  1. You need to change the software that you are using as decent software will not change any turnouts in the situation where the from of a train has lost some of the rear.
  2. I’m afraid you are wrong. CV5 does not control the top volts, it controls the duty cycle proving an apparently lower voltage but the top volts remains the same.
  3. Just do the rear most axle of the last wagon
  4. Reducing or altering CV5 doesn't reduce the actual voltage that is applied to the motor, what it does is affect the duty cycle of the pulse signal this reducing the average or apparent voltage to the motor. If the track voltage is 15v at CV5=252 then the peaks will still be 15v (less decoder internal losses) however if you reduce CV5 to 126 then because you have reduced the duty cycle by 50% then the average voltage will be ~7-8v. CV57 on Zimo decoders reduces the actual voltage that the decoder outputs in 1/10 of a volt. If you want a max 6v you would set CV57=60 and the max voltage would be 6v. If you leave it at CV57=0 then it will output whatever is put in, meaning if your track voltage is 15v then you will get out 15v (less decoder internal losses)
  5. I wonder if you have 1 x DR4088CS-LN and 2 x DR4088CS? the DR4088CS connect through the S88 bus to the first 1 x DR4088CS-LN and you set them up as described in the manual EDIT - This video might help you as I think it may be what you have. digikeijs dr4088 setup
  6. Cv5 sets the maximum speed for the loco and you should set this to be representative of the prototype loco - you don’t want to model hurtling along at 250mph! once you have the max speed set then play with CV6 to get the sort of response that you want.
  7. You should get a number from CV8 rather than a name and for Bachmann it is 101. NMRA Manufacturer IDs
  8. Depending on which Bachmann it is, it may alreday by a Zimo decoder Look at CV6 which should be set around 2/3 of CV5 for a linear speed profile, play around with it to make the 'curve' appear more like you want it to be. Lowering the value shoould make the acceleration from stop to mid-speed slower, raising it should make the acceleration to mid speed faster
  9. The max value given for cv5 max in the previous post is incorrect. The default Max speed setting for Zimo in cv5 is 1 which will be translated as 252. You can reduce the value from 252 to slow the loco. If you reset the loco using cv8=8 then you get the default values for all CVs, but they are also listed in the link. edit - should have also said that cv57 can be used to set the max voltage for the motor, thus limiting top speed.
  10. You need to tell EACH DR4088xx the start address and how many feedbacks that are in the unit. Ergo, for the first unit, you put it in programme mode and send an address of 1 (this is a turnout address). This means it starts at 1, you then need to tell it to use the next 16 addresses consecutively. Doing this defines addresses 1-16 in this unit. For the second unit you need to start at 17 - you have already used 16 addresses, therefore the first number you send is 17 followed by 16 which means you have programmed the second unit addresses from 17-32. rinse and repeat for additional modules does this make sense?
  11. I suggest that you re-address the DR4088LN starting at 1 with 16 contacts, then 17 with 16 contacts for the next box, then 33 with 16 contacts ...
  12. I assume that as you have the 4088LN that you are not using the S88 bus? If you are using a DR5000 (which I think you are) have you deleted the S88 feedbacks in the configuration for the DR5000? IIRC it always adds at least 1 x S88 module and you need 0.
  13. Do the answers provided not give you some indication of what people think?
  14. Cv29 does not alter the voltage that is output by the decoder. Some decoders, e.g. Zimo do allow you to set the maximum voltage using CV57 but I don’t know if LAIS support this. A Zimo MX617 has an average current rating of 0.8A with a peak of 1.5A and will provide much better control than a LAIS decoder - it is only £20 plus postage.
