Outputs
Output features are configured by software. Any signal can be placed on any
output.
The main features of output signals are described below:
Note
•
Switching trigger delay to ON also switches external
Trigger_Mode_0 to ON.
•
This feature works with external Trigger_Mode_0 only.
Note
For a general description of the outputs and warnings see
the Hardware Installation Guide, Chapter STINGRAY out-
put description.
Signal
Description
IntEna (Integration Enable) signal
This signal displays the time in which exposure was made. By
using a register this output can be delayed by up to 1.05 sec-
onds.
Fval (Frame valid) signal
This feature signals readout from the sensor. This signal Fval
follows IntEna.
Busy signal
This signal appears when:
•
the exposure is being made or
•
the sensor is being read out or
•
data transmission is active.
The camera is busy.
PulseWidthMod (pulse-width modu-
lation) signal
Each output has pulse-width modulation (PWM) capabilities,
which can be used for motorized speed control or autofocus
control. See Chapter
Pulse-width modulation (Stingray housing
and Stingray board level models)
WaitingForTrigger signal
This signal is available and useful for the outputs in
Trigger
Edge Mode
. (In level mode it is available but useless, because
exposure time is unknown. (Signal always =0))
In edge mode it is useful to know if the camera can accept a
new trigger (without overtriggering).
