Totally understand. The B1 self-test is a rudimentary test that can be administered physically before connectivity is addressed. With that said, to test the software side adequately it might be easiest to run a run-once program. Just set a time of 1 minute for all stations you wish to test and ensure everything runs as desired. If you need further help starting a run-once program you may consult the reference here: http://rayshobby.net/?page_id=730#runonce or ask of course.
