Testing
INTERFACES
RS23 2
Connect RS232 and USB interface to PC. Open two Serial Assistance Software and
set them with same baudrate, test them as below：
RS48 5
Connect RS485 interface to RS485 interface of target board (here we use our
RS485 board to test), A to A and B to B. Open two Serial Software on PC and
test it. （ Note that RS48 5 Board should pull- high RSE to send data and pull0
download it to receive））
TTL
Connect TTL interface to other UART board and connect to PC, open two Serial
software and test：
