Camera Revisions
B.1 General Remarks
This chapter lists differences between the revisions of the camera models.
Always the newest camera revision is shipped if not otherwise mentioned by the customer. If a
previous version is required then this must be clearly mentionend on the purchase order.
The version of your camera is stored in the property
uCRevision
(in category
Info
/
CameraInfo
,
set visibility to Expert). It is a number with at least 5 digits. The two rightmost digits are the
build number, the next two digits (counting from the right side) are the minor revision number
and the remaining digits are the major revision number.
uCRevision =10203 would therefore
indicate the version 1.2 (build 3).
B.2 Glossary of terms used in revision table
List of terms used in the revision tables in this chapter:
Standard Trigger Standard trigger features. Trigger Source: Free running, Software Trigger,
Line1 Trigger, PLC_Q4 Trigger. Exposure Time Control: Camera-controlled,
Trigger-controlled. Additional features: Trigger Delay, Burst Trigger and Strobe.
A/B Trigger Bug In the affected revisions, the bug is present in single A/B trigger mode: when
the encoder position moves back and forth by a small amount, the
EncoderCounter
is
incremented and the decrement is sometime omitted, leading to a wrong EncoderPosition
indication in the camera. Therefore the single A/B trigger mode should not be used in the
affected versions. A workaround to have the same behaviour as the single trigger mode,
but without the bug: use the double A/B mode and double the value of
ABTriggerDivider .
DataFormat3D
DataFormat3D
introduced enables the output of 8 bit intensity values (
LL_HEIGHT
)
instead of 4 bit values ( DataFormat3D =1). In this mode the laser line width ( LL_WIDTH ) is
reduced to 4 bits instead of 6 bits. The position of these parameters in the 3D data is also
modified if
DataFormat3D =1. DataFormat3D =0 is the default mode which is also the mode
used in revisions that don’t have the DataFormat3D feature.
Status information Status information fields (Section 5.10): IMG_CNT[23:0], ENC_POS[23:0],
M_TRIG[7:0], M_FC_TRIG[7:0]
Moving ROI Bug Moving ROI has a bug in the laser finder feature in the camera versions 3.1.
V3.1 behaves differently when using PeakFilter and Moving ROI: peak filter does not have
an effect on moving ROI, but only on the 3D data.
High speed Bug
In Highspeed mode was a bug calculating Peak0_3DH. Also, when using
Highspeed mode moving ROI is not available. This modifications are implemented in
camera version V3.3 and higher
