solved. issue with compatability between controller/display



Thread 'sw900 error 11' - Version comparison

• hello ive just had a quick search and cant seem to see any other thread with this error.
  
  ive got a sw900 display but its a 6 pin waterproof.
  
  my controller is a 5 pin connector.
  
  ive bought an extenstion for the display and ive connected it up with a 5 pin on the end but leaving the white one out ( wired exactly the same way as my other e bike display )
  but its coming up with " ERROR 11 "
  
  
  have to mind the bad wiring it looks as its not in the way it is but as its the first time lol please forgive me but this is how it goes as pictured left to right;
  
  red blue black green yellow
  
  
  the controller colours are throwing me off but here is a diagram of whats what.
  
  everything works it runs and stops but like mentioned its coming up with a communication error and not displaying speed, watts or anything like that.
  
  
  i have tried a combo of wire options and either gives E10 or E11

Keep in mind that if the controller was not previously working with this same model and version of display, it's uncommon for displays and controllers to be generally intercompatible. If they aren't compatible, the display will power up and turn on, but it can't communicate with the controller (a poor analogy is they dont' speak the same "language") and vice-versa. So the display will not display any data other than (sometimes) battery level or voltage, and the assist-level-change buttons don't work, etc. The power button and light button usually work.


E-HP has a thread regarding display compatiblity that may help find a compatible one if necessary.
