Page 8 INTRODUCTION FEATURES Thank you for choosing SPLITMUX-DVI-4 from NTI. This product represents the latest state-of-the-art tech- nology in keyboard-video-mouse (kVM) switching. The SPLITMUX-DVI-4‘s key advantage over conventional kVM switches is that it allows you to simultaneously display and administer 4 computers on a single console. It combines key features of a high-end kVM switch and a digital multiviewer scaling and converting videos at both inputs and output.
Page 9 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-DVI-4. It supports any combination. To connect the console, SPLITMUX-DVI-4 features two USB ports for mouse, keyboard, touchscreen or trackball connection.

Page 30 Default setting is “off”, which prevents any external CONTROL. Use a serial cable to connect a control unit to the RS 232 port (RJ 45) on the SPLITMUX-DVI-4 rear panel. To synchronize several devices, special Y cables are required. Settings for the connection are:...
Page 31: Example Of Dcp Control
(see example on page 70) Important: Each time you restart a SPLITMUX-DVI-4 set to synchronize, it will send all its settings to the next connected device. This process also takes place after activating synchronize in the OSD menu. When starting a chain of devices, always start by first switching on the device at the end of the chain.
Page 32: Example Of Dcp Synchronization
To synchronize, SPLITMUX-DVI-4 1 sends every change in settings as a DCP message via the serial Y cable to the RX input of SPLITMUX-DVI-4 2. SPLITMUX-DVI-4 2 adopts the settings and sends a DCP message via TX output over the Y cable to the RX input of SPLITMUX-DVI-4 3.
