GCA145 with DDX

Postby Esteban » 25.12.2012, 16:51

Hi rocrailers,

Merry Christmas to everyone.

I wonder if you could tell me if it is possible to connect the module GCA145 (fiddle yard) with the Central ORD-1 (DDX) to control the fiddle yard with rocrail. In that case, how can I do that?

I appreciate any help.

Regards

Hello Esteban,

Merry Christmas to you too.

The GCA145 uses contacts from switch/turnout/accessory decoders to get the wanted track address and sensor/feedback contacts to signal bridge in position and bridge occupancy state. In theory it will work with any accessory decoder and feedback detector that works with DDX.
If you look at this page of the wiki: http://wiki.rocrail.net/doku.php?id=mgv145-en#interface_to_gca50_and_can-gc2 you will find the different signals, pos write b0-b5 and write are to be connected to 7 accessory decoder outputs, pos match and feedback 1-4 (it is up to you how many detection sections you divede the bridge into, 1 is minimum, 2 is recommended) are to connected to feedback inputs.
Best regards, Viele Grüsse, vriendelijke groeten, Ronald :rr_cap:

Hello Ronald,

Thank you so much for your answer.

When I read the wiki, I got the idea that I could do it this way,
but I wasn`t completely sure I understood it well, due to my basic level of English.
Now, and after I've read your comment, I'm sure about it, so lets do it!

If during the assembly process of my GCA145 I've some doubt, I will ask for your help again.

Thanks again and best regards

Esteban Martín

Hello Esteban,

You're welcome (Deneda I believe in Spanish). Keep in mind that the GCA145 inputs (outputs from the accessory decoder) require DC (some decoders like Lenz LS150 have an AC output) and may need some resistor to reduce the voltage level to smoewhere around 5V.

Hello Ronald,

Thank you for letting me know this detail, I didn't know it. I will keep in mind.

P.D. "You're welcome" is "De nada" :D

It will be possible to use CGA145 / 146 without any loconet system.
Using the new interface to send DCC comands through J5? To command it?

Sure! It's possible.
The easiest solution is to use GCA174, programmed with DCC software.
From the same provider as GCA145 & GCA146 (P. Giling).

Or an ordinary signal DCC decoder dully connected at J5 socket also.
Have you already tried?
