Response telegram structure
Description
Position data
The position data are output in two's complement as a 32-bit signed integer value by
default in millimeters with a resolution of 1 mm (see chapter 8.5.2 "Position detection")
The P00 data bit corresponds to the LSB, the P31 data bit corresponds to the MSB.

MM Marker bar code present 1 = The content of a marker bar code is in the memory
0 = No content of a marker bar code in the memory
4
SLEEP Standby state 1 = Device is in Standby mode
(see request telegram)
0 = Device is in positioning mode
