CASCADING
The UNIMUX-USBV-4O USB KVM switch can be expanded to access up to 128 CPUs by cascading multiple units together. As
many switches as there are CPU ports may be connected to a UNIMUX-USBV-4O USB KVM switch. Single user and multi-user
UNIMUX switches may be connected downstream (see Figs.16 and 17). The first switch in a cascaded system is referred to as
the "master", while all downstream switches are referred to as "slaves". The only additional hardware required to cascade
switches is a set of device and monitor cables for each “SLAVE UNIT” (see MATERIALS on page 1). All CPUs and switches can
then be controlled by users using OSD commands with Command Mode.
Note: The UNIMUX 4 port USB KVM switch must have OSD installed to use cascading.
Note: Cascading is not an option in the UNIMUX-USBV-2 2 port USB KVM switch.
