Setup and Installation 

 

4  Setup and Installation 

First ensure all units have been configured for correct operation and signal 

types. See appropriate configuration sections of this manual and the respective 

transmitter manual.  

4.1  Making the Connections 

This section contains figures showing connections with the specific 

Cobra 

R500A / R500-2

 series models. In general, however, the connection and setup 

procedure at both transmitter and receiver ends is as follows: 
At the transmitter end (refer to the transmitter user guide): 

1.  Connect the source video to the 

Cobra 

Series transmitter video input port, 

which is an HD15 connector labeled SOURCE IN. 

2.  If desired, attach a local monitor via the local monitor port to LOCAL 

OUT. 

3.  Make your audio/serial connections via the 1/8” (3.5mm) audio connector 

or DB9 serial connector (transmitter model dependent). 

4.  Connect the CAT 5 cable to the transmitter. 
5.  Apply power on the transmitter. The LED should light and, if there is a local 

monitor attached, a video image should appear on the monitor’s screen. 

At the receiver end: 

1.  Connect the VIDEO OUT HD15 connector to the display unit and attach 

any audio cabling. 

2.  Connect a 1/8” (3.5mm) audio or serial cable to the AUDIO or SERIAL 

OUT connection (model dependent). 

3.  Connect the CAT 5 cable to the UTP INPUT connection. 
4.  Apply power. The LED should light and video should appear on the 

display(make sure display is powered ON). 

5.  Adjust video levels. 

With regard to connecting the cables: 

 

We recommend mounting and connecting all cabling to the 

Cobra R500A 

/ R500-2

 components before applying power. 

 

Be sure that the CAT 5 cable you intend to use has been tested to comply 

with the T568B wiring specification (see Appendix A).
