Installation
Step 1)
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 loop
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, also, check for a very high
resistance to ground and an open when the far end of the wires is
opened. For distances greater than 12,000 feet, there are several
other systems available, contact your local Distributor or NITEK
Technical Department for assistance.
Step 2)
Check the video input at the transmitter unit to make sure
you have video present. Connect the twisted pair to the terminals
marked “VIDEO +” and “-”. There is also an “Earth Ground”
terminal, this connection is required for proper surge protection. If
the “Earth Ground” is not connected the unit will be grounded
through the coax shield. Set the DIP switches on the transmitter
using the following table.
