In

Self
trigger modes, it is possible to
synchronize image acquisition
on multiple
devices using the synchronization interface. Synchronization allows using one shared strobe illumination to expose all
sensors simultaneously. You can synchronize multiple readers with optionally triggering them in a defined sequence to
avoid that opposing readers blind each other. 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 DataMan 370, enable PTP (Precision Time Protocol) on the
Multi-Reader Sync
pane of the DataMan Setup Tool under Synchronized Readers (IE1588). Set the Secondary Reader Only accordingly on
each reader individually to define
Multi-Reader Sync
reader relations.
The setting in 7 steps:
1. Check the Enable PTP check box.
2. Keep set the Secondary Reader Only check box if there is already a PTP master clock in the net (uncheck
otherwise on at least one reader)
3. Tune fine by Priority 1 and Priority 2
4. Enable Multi-Reader Sync by trigger: Use PTP to actually sync Multi-Reader Sync triggering
5. Time between Trigger Start and the Synchronized Acquisition Timestamp: Time the Primary Reader adds to the
trigger to make sure all devices already received the trigger message before this time stamp.
6. Local Offset Added to the Synchronized Acquisition Timestamp: Time the Secondary Reader adds to the
timestamp to realize offset image acquisitions.
External Triggers
If you are using external triggering, you can use any of the following methods to trigger your DataMan 370 reader:
