9. Value Output
The optoNCDT 2300 outputs the measurements are either via the RS422 or Ethernet. Both output types can not be used simultane-
ously.

9.1 RS422
The digital measurement values are issued as unsigned digital values (raw values). 16 Bit per value are transmitted. One or two 16-bit
values are transmitted. Examples: a displacement value or two displacement values or a displacement value plus an optional reading
or two optional readings. The formula also applies to values that are encoded with 18 bits, see Chap. 8.3.
