NTI UNIMUX MULTI-USER KVM SWITCH

CASCADING
The UNIMUX USB Matrix switch can be expanded to access up to 512 CPUs by cascading multiple units together. All
downstream switches are referred to as "slaves" in a cascaded system. The only additional hardware required to cascade
switches is a set of device and monitor cables for each “SLAVE UNIT” (see MATERIALS on page 3).
All CPUs and switches can
then be controlled by users using OSD commands with Command Mode.
Limitations
The front panel keypad is only used to operate standalone switches. To control a cascaded network of switches, only the OSD
commands within Command Mode will be recognized.
Users connected to accessible ports on downstream slaves (i.e. ports not connected to the master) will not be able to control
switches or CPUs connected upstream. Only control over CPUs and slaves downstream from a user's connection point will be
enabled. (See Figure 48)
Slaves connected downstream from a master must be switches with at least as many user ports as the master. I.e. If the master
is UNIMUX-4X32, connected slaves can be any switch with 4 or more user ports.
In order for each user that is connected to the master to view and control CPUs connected to slaves, a number of user ports from
each slave equal to the number of user ports on the master must be connected to the master. i.e. If the master has 2 user ports,
and the slave has 4 user ports, then at least 2 of the 4 user ports on the slave must be connected to the master.
Exception: If the master is a single user UNIMUX switch, slaves connected downstream can be any size multi-user
UNIMUX switch (see Figure 49).
