Product Description
The U97-H2 is a KVM+audio+RS-232 extender. The U97-H2 extends dual
video outputs, keyboard, mouse, audio and RS-232 to the remote station
with a local station as well. It allows a local user and a remote user to
work on the same PC. The remote user can be up to 500’ away via a Catx
cable connected between the Sender and the Receiver units of the U97H2. The Receiver unit of the U97-H2 has independent digital video
compensation control for both the A and B video outputs. The digital
compensation control is controlled via hot keys on the remote keyboard.
The Sender unit of the U97-H2 has an external control switch that will
allow only local control, or only remote control, or either station control.
The Sender unit also has 2 LEDs to indicate which station, local or
remote, currently has control. Both Sender and Receiver units have an
LED that when a Catx cable is connected and both units are powered on,
the LED will light up indicating successful communication via the Catx
cable.

Operation
The U97-H2 will allow only the local or remote to communicate with the
PC at any given time. After either stations stops sending keyboard or
mouse data, there is a 2 second delay before the other station can start
sending data to the PC. If the Local LED on the Sender is lit then only the
local station may communicate with the PC. If the Remote LED on the
Sender is lit then only the remote station may communication with the PC.
If neither LED is lit then either station may communicate with the PC. As
soon as one station begins to communication with the PC, that LED will be
lit and the other station will not be able to communicate with the PC.
The Link LED on the Sender and the Link LED on the receiver indicate
when there is a successful link between the Sender and Receiver units. If
the Link LED’s are on then there is a successful link between the Sender
and Receiver.
How to control the video compensation
KVM EXTENSION OVER UTP FOR DUAL VIDEO PC’s
The digital video compensation is controlled by hot keys on the remote
keyboard. The hot key sequence is “Scroll Lock” “Scroll Lock” “a” for the A
video channel or “Scroll Lock” “Scroll Lock” “b” for the B video channel . You
will have 2 seconds between each keystroke to successfully complete the hot
key sequence. Once the hot key sequence has been successfully completed,
you will see the Num Lock, Scroll Lock, and Caps Lock LED’s cycling on the
Remote Keyboard. This will indicate you are in the video adjustment mode.
Use the “+” and “-“ keys to increase or decrease the video compensation as
necessary. Pressing the “Enter” key will adjust the video compensation to full
compensation. Pressing the “Esc” key will adjust the video compensation to no
compensation. Press any key other than “+”, “-“, “Enter”, or “Esc” to exit the hot
key sequence. When you exit the hot key sequence, the LED’s on the
keyboard will stop cycling and will return to their previous state
