I was confused between input channels number and output channels number. If I set input channel number 101, then the output channel is also 101 or others 102. What is the meaning for 101 and 102 for output channels.
For output channels, there are channel number on the left hand side. Then there is command number(s) here. What is the meaning for command number here?
Please help to clarify the relationship between input channel number, output channel number and command number.
