Selecting the Voting Algorithm
Prerequisites: Connect the service laptop to the Reader configuration port to access the CTM web interface.
Refer to Connecting a service laptop to the Reader, page 47.
Majority: The OBU is assigned to the channel with the most handshakes.
Interpolated: The Reader determines which set of three adjacent channels has the highest
handshake count. The OBU is then assigned to the channel within this set with the most
handshakes.
1. Select the Configuration link on the left side panel.
2. Click the Lane Assignment tab.
Result: The following screen appears.
3. Select either Majority or Interpolated from the drop-down box of the required protocol located in the
Lane Assignment Algorithm box.
Note: If Interpolated is selected from the drop-down box, channels with handshake counts that differ less
than the Handshake Equalization Ratio will be considered to have an equal handshake count
since the difference is not considered significant.
4. If Interpolated was selected in step 1, enter a percentage in the Handshake Equalization Ratio field.
Configuring Voting Time
Manually setting a voting time gives a fixed voting time to each channel. Dynamic voting time allows
the Reader to calculate and base the voting time on the average capture zone span time (the time it
takes for an OBU to pass through a capture zone).
