For a given channel, in the Dynamic Voting column, select Reader to allow the Reader to automatically adjust the

voting time according to prevailing traffic speeds. Typically all channels would be set to Reader, but that is not

required.

Review the Dynamic Voting Sample Size field. This is the number of previous transactions the Reader uses in the

specified channel to determine a new potential voting time. A new potential voting time is calculated after each OBU

passage.

Review the Dynamic Voting Threshold % field. This is the percentage by which the new voting time must change

from the current voting time, in order for the reader to switch to it. This is intended to prevent overly frequent

adjustments.

Configuring Channel Weight for straddle antennas

The handshake count of straddle channels (channels 2 and 4 in Figure 5-16) typically have less weight assigned

to them than non-straddle channels (channels 1, 3, and 5 in Figure 5-16).

Prerequisites: Accessing the Reader web interface, page 42.

1. From the dashbboard, select the Channels page.

2. Toggle the Advanced slider.

Enter a percentage in the Channel Weight field for each channel.

Result: The following screen appears.
