Operation
Power and activity indicators
On the front panel of both modules
are small recessed indicators which
provide conrmation of power and
activity, as follows:
• Constant red - power applied, no
communication activity.
• Flickering red - power applied,
mouse or keyboard activity
occuring.
• Slow ashing red - module is in
ash upgrade mode.
Note: Both modules contain internal
automatic cut-out fuses to protect
against power surges. To reset, remove
power (or, for the LOCAL module,
the multi-cable connection) from the
module for one second and then
reconnect.
General use
In use, the X2 Dual Access modules should be almost transparent - the system
and its peripherals should operate almost exactly as normal, the only difference
being that they are duplicated (see ‘User arbitration’ below) and one set is now
up to 300 metres away.
User arbitration and keyboard indicators
During operation, both of the connected video monitors continuously receive
the output from the host system. Control of the host system is arbitrated by
the X2 Dual Access modules on a rst come, rst served basis. In the idle state,
control is available to both users and their keyboard indicators both show the
current Num Lock, etc. conditions of the host system.
At the moment that a key is
pressed or a mouse is moved,
the keyboard and mouse of
the other user are temporarily
locked-out (the video images
remain). The keyboard
indicators of the locked-out
user then begin to ash to
conrm their status
ð
After two seconds of
inactivity from the user
currently in control, the modules return to their idle condition and re-instate the
keyboard indicators of the locked-out user.
Visible image shadows
In some installations, you may see some ‘shadows’ to the right of high contrast
screen characters. This can be caused by an incorrectly selected sharpness setting
and it may be necessary to make adjustments to correct this. Please see ‘Image
controls - sharpness and brightness’ in the ‘Special conguration’ section.
