Synchronization burst: start burst to synchronize the gates (Period of T Scan ms)
Processing time (Pt): depends on the number of tags to be detected and the settings. The
fastest is when only detection is used (EAS burst or AFI), the slowest when all features are
used (AFI + Read AFI + Read 16 blocks of memory). Refer to the figures in Table 3:
Scanning Duration.

Scanning Duration.
Synchronization process for 3 pedestals:
1- The master scans the configured chip, then sends the synchronization burst to Slave1
2- Slave1 scans the configured chip, then sends the synchronization burst to Slave2
3- Slave2 scans the configured chip, and then sends the synchronization burst back to either
the master when in hardwire mode or to the Slave1 in wireless mode.
This process is repeated indefinitely.
In case the master does not receive back the synchronization burst from the last slave after a
defined period, it will automatically restart the synchronization process.
defined period, it will automatically restart the synchronization process.
The number of pedestals is not limited to any particular number as long as each gate is close
enough to its neighboring pedestal and that the overall scanning time does not exceed a few
100ms to allow for a safe detection at 1m/s pace trough any gate.
