SERVSWITCH™ BRAND CAT5 KVM/SERIAL/AUDIO EXTENDER
Can the Extender be used with RGB video?
As long as the video has sync on green (the composite sync signal superimposed on
the green color signal), there should be no problem.
Which cable type is better: UTP (unshielded twisted pair) or STP (shielded twisted pair)?
In electrically quiet environments, UTP cable will give the best quality video over
long distances because it has less capacitance per unit length. However, STP is
usually better in electrically noisy environments, because it resists interference
more strongly.
When using UTP, what’s the best way to make sure that the system does not suffer from any
interference?
The Extender is designed to withstand high levels of interference while driving
signals over long stretches of UTP. To further reduce the potential for
interference, consider taking these actions:
a) Make sure that the Extender’s Remote Unit, the remote monitor or KVM
switch, and the local CPU or KVM switch are all connected to the same utility-
power (mains) phase.
b) Make sure that the AC voltage across the utility-power (mains) grounds (at
both the local PC and remote monitor) is less than 2V.
c) Use a “clean earth” or “clean grounding” system (if your site has one
installed).
d) Route the interconnection cable away from generators, motors, compressors,
fluorescent lights, and other cables.
e) Try STP cable if you think noise could be a problem.
This interconnect cable is exactly like the cable I use on my LAN. Can I connect the Extender
to my network?
Absolutely not. Regardless of the cable similarities, the data signals and voltages
used by the Extender are totally different from those used by Ethernet and other
types of networks. Connecting the Extender to a LAN hub, switch, repeater, or
other network device, or exposing it to the signal levels present on network data
lines, is a sure way to blow out the Extender, and could damage other devices
attached to the Extender as well.
Can I rackmount the Extender?
Yes, using Rackmount Kits that are available separately. See
Appendix B
