What is the Synchronized Readers option?

In Single, Burst, Continuous, and Self trigger modes, it is possible to synchronize image acquisition on multiple devices using the synchronization interface.

Synchronization allows using one shared strobed illumination to expose all sensors simultaneously. Optionally, you can trigger multiple synchronized readers in a defined sequence to avoid that opposing readers blind each other. Note that synchronized triggering only supports external illumination on the dedicated connector.

Note that this and other imager settings will not get synchronized by this mechanism - for example, you must configure exposure and gain on each reader individually. This feature only synchronizes the actual image acquisition, triggering happens through the existing Multi-Reader Sync mechanism.

To set up synchronized acquisition on the reader, enable PTP (Precision Time Protocol) on the Dataman Setup Tool's Multi-Reader Sync pane under Synchronized Readers (IEEE1588). Set Secondary Camera Only accordingly on each reader individually to define Multi-Reader Sync reader relations.

The following steps describe the setup in more detail:

  1. Check Enable PTP.

  2. Keep Secondary Camera Only checked if there is already a PTP primary reader clock in the network (uncheck the checkbox otherwise on at least one reader).

  3. Observe the protocol state in the Status box.

  4. Enable MRS Synchronized by PTP to synchronize Multi-Reader Sync triggering.

  5. Set Time between Trigger Start and the Synchronized Acquisition Timestamp if required. This represents the time the Primary Reader adds to the trigger to make sure all devices already received the TCP package before this timestamp.

  6. Set Local Offset Added to the Synchronized Acquisition Timestamp if required. This represents the time the secondary reader adds to the timestamp to realize offset image acquisitions.
