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. Parame-
ter 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 Pow-
erUpProfile. 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 de-
scribed 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 pro-
files.
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 non-
volatile to the volatile part of the memory.
A load or write command exchanges data between the PowerUpProfile and one of the eight user pro-
files. 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 recog-
nizing the error. A new command must start with a colon.

6.3.3 Load factory profile
The eight factory profiles can be read but not changed by the user.
Command: :f<n> <n> = 0 ... 7
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 non-
volatile 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 fo-
cus and to a medium grey level. Lower FPN until a heavy pattern appears. Then raise by a few points.
Command: :a1<x1x0><x1x0>: Range, typ. 55h ... 80h
Response: none
6.4.2 Gain
This is the threshold for the A/D converters. Its standard value is 66h for app. 1V. One step is app.
10mV. To increase the gain the value of a2 must be lowered.
Command: :a2<x1x0> <x1x0>: Range,
typ. 30h ... 80h
6.4.3 Black Level

6.6 Clock selection
The MC132x is equipped with a 2-channel programmable clock synthesizer. One channel controls clock
frequency of the sensor (sensorclock, Fsens), the other controls the frequency of the pixel clock (pixel-
clock, Fpix). 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 Fsens and Fpix depends on the selected line length:
Fsens <= (Fpix •1280) / (5 •line length)
or if 100 pixel line length is chosen:
Fsens = (33 •1280) / (5 •100) = 70,4 MHz
As this exceeds the maximum sensor clock frequency, Fsens is chosen as 66 MHz and Fpix 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>
<x0> ... 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.

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.
The following registers select exposure type:

6.7.2 Frame rate with synchronous exposure
The frame rate with synchronous exposure is direct proportional to the selected number of lines.
The time for one line is:
Tzz = 1/Fsens •136 [sec]
Tzz ...time/line
Fsens... Sensorclock
Frame rate: = 1 / (time/line •number of lines+1) or:
= Fsens/ (136 •(r3[9..0] +2))

ing table: image size
