Looking deeper into the code, I see I need to know more things. I’ll recap:
System console so I can see:
Version of JMRI
Version returned by the NCE USB
The logged error message
NCE command station firmware version id
That’s either 1.28something or 1.65something.
?
But so far it is looking like you may not have the right jumper settings in the NCE USB and the version ID it is giving doesn’t match what it should be for the SB5 system. But depending on which jumper settings, the baud rate may also need to change to match what it expects.
?
But with the details above, I can guide the right answers.
