2 Introduction
The CMOS high speed camera MC132x is a high resolution camera with 1280 x 1024 pixel. Benefits of
CMOS technology are high speed, random access to pixels with free programmability and low power.
The camera uses industry-standard C-Mount lenses. The sensor diagonal is 1,25“ with square pixels
measuring 12µm.
Free programmability means that the user is free to define the region of interest by size and position and
the speed of data output. The frame rate can be selected between 25 fps and several thousand fps
depending on resolution and video data width.
With a resolution of 1280 x 1024 pixel, 80 fps can be output via the Gigabit Ethernet Interface. Parameter sets are called “profiles” and stored in non volatile memory.
2.1 Top level specifications
• high resolution: 1.280 x 1.024 pixel CMOS sensor
with 1300 A/D converters
• up to 1.024 gray levels
• up to 80 full frames/s
up to 500 frames/s using data reduction alghorithms
• arbitrary region of interest
• high sensitivity
• 12μm square pixels
• electronic “Freeze Frame” shutter
• low blooming
• programmable via serial link
• patented ImageBLITZ® image trigger
• asynchronous trigger
• download customer specific FPGA preprocessing firmware
• small, compact housing
• wide power supply range
2.2 Electronic „Freeze Frame“ Shutter
Preceding exposure, the contents of all light sensitive elements is cleared. When exposure terminates,
accumulated charge is transferred to an analog memory associated which each pixel. It stays there until
it is read out (and discharged) by the A/D conversion cycle.
As all light sensitive elements are exposed at the same time, even fast moving objects are captured
without geometric distortion.

Initial setup MC132x Users Manual Rev. 0.22
11
5 Initial setup
The MC132x is delivered with initial parameters and therefore does not need to be configured via the
serial link.
5.1 Serial number and firmware revision
Serial number and firmware revision is provided in MC132x non volatile memory. Use :v command
(Read serial number and firmware revision) to read serial number and firmware revision. The serial
number is also marked on the type plate of the camera.
5.2 PowerUpProfile
The PowerUpProfile is the contents of all camera registers to be loaded from non-volatile memory after
power up.
5.3 Camera Profile
The actual set of parameters is called Camera Profile. All changes of parameters by the serial link is
reflected in the Camera Profile. On command the Camera Profile is saved to 8 user profiles or one PowerUpProfile. It is loaded from 8 user profiles or 8 factory profiles or the PowerUpProfile. The camera
profile is volatile and must be stored to the PowerUpProfile to be reactivated on next poer up.
5.4 Factory profile
The factory profile can be read but not written by the user. They are factory preset to the settings described in the next chapter (user profiles).
5.5 User profiles
The user can store up to eight PowerUpProfiles in non volatile memory. All load or write commands
exchange data between the PowerUpProfile and one of the four user profiles.

6 Configuration
The MC132x has 15 FPGA registers, r1..rfh , each 10 bit wide, eight D/A registers, a1..a8, 8-bit wide,
and one clock select register, 4 bit wide. The contents of all the above registers is called a profile. There
is space in non volatile memory for 17 profiles: one PowerUpProfile, 8 user profiles and 8 factory profiles.
Any change of a specific register through the serial interface is immediately processed and written to
the volatile part of the memory and gets lost when power goes down. A command must be used to store
the actual setting in non volatile memory. After power-up the PowerUpProfile is loaded from the nonvolatile to the volatile part of the memory.
A load or write command exchanges data between the PowerUpProfile and one of the eight user profiles. The eight factory profiles can be read but not be written by any command. All values are given in
hexadecimal notation, e.g.: 0xff or 0ffh = 255.
6.1 Commands
ASCII strings are used to change camera parameters. All commands start with a colon, followed by one
selection character and a value in hexadecimal notation with two or three ASCII characters.
After a command has been recognized, processing is immediate, for all commands but the save type
commands (:px). These need a EEPROM write time of app 1ms. An answer is provided with read type
commans (:v, :w, :W) or, if the command “command acknowledge flag” is set, after processing of each
command an ACK or NAK character. Processing of wrong command is stopped immediately on recognizing the error. A new command must start with a colon.

6.4 Image quality
There are three D/A converter to influence image quality: FPN, Gain, and Black up. FPN, Gain and
especially Black might be adjusted if sensor clock changes. All three parameters are stored in nonvolatile memory as part of the selected profile.
6.4.1 FPN
The Fixed Pattern Noise setting reduces the fixed pattern noise that is typical to CMOS sensors. This
level might be changed if the sensor clock frequency is changed. For adjustment set the lens out of focus and to a medium grey level. Lower FPN until a heavy pattern appears. Then raise by a few points.

6.6 Clock selection
The MC132x is equipped with a 2-channel programmable clock synthesizer. One channel controls clock
frequency of the sensor (sensorclock, F
sens
), the other controls the frequency of the pixel clock (pixel-
clock, F
pix
). These independent clocks allow an always optimal ratio depending on the product of (im-
age size x image frequency) and the data rate on the output.
As the sensor outputs 10 pixel per clock a sensor clock of 6.6MHz could be chosen. Because the sensor
can run up to a clock frequency of 66 MHz only 1/10 of the sensors possible speed would be used. To
make use of the maximum sensor clock and maintaining the maximum data rate on the output, just 120
(1280/10 rounded to steps of 10) from the possible 1280 pixel per line can be selected.
Therefore the ratio of F
sens
and F
pix
depends on the selected line length:
F
sens
<= (F
pix
• 1280) / (5 • line length)
or if 100 pixel line length is chosen:
F
sens
= (33 • 1280) / (5 • 100) = 70,4 MHz
As this exceeds the maximum sensor clock frequency, F
sens
is chosen as 66 MHz and F
pix
as 33 MHz.
6.6.1 Arbitrary selection of sensor and pixel clock
Sensor and pixel clock can be set to any value, the product of: (sensor clock • line length/1280) must
always be smaller (about 10%) than the qoutient: (pixel clock / 2).
command :S <x0>
<x
0
> ... 6 characters, as described in chapter Frequency selection
6.6.2 Table selection of clock frequencies
To simplify clock selection when using video data width of 2, clocks can be selected from a table with
15 entries, each entry being optimized for four regions of line length. (see table in 9.4).
Example: 240 < line length <= 640 Pixel, clock selection s9
pixelclock: 30,0 MHz
sensorclock: 11,2 MHz
resulting max. datarate on the 16-Bit output:
30,0 MHz/s * 2 Byte = 60,0 Mbyte/sec.
Configuration MC132x Users Manual Rev. 0.22
This is valid for a line length between 250 and 640 pixel.
command :s <x0>
<x0> ... range 0 ... f (hex)
*
Before selecting the data rate of the camera check
the maximum data rate of the GigE Connection,
which must be higher (or at least the same).
6.6.3 Image Format/Speed change
There are several steps necessary for a change of image format:
i. Disable sensor controller with :r6[4] = 0.
ii. Set image size with (:r1,:r2, :r3, :r4, :r5).
iii. If new sensor clock = old sensor clock:
1. Do not set pixel clock nor sensor clock.
iv. If new sensor clock > old sensor clock:
1. Set new pixel clock (:S6…..), then new sensor clock (:S4….).
v. If new sensor clock < old sensor clock:
1. Set new sensor clock (:S4…..), then new pixel clock (:S6….).
vi. Reenable sensor controller (:r6[4]=1).
6.7 Exposure control
Exposure control is selected with register r6[7..4] and register r2[9..0].
Bit(s) Description
r6[7..4] Type of exposure
r2[9..0] Exposure time
table 6-1
6.7.1 Type of exposure
The MC132x can expose the images synchronous or asynchronous. An external signal on CC1 can be
used to synchronize MC132x cameras to each other or to an external event.
6.7.1.1 Synchronous exposure
Synchronous exposure means that the next image is exposed, while the current image is output. This
mode provides fastest frame rate while maintaining maximum exposure time as long as 1/frame rate. If
an external synchronization signal is input on CC1 its frequency range can be between 30Hz and the
selected free running frame rate. Use MC13xx camera configuration tool for selection.
19
Configuration MC132x Users Manual Rev. 0.22
20
6.7.1.2 Asynchronous exposure
With asynchronous exposure, an external signal starts exposure, and the exposed image is output imme-
diately after the exposure ends. Exposure time is defined either by an internal timer or by the width of
the external EXP (CC1) signal. The time between two consecutive EXP (CC1) edges can be indefinite.
Frame rate = 1/(exposure time + image output time). Image output time equals the selected free running
frame rate. Use MC13xx camera configuration tool for selection.

6.7.3 Synchronous operation without shutter
Without electronic shutter the exposure time is 1 / frame rate.
6.7.4 Synchronous operation with shutter
In the sensor is implemented a freeze frame shutter, which allows to reduce the exposure time in steps
of one line. The minimum value of the exposure time is the duration of 2 line periods, which is determined by the value of r2 (min. 001h).

6.7.5 External synchronisation with synchronous exposure
MC132x cameras can be synchronized to an external signal that is input on the EXP (TRIG) signal. The
strobe output signal of a MC132x “master camera” can be used for that purpose.
See timing diagram:
Synchronous exposure with external synchronisation via TRIG
The cameras frame rate must be set to a frequency slightly higher than the maximum frequency of the
synchronization signal. The minimum frequency should be higher than 30Hz.
Command: :rf<0|1>
<0> ... deselect external sync signal
<1> ... select external sync signal
Response: none
Make sure that a sync signal is present on EXP/CC1 before this command is issued or the “trigger on
CC1” button is pressed on the MC13xx camera configuration tool.
The polarity of the sync signal can be selected with the _Polarity_of_EXP-signal
Configuration MC132x Users Manual Rev. 0.22

6.7.6 Frame rate with asynchronous exposure
The frame rate with asynchronous exposure = Frame rate with synchronous exposure – (1 / exposure
time).
6.7.7 Asynchronous exposure, shutter control by pulse width
This operating mode is selected with register 6:
:r6[7..4] = 0xb
Exposure time depends on the width of the external EXP – signal.
6.7.8 Asynchronous exposure, shutter control by timer
This operating mode is selected with register 6:
:r6[7..4] = 0xf
The asynchronous exposure time is dependent on :r2[9..0]. The exposure timer counts as many lines as
are defined in register :r2[9..0].

6.8 Firmware
The camera possesses programmable devices, which are working with some firmware packages. New
cameras were programmed with all needed firmware packages and will not need any update.
For customized firmware or additional features the camera offers the possibility to update some of the
firmware versions. The procedure of updating depends on the firmware package.
*
Do not update more than 1 firmware at the same time.
In case of updating more than 1 firmware, please start with application program,
then fpga program follows.
6.8.1 Update firmware microcontroller application
The microcontroller works with 2 programs, the bootloader and the application program.
The bootloader is the basic program of the microcontroller, which ensures some basic functions (e.g.
communication, loading application program) and cannot be changed or updated. In standard use of the
camera it will never work in the bootloader program and the version cannot be read out. It’s only used
for updating the application program.
Configuration MC132x Users Manual Rev. 0.22
23
The application program is the active microcontroller program in the camera, which supports communication, data handling and fpga program updates.
See description of update procedure in chapter “Firmware update procedure”.
6.8.2 Update FPGA firmware
MC132x’s logic is integrated into a FPGA (Field Programmable Gate Array), which’s configuration is
stored in an EEPROM. Upon power up or a command the FPGA is loaded with this configuration. Configuration data can be downloaded via the serial interface. Mikrotron may provide configuration files
(*.ibf) on request.
After download of configuration data, this data is permanently stored in EEPROM and the FPGA is
configured with the new data. Besides a power cycle, the :c command can be used to reconfigure the
FPGA with the internally stored configuration data.
See description of update procedure in chapter “
Firmware update procedure”.
6.8.3 Firmware update procedure
Before you disable the loaded firmware please ensure that you have a adequate application firmware
version to load (e.g. MC132x….A202.ibf for application firmware, MC132x…F070.ibf for fpga firmware).
(1) Start camera and test communication, e.g. with tool press “info camera” and wait for response
(serial no. and firmware)
(2) Select in menu “Write” “Write string to camera” and write command
- for application firmware update: :ERASEAPP <ENTER>
- for fpga firmware update: :ERASEEPCS1 <ENTER>
which erases the program and for application firmware will restart the camera.
*
After this command the camera may not be able to deliver any images,
load/send/store register or profile data. The status led of the camera will turn to red.
(3) For application firmware update only:
The camera now starts with the bootloader program. It is displayed during start by the status led
which blink one time during power up.
Test communication, e.g. with MC13xx in menu “Write string to camera” and command :v.
Response (e.g.): B2.02
(4) Select in menu “Write” “Write file to camera” and choose application file MC132x*.ibf) and
open it. The file transfer will start immediately. If the camera recognizes a newfirmware
it will switch off the status led.
*
Download of *.ibf file via serial link takes app. 1,5 - 2 min depending on the used
camera. There should be no loss of power or communication during this time!
(5) Wait until file transfer is finished and the status led turns on. If the upload of the file was
successful, the led will turn to green, otherwise it will be red.
Configuration MC132x Users Manual Rev. 0.22
24
(6) Verify version string by reading serial no. and firmware versions (command: :v). The new
firmware version will be displayed as part of the version string. If the version is identical to
the expected the camera is ready to use for capturing images.
6.8.4 Reset and configuration of the internal FPGA
The command :c executes a reset in the camera. The FPGA will be reconfigured and all internal registers reloaded with the last saved PowerUpProfile. The FPGA is also configured after each power up.
Command: :c
Response: none
6.9 Horizontal pixelbinning
Pixelbinning adds the gray values of two adjacent pixels and outputs it as one pixel with double sensitivity. In X-direction only 512 pixels are needed to cover the sensors full size.
To retain aspect ratio, every second line is discarded, if this feature is not disabled by setting Bit 8 of
register 6 (:r61xx) or vertical pixelbinning is activated.
Command: :r7010
Response: none
If discarding of every other line is not disabled (:r61xx), the contents of :r1 is doubled in camera logic.
To address a specific line on the sensor, the value written into :r1 has to be divided by two and :r3 must
not exceed 1ffh.
Example:
To output 256 lines from line 128, set r1 = 63 and r3 = 255 (=0xff).
6.10 Vertical pixelbinning
Vertical pixelbinning adds the gray values of two superimposed pixel of a column. This doubles sensitivity and vertical field of view. To retain aspect ratio, in addition
horizontal binning must be activated.
To activate, set bit 2 in register 6.
Command example: :r6034
Response: none
6.11 Digital shading correction
For the best possible image quality even at the sensors clock limit, and non uniform lighting, the
MC132x can store gray levels along one line and subtract these from all lines of an image.
To setup shading correction set: :r6[1] = 0.
Then a uniform object should be used together with the desired lighting, exposure mode and time and
lens. The lens should be closed so that the remaining light level along the center line of the image is as
close to zero as possible, but not reaching zero.
Then set :r6[1] = 1.
Configuration MC132x Users Manual Rev. 0.22
25
The gray levels along the center line of the image are saved in volatile memory and then subtracted
form all lines of the following images, as long as this bit remains set.
6.12 Digital gain
Out of the 10-bits sensor data either the most significant 8 bits (gain 1), or bits 8..1 (gain 2), or the least
significant 8 bits (gain 4) are selected.
Command: :r700x
x = 0: gain 1
x = 4: gain 2
x = 8: gain 4
6.13 External clock input
MC132x frequency synthesizer can use the Camera Link® used to synchronize several MC132x to one
master clock.
To activate set Bit 9 of register 7.
Command example: :r7200
response: none
*
If the external reference clock is different from
3.6864 MHz, the codes for the clock synthesizer have
to be recalculated.
6.14 Polarity of EXP-signal
The polarity of the EXP-signal can be positive- or negative active.
Use :r7[8] to select.
Negativ = :r7[8] = 1
Positiv = :r7[8] = 0
Command example: :r7100
Response: none
6.15 Test image
For testing of camera logic and video data transmission, sensor data can be replaced by an internal gray
scale pattern with pixel values of 0..127. Use digital gain command to see pixel values of 0..255.
Command example: :r7040 r7[6]
Response: none
6.16 Image counter
If a sequence of frames is to be recorded for long time at a high frame rate, it can be useful to mark the
images for later identification or check for completeness.
Configuration MC132x Users Manual Rev. 0.22
26
MC132x has a 16-Bit image counter whose count can replace the first two pixel of every image. The
image counter is cleared with every low to high transition of r7[1], the camera enable bit. It is incremented by every new image.
Command example: :r7002 r7[1]
Response: none
6.17 ImageBLITZ® shutter release
ImageBLITZ can replace an external signal (e.g.: a light barrier) to release the shutter. Like a light barrier, ImageBLITZ is used to capture fast moving objects on the exact same position on the image.
Contrary to the light barrier, ImageBLITZ uses the same information as condition to release the shutter
as the then exposed image.
ImageBLITZ defines one specific line or a part of the 1024 lines as trigger window. This is true even if
the selected image size is less 1024 lines or outside of the selected image area.
After activation of ImageBLITZ and after issuing the EXP signal as an enable signal, the MC131x
hardware checks the gray values in the trigger window at a repetition rate that is defined by the exposure time selected with bits 3..0 of r6.
If a selectable number of pixels along that trigger window exceed or fall short of a selectable threshold,
one single image is exposed and output.
To adjust ImageBLITZ®, the trigger line can be superimposed to the image. Within the selected line, 10
pixel are displayed as a dotted black- and white line as long as the selected threshold is not passed.
ImageBLITZ is configured with the registers r8..rCh:
6.17.1 ImageBLITZ® processing
When ImageBLITZ® is activated with :r7
h
[0] = 1:
1. Wait for an active edge on the EXP input.
2. The MC13xx exposes a line, that was chosen with :rC[9..0] and is called trigger line, for an
exposure time defined by :r2[9..0]. It compares the intensity of a group of 10 pixel along the
selected trigger line against an adjustable threshold (:rA
h
[7..0], Range: 255..0).
3. The number of exceedings (:rAh[8] = 0) or fall backs (:rAh[8] = 1), are counted, and the result is compared to a second threshold (:rBh[6..0], Range: 127..0).
4. Each time this threshold is exceeded (release condition); an “inhibit counter” (:rDh[9..0],
Range 1..255) is loaded.
5. The inhibit counter” :rDh[9..0] is counted down, each time the “release condition” was not
reached. Once this “inhibit counter” has expired, a new image is exposed and output.After
image is output, repeat at 1.
6.17.2 ImageBLITZ® programming
ImageBLITZ® is programmed by registers r8..rDh and activated with r7[0].
Configuration MC132x Users Manual Rev. 0.22
6.17.2.1 Address of trigger line

The trigger line is displayed as dashed, black and white line. One dash has a length of 10 pixel. The
trigger line is only displayed in parts of the line where the pixel fulfill the trigger requirements.
Under normal operation conditions the trigger line will be visible only in parts. The number of dashes
may be counted and used for the setting of register rBh.

The Release Inhibit function is defined with :rD
h
. It tells ImageBLITZ how often sequentially the “re-
lease condition” must not be met, before an image is output.
This feature allows to trigger an object only once on the dark- to bright edge of the scene. This avoids
retriggering, once the trigger condition was met and the object is still visible within the triggerline after
the image has been output.

8.2 Lens adjustment
8.2.1 Lens adaption
In dependence of the camera model the MC132x camera are prepared for either C-mount or F-mount
connection (see table
overview of cameras).
Camera types with F-mount adaption may be converted to C-mount adaption by exchanging the lens
mount flange of the camera, which is attached with 4 screws. The C-mount lens flange is not scope of
delivery of the F-mount camera types and is offered separately.
8.2.2 Adjustable lens adapter, only for camera models with C-mount flange
For fine adjustment of the focal length a lens adapter with an adjustment range of ± 1 mm is provided.
Use the three screws nearby the sensor window to fasten the lens adapter after a proper adjustment together with the chosen lens.
8.2.3 Lens selection for camera types with C-mount flange (see table
overview of cameras)
Due to the size of the sensor use C-Mount lenses with the largest possible optical diameter or an adapter
for lenses like F-Mount, especially for lenses with a focal length < 25mm..

Before applying power to the camera we strongly recommend to verify the used pins of the
power connector, the polarity (+/-) of the leads and the supply voltage.
The camera may only be used with a supply voltage according to the camera specification.
Connecting a lower or higher supply voltage, AC voltage, reversal polarity or using wrong
pins of the power connector may damage the camera. If doing so, the warranty will expire
immediately.

9.4 Frequency selection
Depending on the selected line length and the datarate of the GigE interface the frequency selection
table can provide an optimal ratio of sensor /pixel clock. The pixel clock is only dependent on the
selected step and not on the linelength.
The sensor clock is dependent on both the selected step, the line length and the data width. The tables
show the selectable frequencies and the correponding codes to program the synthesizer accordingly.
9.4.1 Table of clock frequency codes
For free programming of the clock frequencies of pixel and sensor clock the following table can be
used. All codes in the table show the code for sensor clock. The code for pixel clock is the same but
starts with “6”.
Example: Adjustment 1 MHz
Command for sensor clock: :S41bb0b
Command for pixel clock: :S61bb0b
*
Pixel and sensor clock must be adjusted in dependence of the used camera mode as described
in chapter frequency selection. Undefined settings may lead to functional faults or can damage the camera.
