Reader-to-Reader synchronization requires the following programmable options on the web interface:

• Synchronization Search Time (maps to sync frame timeout in MPR2)

• Synchronization Delay (new feature not supported in MPR2 used for cable delays)

• Synchronization Frame Start Delay

• Sync Recovery Time (currently hardcoded default 20ms in MPR2)

• Sync Recovery Attempt Limit (new feature not supported in MPR2)

• Sync on Skipped Sync Frame

Note: Reader-to-Reader Sync Recovery occurs on a loss of synchronization with the external reader

network.

Synchronization search time

Synchronization search time indicates how long the reader waits for reader to reader sync before falling into

synchronization recovery.

If the reader detects synchronization prior to the expiry of this timer, it exits search mode and performs one of

the following actions.

• Falls into Synchronization Delay if programmed

• Falls into synchronization frame start delay if programmed

• Begins firing its multi-protocol acquisition sequence.
