Issue Details

I am using RS-422 and my application needs an odd baud rate such as 520562 bps. Can I configure my module to communicate at this rate? 


You can change configure the baud rate by right clicking on the module then select properties then choose <other> in the desired baud rate, then type the baud rate needed. 
Note that the desired baud rate will be rounded with a bit of uncertainty to the desired value. For example for 520562 bps the error will be 1.17% as shown in the diagram below.
