NOTE
When channel 1, 2, 3 are the input and channel 4, 5, 6 the output:
Channel 1, 2, 3: input side, channel 4, 5, 6: output side
Input: 3V3A, AC mode / output: 3V3A, AC or AC+DC mode
Analog output from the torque meter: to channel A of the 9603
Analog output from the rotation counter: to channel B of the 9603
