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). FOX3-2G/3G/4G Series Hardware Manual 32
