CN6
AI2 analogue input channel can select voltage or current signal.
When pin 1 and pin 2 of the CN6 are short-circuited, AI2 channel
inputs voltage signal;
When pin 2 and pin 3 of the CN6 are short-circuited, AI2 channel
inputs current signal.
CN7
AO1 analogue output channel can select voltage or current signal.
When pin 1 and pin 2 of the CN7 are short-circuited, AO1 channel
outputs voltage signal;
When pin 2 and pin 3 of the CN7 are short-circuited, AO1 channel
outputs current signal.
CN8
AO2 analogue output channel can select voltage or current signal.
When pin 1 and pin 2 of the CN8 are short-circuited, AO2 channel
outputs voltage signal;
When pin 2 and pin 3 of the CN8 are short-circuited, AO2 channel
outputs current signal.
CN9
SCI communication can select proper resistance.
When pin 2 and pin 3 of the CN9 are short-circuited, no resistance;
When pin 1 and pin 2 of the CN9 are short-circuited, select the proper
resistance.
