SERVICE SWITCH USAGE GUIDE

Gefen CAT5 HD products (Sender and Receiver) both contain a pair of service

switches (also called dip switches) located underneath the unit. These service

switches are used to select from sets of conﬁ gurations that will equalize the signal to

best match the conditions in your setup. For the CAT5•7500HD, there are 1 set of

switches for each monitor under both the Sender and Receiver units. The switches are

hidden beneath black stickers. Each bank of dip switches have 4 switches. Switches 3

and 4 are not used. (*Note: Adjustments should be done with sources and display on.)

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. (See page 9 for details)
