To set up the RTU Open for the LonWorks Option Card (Part #LON-OC)

Turn off the RTU Open's power.
NOTES
Changes made to the switches when the controller is on will not take effect until the power has been
○
cycled!
The controller's rotary address switches are not used when the LON-OC is installed. That's because each
○
LON-OC has a 48-bit Neuron ID that makes it unique on the LonWorks network.
