will be unviewable on the monitor.

Connect the matching BNC to your video system as needed.

If using the unit as a transmitter, connect your video source to the BNC and connect the twisted pairs leading to

your monitor end to the matching screw terminals. Note the polarity of your connections.
