The SUSIC was working and if all up stream from it to the computer remained unchanged you should get the 1 to 1 blink...? I say that not sure if it initializes without it's cards set right... Let's assume that the computer to the SUSIC is okay and there is a change at there... You would still see the data in light blink on the 232/485 and SUSIC it wouldn't initialize if it's address changed. If a baud rate problem there should be fast blink if the address is right (or wrong?) Be sure the DIP switches are as they were when you at least had inputs.
Any change at the computer end that might have caused JMRI to forget the SUSIC and/or I/O? Check there first even if the computer changed the com number.
Then pull the I/O cards and with just the SUSIC and MB see if you can get that back at least to the data lights and maybe the heart beat.
If we get this back to where it was when first posted we'll need to if the outputs are working... rather than a loop back to an input we'll want an LED to the pin tested. LED to +5 and through 330/470 resister to pin.
If this goes too much longer I'll dig my SUSIC and I/O 24's out of storage and play along with any further tests... rather not but it would be nice to get this one working.
