Thanks for your reply I came to the same conclusion re adding a 2K resistor in series with the decoder + Blue wire. Thanks for the heads up on LAIS products I've now done some research on them.

Thanks Nigel Cliffe, My mistake on CV 65v I got confused it was CV 60 and it did make a difference to my other 2 function wires that are for cab light and fire box. And I do use JMRI Decoder Pro but I find the Swiss mapping confusing I'm OK with the function map. I think I'l just add a half watt 2 k resistor between the decoder blue wire and the Lais resistor board that should do the trick then reset CV 60 so I can see the cab and firebox lights. I've tried to understand the Zimo manual pages 37&38 but just can't get my head around it. Cheers

Zimo MS480 Protodrive sound decoder Hi All, I've got a little problem trying to dim my forward and rear direction LEDs (FO) and I can't find a specific answer on Chat GTP! (or my supplier) it gave me CV 65 for the other function wire green and brown which which are connected to my Firefox glow and Cab light separately. I'm using the white wire for the forward direction lights and the yellow wire for the reverse direction `lights and they work fine but they are so bright. I'm using the LAIS resistor board as you can see in the picture. Each lamp has its own 1K Ohm 1/8W SMD resistors resistor, but they're still very bright. Can anybody point me in the right direction please. The Loco is a Bachmann London Transport 57xx with Digitrains sound file which is amazing. loving the brake function, also installed a sugar cube speaker with 3D resonator plus LAIS stay alive lite 3. Any help would be much appreciated. Cheers.

I found this postcard on the back it's written 0-6-0 No L30. at Olympia. I hope this helps

I think that the Rapido WR16 XX is a fantastic model it runs extremely well until I put a Zimo MS590N18, pre loaded with YouChoose sound file. The main issue is that when I increase the speed above half way the train will not respond to any command or decrease speed after this, it seems locked in and will carry on no matter what I do with the controller, the only way to reset it is to remove it from the tracks or stop the whole system then restart. this has been going on for 2 months now so I decided to take the decoder out and swap it with another zimo non sound decoder. The Rapido runs as expected with a normal Zimo decoder. I have put the Zimo sound decoder into a Bachmann J 72 steam loco with built-in speaker and LED firebox. same problem. I wrote to Rapido who replied with this ; "As far as I have managed to work out, the 16xx is not compatible with Zimo, it was designed to take an ESU decoder and as a result it can behave erratically with Zimo decoders. I understand many Zimo users have removed the PCB and hard wired the model to get it to work. I have sent the decoder back to my supplier here in Australia and he is running tests but so far unable to find fault in the decoder. It looks like I will have to buy a Next 18 Breakout board and remove the Rapido PCB. Keeping my fingers crossed that the new Zimo MS590N18, pre loaded with YouChoose sound file for the J72 will work without a problem. Before you say get an ESU decoder, apparently there is a shortage of them at the moment in Australia.

Hi People. I have just installed my first stay alive on my first sound loco. the loco is a Hornby Black 5 with a Hornby TSS sound decoder, then I added a  Lais Dcc Stay Alive Lite 2. I am impressed with the lot. great loud sound and the stay alive is a total game changer. My next challenge is to instal a LaisDcc Stay Alive Lite 3 onto a TCS DP@x-UK non sound decoder! I have searched the interwebs and this site and emails TCS, to no avail, looking for the rectifier pads to solder onto. My question is does anyone know the correct pads to solder to? Thanks in advance. Stay safe and stay alive

Thanks for everyones help .

Thanks I'll have a look at it. I must say that I find it's all getting very much over complex for me. a comparison that makes sense to me as I'm an electrician is the smart wiring in homes, I did a smart home in Palm beach a few years ago it cost $50,000 for the equipment and caused a lot of problems for the owner who range me and said "I just want to turn a bloody ceiling fan on and now every light in the house is flashing the pool cover is opening and closing as are the garage doors!". I like to keep thing simple cause I'm simple.

Thanks for everyones help and suggestions. I have exhausted the variations in CV 29. so I'm back to the drawing board with my Stay alive units. I'm a very tactile electrician, I have no training in electronics but I am slowly learning. I will as suggested buy a couple of ready made stay alives to prove that they will work on my system, However I get a lot of satisfaction from making things and the cost of 40 RTR stay alives is more than I can afford when I can get 20 Tantalum caps for a few bucks. Many thanks for all the help offered, what a great knowledge bank this is. A work in progress.

Sorry you lost me when you said Assuming, Sadly all this Bit and Byte stuff is not a natural thing for me, it literally makes my brain hurt. Give me a tricky 3 phase 440Volt switchboard to fix and I'm happy.

Brilliant, Thanks for that I'll try 6 in cv29 see if that works. If not I'll use a long stick to prod the locos when they stall on points. Thanks fo your help.

Hi In Wiki DCC Energy Storage it says CV Changes For proper operation, disable the Analog Conversion mode (in CV29), and set the packet timeout value in CV11 to "0." I read that elsewhere too.

Hi Hi I've been told to Disable CV 29 to enable stay alives to work.

Hi knowledgable ones, I'm stuck on trying to get my stay alive's working. I read in a few different places that I have to change value in CV11 to "0." and I managed that, however how do I disable CV 29? but I can't find out how to do that? I've constructed a a couple of different Stay alive's and they hold a charge long enough to keep a 9V LED torch going for a few seconds. The two different Stay alive's are as follows; 8 x 220uf @25volt Tantalum caps in parallel, effectively 1,760uf. connected to TCS T1blue and black stay alive wires. the other is 2x 2,200uf 16volt poly caps in parallel, effectively 4,400uf soldered to blue and black contacts on the decoder socket. My system is Rocco z21 the white one. the track voltage is 17.9 volts. Thats why I really should be using 20 or 25 volt caps. I hope there is a simple answer but I won't hold my breath, I can't really get my head around packets and bits an bytes. With Rocco nothing is easy Touchwood! Cheers in advance

Hi, Did you get any answers to this? I'm trying work out how to disable CV29 and I don't really understand how.
