Remove the front panel of the receiver by pulling the knobs 

toward you. Inside locate the receiver unit to match the camera you are 
working on. Set the DIP switches for your camera distance as listed 
below. Use the setting closest to your actual cable length. If you have 
no video or a streak through your video your wire pair may be reversed. 
When finished replace the front panel and lock it in place by pushing 
the knobs in. 
 

After having adjusted each receiver, connect them to the rest of 

your video system. Each video channel provides 2 outputs. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

The settings listed are for normal conditions. Other settings are 

possible. For sharpness adjust switches 7 and 8. For gain adjust 5 and 
6. Switches 1 and 2 or 3 and 4 must be operated in pairs according to 
distance. 
 

Step 5)

 

 

There is also an “Earth Ground” terminal on the rear of the 

receiver, this connection provides improved surge protection, it is not 
required for operation. If the “Earth Ground” is not connected the unit 
will be grounded through the coax shield.
