NTI UNIMUX SERIES 4K VIDEO USB KVM SWITCH
INTRODUCTION
The UNIMUX-HD4K-x 4K Video USB KVM switches allow a single user to control of 4, 8, 16, 24, or 32 computers with an HDMI
monitor and USB keyboard and mouse. These switches feature an on-screen display (OSD) and a fully transparent USB switch.
(This means that when a USB device is connected to a transparent USB port, it is the same as if the device was being plugged
directly into the computer's USB port.) Connections use standard HDMI and USB cables.
HDMI 1.4 resolutions up to 4k @ 30Hz are supported.
The transparent switch is capable of supporting any two low-, full-, or high-speed USB 2.0 devices, including but not limited to
touchscreens, card readers, printers, scanners, and thumb drives.
Note: Devices vulnerable to data corruption upon surprise removal, such as thumb drives, have to be stopped by the us er before
switching hosts (i.e., by Windows safely remove hardware or Mac eject device). A warning to this effect, requiring user
confirmation, is displayed on the OSD when attempting to switch hosts or enter scan mode. This warning appears by default,
though it is possible to disable it in the switch settings.
Internal microprocessor circuitry allows all USB CPUs to be booted simultaneously without keyboard error. Port selection is
accomplished by front panel push buttons or commands typed on the keyboard. Port lights and status LEDs continuously update
on the front panel. Video formats up to 2560x1440 can be displayed from all platforms.
Features
HDMI 1.4, DVI compatible (with optional HDMI to DVI cable).
Resolutions to 2560x1440 (computer), 3840x2160 (UHD), and 4096x2160 (4K) @ 30Hz / 4:4:4 RGB (resolutions limited
to 1920x1200 when mounted in a RACKMUX drawer).
HDCP 1.4.
Supports low- or full-speed USB keyboard and mouse.
On screen display for controlling switch and modifying settings, uses attached mouse an d keyboard.
Synchronized 2-port transparent USB 2.0 switch.
Passes embedded audio.

NTI UNIMUX SERIES 4K VIDEO USB KVM SWITCH
RACKMOUNTING INSTRUCTIONS
This NTI switch was designed to be mounted to a rack or to sit on a desktop. It includes rackmount ears to make attachment to a
rack easy, and rubber feet to be applied to the bottom of the case if it will instead sit on a flat surface. If this will sit on a flat
surface, simply apply the rubber feet to the bottom of the case in each of the 4 corners.
To Mount to a Rack
1. Attach the ears to the switch using the 6-32x3/16" flat Phillips-head screws (6) provided as shown in the illustration below.
The holes in the ears should line up with pre-threaded holes in the sides of the NTI switch. Tighten the screws securely.

2. Install 4 captive nuts (not provided) to the rack in locations that line up with the holes in the mounting ear on the NTI switch.
3. Secure the NTI switch to the rack using four 3/16" diameter screws (not provided). Each screw should be of sufficient length
to go completely through the NTI mounting ear, rack frame and fully engage all threads in the captive nut. Be sure to
tighten all mounting screws securely.
4. Attach all cables securely to the switch and where necessary supply adequate means of strain relief for cables.
