Lane Assignment voting for ORT applications
ORT lanes allow OBUs to cross multiple capture zones. The Readers must assign an OBU to one RF
channel to prevent duplicate transactions.
Selecting the correct communication method
The communication method determines how Readers communicate with each other to share
information for determining lane assignments. This is important for situations similar to that shown in
Figure 5-12, where, to assign the OBU to a lane, Reader 1 and Reader 2 need to share handshaking
information.

Configuring Lane Voting over an Inter-Reader (IR) network
This procedure allows you to configure the Reader correctly to ensure accurate lane assignment and to
prevent duplicate reports.
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 40. You must have Advanced
User permissions.
Note: Badger-Style CRA: there is no physical link between the Readers, such as an IR Network.
Instead, the first Reader to contact an OBU programs the OBU; all other Readers that subsequently
contact the OBU will see that it was recently programmed and ignore the OBU.
Ethernet: An IR Ethernet network connects the Readers together and handshaking information is
shared between Readers. The Readers assign the OBU to one channel and all other transaction
reports from other Readers are suppressed.
