NTI UNIMUX 2-Port USB DVI KVM Switch

Scan Mode
Scan Mode is indicated by a flashing CPU port LED. In Scan Mode the switch scans back and forth between ports making the
CPU connected to the port with the flashing LED active. That connected port will remain active while in use. When the
connected port becomes idle for the user selected time out period (default time is 5 seconds), the UNIMUX will connect to the
other CPU port. See Command Mode section on page 7 for configuring the scan time out period.

NOTE: The keyboard and mouse must remain idle for the full scan time out period before the UNIMUX will connect to the
other port.
NOTE: Scan Mode not available on model UNIMUX-DVI-2-NBSC.
Broadcast Mode
(use with extreme caution)
Broadcast Mode allows the user to send keystrokes to all active CPUs. Broadcast Mode is indicated by illuminating the
CPU x LEDs in rapid alternating intervals . Broadcast Mode has some critical requirements:
a. Broadcast Mode must be OFF when booting any attached CPUs.
b. Broadcast Mode must be ON and the user must exit Command Mode for keystrokes to reach attached CPUs.
NOTE: The mouse is disabled leaving only the keyboard active during Broadcast Mode.
NOTE: Broadcast Mode not available on model UNIMUX-DVI-2-NBSC.
Normal Mode
The UNIMUX is in Normal Mode when only the LED for the active CPU is illuminated solid (not flashing as in Scan Mode). When
in Normal Mode, the user is controlling only the CPU to which the user is connected through the UNIMUX. In Normal Mode the
UNIMUX will only switch between CPUs 1 and 2 when the user uses either keyboard control or button control to do so.
Mice and Trackballs with MACs
The UNIMUX can be configured to enable full functionality between mice and trackballs having two or more buttons and USB
MAC CPUs. By default, the ports on the UNIMUX are configured for use with WINDOWS and SUN CPUs and have no special
translation for using multi-function mice and trackballs when a MAC CPU is connected. Using the commands in Command Mode
on page 6, either enable or disable this feature as needed for each port.
NOTE: Be sure to re-configure port for connection to a WINDOWS or SUN CPU if a MAC CPU is removed and a
WINDOWS or SUN CPU is then connected.
A flashing CPU LED means
that CPU is being scanned
and is active.
