Switch Assemblies Status Word
The six-position dip switch is used to configure the communication
channel and other miscellaneous information. The switches have the
following definition:
•
SW-1.1 and SW-1.2: Define the communication channel baud
rate as shown below.
•
SW-1.3: When ON means that the channel is configured as DH+.
When OFF means that the channel is configured as RIO.
•
SW-1.4: User identification SW. This switch can be used to
differentiate one 1747-BSN from its counterpart and identify
when a switchover occurs. This switch is user-configurable and
does not affect the operation of the module.
