Lane Assignment
The reader can perform lane asignment (voting) to identify the most probable lane in which the OBU resides.
This is used when producing VOTE or POST messages to the Lane Controller. The settings for voting method
and voting communication are defined on the Lane Assignment page, shown below.
1. From the dashboard page, click the Lane Assignment button.
Result: The following screen appears.
The default lane assignment method is "Majority Voting", which means that the reader generates a VOTE report
to the lane controller based on which channel has the highest handshake count at voting time. The voting time
is settable on the "Channels" page. The other lane assignment option "Report on First Read/Program" is a
legacy mode from a previous generation of the reader. In this mode a report is generated as soon as a tag is
seen and programmed. This legacy mode is not recommended for ORT use.
Multiple Reader Lane Assignment
ORT lanes allow OBUs to cross multiple capture zones which may cross between readers. The Readers should
assign an OBU to one RF channel to prevent duplicate transactions.
