Control over the computers attached to the NTI Universal KVM switch is achieved through operation of the Universal KVM switch.
Once the Universal KVM switch is properly connected, the Universal KVM switch will enable a connection to be made between the

KEYBD ports. The lights on the control panel of the Universal KVM switch will illuminate depending on which port (and
s u b s e q u e n t a s s o c i a t e d c o m p u t e r ) is being connected to the keyboard, monitor, and mouse. The choice of which computer a
keyboard, monitor, and mouse will be connected to is determined by controlling the Universal KVM switch either through the front
control panel on the Universal KVM switch, by keyboard control, or by optional methods such as Wired Remote Control, RS232,
Infrared, or an On Screen Display. An LCD display can also be added to enable selection and control of computers by name.

There is a touch-switch and LED on the front panel of the Universal KVM switch for each computer the switch will connect
the keyboard, monitor, and mouse to. Pressing any touch-switch on the front panel of the Universal KVM switch will connect the
selected computer to the keyboard, monitor, and mouse.
Holding down any front panel touch-switch for more than 2 seconds will cause the Universal KVM switch to cycle through all
