INSTALLATION INSTALLATION 1. It is not necessary to turn OFF power to either of the CPUs that will be connected to the UNIMUX-USBV-2 USB KVM switch before connecting or disconnecting any cables. NOTE: If a CPU needs to identify a keyboard, it will be necessary to power ON the CPU after it is connected to the UNIMUX-USBV-2 USB KVM switch and only after the keyboard is connected and the UNIMUX-USBV-2 USB KVM switch is powered ON. 2. Connect a USB keyboard to a femal

5. Using a USB-AB-x-MM cable connect the USB type A device port of a USB CPU to the USB type B port labeled "CPU 1" on the UNIMUX-USBV-2 USB KVM switch. 6. Using a VEXT-xx-MM connect the video port of the same USB CPU connected in step 5 to the female 15HD port labeled "VIDEO 1" on the UNIMUX-USBV-2 USB KVM switch . Be sure to tighten the two screws on the cable connector to the UNIMUX-USBV-2 USB KVM switch securely. 7. Repeat steps 5 and 6 for connecting a second USB

POWER-UP SEQUENCE The UNIMUX-USBV-2 USB KVM switch can be powered at any time. 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-USBV-2 USB KVM switch. USB devices (keyboard and mouse) can be hot plugged to and from the UNIMUX-USBV-2 USB KVM switch at any time. Remember, the last attached device is the active one.

Scan Mode Scan Mode is indicated by a flashing CPU port LED. In Scan Mode the switch scans back and forth between ports making the CPU connected to the port with the flashing LED active. That connected port will remain active while in use. When the connected port becomes idle for the user selected time out period (default time is 5 seconds), the UNIMUX-USBV-2 USB KVM switch will connect to the other CPU port. See Command Mode section on page 5 for configuring the scan time out period. Fig.

KEYBOARD FEATURES KEYBOARD FEATURES The keyboard configuration of each CPU is saved in the NTI UNIMUX-USBV-2 USB KVM switch. 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. (See Fig. 4 on page 9 for reference.) Keyboard-To-Computer Translation The NTI UNIMUX-USBV-2 USB KVM switch enables a mixture of otherwise incompatible peripheral computer components to be

It is also possible to configure the UNIMUX-USBV-2 USB KVM switch 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-USBV-2 USB KVM switch to indicate the international keyboard identification number to the CPU using the following procedure; 1.
