NTI UNIMUX SERIES USB KVM SWITCH INTRODUCTION The UNIMUX-DVI-x 4,8 or 16-Port USB DVI KVM switch (UNIMUX) allows access to up to sixteen (16) Windows, MAC, or SUN USB CPUs from one USB keyboard and mouse and a DVI video-enabled monitor. 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.

NTI UNIMUX SERIES USB KVM SWITCH RACKMOUNTING INSTRUCTIONS This NTI switch was designed to be mounted to a rack or to set 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.
NTI UNIMUX SERIES USB KVM SWITCH INSTALLATION 1. 2. It is not necessary to turn the CPUs or monitors OFF during this installation. Connect a HDMI-to-DVI cable (supplied) from a DVI monitor to the HDMI connector labeled with a monitor symbol ( on the front of the UNIMUX (See Fig. 3 below.
NTI UNIMUX SERIES USB KVM SWITCH 5. Connect each CPU to the USB switch using a DVI-HDMI-MM-x (x=3, 6, 10, or 15 foot) cable for each video connection and a USB-AB-yM (y= .5, 1, 2, 3, or 5 meters) for each input device connection – REQUIRED (not supplied). (See Fig. 5 below.) Cables are available from NTI. 6. Group the input device and monitor interface cables from each CPU, making sure that cables from the first CPU are connected to the UNIMUX at connectors CPU 1 and VIDEO 1.
NTI UNIMUX SERIES USB KVM SWITCH RS232 Connection If the RS232 option is installed, connect one end of the CAT5 patch cable (supplied) to the port labeled “RS232” on the rear of the UNIMUX. Plug the other end of the CAT5 cable into either the RJ45-to-DB9 or RJ45-to-DB25 adapter supplied, and connect the adapter to the RS232 port on the control terminal. Follow the instruction under “RS232 Control” on page 12 for configuration and use of the RS232 control feature.
NTI UNIMUX SERIES USB KVM SWITCH Power-Up Sequence • • Power-up the monitor(s). The UNIMUX can be powered at any time. Note: It is recommended that the monitor be powered-ON before powering on the UNIMUX in order for DDC information to be properly communicated. • • The CPUs can be powered at any time although if a CPU needs a keyboard and/or mouse at power-ON it should be powered after connecting to and powering-ON the UNIMUX.
NTI UNIMUX SERIES USB KVM SWITCH USING THE UNIMUX DVI KVM SWITCH Once the UNIMUX is properly connected, the UNIMUX will enable a connection to be made between the CPUs attached to its VIDEO and CPU ports and the monitor and input devices attached to the MONITOR and USB Device ports. The LEDs on the control panel of the UNIMUX will illuminate depending on which port (and corresponding CPU) is being connected to the monitor and input devices.

NTI UNIMUX SERIES USB KVM SWITCH Select Country Code It is possible to configure the UNIMUX to emulate a specific international Sun keyboard regardless of what actual keyboard is connected. This is recommended when the CPU needs the layout code (i.e. a SUN CPU) and the keyboard doesn't have an explicit layout code (i.e. some Windows keyboards). To do this, manually set the UNIMUX to indicate the international keyboard identification number to the CPU using the following procedure; 1. 2. 3. 4.
NTI UNIMUX SERIES USB KVM SWITCH RS232 CONTROL (Optional) RS232 enables the UNIMUX to be remotely controlled via RS232.

NTI UNIMUX SERIES USB KVM SWITCH Command Protocol RS232 commands supported by the unit are defined below. All command strings should be terminated with a (carriage return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the command definitions. All characters in the command string should be upper case, and all numbers below 10 should have a leading 0 (ex: 1 = 01).
NTI UNIMUX SERIES USB KVM SWITCH NTI Switch Control Program For Windows 9X, NT, 2000, XP, And Vista The NTI Switch Control Program is an easy and powerful graphical program that controls NTI switches through an RS232 interface. The NTI Switch Control Program is included on the CD packaged with the UNIMUX. The NTI Switch Control Program is downloaded by clicking on the link "Download NTI Switch Control Program". To install the NTI Switch Control Program after downloading 1. 2. Locate the Setup.

NTI UNIMUX SERIES USB KVM SWITCH KEYBOARD FEATURES The keyboard configuration of each CPU is saved in the UNIMUX. For example, if the CPU attached to Port 2 had CAPS LOCK and NUM LOCK selected the last time that CPU was accessed, then they will automatically be set when that CPU is accessed again. Keyboard-To-Computer Translation (See Fig. 14 on page 18 for reference.) The UNIMUX enables a mixture of otherwise incompatible peripheral computer components to be connected together.

NTI UNIMUX SERIES USB KVM SWITCH TROUBLESHOOTING PROBLEM: SOLUTION: Keyboard Errors Check cable connections on each CPU and the switch. PROBLEM: SOLUTION: No Video Check cable connections on each CPU and the switch. Verify that keyboard and video connect from each CPU to matching ports. After reconnecting, CPU may need to be re-booted in order to sense the monitor connection. PROBLEM: SOLUTION: No Mouse Movement Check cable connections of mouse. Verify that mouse driver was loaded.
