Pins 1 and 2 are used to set the baud rate as shown in the following table.
Pin 1 Pin 2
OFF OFF 125 kbps (default)
ON OFF 250 kbps
OFF ON 500 kbps
ON ON Not allowed.
1. Always turn OFF the Slave's power supply (including the communications
power supply) before changing the baud rate setting.
2. Set the same baud rate on all of the nodes (Master and Slaves) in the Net-
work. Any Slaves with baud rates different from the Master's rate will not
be able to participate in communications, and may cause communications
errors to occur between nodes with correct baud rate settings.
