Hybrid Recorder Mode
Data collection begins when a Start Record signal is received and continues until the unit
receives an Event signal. The unit then records for the post-Event time specified by the user.
The Event signal marks the T=0 point and all data recorded is available for download.
Continuous Recorder Mode
Data collection begins when a Start Record signal is received and continues until the Start
Record signal is released. The unit will then re-arm for another event. The LEDs on the unit
will flash blue slowly then rapidly, and then the status LED will become solid blue, indicating
the unit is fully armed. The unit will continue to record new events until it records the number
of events specified by the user. If an Event signal is received after the unit has re-armed,
the unit will disarm and no longer attempt to re-arm.
NOTE:
An event or trigger signal applied anywhere in the SLICE6 DAS
chain is distributed throughout the DAS chain and forwarded
to the SLICE6 Distributor, but is NOT exported outside the
SLICE6 Distributor. This also applies to level trigger.
Start Record and Event Initiation
The SLICE6 DAS supports multiple methods of initiating Start Record and Event signals.
Typically, Start Record and Event are initiated via an external hardware interface that
provides a discrete contact closure (CC) signal to initiate recording (Recorder mode) or mark
T=0 (Circular Buffer mode).
All SLICE6 DAS data collection modes support multi-event arming. A unit armed in a
multiple-event mode will re-arm when an event completes. The unit will stop re-arming when
the number of events specified by the user has been recorded.
SLICE6 DAS can be placed in an auto-arm mode that will cause the unit to arm automatically
when the power is cycled. This available with any available data collection mode.
Additionally, Circular Buffer mode supports level triggering. This method continuously
samples the incoming data and begins data collection if the data is above or below predefined
levels. For example, it might be useful to begin data collection when a certain accelerometer
experiences a force above 200 g. Using level trigger and Circular Buffer mode, SLICE6 DAS
can support this or any level-trigger signal on any channel.
CAUTION:
Level trigger is NOT recommended when SLICE6 DAS is used
for in-dummy testing.
