Remote Unit Configuration & Operation

Adjusting Video 

PS/2 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.

 

Ensure that you have installed and powered up the system according to the 
instructions in Section 3. 

2.

 

Enter Command Mode by pressing the following key combination on the 
Remote console keyboard: 

<Left Control> + <Left Shift> + <F10> 

3.

 

By default, both channels are selected for adjustment and this is indicated 
by slow flashing of the keyboard status LEDs (Num Lock, Caps Lock, 
Scroll Lock). If you want to select a single channel press the corresponding 
numbered key: 

Video channel 

Command 

Keyboard Status LED action 

Channel 1 

<1> 

Single flashes 

Channel 2 

<2> 

Double flashes 

Both channels 

<0>

 (default) 

Slow single flashes 

 

4.

 

Press the following key combination to change the video equalization 
setting: 

<Left Control> + <E> 

Note: This command toggles the video equalization setting; repeat the 
procedure to revert to the original setting for a shorter interconnection cable 
length (<25m). 

5.

 

If you are using one or more flat panel monitors in the Remote console, 
carry out auto-adjustment as described in the monitor’s 
documentation. Sometimes manual adjust of clock and/or phase is also 
required for optimum results and minimization of jitter.

 

Technical Note:

 This video compensation does not correct color 

separation (skew). Although skew 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 PS/2 Mini Extenders. You can 
check whether skew is a problem in your system by viewing the test card
