The digital I/O pin can be used to control both relay circuits as well as digital interface circuits. The
following figure illustrates typical relay circuits as well as digital interface circuit connections using the
digital I/O functions
To configure the pins for digital I/O:

DIG:PIN2:FUNC DIO
DIG:PIN3:FUNC DIO
DIG:PIN4:FUNC DIO
DIG:PIN5:FUNC DIO
DIG:PIN6:FUNC DIO

Digital Input
Each of the seven pins can be configured as digital input only. The polarity of the pins can also be
configured. Pin 8 is the signal common for the digital input pins. The pin status reflects the true
condition of the external signal that is applied to the pin. The pin state is not affected by the setting of
DIGital:OUTPut:DATA.
To configure the pins for digital input only:
