The operation of Standard and Audio/Serial Remote Units is slightly different. Please read the

section appropriate to your system.

4.1 Operating Standard Units

Micro Extender Remote Unit: ACUMREM

Micro Extender 6-port Remote Hub: ACU1006MRA

Scroll Lock Function

Standard Remote Units use the Scroll Lock key for system commands. The following table

lists the commands available at a Standard remote console:

Command Key Sequence

Reset Keyboard and Mouse

All except ACU1007A

Reset the remote console’s keyboard and mouse. You may need to do this if you have

plugged a keyboard or mouse into a powered Remote Unit and it has not initialized

correctly.

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.

Activate Console

ACU3009A only

Any key or mouse action

Gain control of CPU from local console. Only operates if local console has been inactive for

at least 2s.
