A 5.4 Measured Value Format
A 5.4.1 Structure
The structure of measured value frames depends on the selection of the measured values or on the selection of a preset.
In the following overview, you will find a summary of commands which you can use to query the available measured
values via RS422.
Chap. A 5.3.13.2 OUT_RS422
Chap. A 5.3.13.3 META_OUT_RS422
Chap. A 5.3.13.4 GETOUTINFO_RS422

A measured value frame is built dynamically, i.e., values not selected are not transmitted.
A 5.4.2 Video Signal
The video signals that have been calculated in the signal processing process can be transmitted. A video signal com-
prises 512 pixels. One pixel is described by a 16-bit word. The value range used is 0...16383.
There are five accessible video signals:
- Raw signal
- Dark corrected signal
- Light corrected signal
You can query the dark value table and the light value table with the commands
DARKCORR_PRINT LIGHTCORR_PRINT
and
Pixel 0
Raw signal, 16 bit
Dark corrected signal, 16 Bit
Light corrected signal, 16 Bit

A 5.4.3 Exposure Time
The output of the exposure time via the RS422 interface is done with a resolution of 100 ns. The data word is 18 bits
wide.
