4.8 Cascade query code
The CPU Switch Smart SUN-MAC-PCs use a special ‘query code’ to detect whether
or not they are connected to another CPU Switch Smart SUN-MAC-PC. By default
your CPU Switch Smart SUN-MAC-PC uses query code AD. CPU Switch Junior
(another range of keyboard / mouse / video switches from LINDY Electronics) units
with firmware versions less than 1.09 used query code EF. This was found to conflict
with a small number of other (rare) devices that used the same query code so an
alternative query code was provided to ensure compatibility. Either query code may
be used but you should make sure that all cascaded CPU Switch Smart SUN-MAC-
PC and CPU Switch Junior units are set to use the same query code. If any of the
cascaded CPU Switch Junior have firmware versions less than 1.09 then the
cascade query code for all the CPU Switch Smart SUN-MAC-PCs and CPU Switch
Junior should be set to EF.
L7 – Cascade query code = AD (default)
L8 – Cascade query code = EF
4.9 Resolving slow mouse problems
Due to certain technical reasons some systems running particular combinations of
operating system and mouse drivers are sensitive to small timing changes relating to
mouse communications. The introduction of a switch like the CPU Switch Smart
inevitably causes some timing changes and in rare cases interactions have been
observed that causes the mouse to run very slowly. Certain HP Vectra computers
running later versions of Windows NT with Logitech mouse drivers and Logitech
mice have been observed to exhibit such interactions with older switches. One
solution to this problem is to change the mouse driver.
The CPU Switch Smart SUN-MAC-PC is a high performance device that is carefully
engineered to minimise such interactions and should not exhibit this characteristic.
Nevertheless such interactions are unpredictable and so the CPU Switch Smart is
