david_denham Posted August 25, 2016 Share Posted August 25, 2016 Here we go Using railmaster and e link Locos dapol class 22 x 2 Bachmann Branchline 36-557 21-pin E-Z Command 4-function 1A decoder with back EMF Programming track brand new cleaned Brand new wiring checked Programming checked with 5 different locos and ten chips all work fine Locos class 22 been sent to somebody else and tested (Roger thank you) They work on track under 003 both Put them on programming track CANNOT read chips in either locos they worked at Rogers but they did not work before I sent them They all return a read of 255 Track is spotless Wheels are to What's wrong ? Anymore info needed please ask so I can resolve this Link to comment Share on other sites More sharing options...
Chrissaf Posted August 25, 2016 Share Posted August 25, 2016 The only other thing that you can try, is to disconnect your track output of your eLink whilst trying to read the CVs on your separate programming track. My Loksound V4 decoders return ALL 255 values when being read on my programming track, but read OK if I disconnect my main track output. I use Elite, not eLink but the same workaround may apply.

HornbyRailMasterSupport Posted August 25, 2016 Share Posted August 25, 2016 Also check to ensure that the power clip to your programming track does not have a capacitor fitted across its terminals (beneath the plastic cover). If so just clip it out as the capacitor will interfere with DCC programming signals. Link to comment Share on other sites More sharing options...

poliss Posted August 25, 2016 Share Posted August 25, 2016 Reset the controller and decoder. Link to comment Share on other sites More sharing options...
david_denham Posted August 26, 2016 Author Share Posted August 26, 2016 Reset the controller and decoder.Done this by the little red square in the stop button twice tried five new decoders in two locos all of which read ok in other locos Link to comment Share on other sites More sharing options...
HornbyRailMasterSupport Posted August 26, 2016 Share Posted August 26, 2016 Try resetting the locomotive decoder itself by writing the value 8 to CV8 in the loco programming screen. This will then default the loco to ID 3 once more and you can try again from there. Link to comment Share on other sites More sharing options...
96RAF Posted August 26, 2016 Share Posted August 26, 2016 Hornby had problems with certain Baccy decoders in the past with Select and Elite controllers, which was sorted by updating the firmware. I wonder if there is a similar glitch in the eLink firmware. Link to comment Share on other sites More sharing options...
david_denham Posted August 26, 2016 Author Share Posted August 26, 2016 Ok decided on a workaround for nowputting the decoders bother locos setting them all up for the dapol class 22s then relocating them back into the 22sits a short term fix to a problem I can't resolvethank you for your help Link to comment Share on other sites More sharing options...
Terry_Vincent Posted August 27, 2016 Share Posted August 27, 2016 Hi David, just a thought, do your 22's have supression capacitors and/or inductors fitted ? If so you could try removing them as they are not required when fitted with DCC chips and can often interfere with programming. Link to comment Share on other sites More sharing options...

One way to firmly prove this is using a decoder setup rig such as the ESU one or make your own as shown in my linked projects area. Link to comment Share on other sites More sharing options...
Fishmanoz Posted August 27, 2016 Share Posted August 27, 2016 Rob, separate test rig is the elegant test method, but effectively he has used one, it being the other loco in which the programming works. Link to comment Share on other sites More sharing options...

david_denham Posted August 29, 2016 Author Share Posted August 29, 2016 have ordered a lenz decoder to try just to see if its the combination of the three Link to comment Share on other sites More sharing options...
david_denham Posted August 31, 2016 Author Share Posted August 31, 2016 A final update on thiseverything stayed the same except I changed from a bachmann decode to a Lenz 21+ silver and everything is perfect reads writes works no problem at allso my conclusion is there is a problem betweenbachmann decoder e-link and dapol Link to comment Share on other sites More sharing options...
