GPIO (General Purpose Input/Output) Connector
You can configure the GPIO pins by using Universal IP (UIP) AT Commands. Refer to the Universal IP (UIP) AT
Command Reference Guide that you can find on the Multi‐Tech website. The following table explains the pins.
Pin Number Description
Pin 1 DIO 0
Pin 2 DIO 1
Pin 3 DIO 2 / ADC 0
Pin 4 DIO 3 / ADC 1
Pin 5 ADC 2
Pin 6 Gnd
You can configure the GPIO pins independent of each other.
●
Pin 1 Digital Input, 24 Volt tolerant.
●
Pin 2 Digital Input, 24 Volt tolerant.
●
You can configure Pin 3 as either Digital Input (5V tolerant TTL/CMOS levels) or Digital Output (3.3V High) or
as an ADC input (0 to 3.3V rail)
●
You can configure Pin 4 as either Digital Input (5V tolerant TTL/CMOS levels) or Digital Output (3.3V High) or
as an ADC input (0 to 3.3V rail)
●
Pin 5 is configured as an ADC input (0 to 3.3V rail)
●
Pin 6 is GND and must be connected to the ground of the attached device
