Hi chaps , the replacement Z21 landed an hour ago and boom 💥
we can read chips , we can see numbers and we get movement and clicks from the Z21 when you press read on the apps.
Firstly I tried a simple Bachman chip I knew was set to 3 and it read it fine
them tried a sound chip I knew the address of and again fine
tried the sound chip giving me issues and all I got was 3115 then 255 , initially I managed to get sound from it and was seriously buzzing it worked then silence and all I got was 255 when I tried reading ( googling brought up a suggestion it might need weights or pressure applied so I tried it and we got sound again)
I went into the settings section and can get most things operational now except for the lights
ive tried the chip in 2 locos and the same results, all sounds work , smooth movement forward and backwards but no lights
Just to say a massive thanks for your suggestions and the multimeter proved the last unit was faulty and I wasn’t being stupid and doing something wrong
👊🏻🍺🍺
