Operation and Communication
You can define the structure and content of the response telegram using the configuration
software
Vision Configurator
. This may include position data in an X- and Y-direction as well
as speed and diagnostic data. Make sure that the required settings have been configured,
transmitted to the reader, and stored there. The factory default structure of the response
telegram is as follows:

Status bits
Note!
The number of position bits required in the X-direction depends on the track length of your
system and the required position resolution.
Example:
max. track length = 300 m, required position resolution = 1 mm.
19 bits are enough to display the X position. You can therefore assign 6 bits to display
additional data.
