[Range selection]
The following table shows how to set the range of SM231 8AI with DIP switch. Use 3, 4 and 5 to select the analogy input range, use 1 and 2 to select current input mode(ON means current input mode for channel 6, OFF means voltage mode), for switch 2, ON means current input mode for
channel 7, OFF means voltage mode.Attention: The unused DIP switch SW4 ~ SW6 must be set to OFF.
