ULTRACONSOLE USERS MANUAL
Switch Installation – Multiple units – “BUS” topology
A “BUS” configuration is usually used when the user is connected to
the KVM ports on Unit #1. In a “BUS” configuration, (Figure 3) the video
path is from the last Unit in the configuration to the first Unit (“OUT” to
“IN”). A user on the first Unit can access all computers on all Units. A
user connected to Unit #2 can only access computers on Unit #2, 3,
etc. Connect conflicts can occur with multiple users unless model
UC2-1X16U/E is used for unit #2 or Unit #3 (See Appendix F).
Figure 3. Bus configuration
The Unit in Figure 3 can be any UltraConsole model.
The “BUS” installation procedure is very similar to the single Unit
installation with the addition of connecting the expansion cables and
changing two configuration parameters, the “Starting computer”
number and the “Maximum computers” number. All Units in the system
must have an expansion card with a jumper installed on JP1.
(NOTE: Jumper JP1 is factory installed on all expansion cards)
