5. Local Unit Operation
5.1 Overview
For more information about serial/audio port operation, see Appendix E: Audio/Serial
Ports , page 47.
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 may require an external 5V PSU (PSU1006E-R3):
•
For video only applications.
•
If the PC cannot provide sufficient power through the keyboard connection.
5.2 Dual Access Systems
ACU3209A and ACU3228A 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 28; these commands can only be issued from the Remote console.
To enter these commands:
1. Press and release the initial ‘hot’ key sequence.
<Left Control> + <Left Shift> + <F10>
2. Press and release the command key.
