Displacement values, differential values, intensity
An intensity for each selected displacement, if selected, is transmitted.
Maximum 2 measurement values can be transmitted by direct reflection.
Displacement or differential value
Ethernet: The displacement values or the differential value were shown as a signed integer value (32 bit) with a resolution of 1 nm.
RS422: The displacement values or the differential value were shown with a resolution of 16 bit, while the value range is 18 bit. This
means, that even D16 and D17 stand in the H-byte, when through a denser medium with a refractive index >1, maximal 4, is mea-
sured through, see Chap. 8.3.
