CAT5 CABLE LENGTH SETUP

Jumper settings are used to set the focus of the picture and characters to the best possible

sharpness. The jump ers in the CAT5•9000R are set at the factory as shown in the diagram

below. The ﬁ rst step to adjusting the video is to have the CAT5•9000S and CAT5•9000R

con nect ed together with the CAT-5 cable that is going to be used in the in stal la tion. Then

set your computer to the resolution and refresh rate that you will be using most frequently

be using. Then open up the CAT5•9000R by un screw ing the bottom three screws on back

end of the box. Then two screws on each side of the box and the top. That is 9 screws in

total that need to be removed. Lastly the 4 hex bolts around the Monitor Out port and the

Video In port need to also be removed. After that look at some text on the monitor and

set the jumpers to the recommended jumper setting based on the length of your CAT-5

cable. If you still see some smear ing try moving all the jumpers up or down one from the

recommended setting. If you see smearing of just one color adjust an individual jumper

for the color that is smearing (it can be two colors). Repeat the same steps for monitor 2
