How do I terminate the video sync signal on a DVM/HD?
By default, the DVM/HD is configured to terminate the sync input with a 75 ohm load. However, this termination can be removed with a configuration jumper if necessary. This 2-pin jumper is located on the DVM/HD Decoder Card inside the DVM/HD chassis. The jumper header is directly beside the gold connector that links the card to the Sync input.
When the jumper is connecting the 2 pins, the 75 ohm termination is enabled. To disable the termination, simply remove this jumper.
