Remote Adapters
Section 4-6
Note
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.
Setting Pins 9 and 10
The functions of pins 9 and 10 differ for inputs and outputs, as shown in the
following diagram.
Pin 9:
Reserved (Always OFF)
Pin 10: As follows:
Inputs:
No function (Always OFF)
Outputs:
Hold/Clear outputs for communications error
OFF (Clear):
All output data from the Master will be cleared to 0 when a
communications error occurs.
ON (Hold):
All output data from the Master will be retained when a
communications error occurs.
Pins 9 and 10 are factory-set to OFF.
