LonWorks
When you handle the LonWorks Option Card:
• Do not contaminate the printed circuit board with fingerprints, moisture, or any foreign material.
• Do not touch components or leads.
• Handle the board by its edges.
• Isolate from high voltage or electrostatic discharge.
• Ensure that you are properly grounded.
Refer to
Appendix E (page 49) for the LonWorks Protocol Implementation Conformance Statement (PICS).
Configuring the RTU-MP for LonWorks Option Card
1
Turn off the RTU-MP's power.
NOTES
○
Changes made to the switches when the RTU-MP is on will not take effect until the RTU-MP has
been power 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.
