4.3 Camera Link output modes
All these modes are presented in the standard according to the names shown on the first line.
This table shows the use of these configurations to implement various data output modes.
Bit depths of 8, 10, and 12 are supported, where MSB is labeled as M11 and LSB as M0. Camera
operates internally with more than 12 bits. All blanks are electrically zeroes.
Dual and Triple modes send data from multiple pixels in parallel to enable higher scan rates
and/or longer cable lengths. Camera Link is nominally limited to 10 meters and 85 MHz. Data
from two or three consecutive pixels is sent out at once, where the index n-1 refers to the
previous pixel and n-2 respectively to the pixel before that. If the pixels are numbered from 1
to 2048, then the transmission in 8-bit Triple mode starts with a 24-bit package, where port A
shows the 8-bit value for pixel #3, Port B equals pixel #2 and Port C contains data from the first
pixel. Respectively, the Dual modes effectively send the data out as odd and even numbered
pixels, two in parallel.

5 Operation and functions
5.1 Introduction
5.1.1 Image sensor
The SW-2000M-CL-65 is built around a high performance CMOS line scan image sensor, which
converts 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 of 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).
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 higher
response to light, but with the cost of lower SNR and dynamic range.
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.

5.1.2 Image processing
The output data from the imager is buffered for further processing to be then finally sent out of
the camera via the Camera Link 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 Camera Link input signals CC1 and CC2, internal timers, or a combination of these.
Serial communication channels are used to control and monitor the camera. Both the standard
Camera Link serial channel 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.

SW-2000M-CL-65

5.2 Operating Modes
The cameras 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 Offset and gain stage
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.
5.5 Test Pattern Generator
The SW-2000M-CL-65 can send out five, defined 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. 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 minimize pixel specific differences in darkness. There is no
use 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
SW-2000M-CL-65
13
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 of SW-2000M-CL-65 offers the possibility to scale 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. A constant value (same as
DSNU target value) is used as the dark reference. Bright references are taken by averaging the
lines that were imaged from the calibration target.
5.7 Region 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.
5.8 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.
5.9 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.
SW-2000M-CL-65

5.10 Camera Link interface
One Camera Link connector is available to connect standard Base Configuration interface
devices (frame grabber boards, etc.) to receive image data, to control the scan rate and
exposure of the camera, as well as to communicate via the Camera Link serial channel.
Output modes include possibilities to transfer two or three pixel values at the same time to
increase throughput or to decrease the pixel clock frequency. The clock rate can be adjusted
between 20 to 85 MHz in steps of 5 MHz. Lower frequencies may allow use of longer cables.
5.11 Ethernet interface
The Ethernet interface is provided as an alternative way to communicate with the camera. The
10/100 Mbps port provides very fast data transfer rates compared to standard Camera Link
speeds, which are all less than 1 Mbps.
Connection to Ethernet offers usual networking possibilities like remote access and connecting
multiple cameras together for control and monitoring. Standard Camera Link serial
communication 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. Some
documents are available for downloading (example: this document in PDF format).
SW-2000M-CL-65

5.12 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 can
not start again.
5.12.1 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
(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 power connector should now start flashing rapidly. This is the
indication 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.
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.
SW-2000M-CL-65
16
5.12.2 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 power connector should now turn off.
9. Wait for the user interface page to change. Then click on the ‘HOME’ button. The LED
remains off.
10. The camera must next be rebooted. You may power cycle the camera or send the
REBOOT command followed by CONFIRM.
11. Close old communication sessions to the camera and establish new ones as needed.
12. 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 either through the Ethernet interface using the Telnet protocol, or
through the Camera Link serial port using plain ASCII communication. The command line usage
instructions are common to both Telnet and serial bus command line interfaces.
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 Connecting via Camera Link Serial Bus
To connect the camera using the Camera Link Serial Bus:
• Open a serial port. This may be a COM port of your PC or a terminal supplied by the
frame grabber board.
• Select the port settings: 9600 bps, 8 data bits, no parity, 1 stop bit
• Open a serial connection.
6.3 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.

6.4 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 (according to form: LINE IT <time>)
LINE IT 100% (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.

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 command communication. NET settings are saved
automatically.
CS SAVE, LOAD, SAVE2, LOAD2 and FACTORY RESET for saving, loading or restoring the
settings of group B and C.
Group B: Commands affecting exposure
SENSOR for setting sensor responsivity.
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.
Group C: Commands affecting image output format
CL MODE for setting the Camera Link output format.
CL RATE for setting the pixel clock frequency.
READOUT for selecting normal or reverse readout direction.
ROI for selecting Region Of Interest.
BINNING for combining adjacent pixels.
Group D: Utilities
HELP or ‘?’ for list of all commands.
STATUS to display camera information and settings.
VER for displaying firmware versions and camera identifiers.
TEST for selecting test patterns.
REBOOT for restarting the camera.
FIRMWARE UPDATE to change the MCU code.
SW-2000M-CL-65
20
The four groups will be described in detail in the following sections. Most commands display
help on how to use it if 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 or REBOOT
command or power cycling the camera.
NOTE: The CS FACTORY RESET command also saves the new values.

26
7.2 Group B: Commands affecting exposure
7.2.1 SENSOR – selects the sensor mode
The sensor has two possibilities of collecting the light generated charge. The default setting
uses the larger well size for a wider dynamic range and a better signal to noise ratio, which
results in more valid bits. The smaller well is used for higher responsivity, but it brings along
more noise and a smaller dynamic range. The difference of the responsivity between the two
well sizes is approximately a factor of 6. It takes a few seconds to start using the other well
size.
Command
Description
SENSOR ?
Returns the SENSOR setting syntax.
SENSOR
Returns the present setting of SENSOR.
SENSOR DYNAMIC
Sets the sensor into the high dynamic range operating mode.
Larger Quantum Well is in use. This is the default setting.
SENSOR RESPONSIVE
Sets the sensor into the high responsivity operating mode.
Smaller Quantum Well is in use.
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
15.3 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 65,000. 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

Default: 1000.
SW-2000M-CL-65
27
7.2.3
LINE CTRL - Exposure Control
The camera has three exposure control modes: internal, external and mixed, which is a
combined mode of the first two. The start and length of each line, as well as the time that the
light is collected within each line period, follow the same principles regardless of the selected
mode.
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.
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 time always
ends at the same time as the line. The start of the integration time should thus be selected to
match the intended length.
Only two signals or events are needed for these operations. First one is the new line request
and the second one is the signal to start the integration. The source for these events can either
come directly from the input signals of the camera, or from internal timers, or as a
combination of these two.
Command
Description
LINE CTRL ?
Returns the command syntax.
LINE CTRL
Returns the present line control setting.
LINE CTRL EXT
Line rate and integration time are controlled externally by the
host.
LINE CTRL INT
Line rate and integration time are controlled by the camera.
Default setting.
LINE CTRL MIX
Line rate is controlled by externally by the host.
Integration time is controlled internally by the camera.
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 during each scan. The Line IT must be shorter than the Line Period. The actual
integration takes place in the first part of the line period. If the Line Integration time is
commanded to be longer than the Line Period then the integration time will stop at the same
SW-2000M-CL-65
28
time as the line period ends.
The Internal exposure mode cannot be synchronized to an external event. If external
synchronization is needed then External or Mixed mode must be selected for Exposure Control.
7.2.3.2
External exposure control (command: LINE CTRL EXT)
The line period and integration time are controlled externally by the CC1 and CC2 input signals
at the Camera Link connector.
1) CC1. Line control. The time between two rising edges of CC1 defines the line period.
2) CC2. Integration control. There are three special cases of CC2:
A) CC2 constantly low: the integration time will always be the minimum possible.
B) CC2 constantly high: the integration time will always be the maximum possible.
C) The integration time is from any rising edge of CC2 to the next rising edge of CC1 in
all the other cases.

29
7.2.3.3 Mixed mode exposure control (command: LINE CTRL MIX)
The line period is now the time between two consecutive rising edges of the CC1 input signal at
the Camera Link connector.
The integration time is controlled internally by the command LINE IT. The syntax for LINE IT
gives the ability to set the integration time in microseconds or in percentage of maximum
possible integration time.
This mode is useful in situations, where the integration time needs to stay constant regardless
of variations in the line frequency. Each scan would then be triggered from some external
source, while the actual integration time of light would be programmed in advance as an
absolute value. It is of course important to keep the integration time shorter than the line
period. If the line period is shorter than the commanded integration time then the integration
time will be limited by the line period. The use of percentage values for LINE IT command
avoids this, but then the integration time also varies according to the line trigger input (CC1)
frequency.
The integration time is from A to B as set by user by the LINE IT command in advance. If the
integration time is longer than the Line interval, the line interval is used as the integration
time.

7.2.4 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
Description
LINE IT ?
Returns the command syntax.
LINE IT
Returns the present Line Integration setting.
LINE IT <time>
Sets the integration time to <time> in microseconds, where <time> is a
numerical value between 2.00 – 99998.50 with 0, 1 or 2 decimal places.
LINE IT <time>%
Sets the integration time to <time> per cent of the line interval, where
<time> is a numerical value between 0.10 % to 100.00 % (default) with
0, 1 or 2 decimal places.
7.2.5 GAIN - signal gain
The gain control can be used to scale the camera response up or down. In addition to the gain
control the Sensor responsivity can be selected to be Dynamic or Responsive giving a factor of 6
in responsivity due to the difference in quantum well size.
Please note that it is not practical to repeatedly swap the well. Instead, it is better to select it
first and then use only the GAIN command as far as possible.
Command
Description
GAIN ?
Returns the command syntax.
GAIN
Returns the present Gain setting.
GAIN <value>
Sets the Gain to <value>, where <value> is any number between 0.1
and 32 with up to three decimals. The default setting is 1.000
7.2.6
OFFSET - output offset
The value given by this command is directly added to or subtracted from all the pixel values
prior to applying the GAIN.
Command
Description
OFFSET ?
Returns the command syntax.
OFFSET
Returns the present Offset setting.
OFFSET <offset>
Changes the signal level prior to the GAIN stage.
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.
<offset> is a positive or negative integer within a range of -1023 to 1023. This equals ± 25 % of
SW-2000M-CL-65
31
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 being though limited to zero.
7.2.7
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 must be done when the input light distribution is as
uniform as possible in order not to make the FFC correction add errors to the compensation
when activated.
The procedure is then to establish a scene illumination as uniform as possible and having the
intended optics for the application before saving the FFC line graph for the correction. 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 correction must be OFF during calibration.
Command
Description
FFC ?
Returns the FFC command syntax
FFC
Shows whether the correction is ON of OFF.
FFC RUN
When FFC RUN is sent to the camera the actual line image will be
corrected to make the line as horizontal as possible.
FFC ON
Activates the FFC function. If no line graph is saved prior to
activation of the FFC function then no change will be made to the
line image.
FFC OFF
Switches the FFC function OFF. FFC ON command returns the same
correction factors into use, unless a new FFC SAVE command was
given. Default setting.

ROI – region 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. 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.
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 16 pixels. Each region may have individual widths. Changes to
selections are made by defining the complete set again.

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 factor of two.
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 number of first pixel of each pair is always odd.

7.4.4
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. 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
then 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 to look like one completely white line.
The lowest value is actually always the same as what the vertically changing pattern P3 would
have, if it had been started at the same time as P5. Thinking of the visual looks of the pattern
P3, the correct looks of this pattern (P5) can be better understood: the base level or the
darkest parts of the pattern vary just like the vertically ramping P3 would vary. And while the
base level gets brighter then also the horizontal pattern gets tighter as the lengths of those
horizontal ramps decrease making the respective image look like a pattern of higher
frequencies.
SW-2000M-CL-65
36
Command
Description
TEST OFF
No test pattern. Image data originates from the sensor (default).
TEST P1
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 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 of such periods, when advancing
across the 2K pixels. The respective image should thus look like this:
TEST 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 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:
SW-2000M-CL-65
37
TEST 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 ris
e 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
Returns information on the current status of test modes
Note: 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.

9 Software tools for camera communications
The camera can communicate either via its Camera Link port or the Ethernet (10/100) port.
Both communications can be used at the same time. The reply is sent to only the channel,
where the command was received from.
Ethernet port supports multiple telnet sessions at the same time. Standard terminal programs
can be used for control at command level. Default IP address is 10.10.10.10. Telnet Port is
number 23.
JAI provides two control tools as Windows software, as well as web browser access.
9.1 JAI SweepConf
The SweepConf offers a graphical user interface with sliders and pop down menus for the most
common functions as well as a telnet terminal. The same tool works for either Camera Link or
Ethernet.

9.2 JAI Sweep Ethernet Tool
The Sweep Ethernet Tool is a telnet terminal program with possibility to run scripts and to
display single line graphs (average of 32 lines).

9.3 Internal web server
The internal Web server can be accessed by standard web browsers at http://10.10.10.10/
.
It offers some documents for download and is used while updating camera firmware.
