switches. The following sections describe the switches.
GPIO Switch Bank 1, SW3
GPIO Switch Bank 1, labeled SW3, is a set of five slide switches that allows the 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
User Push Button 1, SW1
When switch number 1 is set to GPIO-1, pushing User Push Button 1, SW1, will drive GPIO-1 (Wi-
ME pin 7, ME pin 12) low.
