OK guys, here's a forum for DCC users. Input is needed, tips, questions, problems, and general ranting (within reason). I know several devotees of digital control so if there's something that needs an answer, it can probably be found. Let's get after it!

Dear Woodie,
Ok, Don here, I've just signed up. I have two problems with a ROCO 10674 system where, firstly, sometimes the red overload light comes on, with nothing connected; and secondly, after the multiMAUS boots up, it says Error 13 - No X-PressNet master found and states there is a communications problem... ???

I searched for the relevant data and found that DCC is based on a slower version of RS-485 and there was a connection diagram, where (on the pins of the RJ11 plug)pin 2 was supply ground, pin 3 was RS-485 -ve, pin 4 was RS-485 +ve and pin 5 was supply +ve.


As the cable between the controller and the box, and the track cable, were not supplied (and still haven't been) I made up a RJ11 to RJ11 cable (I am a licensed Cabler according to ACMA in Australia) and got the controller to light up and boot but no comms.
Has anyone had this problem???
Don

Howdy Don...welcome to the forum, you will find lots of help here, but not from me. If it requires more than 2 wires, I am stumped! It does sound like a fault with the power supply since it overloads with nothing connected. I would contact the manufacturer about this. Otherwise, have fun and if you can...run a train today!

OK, Woodie, Thanks
Maybe some others may have come across this...
