Hi JMRI user group,

This little black duck in St. Clair, Sydney, finally got some signalling up & running, sort of...

Is there any known issue[s] with JMRI and NCE that would cause JMRI to correctly show? the aspect? of a given [3 aspect] signal, BUT have the equivalent physical signal on my layout inconsistently update [or not] its aspect??

Note I said 'inconsistently', because some of the time a given signal will update correctly, another time not. [And it is not always the same signal that fails to update; it all appears rather random.]

?

SOME DETAILS

Simple loop running at present under test. Approximately 15 signals in the? large-ish loop. Currently running LOGIX programmed to have one signal RED, one signal AMBER, the remainder GREEN.

Logix operates correctly 'on screen' or 'virtually'.

I have tried various ways of programming the signal sequence, but always run into the same problem of inconsistent updating of aspects.

?

HARDWARE - all NCE

NCE PowerPro, NCE BD20 sensors [all track 'sensed'], NCE AIUs, their channels switched via the sensors. Each signal is connected to an NCE 'Light-it' stationary decoder acting as its driver.

?

ADDITIONAL OBSERVATIONS

Signals, when manually operated from the PC [JMRI signal table] update as directed 'on screen' & 'on layout', no failures.

AIU on board channel indicators [LEDs] operate correctly and cause JMRI sensor table to shown sensors as 'active' or 'inactive' as expected.

At one point I thought there may be data loss occurring through the 'bus' between the NCE system and the signal drivers, but this doesn't appear to be the case. I say this because I have one of the signals connected to the 'track bus' within 6 inches of the NCE box - and it still fails to update at times.

I can't take the project any further until reliability of correct aspect be attained.

?

I can supply more detailed info to anyone who thinks they can help.

Regards,

Nimble
