Align the reader time to be the same across all readers. (If you have an NTP server on the local LAN, please enable

it. See N, page 215).

On the Channels page, toggle the Advanced slider, and ensure all channels covering one direction of traffic have

the same (voting) Group ID (typically all group 0).

Configuring Legacy Cross Reader Algorithm (CRA) communication

Prerequisites: Accessing the Reader web interface, page 42.

1. Navigate to the Lane Assignment page.

Select Legacy CRA in the Inter-Reader panel.

Review the Cross-Reader reporting setting. This specifies if the reader sends the informational CrossR Vote

messages to the Lane Controller. A CrossR report means that an adjacent reader has reported the Vote message

to a LC. Recommended setting: Disabled

To ensure corect operation it is also necessary to:

Configure TDM Tag Programming (see Programming on page 51) ensuring that:

• TMP and TCP are enabled

• the Plaza IDs of all Readers at the plaza match

• the Reader ID for each Reader is different

On the Channels page, toggle the Advanced slider, and ensure all channels covering one direction of traffic have

the same (voting) Group ID (Group # 0). Multiple (voting) group IDs are not supported across multiple Readers.

Set the Reader clocks to within 2 seconds of the same time (either Manually setting the Reader time and date

procedure on page 216, or via the LC) or use NTP to time synchronize if there is an NTP server on the LAN.

Note: The Transponder Timeout, set on the Channels page, must be greater than the time difference

between all Reader clocks in the network.

Selecting the Voting Algorithm

By default the reader uses a Majority Voting algorithm which generates a single passage (a.k.a. Vote) report to

the lane controller, a fixed voting time (default 100 ms) from the initial read of a tag, and assigns the tag to the

RF channel with the highest handshake count. Another option "Report on First Read/Program" reduces average

reporting latency by immediately reporting a tag on the first read (or program, if the protocol supports

programming).

Prerequisites: Accessing the Reader web interface, page 42.

1. From the home page, select the Lane Assignment page.
