Strobe: An isolated open collector output signal with 1k pull-up. When asserted (low) 'Strobe'
indicates that the electronic shutter is open. Strobe is low for the duration of the exposure.
F-Sync: The only signal can be set as an output or input. By default, it is output (sync-
internal).
Output signal is a frame sync pulse from the camera's frame rate generator. A short (few
hundred ns depending on camera model) negative pulse with the falling edge is used as
timing reference. Input signal is active on falling edge. (Default state is high.)
TC-Out: A positive polarity time code signal. Normally an unmodulated (dc-shifted)
IRIG-B (at RS-232 levels) which follows the internal time base of the camera. It is
recommended not to process the 'TC-Out,' since a processed signal will not represent
an accurate time code.
Auto-Trigger: Used to output a hardware trigger signal or pulse with the duration.
Software Trigger: An active high-output signal (pulse) generated as a result of the
trigger protocol command.
Recording: An active high-output signal indicating active recording into a RAM partition.
Event In: If the input is sampled low at the end of an exposure, an 'E' (Event) bit in the
frame's timestamp is set.
Memory Gate In: If the input is sampled low at the end of an exposure, the corresponding
frame is skipped from storage to RAM.
Pre-trigger: An active low-input (default high) signal. Keeping this signal low for enough
time (10—500 ms or until 'Ready' signal goes high) will make the camera start recording,
if it has an available RAM partition.
Aux Trigger: An input signal active on the rising edge (default high). An alternative
trigger input that can be processed through the pulse processor and assigned to
different ports.
