Hi,
For Module VMB1RS, the spec for RS232C baud rate is 57600, and I set PC com port baud rate also 57600 when I use velbusLink software, it is working well, but when I write my own firmware by using baud rate 57600, it is not ok, while I use 38400 , it is working well for sending command by 232 port, I don’t know why…
You can’t set the baud rate for the VelbusLink software, the VelbusLink software sets the baud rate for you, namely to 38400. The current baud rate for the VMB1RS is 38400.
