6. After installing, you can check if the yellow exclamation symbol disappear.

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：
