This section describes the Slaves' node address setting, baud rate settings,
and hold/clear outputs for communications error setting. These settings are
made using the following pins on the DIP switch.

The node address of the Remote I/O Terminal is set with two rotary switches.
The 10s digit is set on the left and the 1s digit is set on the right. Any node
address within the setting range can be used as long as it isn't already set on
another node.
Note 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 duplica-
tion error).
Pins 1 and 2 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. Furthermore, a node with an incor-
rect baud rate may cause communications errors between nodes with cor-
rect baud rate settings.
