Thanks for the responses.? After further work I have solved the problem of display on start-up.? I set up a LogixNG command in JMRI to query all sensors.? This is invoked when JMRI starts up and does correctly display the condition of all the sensors.

I have some further work to do because a few sensors don't always report properly when turnouts are switched.? This might be because I haven't used twisted cable for the RS connection to the LZV100.? That's the next thing to try...
