Remote Unit Configuration & Operation
25
Private Mode
On dual access systems, a user at one console can lock out the other console by
triggering a ‘Private Mode’ function. This prevents the other console from
being used even if the two-second inactivity timeout period expires.
To indicate that the Private Mode session is active, the extender system:
•
Slowly flashes the Scroll Lock LED on the user’s keyboard.
•
Illuminates all three LEDs on the other console’s keyboard.
•
Locks the other console’s keyboard and mouse.
•
Displays a blank image on the other console’s monitor. If you want the
other console monitor(s) to remain active during Private Mode sessions, use
the
Toggle Blanking State
command.
To cancel the Private Mode, enter Command Mode again and press
<Scroll
Lock>
. This command also closes Command Mode.
DDC Emulation
Modern graphics cards use VESA DDC (Display Data Channel) to identify the
capabilities of connected monitors. Some cards will not operate correctly unless
they communicate with a DDC-enabled monitor.
By default, the Local Unit emulates a universal monitor (on both channels) and
reports that it is capable of all standard screen resolutions and refresh rates. This
ensures that the vast majority of graphics cards and monitors should operate
correctly with the extender system.
The DDC emulation can be optionally disabled but this would only be required
in special applications.
It is also possible that the default DDC emulation may not report a non-standard
graphics mode, for example, if an HDTV monitor is connected. In this case, the
Local unit’s DDC emulation data could be flash-upgraded with a custom DDC
table. Please contact technical support to discuss your application.
Alternatively, the DDC from the remote monitor(s) may be read and stored in
the Local Unit using the Transfer DDC command (see page 26).
Always reboot Windows after adjusting a DDC parameter.
