Data Record
The DMC-2x00 can provide a block of status information with the use of a single command, QR. This
command, along with the QZ command can be very useful for accessing complete controller status.
The QR command will return 4 bytes of header information and specific blocks of information as
specified by the command arguments:
QR ABCDEFGHST
Each argument corresponds to a block of information according to the Data Record Map below. If no
argument is given, the entire data record map will be returned. Note that the data record size will
depend on the number of axes.
