Rear Panel Switches
Two rotary switches are located on the rear panel of the RIO Drop Modules and are
used for setting RIO drop addresses (refer to the following illustration and table).
SW1 (top switch) sets the upper digit (tens); SW2 (bottom switch) sets the lower digit
(ones). The illustration below 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 module displays a
flashing ERROR A and ERROR B LED indicating an error condition. Only addresses
2 - 32 are valid.
