Description:

The module has 8 digital I/Os; 4 configurable GPIOs, 1 input-only, and 3 output-only.

The module also has 3 ADCs, and 1 DAC. All of these signals are controlled by the AT*E2IO command.

Note! IO1 to IO4 are set to INPUT as a factory default. Their status (Input/ Output) is stored in non-volatile memory.

Set command controls the operations with the I/O signals for the M2M devices. It is possible to perform up to 5 operations. These operations have the following meaning:

•Read (<op> = 0): It reads the state of the specified signal. It returns the binary state of digital signals or value (0-255) of an ADC input or the DAC output. In case of a digital I/O the command has the following syntax:

AT*E2IO=0,“IO1” *E2IO: 0,“IO1”,0

OK

If reading from the ADC/DACs:

AT*E2IO=0,“AD1” *E2IO: 0,“AD1”,,62

OK
