ATTENTION: To avoid interference and loss of data between

adjacent reader, readers must be synced.

Tests should be carried out under live traffic conditions to ensure that RF signal reflections that come off

moving vehicles do not cause inteference.

If Reader-to-Reader RF interference exceeds the in-band limits then the Readers must be synchronized

CTM-to-CTM synchronization in Redundant Reader.

The following requirements apply to synchronization between Primary and Secondary CTMs.

• Synchronization between Primary and Secondary CTMs (intra-reader sync) occurs whenever the

reader is configured for redundancy.

• Loss of CTM synchronization does not affect the synchronization of readers connected in a network

(Reader-to-Reader synchronization).

• A redundant reader currently operating on the Primary CTM does not fall into the Reader-to-Reader

Sync Recovery routine if synchronization is lost on the Secondary CTM and vice versa.

• If synchronization is lost between CTMs, a loss of redundant sync signal is reported.

Reader-to-Reader synchronization

To enable reader sync, navigate to the Tag Protocols page, click on the + icon, and add a

element. To remove sync, select the sync element, and click the icon.

The following is a sample with sync added to a TDM frame sequence.
