I am looking for operating information for the Devtronix 293-1B MIDI
Processor circuit board and the Devtronix 293-3A MIDI Output board.
Devtronix made these boards sometime in the mid-1990s. My setup was
working when I last used it (many years ago) with a different computer
(probably Windows 3.1) and MIDI adapter.

I have been able to get the boards powered up and the "MIDI activity"
LED does flash when I play a MIDI file through my current setup
(Windows 11 through a USB-to-MIDI adapter). The MIDI Output board,
however, does not send any signals to the Reisner magnet valves. I am
thinking there might be an issue with track and or channel numbers
with my new setup.

There are a bunch of jumpers on both cards and I am looking for any
documentation that might be available that explains what they are for.
Any help would be appreciated.
