set up in combination with Fleischmann twincentre

[maurits71]

Hi All

I have tried to get my decoder working in combination with my Fleischman Twincentre.

this is what I have done sofar.

Firstly have connected the decoder to the program track of my fleischmann twincentre. Was able to read and write cv’s



Have changed cv29 to 192 and cv 1 to 12 ( is virtual address 45, 46,47,48 ). Left cv 38 to 0. Common of a signal in a ( as I have common anode signals ) and green in a and red in B



Both lights come on. But won’t switch if I push address 45, or 46,47 or 48



After that did try to change any cv’s settings but the unit gives a fault now ?


have contact Paul from CRsignals who suggested me to program the adress using the jumper. so power off, fit the pgm jumper to 1 and 2 of J5. power back on. push adress 45 forward and back ward, power off , remove jumper, but still no joy.

Have tried to reset the unit with cv 8 = 8 but again a fault

( if I have this message on my loco's it normally means short cut or decoder fault. )

any tips / advise ?

Thanks a lot Maurits

Setting CV29 to 192 and CV1 to 12 should have been responding to addresses 12, 13, 14 and 15 or 8, 9, 10 and 11 (I do not have a twincentre to tell which). To respond to 45-48 would require CV1=11 or CV1=12 and CV29=128.

Using the jumper method as Paul has suggested is the best way to set the address because it will set CV29, CV1 and CV9 automatically.

If you have removed the jumper and programed CV8 to a different value to force a factory reset there is nothing more to try, that should get you out of any configuration problem so that you can start again.

It is normal for both LEDs to be on initially when using common anode LEDs wired as you have done unless you change CV35 to 255 to invert the polarity of the LEDs which will allow you to put the Red one on terminal 'A' and the Green one on terminal 'B'. Additionally you can change CV37 to 170 or 85 if you just want the Red LEDs or Green LEDs on at reset.

Many thanks for the answer Paul

I have had another try this afternoon, unfortunately the unit isn't responding to any cv reading, have tried various ways, connected to the program track, directed direct to the dcc signal. in all cases message is fault.

I have tried both a normal signal and a common anode signal, even tried all addresses possibly ( quit a challenge I must say )so I am afraid that this one is faulty, as from experience a fault in a cv reading means a dead decoder.

Am I right, are there any more things I can do ?

best regards

Regardless of whether you can read a CV or not, have you tried writing to CV8?

As a last test try writing 8 to CV8, and 2 to CV1, (ignore any errors) then see if you get anything to happen on accessory addresses 1-4. If you have a voltmeter measure the voltage between the a and k terminals when the track terminals are connected to a power source (12V DC, 16V AC or a track supply).

Also worth noting that if you have access to a Sprog II, the Signalist SC1 is a recognised decoder within Decoder Pro, which makes setting the SC1 even easier.

Thanks for the help Paul and Paul

Have tried to write 8 to cv 8 and 2 to cv 1 without any joy. I haven't got a volt meter by hand but when I connect a signal or a common anode signal they show a light or 2 in the case of the c.a. )

as I have been able at he beginning to read and program CV's I still believe that the memory unit is faulty at the end this isn't the first decoder I program ( although the SC1 is my first one ) I think with over 40 points, 30 or so digital trains I have a bit of experience with decoders and accessories.

Maurits,
Please post the decoder back to me and I will check it out and replace as necessary by return post.

Thanks Paul I will do, I see lots of benefits with this decoder comparing to the ones I am using now, but most important now is that I can get it to work with the TC first, which is also in the benefit of fellow users.
