NTI UNIMUX SERIES USB KVM SWITCH

CASCADING
The UNIMUX-USBV-x USB KVM switch can be cascaded as shown in Fig. 33 below. Single user and multi-user UNIMUX
switches may be connected downstream (see Figs.35 and 36). 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.
Notes:
•
Cascading is not an option in the UNIMUX-USBV-2 2 port USB KVM switch
•
Slaves in a cascaded system must be either all single-user switches or all multi-user switches, but not a
combination of both.
Configuration
In a cascaded system no additional configuration is necessary.
Cascaded Installation
a. Using the 15HD video cable ends of a USBVEXT-xx-MM cable, connect the USB KVM slave's MONITOR port to the master’s
VIDEO 1 port.
b. Using the USB ends of the same USBVEXT-xx-MM cable, connect one of the USB slave’s USB DEVICES ports to the
master’s CPU 1 port.
Note: Only one of the two ports labeled DEVICES on a slave needs to be used in order for cascading to work.
c. Repeat step a. & b. for each additional slave, keeping in mind that each slave will connect to the next available master’s
port (i.e. Slave #2 to master’s VIDEO 2 & CPU 2, etc.) See Fig. 35 on page 35.
d.
IMPORTANT: Power On each of the slave units first, THEN the master switch. (Whether the CPUs are powered-ON or not
doesn’t matter, but the UNIMUX slaves must be powered-ON first.)
