Question:

In what format are the single images stored?

Answer:

The  LuxWare  configuration  tool  offers  four  standard  formats  for  storing  single  camera
frames:

*.TIFF format: the lowermost eight bits (MSB) per pixel are stored.

*.PNG format: In 8-bit images, the lowermost eight bits (MSB) of each pixel are stored;
in 10/12/14/16-bit images, 16 bits (MSB) are stored.

*.PGM format: In 8-bit images, the lowermost eight bits (MSB) of each pixel are stored;
in 10/12/14/16-bit images, 16 bits (MSB) are stored. In addition, the PGM file contains a
file header in which, among others, the pixel format and the image geometry are stored.

*.PPM format: the RGB values are stored as ASCII data.

Question:

How does the LuxWare software communicate with the camera?

Answer

:

The software uses a scriptable ASCII log; for the description see chapter 'Description of the
LOGLUX

 i5 CL communication log'.

Question: What  does  the  error  message  „Invalid  value  read,  maybe  camera  not  initialised“

mean?

Answer

:

A  register  read  by  the  LuxWare  configuration  software  contains  an  invalid  value.  In  this
case,  you  should  initialize  the  active  profile  using  the  values  of  one  of  the  pre-defined
profiles, or copy the values of another profile to the active profile.

Question: Is framegrabber 'xyz' supported?

Answer:

CameraLink

  framegrabbers  are  supported  in  two  ways.  KAMERA  WERK  DRESDEN

GmbH  offer  several  CameraLink

  framegrabbers  which  are  supported  by  the  LuxWare

configuration  tool.  Other  CameraLink

  framegrabbers  may  be  used  to  configure  the

LOGLUX

  i5  CL  camera  by  means  of  the  INI  file  of  the  LuxWare  configuration  tool  (see

Adding a non-supported CameraLink

 framegrabber').

Question

: Why does my supported framegrabber communicate so slowly or faultily?

Answer:

Depending  on  the  framegrabber  used,  more  or  less  faults  occur  as  regards  the
framegrabber's  support  of  the  serial  API.  This  may  result  in  a  slow-down  of  the
communication  or  in  a  faulty  communication  with  the  camera.  The  remedy  is  to  use  the
serial  COM  port  of  the  LOGLUX

  i5  CL  camera  (see  'Using  software-supported

framegrabbers on the serial COM port of the LOGLUX

 i5 CL camera ').

Question: My LOGLUX

 i5 CL camera is connected but not detected. Why?

Answer:

First check if the host system (PC/IPC) and  camera  as  well  as  camera  and  power  supply
unit are properly connected. Moreover, make sure the system load on the hardware of the
host  system  is  as  low  as  possible  during  the  LOGLUX

  i5  CL  search  process  since  too

heavy a load might result in an exceeding of the communication time.

Adding a non-supported CameraLink

 framegrabber

If your CameraLink

 framegrabber is not supported by the  LuxWare configuration tool,  the INI file  of

the software may be used for configuring the LOGLUX

 i5 CL camera.

To this end, modify the INI file 'LuxConfig.ini' - it is found in the same directory as the configuration tool
-  as follows, and add the following lines, using a simple text editor:

[GenericCameraLinkDevice]
InterfaceLibrary=clser<xxx>.dll
MinPortId=<MinPort>
MaxPortId=<MaxPort>
Description=<My own powerful framegabber>
