SW1 (the top switch) sets the upper digit (tens) of the address; SW2 (the bottom
switch) sets the lower digit (ones) of the address. The illustration shows the correct
setting for an example address of 11.
The following table shows the node addresses of the SW1 and SW2 switches.
NOTE: If "0" or an address greater than 32 is selected, the RIO module displays a
flashing Error A and Error B LED to indicate an error condition. Only addresses 1-
32 are valid.
