Switch Installation – Multiple units – “BUS” topology
A “BUS” configuration is usually used when all the users are connected
to the KVM ports on Unit #1. In a “BUS” configuration, (Figure 4) the
video path is from the last Unit in the configuration to the first Unit
(“OUT” to “IN”). KVM users on the first Unit can access all computers
on all Units. Users connected to Unit #2 can only access computers on
Unit #2, 3, etc.
Figure 4. Bus configuration
The Units in Figure 4 can be any UltraMatrix 2xE or 4xE model.
Upper expansion card and cabling are on the 4xE model only.
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(s) with a jumper installed on JP1.
(NOTE: Jumper JP1 is factory installed on all expansion cards)
