Hi Bruce,
In the files section (
https://ammrl.groups.io/g/main/files )
of ammrl.group.io, there are a number of hardware manuals. The
pinout you are looking for is on page 10 of the Highland VT
controller manual. Note that two of the pins need to be type T
alloys, not the standard copper of replacement DB 9 connectors.
