In case you experience aborted frames, the network traffic is too high and is not
suitable for reliable operation.

4.5.5.

Expert Settings

When the

Expert Settings

button on the first tab is pressed, additional options

are displayed, intended for experienced users only.

Initial Settings Tab

Use Live Mode for Free-run

– the normal single buffer mode is used, i.e. not

using a real-time module (see the documentation for programmers for details).

PauseOnRequest mode for Free-run

– the real-time module uses acquisition

without software triggering each image.

Reload Camera Definitions

– when you make changes in the database of camera

definitions by the

Camera Editor

, you can reload the database without need to

restart the PicSight demo program. This helps to see immediately the impact of
changes you made.

Color Correction Tab

This tab shows additional possibilities of conversion of color images.

Note that some of the functions demonstrated here may not be supported in our
libraries yet and will be available gradually.

4.6.

Firmware Update and Recover Mode

4.6.1.

The Firmware Update

The camera firmware can be updated from a PC with Windows. The update tool
is included with LV-SDS since the version 1.96.169. It is located in the BIN
folder of LV-SDS and its name is

PicSightGigEUpdater.exe

. The packages with

the updated software can be downloaded from

www.leutron.com

.

During  the  update  process  the  needed  files  are  first  fully  uploaded  to  the
PicSight flash memory, and then, after successful upload, the system is switched
from  the  previous  version  to  the  new  one.  Thus,  if  the  upload  of  files  fails  for
any reason, the original system remains untouched and the firmware update can
be  done  again  after  PicSight  reboot.  However,  in  case  the  failure  in
communication  would  happen  during  the  system  switching  (which  takes  only  a
very small part of the update process, so the probability that it happens is also
small),  the  PicSight  may  get  into  a  status,  in  which  it  is  not  able  to  boot
anymore. In such case the

Recover Mode

must be used to boot.
