Situation
I have 5 baseboards, all of which are planned for simple separation and storage, none of which are more than 4ft x 14in.  I would like to stick to Plan A, which would be to use a single DCC Bus, connected between each board, by soldering the Bus to the pair of Pattern Maker's Dowels which locate the boards together.  Points and signals are intended to respond to paired Accessory number commands, hopefully in a  matching and synchronised manner.

As matters stand, much of the planning and hardware is sorted, using an DCC Concepts Alpha Encoder, to send Accessory control numbers out along the Bus, with an Alpha Mimic to show the results, on a small Control / Mimic board.  I have a DCC controlled Peco Smartswitch, for Servo control of the points, which will also send appropriate power to switch LEDs {which will suit many versions of signals}.

I like the Ground Signals in the Alpha Ground Signal set, very good looking  -  and plug-in simplicity, so much so that I have a set which I will use.  My intention to use Alpha Ground Signals, reveals a snag, hence my post.  The problem is simple to identify, because the Alpha Ground Signal control board will have to be in a single location on one board and would need wires to the other base-board where the other Ground Signals are located.  {Back to the initial idea of a single DCC Bus}  This doesn't fit that initial brief, of course.

Discussion

It would seem that, one solution, might be to use the Alpha Ground Signals set, with it's control board on one of the baseboards, and find another means to operate the remaining Ground Signals on the only other Baseboard which needs them.  Would it be possible to use the DCC Concepts DCD-SDC3 Converter 3 wire to 2 wire packs to make use of the Smartswitch LED, 3 wire, output, for the {DC Reversing} Ground signals in the Alpha pack, on the other baseboard?

Edit: to add that the Smartswitch LED outputs are Direct fit for LEDs and, Red/Common/Green, SPDT.

Yes, that should work. Don't forget to add appropriate resistors etc as needed.... to balance light intensity and protect the LEDs.

If you are only looking at ground signals on one other board then why not use separate plug in contacts to operate those signals.  You don't say how many signal units you will be using and how many aspects those signals are so I'm not sure how many individual wires we are looking at here.

Thoughts of the top of my head would be to use audio cable 3.5 or 2.5 mm solderable jack plugs and sockets.  These could even be four pole plugs which would allow you to connect four wires.  The advantages there are very quick, easy and reliable connections.  Just have a couple of tails hanging down close to each other ready for connection when the boards are clipped together. 


This type of thing, with an equivalent socket of course:

Thank you, both for the clear information, which is all very useful.  I am glad that I didn't have to go out to buy, 7 from memory, 3 x wire Red/Comm/Green signals, {currently enjoying a dose of refreshing Cornish rain and Anyrail won't work on my Apple laptop} as the DCC concepts are very good and others would be unlikely to match them well.  There's also that, niggling, miserly attitude that resists buying replacement items for something I've already bought and like, much more satisfying to exercise the little grey cells.

Your help is much appreciated.

The Jack-plugs will be ideal for the Turntable, too, as it gets lifted out and in.
