4-4 Configuration
Logical Group Number (SW1-7,8)
SW1 switches 7 and 8 determine the starting logical group.
Valid starting logical group numbers are determined by the:
•
addressing mode (2-slot, 1-slot, or 1/2-slot)
•
specialty I/O mode (discrete or block transfer)
The default position is logical group zero as shipped from the factory.
If an invalid starting logical group number is selected, an error occurs.
DIP Switch SW2
Baud Rate (SW2-1,2)
SW2 switches 1 and 2 determine the baud rate the 1747-ASB module
operates at while communi cating across the RIO link.
The default is 57.6K as shipped from the factory.
