See the figure titled "Board Layout and Connector Locations:" on page 17 for the location
of the switches. The following sections describe the switches.
GPIO Switch Bank 1, labeled SW3, is a set of five slide switches that allows the Digi
Connect ME embedded module to use either serial signals or GPIO signals to communicate
with a device. With the switch to the left position, the module’s signal is connected to the
Serial Port1 RS232 transceiver. In the right position, the module signal is connected to the
appropriate pin of the GPIO Port P7.
GPIO Switch Bank 1 Settings
When switch number 1 is set to GPIO-1, pushing User Push Button 1, SW1, will drive
GPIO-1 (module pin 13) low.
Pushing User Push Button 2, SW2, will drive module pin 18 low.
