Hello,
Is there a way to change the default RS485 baudrate (which is 38400 bps) ?
Any existing register to change the RS485 parameters ?
Thanks in advance !

how to change baud rate:
step1: modbus 06 command write address 2 (data:0-4 0:4800,1:9600,2:19200,3:38400,4:57600)
step2: modbus 05 command write address 501 = true will save the config.
step3: power off->on of board.
if forget the setting. hold on the "RESET" button > 3 seconds, it will auto set to default setting with 38400bps.

Many thanks for your reply.
I will try the procedure.
As a suggestion, I think it would be good to include the tip in the instructions manual.
Best regards,
Laurent
