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).
Perform the following steps:
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. Enable
MRS Synchronized by PTP
to synchronize Multi-Reader Sync triggering.
4. Set the
Time between Trigger Start and the Synchronized Acquisition Timestamp
. This is the time the Primary
Reader adds to the trigger to make sure all devices already received the trigger message before this time stamp
(Primary Reader Only).
5. Set the
Local Offset Added to the Synchronized Acquisition Timestamp
. This is the time the Secondary
Reader adds to the timestamp to realize offset image acquisitions (Secondary Reader Only).
Note
: The DataMan 370 readers use IEEE1588 for high-speed trigger synchronization.
Note
: Multi-Reader Sync is only available in DataMan 370 readers with an -M option. For details, see
