Hi, I'm currently wiring my layout and have a query on wiring the Cobalt SS point motor.
In the manual, the diagram shows all the wiring from the point track piece to the frog connector on the control board. I understand the frog wire needs to in order to change polarity, but can the red and black wires come directly from the bus-wire instead? i.e. the same way as I install my Cobalt iP Digital motors.
Please see attached detail.

Yes - you can connect to the track or the DCC bus as they are the same circuit.

Cheers,
Mick

That's basically exactly how I've done it, as Mick says and how I looked at it, it is the same circuit anyway.

Thanks guys for confirming this. Didn't just want to go ahead in case I created a problem.

Hi all,
I have a new query.
How do I connect the SS motor to an accessory bus instead of the track bus?

Thanks

You have to install an additional bus for the purpose of supplying accessories only.  All accessories such as point motors, servos or any other decoder operated accessory can then be connected to this bus. Both busses are connected together at the controller but it seperates them on the layout and minimises the accessory bus being affected by power spikes in the track bus from locomotives.

Thanks BB I understand that and that's my main reason for adding one. I have downloaded a sheet from DCC Concepts site that shows how to wire the Cobalt IP Digital to the accessory bus and the track bus for frog polarity, but the SS manual doesn't offer any advice on wiring to the accessory bus, This is the info I really need.

Sorry, got it. 

In which case what I think you mean is that the frog switches, FROG PWR and SPDT-SW2 if you are using it to also power a frog as in a crossover or a run around loop, are connected to the track power.  The bus connections, labelled DCC/DC 12-23V on either end of the board are connected to the accessory bus and are what provide the power to the motor.

I'm sure one of the experts will confirm or otherwise when they get in tomorrow.

One the SS manual, your Accessory bus connection goes in to the connections shown as No1.
On the left or right end. 
The connections on the point diagram No 5 / 7.
these are shown as red /black Track power and Green as frog.
I hope this clears up the confusion.  
Regards.
John.

Thanks John,
I'll use the connections at No 7. I assume it doesn't matter which colour goes into each side as long as the frog is the centre one.

The frog is the centre connection. 
It does matter which side the track feeds are - it will short if they are wrong way round.

We cannot say exactly which way round the connections will be, as we do not know your left/right rail connections and orientation of the motor to the point.

You can pre-test it with a multimeter.

Set up the motor and get it working correctly for point tiebar position, then check for continuity between the centre terminal and either left or right terminal of the FRPG PWR connection.
Whichever is the continuous circuit, connect that side of the FROG PWR connections to the rail that is aligned with the frog.

Can anybody suggest suitable LED/LED's for use with the SS board 5 volt supply. I am looking to make a simple panel for a 3 track coaling plant using a three way point the point motors will be operated by computer and momentary switches. My main board uses Alpha mimic but I don't want to go to those lengths or expense.
Would be grateful for any wiring diagrams.

Regards
John
