NOTE 1:
The instrument does not internally contain a bus termination resistor, per SAE-J1939
specification. See Understanding Data-Bus Operation section for additional information.
NOTE 2:
Of the six available inputs, five (1 to 5) can be configured to read voltage, resistance, frequency
and digital inputs (LOW/HIGH). One input (6) is dedicated to read current, ideal for 4-20mA sensors.
See Appendix C section for additional information.
Only available for maxAI430v model
