Digital Port Functions Appendix BSeries E4360 User’s Guide 97Bi-directional Digital I/OEach of the seven pins can be configured as general-purpose bi-directional digital inputs and outputs. The polarity of the pins can also beconfigured. Pin 8 is the signal common for the digital I/O pins. Data isprogrammed according to the following bit assignments:Pin 7 6 5 4 3 2 1Bit 6(msb)5 4 3 2 1 0(lsb)To configure the pins for digital I/O:Front Panel: SCPI Command:SelectSystem\IO\DigPort\Pin,where is the pin number.Select Function, then Digital I/O.Go back one level, select Polarity,then either Positive or Negative.To send data to the pins, selectSystem\IO\DigPort\Data.Select the Data Out field andenter the binary word.To configure the pin function:DIG:PIN<1-7>:FUNC DIOTo configure pin polarity:DIG:PIN<1-7>:POL To send data to the pins:DIG:OUTP:DATA The digital I/O pin can be used to control both relay circuits as well asdigital interface circuits.
