LOCAL UNIT OPERATION

5. Local Unit Operation

5.1 Overview

For more information about serial/audio port operation, see Appendix E: Audio/Serial

Ports, page 45.

Keyboard and Mouse Emulation

Local units have keyboard and mouse emulation. The attached PC operates normally without

requiring a keyboard or mouse to be attached to either the Remote or Local units (in the case

of a dual access system). You can therefore replace any keyboard or mouse attached to the

extender system without disrupting the operation of the computer.

Power

Local units (ACU2201A-R2 and ACU2222A-R2) may require an external 5V PSU

(PSU1006E):

• For video only applications.

• If the PC cannot provide sufficient power through the keyboard connection.

5.2 Dual Access Systems

ACU2209A and ACU2228A models offer dual access from consoles at both Remote and

Local units. This operates on a first-come, first-served basis. When one console is in use, the

system blocks out the other console until there is no keyboard or mouse use at the active

console for two seconds. Both monitors show the current activity on the computer

irrespective of which console is in use.

Only Reset and Private Mode commands are available at the Local unit. If you want to

configure the Extender system (for example, change DDC emulation) or tune the video

signal, see page 26; these commands can only be issued from the Remote console.

To enter these commands:

1. Press and release the initial ‘hot’ key sequence.

2. Press and release the command key (see opposite).
