Each Slave's node address is set with pins 1 through 6 of the Slave's DIP
switch. Any node address within the setting range can be used as long as it
isn't already set on another node.

1. Refer to Appendix A Node Address Settings Table for a complete table of
DIP switch settings.
2. The Slave won't be able to participate in communications if the same node
address is used for the Master or another Slave node (node address du-
plication error).
Pins 7 and 8 are used to set the baud rate as shown in the following table.
(These pins are factory-set to OFF.)

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 won't be
able to participate in communications, and may cause communications er-
rors to occur between nodes with correct baud rate settings.
