2 Introduction
The CMOS high speed camera EoSens is a high resolution camera with 1280x1024 pixel.
Benefits of CMOS technology are high speed, random access to pixels with free programma-
bility and low power.
The camera uses industry-standard C-Mount or F-Mount lenses. The Sensor diagonal is 22.9
mm with square pixels measuring 14 µm.
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 1 fps and sev-
eral thousand fps depending on resolution and video data width.
With a resolution of 1280 x 1024 pixel, 500 fps (MC1362/63) can be output via the “full Cam-
era Link®” Interface.
2.1 Top level specifications
 High resolution: 1280x1024 pixel CMOS Sensor
 up to 1024 gray levels (10bit resolution)
 up to 110 full frames/s for MC1360/61
 up to 500 full frames/s for MC1362/63
 arbitrary region of interest
 very high Sensitivity
 14 µm square pixels
 electronic “Freeze Frame” shutter
 low blooming
 programmable via CameraLink® serial interface
 asynchronous trigger
 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.

3 Hardware
3.1 Camera Link® interface
Camera Link® is designed for digital cameras in machine vision applications. A “Full Camera
Link®” interface can transfer up to 80 bits of data at a rate of max. 680 Mbytes/sec.
3.1.1 Serial interface
The communication via the serial interface is incorporated in the “Base Camera Link® inter-
face.
3.2 Power supply
The camera needs a DC supply voltage between 8 … 24V at a power consumption of 4.5 Watt
max.
See also Connector pinning.

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.
3.3 Status LED
A dual color LED on the camera backplane shows the operating condition of the EoSens.
LED orange... The EoSens is configuring the internal FPGA. No other activity is possible.
LED green... The EoSens is fully operational.
LED off... If LED is off, despite the camera is powered, data is stored to the internal
EEPROM. No other activity is possible.
LED red... The microcontroller detected a wrong checksum or the FPGA could not be
loaded because of wrong FPGA configuration data. The camera is not
functional. Try to reload configuration data.
LED red blinking... Data is loaded to microcontroller or FPGA from the PC or the camera veri-
fies the checksum. No other activity is possible.

5 Initial setup
The EoSens 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 EoSens non volatile memory. Use :v com-
mand (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 content of all camera registers to be loaded from non-volatile mem-
ory 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 pro-
files or the PowerUpProfile. It is loaded from the PowerUpProfile, 8 user profiles or 8 factory
profiles. The camera profile is volatile and must be stored to the PowerUpProfile to be reacti-
vated on next power up.
5.4 Factory profiles
The factory profiles can be read but not written by the user. They are factory preset to the set-
tings described below.

Configuration EoSens CL Camera Manual

6 Configuration
The content of all EoSens registers is called a profile. There is space in non volatile memory
for 17 profiles: The 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 PowerUp-
Profile is loaded from the non-volatile to the volatile part of the memory.
A load or write command exchanges data between the CameraProfile 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.
Commands
ASCII strings are used to change camera parameters. All commands start with a colon fol-
lowed by the command character. Note that the commands are case Sensitive. The baudrate
can not be saved. Therefore the camera always defaults to 9600 baud after power on or reset.
After a command has been recognized, processing is immediate for all commands but the
save type commands (:p and :o). These need a EEPROM write time. An answer is provided
with read type commands (e.g. :v, :w), or, if the command acknowledge flag is set, after proc-
essing of each command an ACK or NAK character. Processing of wrong commands is
stopped immediately on recognizing the error. A new command must start with a colon.
All unknown commands will return NAK. After the colon the maximum time between the char-
acters must not exceed 2.7 sec., else the command will terminate with NAK. This prevents the
parser from hanging in the input if a command is not entered complete.
Most of the commands can return the actual value by sending '?' as parameter. Some com-
mands then also return the actual value range.

6.3.1 Write user profile, command :p
The actual Profile is transferred to one of the eight user profiles or the PowerUpProfile. Profile
“c“ is the PowerUpProfile.
Command: :p<n> <n> = 0 ... 7, c

Issue this command only, if the profile was suc-
cessfully tested.
6.3.2 Load user profile, command :g
Load one of eight user profiles or the PowerUpProfile to the actual camera profile. Profile “c“ is
the PowerUpProfile
Command: :g<n> <n> = 0 ... 7, c
6.3.3 Load factory profile, command :f
The eight factory profiles can be read but not changed by the user.
Command: :f<n> <n> = 0 ... 7

6.4 Output mode
6.4.1 Output mode, command :M
Command: :M<x> <x> = 0…6
or: :M?
Response: --* * ACK/NAK if acknowledge on
or: <x> <x> = actual value
Description: This command selects the camera output mode. For example the
mode 0 delivers 2 taps with 8 bit.
Mode Description CL-configuration Remark
0 2 x 8 base
1 2 x 10 base
2 16 x 1 base optional feature, binarization
3 2 x 8 base optional feature, mask mode
4 4 x 10 medium
5 8 x 8 full
6 10 x 8 full
6.5 Image quality
6.5.1 Digital gain, command :D
Command: :D<xxxx> <xxxx> = 0400 ... 1000h
or: :D<x> <x> = 0
or: :D?
Response: --* * ACK/NAK if acknowledge on
or: <xxxx> <xxxx> = actual value
Description: The digital gain can be set from 0400h which is equivalent to gain 1x to
1000h which is equivalent to gain 4x. Setting the gain to 0 switches off the
correction completely.
6.5.2 Blacklevel, command :k
Command: :k<xx> <xx> = 32 ... C8h
or: :k?
Response: --* * ACK/NAK if acknowledge on
or: <xx> <xx> = actual value
Description: This command adjusts blacklevel. The value 80h is the factory calibrated
default. Increase or decrease this value slightly to adjust blacklevel.

6.5.3 FPN correction, command :N
Command: :N<x> <x> = 0 or 1
or: :N?
Response: --* * ACK/NAK if acknowledge on
or: <x> <x> = actual value
Description: With this command the column FPN (fixed pattern noise) correction can
be activated or deactivated. At the beginning of each frame, before visible
lines are read out, a fixed voltage is applied at the columns. These values
are read out like real data and are stored inside the camera. When FPN
correction is enabled the stored value is subtracted of each pixel. The ad-
vantage is a more homogeneous picture but with a limited dynamic.
Note: This noise is not dynamic but fixed (as the name says). That’s a typical
effect of a CMOS sensor. But the fixed pattern makes it easy to eliminate
this noise completely. The camera does only a column correction. If an
accurate pixel correction of the full frame is required this must be done by
the framegrabber or in the imaging software. To do this it’s best to switch
off the camera’s FPN correction to get the original dynamic. Then a com-
plete image of a uniform area must be stored as a reference. This values
must be subtracted for each pixel of the frame and the noise will disap-
pear.

6.6 Image size and position
Image size and position within the Sensor is defined by four parameters:
Block Description Value
<aaa> Address of first pixel (x-start) 0 ... 4FEhex (modulo 24)
<bbb> Address of first line (y-start) 0 ... 3FEhex
<ccc> x-width (x-width) 2 ... 500hex (modulo modus)
<ddd> y-height (y-height) 1 ... 400hex
6.6.1 Setting the ROI, command :d
Setting image size and position - region of interest (ROI):
Command: :d<aaa><bbb><ccc><ddd> values as described above
or: :d?
Response: --* * ACK/NAK if acknowledge on
or: aaabbbcccddd actual value
Note: The x-start is rounded down if not modulo 24. The x-width has the modulo
of the actual mode, e.g. 2, 4, 8 or 10. If the value does not fit the modulo
the command will return NAK.
The ROI change time is 18ms including command transfer at 115kBaud.
The new ROI is synchronized to the next frame so there is an additional
delay of max 1 frameperiod.
For fast tracking purposes see also the ROI move mode.

6.6.2 Setting multiple ROIs, command :L
Command: :L<z><xxx><yyy> <z> = 1…3 window to set
<xxx> = 0…4fe x-start
<yyy> = 0…3fe y-start
or: :L<z>? show actual start of window <z>
or: :Ln<a> <a> = 0…3 windows to activate
or: :Ln? show number of active windows
Response: --* * ACK/NAK if acknowledge on
or: xxxyyy actual value
or: a
Description: With this command multiple ROIs are activated and controlled. EoSens
allows to simultaneously choose up to three individual RoIs within the
complete frame range. Thus, multiple objects can be captured independ-
ently at the same time. Normally only one window is active. This is the de-
fault of a=0. With a>1 up to 3 additional windows can be activated. So a
total of maximal 4 windows can be active. Each window can have its own
start address. The size of the additional windows is the same as the main
ROI.
Note: The x-start has a modulo of 48 beginning with 0 or 24 depending on the
main ROI. If multiple ROIs are active also the main ROI is locked to
modulo 48. Start addresses not fitting this modulo will be automatically
rounded by the camera and can be checked with the read command. Note
also that when changing the size of the main ROI the additional ROIs will
be changed automatically. So take care that these ROIs will fit into the
sensor size. Also the maximum framerate will decrease if multiple win-
dows are active.
Remark: This mode can not be combined with ROI move mode, x- or y- invert
mode and mask mode.
