Introduction1.
The CMOS high speed camera HXC13 is a high resolution camera with 1280x1024 pixel.
Benets of CMOS technology are high speed, random access to pixels with free program-
mability and low power.
The camera uses industry-standard C-Mount, F-Mount or M42 lenses. The sensor diago-
nal is 22.9 mm with square pixels measuring 14 µm.
Free programmability means that the user is free to dene the region of interest (ROI) by
size and position and the speed of data output. The frame rate can be selected between
1 fps and several thousand fps depending on resolution and video data width.
With a resolution of 1280 x 1024 pixel, 500 fps can be output via the “Full CameraLink®”
Interface.

Preceding exposure, the contents of all light sensitive elements is cleared. When ex-
posure 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.

Notice
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 speci-
cation (8 VDC .. 24 VDC). 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.

LEDSignaling2.5.
The operation conditions of the camera are signaled by the dual color LED on the
backside of the camera.

Getting Started3.
Before starting to operate the camera, make sure that the following equipment is
available:
Baumer HXC13 camera▪
required lens▪
Baumer Software CD▪
Image processing system, e.g.: PC and Software▪
1 CameraLink▪® cable (2 for Full CameraLink® operation)
1 Power supply 12VDC, 0.75A min▪
1 power cable▪
Initial Setup4.
Baumer HighSpeed cameras are delivered with initial parameters and therefore do not
need to be congured via the serial link.
SerialNumberandFirmwareRevision4.1.
Serial number and rmware revision is provided in the cameras non-volatile memory.
Use :v command to read serial number and rmware revision. The serial number is also
marked on the type plate of the camera.
PowerUpProle4.2.
The PowerUpProle is the content of all camera registers to be loaded from non-volatile
memory after power up.
Cameraprole4.3.
The actual set of parameters is called Camera Prole. All changes of parameters by the
serial link is reected in the Camera Prole. On command the Camera Prole is saved to
8 user proles or the PowerUpProle. It is loaded from the PowerUpProle, 8 user proles
or 8 factory proles. The camera prole is volatile and must be stored to the PowerUp-
Prole to be reactivated on next power up.
FactoryProles4.4.
The factory proles can be read but not written by the user. They are factory preset to the
settings described below.

Conguration5.
The content of all camera registers is called a prole. There is space in non volatile mem-
ory for 17 proles: The PowerUpProle, 8 user proles and 8 factory proles.
Any change of a specic 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 PowerUpProle is loaded from the non-volatile to the volatile part of the memory.
A load or write command exchanges data between the CameraProle and one of the eight
user proles. The eight factory proles can be read but not be written by any command.
All values are given in hexadecimal notation, e.g.: 0xff or 0ffh = 255.
Commands5.1.
ASCII strings are used to change camera parameters. All commands start with a colon
followed by the command character.
Notice
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 command (:p). This needs a EEPROM write time. An answer is provided with
read type commands (e.g. :v, :w), or, if the command acknowledge ag is set, after pro-
cessing 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
characters 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
commands then also return the actual value range.

(Except of mode 6 with 75MHz). With this setting the full speed
of the camera can be achieved. The clock can be adjusted in 5
MHz steps from 60…80MHz.
Application Under some circumstances it is helpful to reduce the clock. This
is the case if the framegrabber can’t accept fast pixelclock or
if a long or poor cable is used. Note that a reduced pixelclock
results in a lower maximal framerate. This can be checked with
the framerate command.
Notice
In mode 6 the value 50hex is not valid.

ImageQuality5.6.
Digital Gain5.6.1.
Command :D
<xxxx>
<xxxx> = 0400 ... 1000hex
:D
<x>
<x> = 0
:D?
Response --* * ACK/NAK if acknowledge on
<xxxx>
current value
Description The digital gain can be set from 0400hex which is equivalent to
gain 1x to 1000hex which is equivalent to gain 4x. Setting the
gain to 0 switches off the correction completely.
Blacklevel5.6.2.
Command :k
<xx>
<xx> = 32 ... C8hex
:k?
Response --* * ACK/NAK if acknowledge on
<xx>
current value
Description This command adjusts blacklevel. The value 80hex is the factory
calibrated default. Increase or decrease this value slightly to
adjust blacklevel.
FPN Correction5.6.3.
Command :N
<x>
<x> = 0 or 1
:N?
Response --* * ACK/NAK if acknowledge on
<x>
current value
Description With this command the column FPN (xed pattern noise) cor-
rection can be activated or deactivated. At the beginning of
each frame, before visible lines are read out, a xed voltage is
applied at the columns. These values are read out like real data
and are stored inside the camera. When FPN correction is en-
abled the stored value is subtracted of each pixel. The advan-
tage is a more homogeneous picture but with a limited dynamic.
Notice
IThis noise is not dynamic but xed (as the name says). That’s a typical effect of a
CMOS sensor. But the xed 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 complete 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 disappear.

Image Size and Position5.7.
Image size and position within the Sensor is dened by four parameters:
Block Description Value Range
<aaa>
Address of rst pixel (x-start) 0 ... 4FEhex (modulo 24)
<bbb>
Address of rst line (y-start) 0 ... 3FEhex
<ccc>
x-width 2 ... 500hex (modulo modus)
<ddd>
y-height 1 ... 400hex
SettingtheRegionofInterest(ROI)5.7.1.
Setting image size and position - region of interest (ROI):
Command :d
<aaa><bbb><ccc><ddd>
values as describes above
:d?
Response --* * ACK/NAK if acknowledge on
aaabbbcccddd
current values
Notice
The x-start is rounded down if not modulo 24. The x-width has the modulo o f
the actual mode, e.g. 2, 4, 8 or 10. If the value does not t the modulo the command will
return NAK.
The ROI change time is 18 ms including command transfer at 115 kBaud. 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.
