6.2 The “Timing” sheet
Trigger Mode
[Auto Sequence] The camera will optimize the image recording to achieve
the best possible frame rate.
n the [auto sequence] exposure control mode, the camera determines
the fastest possible image uptake rate depending on the adjusted
exposure time and the required readout time. After a start command is
given, the sequential recording is started until a stop command is given.
[Soft Trigger] Single images can be recorded with Camware control. The
single image can be acquired by pressing the "Single Trigger" button. This
button appears after pressing the “Start Record” button (see chapter 7.2).
Other signals cannot influence this operating mode.
[External Exp. Start] The image acquisition is triggered by an external
signal. t is also possible to force a software trigger for a test image with the
"Single Trigger" button.
n the [External Exp. Start] exposure control mode, single image
recording is started by the falling or rising edge of the voltage signal at
the BNC input (see chapter 6.7).
pixel clock intrinsic + system delay
55 MHz tbd
62 MHz tbd
[External Exp. Ctrl] An external signal, which is applied to the trigger input,
controls the start and the duration of the exposure (see chapter 6.7).
Timing
The exposure and delay time can be adjusted in steps of 1µs.
exposure time delay time

6.3 The “Sensor (Size)” sheet
Binning
Feature not available for pco.dimax
Sensor Format
The implemented sensor has the option to readout a standard size (effective
pixels recommended by the sensor manufacturer) or an extended size,
which adds optical black pixels, which can be helpful for calibration or
control purposes. n extended mode, you will not increase image size!
Region of Interest
The RO (region of interest) selects only a part of the sensor to be read out,
in order to speed up the frame rate and to save memory. Due to the sensor
structure and readout electronics the selectable region is always symmetric
about the center.
ncrements horizontal: 48 pixel steps
ncrements vertical: 4 pixel steps
Please see next page with table of possible regions of interests.

Double Image
This feature is widely used for particle image velocimetry (P V)
measurements, but not yet released for the pco.dimax.
IR Sensitivity
Feature not applicable for pco.dimax
Offset Control
Offset control is done automatically for optimal results. User control is
disabled.
B/W Noise Filter
n the pco.dimax an optimal hot pixel correction is already integrated.
Conversion Factor
The conversion factor defines how many charges (electrons), which have
been generated by light in the image sensor in each pixel, are necessary to
generate one count (one intensity level) in the digital image. Therefore, the
conversion factor describes the gain that is applied to the signal before it is
converted into a digital value. The conversion is optimized for the
pco.dimax @ 10 e-/count.
Electronics Temperature
Display of electronics and sensor temperature.
Active cooling by fan is implemented in the pco.dimax. There is no need for
Peltier cooling. Due to digital temperature compensation and sophisticated
electronic design the pco.dimax comes with ultra stable offset, where there
is no need for extra black or current references.
6.5 The “CamRam” sheet
The CamRam sheet is for controlling the camera built in memory (camRAM).
You have the possibility to record into 3 different segments.

6.6 The “Recording" sheet
Recorder Mode
n sequence mode the camera will stop after the memory (i.e. the active
camRAM segment) is completely filled. n ring buffer mode the camera will
record until it is stopped.
Acquire Mode
The acquire mode gives you the ability to enable or disable the recording by
an external signal. f set to external the camera will only record images if the
external signal enables recording (see chapter 6.7).
Time Stamp
A time stamp can be placed into the upper left corner of the image. t can
be either off, binary, binary with text or text only. n binary mode there will
be filled the first 16 pixels with the time stamp. n binary and/or ASC there
will be placed text into the image in a way, where the content of the image
will be replaced by the text. This feature is not yet released for the
pco.dimax!
Record Stop Mode
After ‘stop recording’ the camera will continue recording for the number of
images entered in ‘Skip mages’. n this mode you are able to capture a free
selectable amount of pre- and post-event images.
