  1. I am converting a Lima Deltic to the Porterbrook spec version. I need some information on the WIPAC light clusters fitted. I need dimensions and layout wrt the lamps colours and usage. Appreciate any help that you can give Bill
  2. It was the socket. I have replaced the socket with a new one on the homebrew breakout board I fitted and everything is now working as expected. Thank you for your assistance. I wasn't sure how the software was supposed to operate which slowed me down a bit!
  3. Thanks Melmerby that is basically how it is set up got to be something simple I'm missing. 34theletterbetweenB&D: I suspect that you are on to something there, The programming seems right, I have had a few problems with the socket so it could well be open circuit Next thing to check!
  4. That is the problem, The wiring is correct, I have been doing electronic projects with wiring far more complex than this for a very long time, I just can't get any of the lights to turn on. Motor control is fully functional so obviously I'm missing something. The options for lighting in the Lenz decoder in JMRI include "No effect, MARS light, GYRA light, strobe and double strobe" I have to make the assumption that, in this instance, No effect means that there is no alteration to the light operation, it is on or off depending on F0. Am I correct in this?
  5. Using a DCC++ controller and JMRI software. I can read the decoder on the programming track and I can program the decoder on the program track no issues I have set up speed tables and all the motor functions no problem. However, I just can't seem to get the lighting to work. I have wired the LEDs to the correct outputs from the decoder. I have a problem with the actual meanings of the options in the lighting control page as I can't find "an älways on" option that would operate the forward a rear facing headlights. An idiots guide to programming would be appreciated! if anyone can oblige? Many thanks Bill
  6. Cracked it! the NEM socket was faulty! it was preventing the plug from seating fully. Sorted that out and all running well again. Must have been pure luck that it ran for the last couple of weeks only stopped when I unplugged the decoder to tidy the wiring! Always the last thing you touch! Thanks for the assist
  7. I recently fitted a Lenz standard Plus V2 decoder to a Lima Deltic model. All went well until yesterday when it refused to move at all. I am running a DCC++ system based on an Arduino Mega 2560 clone and motor board, using JMRI as the control interface. I have put an oscilloscope on the track and the signals appear to be present, I have a peak to peak voltage of approximately 14 v square wave at about 8kHz. pulse modulation can be seen taking place when commands are sent to the track. The carriages I have with lighting are all illuminated normally so power seems to be getting to the track. I removed the decoder and bridged the track pickups directly to the motor connections and ran the track on DC and the motor operated as expected in both directions with no problem. With the decoder in place and on the programming track When I try to access the CVs I get the error message "No acknowledge from locomotive (308)" and read data returns "Unknown" I have change out the Mega 2560 for a brand new unit, and likewise for the motor board. This has had no effect on the problem. As I am building all this from scratch I have no other loco fitted with a decoder to compare results. It looks to me like the decoder has failed, I have read that it is possible that the decoder can "lock up" and needs to be reset, and I have the data for that reset process, but JMRI will not allow me to access the CV responsible. So the questions are:- How exactly do I send a reset code to the decoder from JMRI? Is it likely that the decoder has failed? Have I missed something obvious? Thanks for your assistance in advance
  8. Excuse me for butting in here, I have a question bout the wheel sizes used on the Siphon G bogies. I have a drawing of the 0.11 version which shows 9'bogie centres but no detail of the bogie or wheel size. Scaling from the drawing (a bad idea, I know) I get a wheel size of bout 3'9". I expected 3'6". could anyone advise me of the size of the wheels please?
  9. Unfortunately it appears to have lulled me into a false sense of security and it failed again. I am now using a Geekcreit Mega 2560 board and that is working fine. Seems that the Geekcreit Uno is not compatible.
  10. OK good news, after trying on another computer with the same results I changed out the Geekcreit UNO board for a spare and now it is working fine. It appears there may be a faulty UART on the bad board which is failing during the constant transmission of data to and from the JMRI software. Happy bunny!
  11. G'day, I have assembled a Geekcreit (Chinese Clone of a UNO) and an Arduino motor shield. I have downloaded base station V 1 from Github and loaded it into the Uno. I have downloaded the latest version of JMRI from their website and installed it. I have Engine Driver running on my Android phone. There is never a communications problem between JMRI and Engine Driver. JMRI is running on a Lenovo ideapad 100S with Intel Pentium N3710 processor running at 1.6GHz, 4Mb RAM, under Windows 10 Home, build 1909, Screen saver disabled. It all runs perfectly well for about half an hour to 45 minutes and then the JMRI software seems to stop communicating with the UNO and the trains carry on running a per the last instruction sent. There might be a correlation between computer idle time and failure but that is not consistent. The JMRI log indicates that there has been a timeout error when the failure occurs I am using a single loco with a Lenz Standard + V2 decoder. Current drain is around 130-150mA at 12 volt supply to the motor board when driving the train and around 40mA idle, no components seem to be getting hot - not even warm in use. Current drain drops to 0 when the track output is switched off. The baud rate is set in JMRI to 115200 and greyed out and I have set my COM4 port (USB connection) to the same baud rate, 8 data bits, no parity, 1 stop bit. I suspected my cheap USB cable but changing that out made no difference. Anyone have any ideas?
  12. One final question before I wrap this up. Did all of the sorting vans have bag handling equipment or are there some vans which only had sorting facilities?
  13. Thanks gents, being new to this could someone explain the meaning of the brake van numbers and PO coach numbers. Are these actual serial numbers or are they diagram numbers? Another question PO coach is obviously a type of coach, how did it differ from a regular coach? are these the ones with mail catchers?
  14. Thank you gents a great help. This begs another question, what about headlights? I see some of the later arrangements have two white lights (well tungsten) one each side of the headcode but there does not appear to be a headlight fitted to these engines at this stage of their life. I have seen one with the small yellow panel at each end featuring a box on the front, just above buffer height and on the left of centre when viewing from the front, is this the 'Wipac' headlight I keep reading about? If so when was this used? And does this mean that initially the locos ran with the driver unable to see the track ahead when it was dark? At this time were they attaching a lantern to the front end on the clip above the buffer? appreciate your assistance
