the best possible setting. Set the dip switches to the settings that are recommended
for the different lengths of CAT5 cable (see chart below). Verify that the picture quality
is to your satisfaction. If the recommended setting does not produce a great quality
picture, try using a different dip switch setting.The trim pod next to the VGAconnector
