Ray. Thanks again for your advise. It takes some time to set up the signals for all traffic flow variations but the effort is well worth it. I'm incredulous that HRMS engineers could even suggest that disabling an operational feature when using another without advising users could even remotely be described as a design feature. That said and having had much experience of working with software engineers over the years, I don't think it is unreasonable to suggest that they tend to operate in a world of their own. Still, now that I understand this "feature", all is good. Actually, very impressive. Many thanks for your support. BB

Thanks for your responses. Sorry for placing the question in the wrong place. I will follow your advise for setting up the signals, bazaar as the operational "design" appears to be.

Many thanks Chrissaf, St1ngr4y. Very helpful info - certainly fills the gaps in my knowledge. Fortunately I have a lot of Arduino project development experience having created (among 50 others, mostly not model railway related) a control system for a Hornby turntable. BTW, the design of the turntable is quite good but the manufacturing of it is unbelievably poor for a leading manufacturer. (probably outsourced, that's a sure way to loose control of quality) I spent more time working to free the binding parts of the turntable than I did developing the control system which is controlled by RM-Pro, via a loco definition. I used a different DCC decoder following a U.S. circuit and (probably older than the one used by RUDY) Arduino library. RUDY's example and the library he is using is MUCH easier to code for than the U.S. version. Re servo noise, I have 29 solenoid point motors and they make a lot of noise (I think) Sure there'll be some noise from the servos but if the action is slowed right down and if mounted in a 3D printed noise deadening holder, this will be more tolerable than the clack clack of the solenoid equivalent. I guess my main concern was not understanding enough about the NRMA system. As mentioned earlier, I had little trouble using a loco definition (8 function buttons selected 8 turntable positions) but didn't understand how the accessory decoder might interface with RM. Finally, thanks again for your timely support, much appreciated. Paul

I would like to use servos to move points rather than solenoids. Servos are quieter and the movement more realistic. To do this I will construct an Arduino based DCC decoder design I found on the internet. See the link here _ https://rudysarduinoprojects.wordpress.com/2019/05/13/fun-with-arduino-30-dcc-servo-decoder/. If I built one of these decoders, how might I be able to configure the DCC addresses I choose for each servo when designing the layout? I've used TrainTech accessory decoders before and they configure easily enough. I just want to be sure there's a way to configure single addresses before I start making the decoder. Anhy help much appreciated.
