6.4 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)
CAT5/5e 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.
