18 CATx KVM Extender Local Hubs
3. Operation
Overview
The operation and configuration of dual access Standard, Serial and
Serial/Audio enabled systems is slightly different. Please read the appropriate
section for your system.
Dual Access, with consoles at both the Remote Unit and Local Hub port,
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 a set time: the Inactivity Timeout Period. Thereafter, any
keyboard (and, optionally, mouse) action at the other console switches activity.
Local Hubs offering dual access allow the user to lock out the remote console
by triggering a ‘Private Mode’ function. This prevents the remote console from
being used even if the inactivity timeout period expires.
For more information about serial and audio/serial port operation, see
Appendix B: Audio/Serial Ports: Operation & Multi-Port Configuration,
page 32.
Keyboard and Mouse Emulation
Each port on a Local Hub has keyboard and mouse emulation. The attached PC
operates normally without requiring a keyboard or mouse to be attached to
either the Remote Unit or Local Hub (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.
