Serial Port 1 - Serial communication signals (RxA_1 and TxA_1)
The FOX3-2G/3G/4G devices incorporate a full duplex serial channel in the accessory port which
allows two devices to communicate directly via RS232 serial ports. All supported baud rate are
controlled by PFAL commands. In order to communicate with the FOX3-2G/3G/4G devices, it is
recommended to use the FOX3-2G/3G/4G PromotionKit since you will find there all what you need
for your evaluation. The signals on these pins are obtained to RS232 compatible signal levels.
RxA_1
Receive channel and can be used for executing commands and
firmware update.
TxA_1
Output channel for responses and system data to any software
(e.g. HyperTerminal, Workbench).
