REMOTE UNIT CONFIGURATION & OPERATION

Skew only tends to be a problem at high screen resolutions with long interconnect cables. We recommend the use of low skew CAT5/5e cable for all applications. Please contact Technical Support for more information.

With some cables, video performance may be improved by using a crossover patch cable at each end, an alternative RJ45 pin-out or an external skew correction device (see Appendix C: Advanced Cabling Issues (Skew), page 45).

The alternative ServSwitch™ Brand CATx KVM Extender range has been specifically designed for the extension of high screen resolutions (1600x1200) over long CATx cables (300m). ServSwitch™ Brand CATx KVM Extenders have fully integrated skew compensation and independent control of low frequency (LF) and high frequency (HF) cable equalization.

4.2Video Adjustments

Remote Units feature a number of correction tools to simplify video optimization. This procedure is straightforward and only needs to be carried out once.

Please note that cable equalization cannot be exact – the remote image will never be as sharp as the original. The KVM Extender’s equalization system produces good results for short to medium length cables (<150m).

Adjusting Video

Use the following step-by-step procedure to optimize the video image on the remote console:

1.If possible, view the online test card at:

ftp://ftp.blackbox.com/connectivity/ServSwitch/

This is an image (see Figure 9) created and used by the manufacturer for video optimization purposes. It is particularly useful for observing skew. If you are unable to view the test card, display some text in a large font on a white background.

You should also open up other application windows to check the clarity of text in tool bars and icons on the desktop.

2.Turn the Brightness and Focus controls on the Remote Unit fully anti-clockwise. The image quality may be poor at this point.

3.Use the Focus control to adjust video equalization. If the video signal is under- compensated, you will notice black smearing on the right-hand edge of large horizontal objects such as title bars. If it is overcompensated, horizontal edges may become bright and too sharp. Rotate the Focus control clockwise until these effects disappear. The compensation is now adjusted correctly for the length of cable.
