GPIO (General Purpose Input/Output) 6-Pin
Connector
The GPIO pins are configured using Universal IP (UIP) AT Commands. Refer to the Universal IP (UIP) AT Command Reference
Guide on your MultiModem CD. The following table explains the GPIO functions:
The GPIO pins can be configured independent of each other. An explanation of the difference between the Rev B and Rev C
boards is provided in the Back Panel description in Chapter 1.
