22 CATx KVM Extender Local Hubs
Local Console Commands
After pressing the initial ‘hot’ key on the local keyboard, you can issue a
number of commands by pressing additional keys. These commands allow you
to start a private mode session on the local console or to reset the keyboard and
mouse.
These commands only apply to SDRK/6AD Local Hubs having firmware
versions ‘S50’ and above.
Command Key Sequence
Private Mode <Scroll Lock>
Lock out the remote console by triggering a ‘Private Mode’ function. This prevents
the remote console from being used even if the two second inactivity timeout period
expires.
During a Private Mode session, the extender system:
• Flashes the Scroll Lock LED on the local keyboard.
• Illuminates all three LEDs on the remote keyboard.
• Displays a blank image on the remote console’s monitor.
• Locks the remote console’s keyboard and mouse.
• Stops audio transmission.
Reset Local Keyboard and Mouse <Num-Pad Up Arrow>
Reset the local console’s keyboard and mouse. You may need to do this if you have
hot-plugged a keyboard or mouse and it has not initialized correctly.
Mouse Recovery <Num-Pad Left Arrow>
Use this command if you experience erratic movement of the mouse pointer or you
have lost mouse movement after hot plugging the Local Unit into the CPU. In the
case of erratic mouse movement, you may need to enter the command a number of
times to re-synchronize the mouse signal. Alternatively, stop moving the mouse for a
few seconds and the operating system’s mouse drivers may automatically re-
synchronize the signal. If the Local Unit has been hot-plugged, this command will
issue a request to the OS to initialize the mouse. Use this command with care.
