Yes. The original setting device on the 506 was a DIP with frangible
foil jumpers that bridged opposite pins. In that case, you severed the
ones that you wanted to open. Sounds as though you have a DIP switch so
atart with all OFF and turn on those that correspond to 'D' and 'H' and
the appropriate 'DSn'. Your mention of a WD-GEN controller says PC, so
if using a cable with a twist it should be DS2. Make sure that it is a
HD cable - the twist is fewer leads and in a different location on the
ribbon cable. Also, don't overlook the 20 conductor cable also.
