42 CATx KVM Extender Range
General Questions
Is it possible to use a cable longer than 300m?
It might be possible to use a cable of up to 500m at lower resolutions.
However, we do not recommend this and cannot guarantee that it will
work.
Can the extender be daisy chained?
In certain circumstances, it is possible to cascade extenders, though we
do not recommend doing so. Careful consideration needs to be given to
extender setup, and the electrical environment. If you plan to cascade
extenders, please contact Technical Support.
Which interconnection cable is best?
The extender will operate with either shielded (STP/FTP) or unshielded
(UTP) CATx cable. However, correctly installed shielded cable is
preferred, especially in electrically noisy environments, because it
resists interference more strongly, limits ground potential differences,
and reduces emissions. To benefit from shielded cable the shield
connection must be maintained from end to end through any intervening
patch cables, panels and RJ45 connectors.
Please note that shielded cable is advised in order to maintain
regulatory EMC compliance.
Can the extender system be used between buildings?
No. Ground loops could damage the extender system and attached
equipment.
Can multiple Local/Remote Units be used by swapping the interconnection
cable?
Local Units provide full keyboard and mouse emulation, so it is possible
to swap or switch the local-remote interconnection to create a KVM
matrix-switch system. Sometimes you may need to reset the keyboard
and mouse (by entering the appropriate command) after a swap or
switch. Please call Technical Support before deploying such a system.
Can the extender be connected into our network?
Absolutely not. Regardless of the cable similarities, the data signals and
voltages used by the extender are 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 may damage the extender and other
devices.
