Setting the jumpers
Set the jumpers on the DP-501 as follows. (In the case of a Y connection, the jumpers may have any setting since

Attaching the customer display
The serial connector inside the DP-501 is attached using inch screws (hexagon nuts). If millimeter screws
are necessary, replace them with those supplied as accessories. Inch and millimeter screws can be distin-
