Timestamp Value timestampValue Returns the 64-bit value of the timestamp, which is the
internal Clock timer or the PTP clock timer, depending on
the Timestamp Source selection.

TimeStamp Source timestampSource Specifies the source used as the incrementing signal for
the Timestamp register.

Internal Clock InternalClock The timestamp source is generated by the camera internal
clock. Refer to the timestampTickFrequency feature for the
time base.
IEEE1588 IEEE1588 The timestamp source is controlled by the network
IEEE1588 protocol. This source is automatically selected
when PTP mode is enabled.
Timestamp Tick Frequency timestampTickFrequency Indicates the number of timestamp ticks (or increments)
during 1 second (frequency in Hz). This feature changes
depending on the TimeStamp Source.

Timestamp Latch Source timestampLatchSource Specifies the internal event or signal that will latch the
timestamp counter into the timestamp buffer.

Frame Start FrameStart The timestamp is latched on frame start.
Timestamp Reset Cmd timestampControlReset Resets the timestamp counter to 0. This Feature resets
both the internal Clock timer and the PTP clock timer. Note
that the PTP Mode must be disabled first to reset the PTP
clock timer.

Start of Frame FrameStart Event sent on control channel on an Active Frame. This
occurs with the start of the exposure delay.
Start of Exposure ExposureStart Event sent on control channel on start of exposure.
End of Exposure ExposureEnd Event sent on control channel on end of exposure.
Acquisition Start Next
Valid
AcquisitionStartNextValid Event sent on control channel when the AcquisitionStart
command can be used again.
Valid Frame Trigger ValidFrameTrigger Event sent on control channel when a valid frame trigger is
generated.
Invalid Frame Trigger InvalidFrameTrigger Event sent on control channel when a frame trigger occurs
in an invalid Trigger region. Therefore the trigger is
rejected and no frame acquisition occurs.
Image Lost ImageLost Event sent on control channel when an image is lost due
to insufficient memory.
Counter 1 End Counter1End Event sent when counter 1 has reached the
counterDuration count.
Line 1 Rising Edge Line1RisingEdge Event sent when a rising edge is detected on input line 1.
Line 1 Falling Edge Line1FallingEdge Event sent when a falling edge is detected on input line 1.
Line 2 Rising Edge Line2RisingEdge Event sent when a rising edge is detected on input line 2.
Line 2 Falling Edge Line2FallingEdge Event sent when a falling edge is detected on input line 2.
Events Overflow eventsOverflow Event sent on control channel when all previous active
events have been disabled because the camera cannot
send them fast enough, generating in internal message
overflow. Required events must be re-enabled manually.
