Description
Number of output pulses that a trigger output will generate.
A global triggering mode where all the triggers operate independent from
each other.
When an output stays in a given state (on or off).
The backlighting for the LCD allows the text to be visible. It is adjustable so
that for low-light conditions it won't ruin long exposures.
Abbreviation for milliseconds. A thousandth of a second (1/1000 seconds).
Power-Off. This lets you choose which trigger output will disable the sensor
power. The moment an event is detected the power will be turned off. This
is useful for eliminating red laser light from being in pictures. You can
choose from no outputs, all of them, or each individual output to cause the
disabling of the power.
Power Time Off. This is the duration that the sensor power will be disabled.
The global configuration is set to "Sequential Mode". This means that the
trigger configurations will follow in sequence. The opposite is independent
mode where they all function at the same time.
A global triggering mode where the triggers operate sequentially. That
means that the following trigger won't start until the current one completes.
To connect two wires together. Provide a path for current to flow with low
resistance.
This is the delay from when a camera is told to take a picture and when it
actually takes it. The camera performs several functions prior to taking the
picture (focusing, metering, etc) which can all add a delay. To make matters
worse it may even be a variable delay.
Synchronization mode. This is only available for the "delay" setting in
sequential mode. When this is set to "Yes", the delay will start when the
output of the previous trigger goes high. StopShot typically starts the next
trigger when the output goes low (Sync mode set to "no").
The time an input mode will wait for a specific event.
Trigger Mode. This is a global configuration that lets you choose the
behavior of StopShot. Examples are: Independent, Sequential, Time Lapse,
Flash measurement, etc...
The time off between output pulses.
When one of the three channels is configured as "Trigger", it will fire the
output after a configurable delay after seeing an input.
One of the three outputs of StopShot. The Red LED's correspond to the
three outputs.
Abbreviation for microseconds. A millionth of a second.
Displayed when an output is configured for "Manual" mode. Pressing the UP
or DOWN buttons will start the manual output, changing the displayed text
to "Active".
Short for "cross-beam". Two beams are set in an X formation that allows for
pin-point detection. StopShot's cross-beams may also be used in a staggered
method so that beams have to be crossed in a specific direction.
