SPLITMUX - Installation and Operation Manual
INTRODUCTION
1
Thank you for choosing SPLITMUX-DVI-4RT from NTI. This product represents the latest state-of-the-art tech-
nology in keyboard-video-mouse (KVM) switching. The key advantage of the SPLITMUX-DVI4-RT (SPLITMUX)
over conventional KVM switches is it allows you to simultaneously display and manage 4 computers on a single con-
sole. It combines key features of a high-end KVM switch and a digital multiviewer, scaling and converting videos
at both inputs and output.
DISPLAY MODES
Quad mode u
In this mode, the screen is split into four fields of equal
size; each displaying the entire screen contents of one
source.
tFullscreen mode
In Fullscreen mode, one of the four sources
is displayed in full screen size and maximum
resolution.
PiP mode (Picture in Picture) u
Using this feature, the full screen display of one of the
four video sources is accompanied by one to three small
images (thumbnails) of the other video sources which
are displayed on the right hand side of the screen allowing
simultaneous monitoring.
FEATURES
tWin mode
In Win mode each video source is displayed in its own
separate, detached window. Each of these windows
can be freely positioned and their height and width
can be adjusted. Transparency can be set. Positioning
is done using either the Hotmouse function, the front
panel or the touch screen. Presets of the window
positioning can be saved.

DVI & VGA
SPLITMUX supports resolutions of up to 1920 x 1200 @ 60 Hz for both DVI and VGA.
Any combination of VGA and DVI at all standard resolutions is possible at inputs and output. Analog video input
is converted to digital. If an analog display is connected, SPLITMUX converts the digital signal to analog
at the output. Internally, SPLITMUX processes video purely digital guaranteeing superior digital image
quality.
USB & PS/2 for keyboard / mouse / touch screen / trackball
Use either PS/2 or USB ports on the computer to connect keyboard and mouse to SPLITMUX. It supports
any combination. To connect the console, SPLITMUX features two USB ports for mouse, keyboard,
touch screen or trackball connection.
Transparent USB 2.0
SPLITMUX features a transparent high speed USB 2.0 matrix: USB 2.0 devices (e.g. printer, external
memory, memory stick,webcam, 3D mouse, finger printer) can be switched to computers connected.
Operation
There are six ways to operate SPLITMUX, switch channels, and select display modes:
1. Using the buttons on the front of the unit
2. Using configurable hotkeys (default HOTKEY is <Ctrl> + <Alt>)
3. Using the unit’s external configuration software on a remote computer
4. Via a serial port using the protocol DCP XML
5. Using mouse functions (Hotmouse)
6. Using a touch screen
The configuration of SPLITMUX is carried out by means of an On Screen Display (OSD) that can be
opened and navigated either with keyboard commands, front panel buttons or remotely via ConfDev on an
external PC.
The LEDs on the front panel indicate the unit’s current status.
Use the serial (RS232) or USB port for remote control and firmware updates.

been selected and is available for keyboard and mouse access. When a LED flashes
green, there is no signal at the video input of the selected channel.
An LED lights up yellow when there is a signal at the video input, but another channel
has been selected.
When the LED is dark, there is no signal at the video input and another channel has
been selected.
The LEDs light up blue when Win Mode preset window configuration is being selected.

Setting output resolution to safe output modes
To set output resolution to 640 x 480 pixel @ 60 Hz simultaneously:
Press and hold buttons 1 and 2 for 2 seconds.
Use of this feature is recommended when you cannot use the OSD (on screen display dark or illegible)
