4. Operation
4.1 Power and activity indicators
On the front panel of both modules are small recessed
indicators which provide confirmation of power and activity,
as follows:
•
Constant red – power applied no communication
activity.
•
Flickering red - power applied, mouse or keyboard
activity occurring.
•
Slow flashing red – module is in flash 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 keyboard connection) from the module for one second and then
reconnect.
General Use
In use, the Extender C5 modules should be transparent - the system and its peripherals should operate exactly
as normal, the only difference being that they are now up to 300 metres apart.
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 configuration' section.
4.2 Locking and unlocking the system
In situations where the computer system (and the LOCAL module) can be locked away the Extender C5 set
offers a viable security system to deter unauthorised use. Once a password has been set, a simple key
sequence allows the system to be quickly and securely detached from its peripherals. Only the correct password
will reconnect the remote and local modules.
To lock the system
1
First set a password. For further details, please refer to
section 5.4 'Password setting.'
2
Simultaneously press the currently configured hotkeys
(by default, <CTRL> and <SHIFT> along with <L>.
The screen will go blank and the three keyboard indicators will
begin alternately flashing between the 'Num Lock' and 'Scroll
Lock', and 'Caps Lock'. This sequence indicates that a password
is required.
