  1. I am totally stunned, many visits to Smithdown Road and the help given will always be remembered and treasured. Thank you Hattons for all the help and assistance going back to the 1960’s, I just hope everyone from Hattons manages to survive this terrible event and move on successfully. 🤞🤞

    Thank you for the reply, it’s greatly appreciated. 
     

    I have just clicked on the link and looked at it and I can’t find anywhere where it says what condition it is being produced in. 
     

    Any help is greatly appreciated. 
     

    Thank you in advance. 
     

    Kind Regards, 

     

    Danny. 

    The photo in the supplied link shows it in preserved unnamed condition with current warning flashes. Sadly no longer available to order……

    Further to my above post, prior to fitting the Lais 860019 I installed it temporarily in another loco for the purpose of re-setting CV1 - the decoder ID. I did not check or change any of the function outputs prior to its now successful installation in Caroline.

    With the  hindsight provided by other subsequent posts taking a note of the values of other CVs would be sensible.

     

    Two queries remain.

    1. Is the switching on/off of the train end lights without any resort to blanking tape a unique function of the ZTC controller?

    2. Is there a simple way of adding a resistor to the PCB to mimic a motor load so that were the decoder to default to ID3 (as some decoders unhepfully do on odd occasions ) then CV1 could be reset without having to remove the body and risk all those delicate fittings? I'm sure all the forensic c investigations of the PCB will produce some useful output.

    Hi Andy, I’ve found that you are able to amend CV’s on the decoder whilst in Caroline but you cannot read them back hence making a note of the existing CV’s from a reader or slave loco before doing any changes. If you get stuck you can write 4 to CV8 to reset the Lais decoder.
    I’m rapidly coming round to having to make an additional custom pcb board with a sound decoder/speaker to get everything working correctly and have just horn sounds without any conflict with the loco sound functions.

    Hope this helps 🤞

    Finally got around to putting a decoder in mine, the LAIS 860019. When I put the coach on the track all of the lights come on (except the trailing reds). I can't get any of the functions to work to operate the lights and the NCE handset says it cant find the decoder if I try to interrogate it.

    Anyone else had this? What am I missing? Is this decoder no good for this coach?

     

    Cheers

    Unfortunately you cannot interrogate a decoder in Caroline as it is in a no load installation ie no motor. I used my ESU Decoder Tester to read and program the 860019 (you could also use a dcc loco as a slave). You can re-write cv’s to the decoder but make sure you know original value’s first so you can revert if needed.

    Forgive the hand-drawn untidy efforts, but here's how the boards work. Intriguingly the SMD resistors marked 810 all seemed to measure 1K on my multimeter!

    That’s very interesting about the resistance values and also the complexity on the pcb. I had already tried checking the outputs on dc and dcc and had some unstable results. I’m now thinking I may have to make up a pcb to work with my planned direction LED’s indicator display on the NSE version. Thanks for letting us know your findings, it’s certainly given me food for thought!

    Having just Googled the product name to findout what was meant by EOT, these appear to be modern BR style tail lamps. There are no EOT devices like in the US in use in the UK, over here we only have tail lamps.

     

    In the BR era, I don't think you'd need a lamp as Southern Region stock was permitted to run with the blinds wound round to red, as shown here on this Flickr link

    That might save you a job and save a tail lamp for another project.

    Thanks for your reply. You are correct about southern region directional lighting. I’m only intending to use a tail lamp on the green version as I believe the screen should ideally be changed from reading an alpha numeric route indicator to red panels when direction is changed, not really practical in 4mm. With the NSE version I’m toying with the idea of bi-colour red/clear LED’s behind a black and white paper panel thus showing white being propelled and red when being towed.

    Is this without circuit board mods/tape?

     

    I didn't bother to see if I could separate out the 4 lights (front red/white rear red/white) using the decoder as I assumed they were hard wired to work for DC.

    My only physical mod is tape over the loco end contacts on the circuit board. On dcc the direction switch on a controller just changes the head/tail lights over at both ends, sadly they have no independent control that I can find.

    Has anyone traced the circuit board? I might give it a go and see how easy it is to "tweak" the circuit to operate the ends separately.... I'm using a Loksound FX which has a multitude of extra functions so worst case I can tape the contacts and "wire" one end directly to other functions. I'll let people know how I get on....

    Further to my previous post referencing rear red light when Caroline is being pulled. I have changed my setting using F5 (cv 36=64) to cv36=2 which has moved the red light effectively to F0 cv34. The lights now operate correctly just using just the direction control. 
    My reason for this was trying to stop loco sound functions and Caroline light function conflicting. Rear lights F5 on Caroline and loco F5 was a no load situation on the loco which means you have to manually notch up to increase the engine sounds. With the latest settings I’ve set up an Advanced Consist and it works without any issues. I also tried using the same address for both loco and Caroline and that also works well. The only issue is that step lights F3 also gives a short horn blast and tunnel lights F4 gives a long horn blast, not a real concern for me but maybe for some of you.

     

    My next challenge is to fit DCC Concepts EOT red lights on the blue/grey and NSE versions, I really need to work out the end contacts on the circuit board. I’ve tried an AVO but didn’t get consistent readings on either dc or dcc. Has anyone worked out what the connections U+   U1+    F    R  and  Q5 actually relate to please? Great fun!

    i'm using a lais decoder and i think all lights are working, is their a complete list of light functions and what output they are on/f number?

     

    i need to figure out how to remap function 2 to another so its locking (for the rear lights when been pulled)

    I used this table to make changes to the Lais decoder. Hope it helps.

    That's usually the decoder that I would use for most of my 21-PIN fitted locos, but they've been out of stock pretty much everywhere for quite a while now, so i've been using the Dapol Imperiums instead.

     

    Btw, has anyone had any luck programming the decoder whilst in Caroline, or have you had to put it in a loco to program it. I'm looking at using JMRI to program mine, so wonder if that would make a difference?

    I’m sure that you cannot read or write to the decoder in Caroline as a decoder needs a load ie motor during programming. I did all my programming in a ESU LokProgrammer.

  11. I have been having some 'fun' trying to setting up the lighting CV's on my Carolines!

    Based on earlier recommendations I tried the Laisdcc 860019 decoders but found that while propelling was OK lighting wise (once CV29 was re-programmed to 7) towing was an issue as the lighting functions are not good. Problem 1 is that red tail lights are set to F2 which unfortunately is non latching on my Prodigy 2 so they only show if you keep F2 pressed! Problem 2 is that red tail lights only work with F0 enabled so front lights next to loco are also on!

    I have resolved these issues in two ways, I swapped the F1 and F2 function keys over by swapping CV 35 and 36 values (I'm not a lover of internal lighting so no problem for me) so F1 now operates the red tail lights. I sorted the front lighting at the loco end by carefully removing the circuit board in the roof and covering the 5 contacts at the loco end with a strip of Kapton tape = no lighting functions.

    It's not an ideal situation having to do this on what is after all a very expensive coach.

    If any others have approached this issue in another way please let us all know.

     

  12. The ‘what could have been’ BR liveried pair have received my EOI - brilliant! Definitely need some 04’s with skirts if / when they are produced. As a 5 year old I can definitely remember the sights and sounds of the W&U, imagine if the line had lasted long enough to be preserved.
