I have just received my One Servo Decoder - thanks!
I can't program it using my NCE PowerCab DCC system and with the decoder connected to the rails.
I have tried many things but the servo either does not move, or it creeps round very, very slowly, or it spins round many times very, very quickly. I have tried 3 different servos with the same result.
Your instructions refer to the "+", "-", "Left" and "Right" keys. The PowerCab doesn't have any of these keys.
Can you tell me the sequence to set up my servo for accessory address 1005, 90 degree travel and speed 18 (i.e. quite fast) please?
