Addressing Cobolt decoder ADS-2fx

[DavidT]

Hi all, having problems addressing Cobolt decoders  using Railmaster? have tried deleting and reinstalled turnout on track plan but still cannot get it to address? have tried replacing with another , same issue will not address,  is there anyway of checking decoder for faults apart from changing and trying another decoder. I am addressing as per DCC instructions for screen based systems.

Thanks for any help.

Are you switching each port to learn mode then clicking the point button on your layout diagram then switching it back to operational?

Thanks Ray , i assume you mean to use learn mode on the on screen display and not the track diagram?

Thanks

No David. On the ADS2FX decoder, there are two ports i.e. 2 sets of electronics, and each one has a "learn" switch - a slider type switch. The instructions on the packaging will tell you which is the learn position. So, move one of these switches to the learn position. Then on the Raimaster screen, click the button for that point. Then switch the decoder switch back to operational. Then go back to the Railmaster screen. Alternately clicking the green and red buttons should then switch the point back and forth. Then repeat the process for the second port on the decoder.

These are the simplest of decoders to program.  All you do is switch to learn, operate the point you want it to control on the RM screen and switch the decoder switch back to run.  Just as Ray says, it's now done.  They are so simple, chances are you are overthinking it.

Thanks for this instruction, have done as suggested but still cannot get points to operate, should i be checking other issues? The RM screen does show the point switching ie, the grey inner line on screen at point does move but point doesnt move physically? 

Thanks for contiued assistance.

quite often point motors get screwed down too tightly. I test each point motor, loose on layout before i attempt to fix. That way i know it works. john

Hi David,

What kind of point motors are you using? Make sure the three wires from the point motor are going to the correct terminals on the decoder - i.e. the common return should go to the centre of the three terminals on the decoder. Also, provided you have the two DCC wires connected to the decoder, then you can test the decoder-to-point operation using the three terminals marked "Momentary". You can do it with a piece of wire in a U shape. Touch the two legs of the U against the left and centre of the Momentary terminals and the point should fire. Touch the right and center of the Momentary terminals and the point should fire the other way.

Thank you John, i have checked as suggested and tried the point motor loose still same problem will not switch still not 100% about the decoder working correctly.

Thank you Ray will try this.

Hi Ray, have now tried test using momentary terminal ,still no response at point motor ?

... and the DCC supply is connected to the decoder also?

 

[DavidT]

Yes DCC supply connected.

David

[St1ngr4y]

Have you either .....

a means of testing the point motor independent of the decoder i.e. a 16v ac supply

or

a multimeter to test the outputs marked Solenoid on the decoder

Thanks everyone, have been intouch with DCC concepts who are being very helpful with my problem. So hopfully will get it sorted very soon.
