Hallo,

Sorry not to speak German here, my school lessons are seit lang vergessen

I've read several posts here, found many info about CAN wiring, spent a few days searching for a way to route the Mobile Station 2 orders into another cable.

To make the long story short: instead of plugging the MS to the Gleisbox, which will be somewhere in the layout, I'd like to connect it on the control board, and foward the MS connections through the control board cable (for instance a SUB-D-25 cable, using Floodland's module connectors).



I found the wiring here and there, etc, but
- I still don't know if the MS and/or the Gleisbox require at least one MS to be connected directly at the Gleisbox... as most implementation figure this case
- If not, will the MS be seen as a slave?
- Is there a difference between wiring the 10-pins, or just pins #1/2/4/8 as seen here, §7? Will the MS "sense" the missing wires and therefore become slave?

And last but not least, I'll have to find a 10-pin "b" socket to plug the MS in, at the rear of the control board.
Except on some rare asian e-shops, it seems difficult to find.

thanx a lot!

huh... I just saw Ulli9391's post with pictures from inside the MS.

Seems that the MS2 has only 4 pins connected...?
This may solve the problem a little

Hello RailyRabbit,

i try to answer your questions.

You need only 4 wires to connect the MS2 to the Gleisbox. The Signals are:

CAN High
CAN Low
+
Ground


It is not required that one MS2 to be connected directly at the Gleisbox. You can use a selfbuild Connector.

The Wires have no invluence on Master/Slave. Only the lower Serialnummber of your MS2 is the MASTER MS2. The other MS2 with a higher Serialnummber is the Slave.

For the Connectors and sockets you can ask Thorsten (the Webmaster of this site per Email).

Also you can use the "StartPunkt " http://can-digital-bahn.com/modul.p...#Mod_Top and a cable with 6Pin and 10pin Connector. The Cable is between StartPunkt2 and the Gleisbox.

wow toll!! it's Christmas again!
thanx a lot Michael for your advice!

I was considering StartPunkt at the beginning. But then I'll have to connect 2 cables, 1 for the accessories and another one for the MS2.
Too bad because I really like the use of a single RJ45 cable to carry both signals and power. How can it be simpler??

Right now I'm quite happy if I can rely on a single SUB-D-25 connection, even if it's a little short (i have to trick on the turnouts feedback to save a couple of pins...).
Of course it could be simpler if everything was digital on the layout, maybe later on.
For now, all turnouts & accessories are fully analog.

I also thought of a mux/demux system, but it's a little bit to bold for me right now
(by the way if you know a good tutorial online in english on mux I'm interested)

Thanx again, I'll look after the plugs now ;-)

Many thoughts later...

We agree on the wire to use:
CAN High
CAN Low
+
Ground

Ok.
Is that correct to say that + / Ground are requested to power the Mobile station?
In other way, if I use a power source of my own to power the MS2 (say 12V DC regulated thanks to 7812), can I feed the Gleisbox only with CAN High / CAN Low? (give me 2 more free pin )

This is pure theory for the moment, I guess the Mobile Station eats a lot of power for itself (anybody knows how much?)...
I need to count how much power I'll have to provide!!

thanks
rR

Hallo railRabbit,

der CAN kann theoretisch ohne Masse also nur mit 2 Leitern auskommen. Ich würde aber auf die Masse nicht veszichten.

Wieso aber die vielen Kabel für die Rückmeldungen? Wenn Du den WeichenChef einsetzt, dann hast Du die Rückmeldungen alle auch gleich im CAN und brauchst immer nur die 4 Kabel.

Seit gestern steht im Neuheiten Flyer von Märklin, das die MS2 50mA benötigt.

Schöne Grüße

Hallo Thorsten

At second thought, I think the MS2 require a ground anyway: I doubt it will work with only one pole connected?

I had a look at (almost) all the CDB modules, but we have this fantasy of triggering the turnouts with old-fashioned manual switches, not by using a submenu on the MS2. That's why I'm working on a analog wiring. The only "digital" link whould be between the MS2 and the Gleisbox (and further, to the tracks, to control the loks).

Meanwhile, I came across another idea.
I intend using a regulated 12V DC for accessories. Is this enough to power the MS2? Then I could use the power from the TCO instead wiring the +20V from the Gleisbox.

I shall sketch-up the wiring, but I'm leaving tomorrow for a short ski vacation

thanx anyway and bis bald to catch-up the discussion

Hello railyRabbit,

if you dont like to switch the turnouts by using the submenu on the MS2, you should use the "WeichenKeyboard" and the CAN-Bus. If you switch digital, you have more possibilties in the future..

Have fun on your short ski vacation!
