SW-2000T-CXP2 and SW-2000Q-CXP2
1 General
The JAI® Sweep+ Series SW-2000T-CXP2 and SW-2000Q-CXP2 are CMOS line scan cameras based
on a custom-made 2048 pixel imager with large square pixels of 20 µm for high responsivity.
They operate at a rate of up to 80,000 scans per second.
A beam splitter (prism) divides the incoming visible range light either into three or four
outputs: red, green and blue in the 3CMOS model and red, green, blue and infra-red in the
4CMOS model. Identical imagers are positioned with high accuracy to detect these bands. The
structures use common optical axis imaging, where the color components are all recorded at
the same time and seen from the same angle.
Both models output digital data in 8-, 10-, or 12-bit per channel formats, via one or two
CoaXPress (CXP) Links up to 6.25 Gbps each (approved up to 3.125 Gbps, two links). The camera
is configured via CXP interface using GenICamTM (a generic programming interface for machine
vision cameras) or via a 10/100 Mbps Ethernet port using an industry standard RJ-45 connector.
Special JAI lenses attach directly to the camera. An F-mount lens adaptor is the default. Others
can be added per request.

4 Input and output
4.1 CXP BNC connectors
Both connectors connect to one single point-to-point, coaxial, 75 Ω cable to output image data,
communicate with the camera and to input power. Please refer to official standard
(www.coaxpress.com) for more information on the cabling solutions. Each cable connects all
the related grounds together: electrical zero of the internal electronics to the chassis of the
camera and then via the shielding of the cable to the electrical zero of the other end, which is
then often connected to system ground via its chassis.
4.2 CoaXPress output modes
Bit depths of 8, 10, and 12 are supported. Cameras operate internally with more than 12 bits.
All blanks are electrically zeroes. The camera can be set to use only one connector or both.
4.3 CXP revision
The camera supports either revision 1.0 or 1.1. Default setting is for rev. 1.1. The revision can
be selected by writing to the CXP bootstrap register 0x4. The value 0x00010001 corresponds
with CXP1.1, while value 0x00010000 is written to use CXP1.0 after next boot-up.

5 Operation and functions
5.1 Introduction
5.1.1 Image sensor
The SW-2000T-CXP2 and SW-2000Q-CXP2 are built around a beam splitter prism and identical,
high performance CMOS line scan image sensors, which each convert the light collected by each
pixel into electrical charge. The amount of charge generated in each of the individual pixels is
basically directly proportional to the amount of light they receive.
The sensor has two options to store the charge at each pixel. These are called Quantum Wells.
The smaller well can hold about 60,000 electrons (60 ke-), while the larger has capacity for 360
ke-. The larger well should be used whenever feasible as it provides the best image quality due
to higher dynamic range and better signal-to-noise ratio (SNR), but also requires about six
times the light for the same response.
SNR is limited by the shot noise of the light itself and thus it is beneficial to collect as many
photons (light) as possible. The smaller well can be used to provide about six times as high
response to light, but with the cost of lower SNR and dynamic range.
Due to internal timings and processing there is one inactive period of 1 to 2 µs per each imaged
line when the received light is not used. Thus, the maximum time the light generated charge is
integrated, is always slightly shorter than the line period.
Correlated Double Sampling (CDS) is used for sampling the charge voltage and the reset level
to find the difference, which is then digitized into more than 12 bits and sent out of the sensor
for processing. An analog gain factor of 2 can be applied to the above mentioned difference
regardless of the well size. The selection is included in the SENSOR command syntax.
Please note that these cameras are not designed for low light conditions, but for high image
quality, which always requires a reasonable amount of light to be available.

5.1.2 Line image processing
The output data from the imager is buffered for further processing to be then finally sent out of
the camera via the CoaXPress interface. The processing chain is controlled by user accessible
commands. The DSNU corrector is calibrated individually for each camera at the factory and
always in use with fixed settings.
The scan rate and the integration of light within each line period can be controlled either by
the CXP trigger, internal timers, or a combination of these.
Serial communication channels are used to control and monitor the camera. Both the standard
CXP communication link as well as the Ethernet connection can be used for the same purpose
and even at the same time. Some functions are only supported via Ethernet.
5.2 Operating Modes
The camera can be configured to offer several operating modes that are fundamentally
different from each other. The operating mode is configured upon start-up and can only be
changed by issuing a new mode selection command and rebooting the camera.
5.3 DSNU Corrector
DSNU (Dark Signal Non-uniformity) describes the pixel-specific differences of response in dark,
while PRNU (Photo Response Non-uniformity) respectively describes the pixel-specific
differences of response to equal amounts of light falling onto all the pixels. Both are basic
sensor- and pixel-specific imperfections, which can be characterized and minimized. DSNU is
corrected already during production. Users may use the FFC function to further adapt the
camera into existing lighting conditions, if necessary.
5.4 Digital offset and gain stages
This block first shifts the digital pixel value up or down and then applies a digital gain. The
result is limited to stay between zero and the maximum digital value. Gain values lower than
the default 1x may cause the maximum output value to be lower than the maximum of the
range in use.
The offset block is a direct subtraction or addition. It does not define the target value for dark
response and has no feedback loop. That is why the gain block, which is simply a digital
multiplier, will also change the offset level, thus possibly causing a need to readjust the offset
value.

5.5 Test Pattern Generator
The cameras can send out five test patterns instead of the real imaged lines for purposes like
interfacing and problem analysis. The patterns replace the image data and can thus be used
also to test the following blocks. Each channel can be individually set to any of the patterns or
to show the real image data. Original, full patterns are available after switching off the FFC,
ROI and binning. Test data is also affected by the readout direction selection.
5.6 Flat Field Corrector, FFC
Factory calibrated DSNU corrector minimizes pixel-specific differences in darkness. There is no
need to correct the PRNU as a factory setting as it is less than the noise.
Real applications only rarely can provide equal amounts of light for all pixels. This is caused
mainly by effects like uneven distribution of light (light profile) or properties of lenses like
vignetting. Pixels at the center region tend to get more light, while the intensity decreases
towards both ends of the line image sensor.
The compensation method called Shading Correction results in a flat, equal response to light
under the same conditions in which the calibration routine was run. It is generally thought of as
a coarse correction to regionally scale or gain the pixel responses without paying attention to
any pixel-specific differences. Also, generally, a method called Flat Field Correction (FFC) is
used for operations where a similar correction is done more precisely and for each pixel
individually. The correction typically uses a 2-point linear method, where both the dark and
bright level pixel responses are equalized making it possible to have uniform response on all
light levels within the operating range of the camera. This would in fact be a complete, single
routine to perform DSNU, PRNU and Shading Corrections all at the same time, but the
corrections are separated in this implementation. DSNU correction is preset at the factory.
Shading correction is replaced by FFC, which operates assuming a fixed dark reference level
and includes the PRNU correction.
The FFC unit scales the pixel values by factors that are calculated by imaging a calibration
target in order to produce a uniform, flat response under the same conditions as where the
calibration routine was run. This can either be done individually for each channel or with one
common target level, which will result in white balance.
The dark reference is fixed already at the factory. Bright references are taken by averaging the
lines that were imaged from the calibration target.
15
SW-2000T-CXP2 and SW-2000Q-CXP2
5.7 Optical Corrector (OC)
This is a digital compensator to spatially shift imaged pixel values to match with the reference
channel pixel positions with the goal to remove effects caused by chromatic aberration.
The camera contains a list of pre-evaluated lenses and their imaging parameters like the range
of distances and field of view over which that correction is valid. Users can select any
correction on the list or create and add their own. The difference is that the factory made
correction use a high degree polynomial for best match also with non-linear increase of
chromatic aberration when going from the center of each line towards the beginning or end of
each line, while the user created corrections will only be linear. Please contact JAI for
instructions if you need to make your own correction.
5.8 Color Selector
The color selector is a switch matrix to connect any of the input channels to any or multiple of
the output channels. It is 3 by 3 on the 3CMOS and 4 by 4 on the 4CMOS model. Additionally, the
4CMOS model includes the possibility to select any of the three channels and send them out as
any of the formally 3-channel RGB formats.
5.9 Regions of interest, ROI
This block can be used to select up to four sections of pixels to be used as one combined line of
pixels. The purpose is to reduce the amount of data and to remove unnecessary regions.
5.10 Binning
Neighboring pixels can be digitally added or averaged as pairs. The resulting larger pixels are
then sent out as one. The resolution as well as the number of pixels will be half. The goal is to
have larger pixel area either to increase the response or to reduce noise.
5.11 Reversed readout direction
This function enables reading of the pixel values in correct order in cases where it is not
practical to install the camera to follow the intended imaging direction.
16
SW-2000T-CXP2 and SW-2000Q-CXP2
5.12
CoaXPress interface
CoaXPress (CXP) is a communication standard for imaging applications. It provides high speed
image data, communications and control, triggering and power input all over a single coaxial
cable as one CXP link. The transmission is point to point and possible up to distances exceeding
100 meters at low link speeds. Multiple links can be used in parallel. The first link acts as the
master and must always be connected. The so called Uplink for communications and control
runs always at the constant rate of 20 Mbps.
5.12.1
Selection of the revision (CXP 1.0 or 1.1)
The camera operates according to revision 1.1 as default, but supports also rev. 1.0. The
revision is selected by writing to the bootstrap register defined in the standard itself. The new
selection is automatically saved and taken into use at next boot up. The host should check the
setting during initialization and change it if necessary.
5.12.2
Link modes
The camera always boots up with one link at speed of 3.125G to negotiate with the host on the
transmission properties if used in CXP1.1 mode, which is the recommended and default option.
The same link speed is used also in the older CXP1.0 mode, but the initial boot up will use both
links if the camera was set for two cable operation (next table).
The host is typically a frame grabber board and acts as the master here. It can try any of the
standard link modes or read the preferred link mode that the camera has been set to show. The
host can then change the link speed, but it cannot change the number of links. The camera can
change the number of its links only by the ‘cxp config’ command.
The preferred link mode of the camera can be preset to be one of the ten options listed in the
table below. The command ‘cxp config’ is available only via the Ethernet connection as a
telnet command - not via GeniCamTM. The given values are immediately saved, but will not
become effective until the next restart. If the new mode is slower, please make sure that the
line rate value saved by the ‘CS SAVE’ command is not too high.

ECT test modes
The camera includes a special operating mode for the Electrical Compliance Tests (ECT) of the
standard. The camera will then output test mode data with the selected link speed. The new
values are automatically saved and taken into use at next boot up.
5.13 Ethernet interface
The 10/100 Mbps Ethernet port interface is provided as an alternative way to communicate
with the camera. Connection to Ethernet offers usual networking possibilities like remote
access and connecting multiple cameras together for control and monitoring. The standard
GenICamTM programming interface via the CoaXPress connection is allowed to be in use at the
same time. This of course requires caution if both channels are used for changing camera
settings.
Firmware updates are loaded only via this interface. Standard web browsers can be used to
establish connections to the internal web server, which includes a few basic functions like
downloading of some documents and supporting updates.
This port cannot be used for any actual image acquisition. Single lines (average of 32) can be
slowly read out and displayed as graphs by using the JAI Ethernet Tool software.

Firmware updates
It is possible to update or change the camera firmware without opening the housing. New code
is loaded in via the Ethernet port and with help of web browser user interface. There are two
kinds of firmware updates: MCU and FPGA. The MCU (microcontroller unit) updates affect the
user interface and high level features of the camera, while the FPGA (field-programmable gate
array) updates provide enhancements for low level or hardware related functions.
The MCU update is first initiated by the command FIRMWARE UPDATE and then completed with
help of the user interface that opens up by accessing the main page of the camera web server.
The FPGA update is done by directly accessing the respective update page.
Caution:
Ensure that the camera receives proper power during the complete firmware update
process.
A power break can potentially leave the camera in a state, where it cannot start again.
5.14.1 MCU firmware update
1. Make sure you have the correct file (.hex) for the camera model and the existing
configuration available.
2. Make sure you have a working communication via the Ethernet port.
3. Make sure you have a compatible web browser and can access the main page at
http://10.10.10.10.
4. Check and make a note of the existing configuration (telnet command: VER).
5. Save any settings that you want to keep. The camera will reboot during the process.
6. Initiate the camera by telnet command FIRMWARE UPDATE. You may still cancel the
operation after this. Send command CONFIRM when asked if you want to go ahead.
7. The green LED near the Ethernet connector should now start flashing rapidly. This
indicates that the camera is waiting for the new code.
8. Access http://10.10.10.10 or refresh the page if you already were there. The user
interface will let you browse for the new file (.hex) and upload it to the camera.

User interface for the MCU update.
9. You can still cancel the update here, in which case the camera will reboot once
automatically. The LED turns first into steady orange color. Wait until it becomes green
and steady again. You will have to make a new connection to the camera after this.
10. If you instead clicked on the upload button, this LED will continue flashing with multiple
colors during the loading. Do not interrupt the upload.
11. The camera will then automatically reboot. The LED will first go off, then turn orange
and finally green.
12. Close old communication sessions to the camera and establish new ones as needed.
13. Verify by command VER that the MCU version number has changed as intended.
5.14.2 FPGA firmware update
1. Make sure you have the correct file (.rbf) for the camera model and the existing
configuration available.
2. Make sure you have a working communication via the Ethernet port.
3. Make sure you have a compatible web browser and can access the main page
(http://10.10.10.10) already before initiating this update.
4. Check and make a note of the existing configuration. Telnet command: VER.
5. Save any settings that you want to keep. The camera must be rebooted during the
process.
6. Access http://10.10.10.10/FPGAupdate.html.
7. Browse and open the file (.rbf). You may cancel the operation now by closing the web
page. Click on Upload to proceed. Do not interrupt the upload.
8. The green LED near the Ethernet connector should now turn off.
9. Wait for the user interface page to change. This may take up to 3 minutes. The yellow
Ethernet LED flashes when code is being loaded. This should start within the first
minute.
10. Click on the ‘HOME’ button. The LED remains off.
11. The camera must next be rebooted. You may power cycle the camera or send the
REBOOT command followed by CONFIRM.
12. Close old communication sessions to the camera and establish new ones as needed.
13. Verify by command VER that the Logic version has changed as intended.

6 Command line interface
The command line interface provides an easy, interactive way to control the camera. All
commands can be given through the Ethernet interface using the Telnet protocol.
6.1 Connecting via Telnet
To connect the camera using Telnet:
• Consult your IT department to check if you can plug the camera to your local area
network with the default IP address 10.10.10.10. You may change the address by using
the NET IP command. Alternatively, you may configure your network card to build a
direct connection to the camera.
• Connect the camera to a local area network using a twisted-pair cable. A shielded cable
of category 5 or higher is recommended.
• Open a Telnet client on the computer. Two options are available from JAI. Please refer
to chapter 9 of this document. Also free or commercial Telnet clients can be
downloaded from various internet sites. The following Telnet clients are examples of
clients tested with the Sweep+ cameras:
o Foxterm
o PuTTY
• Open a Telnet connection to the IP address of the camera.
6.2 Entering the commands
The commands are typed in the client console window like in any command line interface. A
carriage return (ENTER) terminates the command line and transmits it to the command
interpreter in the camera for parsing and execution.
If the communication is coded into a software application then each line must have a carriage
return character (ASCII: 0x0D) at the end. Also, a line feed character (0x0A) may be sent after
the carriage return, but it is not needed.
Please note that the response time of some commands is considerably longer. Commands like
VER, STATUS, CS LOAD, CS LOAD2 and CS FACTORY RESET take almost 10 seconds to complete.
21
SW-2000T-CXP2 and SW-2000Q-CXP2
6.3 Command Format
The following notation is used for describing the command syntax:
•
•
•
•
•
•
•
BOLDFACE indicates the fixed command word that must be typed as it is
| A vertical line delimits alternative forms of a command
{braces} are used to group the alternative forms delimited by the vertical line |
<wedge brackets> are used to delimit the names of values
[square brackets] indicate an optional part that can be omitted
All parameters (numbers, options) must be separated by one or more spaces.
All commands are case insensitive; VER, Ver and ver are all equal
Example: LINE IT {<time>|<value>%}
A command described using this syntax has two alternative forms. The first form takes a time
as its only parameter, while the second form takes the percentage as an optional integration
time. The following commands are valid examples of this:
LINE IT 12
LINE IT 100%
(according to form: LINE IT <time>)
(according to form: LINE IT <value>%; the optional <time> is omitted)
When the command parameter is a physical quantity, the unit itself must not be given. For
example, the integration time is set to 12 µs but the microsecond unit is implied by the camera.
It must not be typed by the user.
Some commands can be applied only to one channel at a time by giving the channel identifier
as a parameter. All channels can be modified by one command by leaving the channel identifier
out. The optional parameter [ch] is the specifier of the channel. It is R, G or B for 3CMOS
models and R, G, B or I for 4CMOS models.
Examples:
GAIN R 1.5
GAIN B 3.1
GAIN 2.8
set red channel gain to value 1.5
set blue channel gain to value 3.1
set gain of all the channels to value 2.8

7 Description of commands
The commands can be divided into four groups:
Group A: General settings
MODE for selecting operating mode after boot-up.
NET for network settings for the Ethernet communication. The NET settings are saved
automatically.
CL SERIAL set the baud rate for Camera Link communications.
CS SAVE, CS LOAD, CS SAVE2, CS LOAD2 and CS FACTORY RESET for saving, loading or
restoring the settings of group B and C.
Group B: Commands affecting exposure
SENSOR for selecting the quantum well size and analog gain.
LINE RATE and LINE PERIOD for setting the scan rate.
LINE IT for selecting the actual light integration time.
LINE CTRL for selecting the trigger source.
GAIN for setting the camera gain.
OFFSET for setting the line offset value.
FFC for Flat Field Correction.
OC for the optical corrector.
Group C: Commands affecting image output format
CXP FORMAT for setting the pixel depth.
COLOR SEL for selecting the channels for the output.
READOUT for selecting normal or reverse readout direction.
ROI for selecting Regions Of Interest.
BINNING for combining adjacent pixels.
ACQ for start and stop of acquisition.
Group D: Utilities
HELP or ‘?’ for list of all commands.
VER for displaying firmware versions and camera identifiers.
STATUS to display camera information and settings.
TEST for selecting test patterns.
REBOOT for restarting the camera.
FIRMWARE UPDATE to change the MCU code.
23
SW-2000T-CXP2 and SW-2000Q-CXP2
The four groups will be described in detail in the following sections. Most commands display
help on how to use it if a space and a question mark is added after the command, and current
status of the function if the command is entered as such with no parameters.
The general principle with all the group B and C commands is that users may experiment with
the settings without losing the latest, saved and working setup (exception: CS FACTORY RESET).
New settings are in use, but not permanently saved, until the user decides to save them. It is
always possible to return to the latest saved settings either by sending the CS LOAD, CS LOAD2
or REBOOT command or power cycling the camera.
NOTE:
The CS FACTORY RESET command also saves the new values to the first memory
location like the command CS SAVE.

Group B: Commands affecting exposure
SENSOR – selects the quantum well size and analog gain
The sensor has two possibilities to collect the light generated charge. The default setting uses
the smaller well size for higher responsivity. The larger well size is used for a wider dynamic
range and a better signal to noise ratio, which results in more valid bits. The difference of the
responsivity between the two well sizes is approximately a factor of 6. Additionally, an analog
gain factor of 2 can be selected with both modes.
Command

SW-2000T-CXP2 and SW-2000Q-CXP2
7.2.2
LINE PERIOD and LINE RATE
These commands are used to set the scan rate for the internal timing generator, which is
selected by the LINE CTRL INT command. A new setting will be effective even though the
camera is in external timing mode. The LINE RATE is the inverse of the LINE PERIOD and if one
of them is changed then the other will be changed as well.
The LINE PERIOD command specifies the line interval in microseconds. The valid range is from
12.5 to 100000.0. The line period can be changed with the resolution of 0.1 µs. However,
internal rounding can take place. In this case, the resulting rounded line period length is
returned as the response to the command. The response has a resolution of 0.01 µs.
The LINE RATE command is used for specifying the scan rate as lines per second. The valid
range is from 10 to 80,000. The line rate can be specified in steps of 0.1 Hz. However, internal
rounding can take place. In this case, the resulting rounded line rate is returned as the
response to the command.
Command
LINE PERIOD ?
LINE PERIOD
LINE PERIOD <line period>
LINE RATE ?
LINE RATE
LINE RATE <line_rate>
Description
Returns the command syntax and the available range.
Returns the present line period .
Sets the line period as microseconds (µs) in steps of 0.1.
Default: 100.0.
Returns the command syntax and the available range.
Returns the present line rate. A value 8888.0 Hz indicates that
the CXP Link speed was changed and is too slow to support the
line rate in use or the rate loaded from memory.
Sets the line rate as lines per second in steps of 0.1 Hz.
Default: 10000.0.
Please note:
The settings made by commands MODE, CXP CONFIG, CXP FORMAT, BINNING and ROI may affect
the available range of values.
If the status inquiry ‘LINE RATE’ returns the value 8888.0 Hz, the camera has automatically
dropped the line rate to a safe value due to a too slow CXP Link speed that has been set after
the faster line rate was already once accepted. This can happen also when loading the factory
settings or the user settings from the first (CS LOAD) or the second location (CS LOAD2).

SW-2000T-CXP2 and SW-2000Q-CXP2
7.2.3
LINE CTRL - Exposure Control
The camera has three exposure control modes: internal, mixed, and Pulse Width Control (PWC),
which uses only one input signal to control both the line rate as well as the effective time to
integrate light.
The time when the exposure of one line ends and the exposure of the next line starts (change
of line) initiates a procedure that is common to all the modes. That includes stopping the
integration of light – or actually the collecting of the light generated electrons to the selected
Quantum Wells (one per pixel), sampling the respective charge voltages, and starting the
conversions into digital values to represent the amount of light that each pixel collected.
At the same time, the new line period starts and the camera starts to process the data that in
fact originates from the line period that occurred two periods earlier. There is a constant delay
from the end of each scan to the time where the first pixel value comes out of the camera. The
user always gets exactly one line of data for each request of a new line, but due to the internal
delay, it cannot always be the next line after the request. No lines though are lost in the
process.
It is possible to limit the amount of time that light is effectively collected (integration time)
within each scan period by using an electronic shutter function. The integration times of all the
channels are aligned with each other to optimise imaging of all the lines the same time.
Two general principles apply to all the modes. If the line period is too short, the request to
change the line is ignored. The camera will then wait for the next valid request. The second
principle is that if the integration time on any channel is too long in respect to the line period,
it will be cut short at the end of the line period. Information on the existing conditions is
available by the command LINE.
The source for these events can either come from the CXP trigger, or from internal timers, or
as a combination of these two.
The CXP trigger is generated by the host internally or based on its input signals. It is forwarded
to the camera as a transmission packet. In order to provide the camera a real time trigger, the
trigger packet transmission over the coaxial cable has the highest priority. The time delay
value between the trigger event and the trigger packet being sent is coded into the packet
itself. The camera uses these values to recreate the trigger event with low jitter and a fixed
latency.

7.2.3.1 Internal exposure control (command: LINE CTRL INT)
The scan rate is defined either by the LINE RATE or the LINE PERIOD command, which are
inverse of each other. The LINE IT command (LINE Integration Time) sets the length of the
exposure time per channel during each scan. Each Line IT must be shorter than the Line Period.
If the Line Integration time is commanded to be longer than the Line Period then the
integration time on those channels will stop at the same time as the line period ends.
The actual integration starts at the beginning of the line period. If the integration times have
differences between the channels, this would respectively cause misalignment between the
channels in the final images in the horizontal direction, which is perpendicular to each imaged
line, unless this is compensated. All SW-2000T and SW-2000Q models automatically center the
integration times. The longest time period is started at the beginning of each line period. The
midpoints of all channels occur the same time with the midpoint of the longest duration.
The Internal exposure mode cannot be synchronized to an external event. If external
synchronization is needed then the MIX or the PWC mode should be used.
7.2.3.2 Mixed mode exposure control (command: LINE CTRL MIX)
The line period is now the time between two consecutive rising edges of the CXP trigger signal.
The integration times are controlled internally by the command LINE IT per each channel. The
command ‘LINE IT [ch] <value>%’ is not available in this mode.
This mode is useful in situations where the integration times need to stay constant regardless
of variations in the line frequency. Each scan would then be triggered from some external
source, while the actual integration times of light would be programmed in advance as absolute
values. The maximum integration times are always about 2 µs shorter than the line interval,
which is common to all the channels. If any integration time is too long, it will be limited to the
maximum, in which case it will vary according to the line trigger input (CXP trigger) frequency.
The camera monitors this frequency. Individual, exact values can be read out by the command
LINE.
All the integration times are internally automatically centered the same way as in the INT
mode to minimize color mismatch.

Line timings in mixed control mode. The LINE IT shown here can be any of the RGB or
RGBI channels. Integration times are centered to occur at the same position.
7.2.3.3 PWC mode exposure control (command: LINE CTRL PWC)
Both the line period and integration time are controlled externally by the CXP trigger. The
integration time is same for all the channels. The time between two falling edges defines the
line period. Integration starts at the rising edge and stops at the end of the line period. Thus,
effectively the exposure time is equal to the HIGH period, while the length of the period equals
the line rate.
Fig.8.
7.2.4
Line timings in PWC control mode.
LINE IT - integration time
This command is used to control the integration time (effective exposure time) for each line.
The timing can be specified either as an absolute time in microseconds, or as percentage of the
line period. The integration time given as percentage of the line interval is recalculated
automatically when the line rate changes. The integration time set in absolute units remains
constant, unless the line rate setting forces the camera to shorten it.
Command
LINE IT ?
LINE IT
LINE IT [ch]
<time>
Description
Returns the command syntax and the available range.
Returns the present Line Integration settings.
Sets the integration time to <time> in microseconds for the selected

99998.50 with 0, 1 or 2 decimal places.
LINE IT [ch]
Sets the integration time to <value> per cent of the maximum
<value>%
integration time for the selected channel, where <value> is a numerical
value between 0.10 % and 100.00 % (default) with 0, 1 or 2 decimal
places. Not available in the LINE CTRL MIX mode.
The ‘[ch]’ is the specifier of the channel. R, G or B for 3CMOS models. R, G, B or I for 4CMOS.
If no channel is given, the same setting is applied to all the channels.

SW-2000T-CXP2 and SW-2000Q-CXP2
7.2.5
GAIN – digital signal gain
The gain control can be used to scale the camera response up or down individually per each
channel. In addition to the digital gain control the sensor responsivity can be selected to be
either Dynamic or Responsive giving a factor of 6 in responsivity due to the difference in
quantum well size. An analog gain of 2 can be added to both options. Please refer to the
SENSOR command.
It is recommended to use the SENSOR command first as far as possible and only then use the
digital gain to fine tune the response. Use of values lower than 1 may cause the maximum
output value to stay lower than the maximum value of the selected output range.
All changes in GAIN apply directly both to the signal and the dark level as well. If the dark level
needs to be maintained, it is necessary to modify the OFFSET value respectively. A coarse
estimate for the new OFFSET value can be calculated as follows and regardless of the bit depth
in use:
OFFSET ≈ 50 / GAIN – 50

Offset is always given as a 12-bit number. Offset changes in any 10
bit scale need to be multiplied by a factor of 4 to get the correct
value for this command. Respectively, 8 bit offsets must be
multiplied by 16. Default value is zero for all the channels.
The ‘[ch]’ is the specifier of the channel. R, G or B for 3CMOS models. R, G, B or I for 4CMOS.
If no channel is given, the same setting is applied to all the channels.
The <offset> is a positive or negative integer within the range of -1023 to 1023. This equals
±25 % of the full scale. The offset is always entered as a 12-bit number, which means that if you
have set the camera for one of the 8-bit output modes, you should multiply the intended offset
shift by 16 to get the offset for this command.
Please keep in mind that this command changes the digital output signal level just before the
gain factor is applied. A positive number raises the output levels, while negative numbers drop
the levels. The lower limit of the adjusted level is zero. Lower output values can be used for a
Contrast Expansion, where the darkest response of an application is brought closer to zero.

FFC – flat field correction
The function of the Flat Field Correction (FFC) is to compensate for differences in the optical
input. This can be shading due to lower transmission at the lens sides or similar optical
corrections. The Flat Field Correction should be done when the input light distribution is as
uniform as possible in order to avoid the possibility of the FFC correction adding errors to the
compensation when activated.
The procedure is then to establish a scene illumination as uniform as possible and to use the
intended optics and adjustments for the application. A uniform test target is needed. It is
recommended to calibrate the correction slightly off focal. This can be achieved either by
changing the viewing distance (recommended option) or by turning the lens a little off the best
focus.
The calibration routine first switches the correction off. The correction itself is a 2-point linear
calculation to compensate for all the pixel-specific differences both at the lowest response
levels (darkness) as well as at the bright levels, which exist when the routine is run. Two
reference lines are used. Both are an average of 32 lines. The dark reference was calibrated
already at the factory (DSNU). The bright reference is taken during the calibration.
Two modes exist. The image can be flattened either individually for each channel (PEAK MODE)
or to a common level (WHITE MODE), which results into a white balance. The target value for
all the pixels is then the brightest value per each channel or the brightest value on any
channel.
The correction unit is loaded with the new factors and the correction is turned on. The
correction factors are saved and loaded along with the commands CS SAVE, CS SAVE2, CS LOAD
and CS LOAD2, but because there is only one common memory location available, they actually
all operate with the same data.

7.2.8
OC – Optical Corrector
The line imagers have been aligned with each other at a micrometer range accuracy on the
same optical position. This is valid near the center pixels and the optical axis. Due to optical
properties of the beam splitter glass block and the lens, some chromatic aberration will be
present in the images towards both ends of the lines. This is caused by the different image sizes
on the sensors when looking at same imaging target.
The Optical Corrector effectively scales the images to be the same size. This means that a
detail on the target will be seen by the same pixel (index) on all the channels. The sensors have
some extra pixels to make sure that this scaling works for all the active pixels.
The aberration has been characterised at the factory in some selected cases. The respective
correction minimises the effect by bringing the counterpart pixel values together.

channels. Additionally, the 4CMOS models can send the data in 3-channel formats. All channel
specific commands still affect the original channels.
Command
Description
COLOR SEL ?
Returns the command syntax.
COLOR SEL
Returns the present setting.
COLOR SEL <c1> <c2> Selects the sources for the output channels. Default setting is ‘R G B’
<c3>
for the 3CMOS and ‘R G B I’ for the 4CMOS models. All the three or
four parameters must always be given. Please note that if the 4CMOS
model is set into a 3-channel output format, still four parameters are
required (the 4th will not be used).
Example:
COLOR SEL B G R
COLOR SEL R G I B
only: reverses the RGB order to be BGR.
only: swaps the B and I channels for output.
If the camera is set into any of the 3-channel output formats, the
contents of the RGB formats originates from R, G and I channel
imagers, respectively and the B channel is ignored.

7.3.4
ROI – regions of interest
This command can be used to select only specific sections of each line to be sent out. Up to
four regions can be defined. The selected parts of the line will be combined together to make
one shorter line. This increases the limit of the maximum line rate, the absolute maximum still
being set by the selected MODE. There are no empty pixels or spaces in between the regions in
the output data.
Furthermore, both binning and reversed readout order can be applied after this. Please note
that all pixel number indices still and always refer to the real, physical pixel numbers of the
sensor itself. First pixel is labelled as ‘1’ and thus the last pixel is number 2048.
For simplicity and first trials it is recommended to divide the full range of pixels into 8 sections
of 256 pixels each and then select individual or groups of sections by using the respective start
and end pixel indices.
Alternatively, the selections can be optimised by following these detailed rules. The start pixel
index must always be odd and smaller than the respective end pixel index at each region and
the regions must not overlap. All indices must be within range of 1 to 2048. Minimum width of
each ROI is 128 pixels, or 256 pixels if binning is in use. Each region may have individual
widths, but they all must be divisible by 64. Additionally, GenICamTM use requires that the
index of each end pixel must be divisible by 16. Changes to selections are made by defining
the complete set again.

7.3.5
BINNING – paring of pixels
Binning mode combines adjacent pixels as pairs either to double the response by summing the
two original values or to decrease noise by taking the average of the two values. ROI operation
may be in use prior to this. Binning decreases the number of output values by a factor of two.
This increases the limit of the maximum line rate, the absolute maximum still being set by the
selected MODE.
The two output values are added together in the summing mode and the output is limited to
the maximum digital value of the original pixel values. The averaging mode sums the two
values with no maximum limit and then takes the most significant bits into use to represent the
new combined pixel (lowest bit is removed).
The index of the first pixel of each pair must be odd.

Description

TEST - test patterns
The image data can be replaced by artificially generated, known test patterns to help
interfacing the camera, trouble shooting, and locating faults. Five patterns are available. They
all depend on the selected bit depth. The channels operate independently. Modes can be
selected or switched off individually by using the [ch] parameter. If no channel is given, the
command applies to all the channels.
Horizontal patterns ramp either up or up-down within each line with steps that equal the
selected camera output bit depth. All lines are then equal. Vertical patterns perform the same,
but in line to line direction. All values within each line are then equal.
The last pattern, P5, is a combination of these two directions to enable tracking in both
domains with a single test pattern. It starts exactly like the horizontal pattern P1, but when
advancing to next lines it leaves the darkest pixel values out one by each line. This effectively
also shortens the length of the horizontal sequences causing the position of the horizontal
ramps to move from line to line. The last line of one sequence then finally only contains the
maximum values making it look like one completely white line.
43
SW-2000T-CXP2 and SW-2000Q-CXP2
The lowest value is actually always the same as what the vertically changing pattern P3 would
have been if it had been started at the same time as P5. Thinking of the visual look of the
pattern P3, the correct look of this pattern (P5) can be better understood: the base level or the
darkest part of the pattern varies just like the vertically ramping P3 would vary. And while the
base level gets brighter the horizontal pattern also gets tighter as the lengths of those
horizontal ramps decrease making the respective image look like a pattern of higher
frequencies.
Please note that the selection is not saved nor loaded along with the other settings. Power
cycling, rebooting and loading of factory settings will switch the test mode off.
Command
TEST [ch] OFF
TEST [ch] P1
Description
No test pattern. Image data originates from the sensor(s). Default.
Sawtooth: horizontal rising ramps from 0 to maximum. All lines are
equal. In case of 8-bit output, the line graph includes 8 such periods
when advancing across the 2K pixels. The respective image should thus
look like this:
TEST [ch] P2
Triangles: horizontal ramps from 0 to maximum followed by falling
ramps from maximum to zero. All lines are equal. In case of 8-bit
output, the line graph includes 4 such periods when advancing across
the 2K pixels. The respective image should thus look like this:
TEST [ch] P3
Vertical sawtooth: rising ramps from 0 to maximum in line to line
direction. Each line has only one value for all the pixels. In case of 8-bit
output, the ramp from black to white takes 256 lines in the respective
image:
TEST [ch] P4
Vertical triangles: rising ramps from 0 to maximum followed by falling
ramps from maximum to zero in line to line direction. Each line has
only one value for all the pixels. In case of using an 8-bit output mode,
the cycle repeats itself every 512 lines. The respective image should
look like this:
44
SW-2000T-CXP2 and SW-2000Q-CXP2
TEST [ch] P5
A combination of rising ramps in both directions.
Horizontally the length of the sequence varies at the same phase as the
lowest value of the pattern changes from line to line.
Vertically the lowest value of each line-specific pattern varies from
line to line as rising ramps from zero to maximum, similarly to how the
pattern P3 behaves on its own.
The resulting image is shown below (8-bit). The first line is identical to
any line of P1. Then, instead of always starting from zero, the lowest
value will rise by one per line thus also making the sequence shorter.
This will continue making the pattern look like having higher
frequencies all the way until finally a completely white line is
produced. The sequence will then start over from the beginning.
TEST [ch]
Returns information on the current status of test modes.
Note:
The ‘[ch]’ is the specifier of the channel. R, G or B for 3CMOS models. R, G, B or I for 4CMOS.
All ramps increase or decrease by one level per pixel or line, where the step follows the
selected output bit depth of 8, 10 or 12 bits. When the direction of any ramp changes, the last
value of previous ramp is repeated once as the first value of the next ramp to keep the lengths
of the sequences equal, when feasible.
