When you switch on an RFL100 data logger that is not connected to a VaiNet network, it turns on its radio and scans for VaiNet access points that are in installation mode and have available capacity. This means you must first install the necessary access point(s) and make sure they are in installation mode.
RFL100 will turn off its radio and try again later if there are no access points that meet the criteria. This can add a long joining delay as the retry interval becomes longer with repeated attempts, up to a maximum of 8 h 30 min.
-
After determining there is at least 1 access point that can be joined, the RFL100 connects to the access point with the best signal strength.
This initial connection also determines the VaiNet segment of the RFL100, as the segment of its first connecting access point becomes its home segment. A data logger will not leave its home segment unless it is released from the network.
Support for VaiNet network segments was added in AP10 access point firmware version 5.0.0. If your access points are using an earlier firmware version, your VaiNet network does not have segments.
RFL100 data loggers with firmware earlier than 1.8.0 can only join access points in the default A segment, and cannot join segments B–D.
- The connected RFL100 comes up in the connected viewLinc system as a new device. No measurement data is transferred and stored until the RFL100 is accepted into the system by a viewLinc administrator. If the RFL100 has been previously accepted and is now joining again, this step is skipped.
- If the RFL100 is rejected, it clears its VaiNet home segment information and starts the joining process from the beginning by scanning for access points to join.
