7.1.3.5. Serial Port 0 - Serial communication signals (RxA and TxA)
FOX3-2G/3G/4G devices incorporates a full duplex serial channel which allows two devices to communicate directly
with each other via the RS232 serial port. All supported variable baud rates are software-controlled. It is
recommended to use the FOX3-2G/3G/4G Evalboard in order to communicate with the FOX3-2G/3G/4G devices, since
you will find there all you need to evaluate with it. The signals on these pins are obtained to RS232 compatible signal
levels.
RxA_0 Main channel used to receive software commands to the board from any
software (e.g. HyperTerminal). Moreover, the firmware update can also be done
through this serial port.
TxA_0 Main channel used to output navigation, measurement, response and system
data to any software (e.g. HyperTerminal, Workbench).
