20 CATx KVM Extender Local Hubs

Local Console Commands

On a dual access system, you can issue the following commands at the local

console:

Command Key Sequence

Activate Console

Any key and (optionally) mouse action

Gain control of CPU from remote console. Only operates if inactivity timeout period

has expired.

Start/End Private Mode

Start/End ‘Private Mode’ at local console. Private Mode prevents the remote console

from being used even if the inactivity timeout period expires.

During a Private Mode session, the extender system:

• Lights the Scroll Lock LED on the local keyboard.

• Lights the Scroll Lock LED on the remote keyboard.

• Locks the remote console’s keyboard and mouse.

• Displays a blank image on the remote console’s monitor. With SDLink/R and

SDLink/RS Remote Units, you can disable this feature by setting switch 1 on

the SW1 DIP switch block on the Remote Unit’s main circuit board to ON. In

this case, the remote monitor will continue to show PC activity during a

Private mode session.

• Switches remote CPU (SDLink/RSW only).

To end a Private Mode session, press the Scroll Lock key on the local console a

second time. Remember that each press of the local console’s Scroll Lock key also

resets the keyboard and mouse.

Reset Local Keyboard and

Mouse

press key twice to avoid starting/stopping Private

Mode session

Reset the local console’s keyboard and mouse.

Mouse Recovery

Hold down Left and Right Mouse buttons then press

and release <Scroll Lock>

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.
