OPERATION NOTES 

 

READ THESE NOTES BEFORE INSTALLING OR OPERATING THE HDMIEXTEND 

  The HDMIEXTEND transmitter and receiver is housed in a metal box for better RF shielding. 

  The CAT-5 cable should not exceed 200 feet. 

  If you do not need DDC or HDCP data you can use a single CAT-5 cable for the video only. 

The DDC will not be connected. (For further information, see our Technology Terminology 
section) If HDCP is required, both CAT-5 cables must be used between the transmitter and 
receiver units. 

 

CAT6 cable is suitable for high resolutions at 50 meters.

 

 

SERVICE SWITCH USAGE GUIDE 

 

The transmitter and receiver of the HDMIEXTEND products both contain a set of service switches 
(also called dip switches) located underneath each unit. Peeling back the silver sticker will reveal the 
service switch bay. These service switches are used to boost and equalize the signal to best match 
the conditions in your setup.  
 
(*Note: Adjustments should be done with sources and display on. Switches 3 and 4 are not used.)

Adjustment Guidelines: 
 
1) Strong boost should not be used on stranded cables. Strong boosting will cause pixels or no 
picture on these cables. 
 
2) Using the wrong settings will not damage the units; it will either produce no image or a noisy 
image. 
 
3) To eliminate the possibility of cross talk and interference, cables must be terminated with 568B 
scheduling.
