Changing Baud Rates

Change the USART Baud Rate

Send the Following Bytes via RS-485:

9600 Baud USART: F3, 00, 25, 80

19,200 Baud USART: F3, 00, 4B, 00

38,400 Baud USART: F3, 00, 96, 00

57,600 Baud USART: F3, 00, E1, 00

115,200 Baud USART: F3, 01, C2, 00 (Experimental, Not recommended as there may be communications

problems)

Read USART Baud Rate: 245 (Three Bytes will be Returned Indicating the Baud Rate)

9,600: 00 25 80

19,200: 00 4B 00

38,400: 00 96 00

57,600: 00 E1 00

115,200: 01 C2 00
