Data content:
Description of the status byte
Notice!
At a resolution of 1mm and with 24 position bits, a maximum position of up to 16'777'215mm
can be transmitted.
Notice!
The P00 data bit corresponds to the LSB
,
the P23 data bit corresponds to the MSB.
Response to marker information
If information consisting of one of the capital letters A / B / C / D / Z and two digits is read,
the M bit for the recognition of the marker information is set in the status byte. The S-Bit 0
control bit can now be used to retrieve the marker information. If the marker info is not
requested, the position continues to be output.
The marker information is output as an ASCII hex value in three bytes.
