I have just acquired a OO Bachmann class 37 loco fitted with a Hornby 21 pin decoder. CV 7 reveals it to be version 134. Is this a a TTS decoder? I am using a Bachmann dynamis controller. I need to balance the volume levels on some of the functions by changing the values of CVs. Where can I get the list of CV addresses for this decoder? Are all decoder CV addresses the same? i.e NRM standard Also, I cannot read CV 2. (Start voltage" I just get the message "error on reading" is this normal for this decoder?
