Example configurations for the synchronization of third party devices
zebris system is providing the sync-signal
Synchronize external 3
rd
party device by start/stop signal
Enable
“Active out”
. Connect the
“Active Out“ pin of the SYNC-OUT socket
to
start/stop input pin of the other device. The active out is set when the measurement
is started and removed when the measurement stops. If the external device needs
its start pin to be pulled low, set active out polarity to active low.
Note: Output pins may toggle during device initialization.
Synchronize external 3
rd
party device sample-by-sample via clock signal
generated by the zebris system
Enable
“Clock out”
. Connect the
“Clock Out“ Pin of the SYNC-OUT socket
to
the trigger input of the other device. The device will generate a trigger pulse each
time a single measurement is recorded.
Third party device is providing the sync-signal
Synchronize the zebris device by start/stop from an external 3
rd
party device
Enable
“Active in”
. Connect the activation signal from the other device to the
„
Active
In“ Pin from the SYNC-IN socket
of the zebris device.
If the external device sets its output to low level during measurement, set the active
in polarity to “active low”.
Synchronize the zebris device sample-by-sample by a clock generated by an
external 3
rd
party device
Enable
“Clock in”
. Connect the clock signal from the external device to the
„Clock
In“ Pin from the SYNC-IN socket
of the zebris device.
If the zebris device should trigger its measurement at the falling edge of the clock
signal, set the clock in polarity to “active low”. Otherwise, the raising edge will
trigger the measurement.
Combinations
All signals can be used simultaneously as well. If both active In and clock In are
enabled, the clock signal will trigger measurements only while the active In signal is
present. Trigger pulses from the clock In signal which occur while there is no active
In signal will be ignored.
