NTI UNIMUX SERIES USB KVM SWITCH
20
DDC
The UNIMUX is designed to transfer DDC information from the monitor to the CPU so that the CPU is able to update EDID data
about the monitor it connects to.
DDC information is downloaded from the attached monitor and stored in the UNIMUX when the UNIMUX is first power-ON
(monitor must be ON first), or by pressing the “DDC” button after the UNIMUX is powered-ON (used when hot-plugging the
monitor).
Note: Make sure your monitor is in digital DVI mode (not analog DVI) for video to be viewed and for the proper EDID table
to be communicated to the CPU.
Once the DDC information is recorded, the UNIMUX will transfer it to each connected CPU.

AUDIO SUPPORT
(Optional)
Models with audio support include 3.5mm stereo jacks for connection to audio sources and an output device. Audio from either
the same sources as the video, keyboard, and mouse or from separate sources (any standard line level audio source
(1.23Vrms/3.47Vp-p max.)) will be heard through devices such as self-powered stereo speakers or headphones.
Audio signals are switched along with the keyboard, mouse and video signals using the buttons on the UNIMUX switch.
Connections to “AUD IN” ports will switch at the same time as like-numbered “CPU” ports when controlling the switch. For
example, if “CPU 1” is switched to “CPU 2”, then “AUD IN 1” will also switch to “AUD IN 2”.
