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.
Node address setting: Pins 1 through 6
Baud rate setting: Pins 7 and 8
Output hold/clear setting:Pin 10 (affects only outputs)

Baud rate setting
The node address of the Remote I/O Terminal is set with pins 1 through 6 of
the 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 dupli-
cation error).
Pins 7 and 8 are used to set the baud rate as shown in the following table.
Pin 7 Pin 8 Baud rate
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 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.
