Programming CVs with NCE

[cmajer]

Connecting the SC1 to the NCE Power Pro test track does not allow CVs to be changed because the decoder cannot be read.

I have 3 aspect signals supplied by Absolute Aspects, each has Theater Route Indicators with 5 display characters. I have set the address of one signal to 339 using the PGM method. It would appear that red/yellow work in reverse hence I assume not common cathode.

I had a look at JMRI Rosters and found the Harman Signalist Accessory Decoder entries for V0.21 and V0.23. My SC1 says V1 Issue 2 so not sure which to use?

Tried V0.21 and gave the Roster the name Signal 339. I then used output address mode and set the address to 339. I then changed the CV table as required i.e.  CVs
35=255
37=128 
38=8

I have saved the Roster.

I am not accustomed to using Rosters - what do I do now to program the signal?

I have now worked out that DecoderPro is better than PanelPro as it has read and write buttons. Although Programming on the Main doesn't work, programming using the test track does and the aspects flash whilst changes are made.

The signal is common cathode after all - I tested it with a 9V battery, so not sure why OFF selects red and ON selects Yellow? Setting CV35=255 didn't do what I expected so I will reset to 0.

CV37=128 by my calculation should have made red come on after a reset which it did but then setting it to red made it go out and I couldn't get red again without a reset so that one needs to go back to 0.

Hopefully I will get the hang of these settings after starting again!

I just can't get the SC1 to behave. With CV38=8 it should be a simple case of using addresses 339 to 347 to control the 8 outputs but I can't control the aspects and the route indicator has all segments on by default and sending some addresses makes some segments go on and off. I'm running out of ideas!

I have now read all CVs in a brand new SC1 and there is a huge discrepancy in CV values compared with the troublesome one - many of the unpublished CVs were different. I have now copied the CV values across and it now works apart from output bits 7&8 which are permanently on. Anyone know a CV that could cause this?

Problem solved - the base address must be nx4+1 and I was 2 out hence the last two outputs couldn't be addressed.
