SensorTapReadout: (R/W) This feature sets/returns the mode to be used when reading pixel
data from the sensor. Currently supported mode selections include single tap and dual tap.
This mode applies to all sensors attached to the camera. If the sensors in the camera
heads do not support dual tap operation, the readout will be single tap and this command
will have no effect on operation. Not all camera heads will support dual tap readout. The
MEGAPLUS full-frame heads including the ES 1602*/3 and ES 3200 do not support dual tap
operation. The effect of this function in custom mixed-sensor configurations will be defined
per application. One= single tap/Two=dual tap
NOTE: Sensor tap readout configuration does not affect the camera's data output
configuration. When a sensor is read in dual tap mode, the two taps are interleaved in
the camera back into a single image stream. Not all camera heads will support dual
tap readout. The MEGAPLUS full-frame heads including the ES 1602
*
/3 and ES 3200
do not support dual tap operation.
StrobeDelay: (R/W) This feature sets/returns the delay between the time that the trigger signal
is received and the time that the strobe signal is output. Delay is in milliseconds. If a delay
of zero is specified, the strobe will be output immediately after receipt of the trigger. If a
delay period is specified that is longer than the integration time of the sensor (determined
either by programmed value or pulse width), the strobe will be output immediately at the end
of the integration period. Min: 0, Max: 999
StrobePolarity: (R/W) This feature sets/returns the output strobe signal polarity.
Negative/Positive
TriggerInputPolarity: (R/W) This feature sets/returns the trigger polarity setting for the
controller. A positive polarity means the trigger signal will be considered active when the
signal is in a high or true state. Negative polarity is the reverse - the trigger signal will be
considered active when the signal is in a low state. Negative/Positive
TriggerIntTime: (R/W) When operating in triggered modes that use a programmable integration
time, this command specifies the integration time that will be used for the triggered
exposure. This control offers a range of integration time values that can be beyond the
range available with the standard free-run sensor integration time. The specified integration
time will be applied to all Camera Heads when triggering is enabled and a trigger is
received. Note: In some trigger modes (for example, Mode 1) integration time is controlled
by other means, such as pulse width. In this case the Triggered Integration Time value has
no effect. Unit is milliseconds. Specified as floating point with 3 digits of fractional precision
(x.xxx) to provide 1 microsecond resolution. Range is 0.001 (1 µsec) to 10,000 msec (10
seconds) for trigger modes 0-6. For trigger mode 7, range is 0.010 (10 µsec) to 600,000 (10
minutes). Min: 0.01, Max: 600,000
Important Things to Know
The Triggered Integration Time value applies to all attached camera heads. This value
will be applied in trigger mode 0 (Edge Trigger, Asynchronous Reset), 6 (Periodic
Interval), or 7 (Overlapped Edge Mode) active.
This function controls triggered integration time only. When the camera is operating in
free-run (video) mode, integration time is controlled via the ExposureTimeAbs feature.
