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).
