28Computer video compensationThe video compensation for connected computers is achieved using the mainmenu. Although the compensation can be applied from any local, remoteor global user port, it is best achieved using the local user port because thisprovides the most direct view of the computer output. The compensationis achieved simply by registering the link cable length, however, differentcables can vary in their characteristics so it is often useful to ‘fine tune’ thecompensation by eye.Note: CATx cables below 10m give very little loss and so it is not normallynecessary to be concerned about setting any computer video compensation ifshort CATx cables are being used between the AdderView CATx and the CAMfor each computer.To apply computer video compensation1 Place a computer (connected via its CAM and category 5, 5e or 6 cable) intothe highest resolution video mode at which it will be used.2 If possible, use a monitor and keyboard connected to the AdderView CATxlocal user port.3 Display the AdderView CATx main menu and use it to select the appropriatecomputer.Note: You must highlight the computer name and press to select it.4 Press to access the compensation feature:Ensure that the appropriate computer ismarked by the arrow - if it is not marked,the computer is not correctly selected andthe compensation will not be applied.The value in the green area indicates thecurrently selected cable length.5 Use and to increase or decrease the stated cable length, as required.Note: As you adjust the Length value, check the video image for signs ofunder- or over- compensation, especially to the right hand side of any hardvertical edges of images.6 When the correct compensation has been applied, press to quit thescreen and save the settings.
