2: Using the ProtoCom/ProtoCom-Lon
Figure 2.11: Connecting Power to the ProtoCom/ProtoCom-Lon
2.9: Step 9 - Turn Off Auto-discovery After Completion to Save
Configuration
The S3 DIP Switch for enabling Auto-discovery was set in step 3, Section 2.3. Once
power is applied to a ProtoCom/ProtoCom-Lon that is set to enable Auto-discovery,
the unit takes about 3 minutes to complete the discovery of all of the EIG meters
attached to the ProtoCom/ProtoCom-Lon and the loading of their data points.
Once the ProtoCom/ProtoCom-Lon has discovered all of the connected EIG meters,
set the S3 DIP switch to the OFF position to save the current configuration. The OFF
position is when the DIP switches are set closest to the outside of the box.
