Remote Unit Installation
Setting the Cable Length DIP Switches
If your application uses CATx cable less than 25m in length, you can continue
to the next section.
Mini Extender Remote Units incorporate video equalization circuitry, allowing
you to compensate for the loss in image quality that occurs when video signals
are transmitted along CATx cables. At the factory, Remote Units are configured
to optimize the video signals for Interconnect cables up to 25m in length.
If you intend to use cables of 25-50m in length:
1. Locate the DIP switches on the underside of the Remote Unit. DIP switch 1
is used for video channel 1, DIP switch 2 for video channel 2.
2. Set the DIP Switches as follows:
Interconnect Cable Length
(m)
DIP Switch Position
5 – 25 OFF (default)
25 – 50 ON
If you are carrying out a test placement prior to final installation, set the DIP
switch to the position appropriate to the test cable’s length. When your tests are
complete, set the DIP switch to the position appropriate for the CATx cable
length used in the full installation.
Technical Note: The video compensation does not adjust skew. Although skew
(color separation) can be an issue on some CATx cables, it would not normally
be observed on cables <50m. Even so, we still recommend the use of low skew
cables with USB Mini Extenders. You can test for skew by viewing the online test
card at: http://testcard.kvmextender.info
