Operating instructions Distance measuring device DL100 Pro – RS-422
RS-422 interface
10 RS-422 interface
10.1 Basics
The serial interface RS-422 of the distance measuring device can be
used to read the measured data and defined operating data and change
parameters. All data are transferred as ASCII characters.
Measured data like distance or combined distance/speed values and
operating data like internal temperatures are transmitted on request.
Distance values and combined distance and speed values can be
transmitted in a continuous data flow.
