6.5 General Questions
Is it possible to use a cable length longer than 1000ft (300m)?
It might be possible to use a cable of up to 1650ft (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?
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 (if it is installed correctly!)
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.
