RACKMOUNT SERVSWITCH™ BRAND CAT5 KVM EXTENDER LOCAL HUBS
8.2 General Questions About the Extender
Is it possible to use an interconnection cable longer than 300 meters (985 feet)?
With the full-size (non-Micro) Remotes, the Rackmount Extender will produce
acceptable results with SVGA resolutions at the maximum cable length of 300 m
(985 ft.). Therefore, it
might be possible for you to run as far as 500 m (1640 ft.) at
the standard VGA resolution, 640 x 480. However, we do not recommend doing
this and
cannot
guarantee that it will work.
Can the Rackmount Extender be used between buildings?
No. Ground loops could destroy the Rackmount Extender and attached
equipment.
Can I hot-swap interconnect cables in order to access different CPUs from different remote user
stations?
Because the Rackmount Extender performs full keyboard and mouse emulation, it
is possible (though we do
not recommend it) to swap or switch the local-remote
interconnections to create, in effect, a KVM matrix-switch system. You would just
have to remember to always reset the active Remote (see
Section 7.3.1 ) after each
such swap or switch.
Is the Rackmount Extender VESA DDC compatible?
No. It cannot carry the special DDC data lines.
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.
