Adder Technology CATX-USB manual Computer video compensation, To apply computer video compensation

Computer video compensation

The video compensation for connected computers is achieved using the main menu. Although the compensation can be applied from any local, remote or global user port, it is best achieved using the local user port because this provides the most direct view of the computer output. The compensation

is achieved simply by registering the link cable length, however, different cables can vary in their characteristics so it is often useful to ‘fine tune’ the compensation by eye.

Note: CATx cables below 10m give very little loss and so it is not normally necessary to be concerned about setting any computer video compensation if short CATx cables are being used between the AdderView CATx and the CAM for each computer.

To apply computer video compensation

1Place a computer (connected via its CAM and category 5, 5e or 6 cable) into the highest resolution video mode at which it will be used.

2If possible, use a monitor and keyboard connected to the AdderView CATx local user port.

3Display the AdderView CATx main menu and use it to select the appropriate computer.

Note: You must highlight the computer name and press to select it.

4Display the AdderView CATx main menu again.

5Press to access the compensation feature:

Ensure that the appropriate computer is marked by the arrow - if it is not marked, the computer is not correctly selected and the compensation will not be applied.

The value in the green area indicates the currently selected cable length.

6Use and to increase or decrease the stated cable length, as required. Note: As you adjust the Length value, check the video image for signs of under- or over- compensation, especially to the right hand side of any hard vertical edges of images.

7When the correct compensation has been applied, press to quit the screen and save the settings.
