Conversion of the binary data format
For conversion purposes the H-Byte, M-Byte and L-Byte must be identified on the basis of the two first bits (flag bits), the flag bits
deleted and the remaining bits compiled into a 16 or 18 bit data word.
Result of conversion
D17 D16 D15 D14 D13 D12 D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
Conversion must be done in the application program. D16 and D17 are used only for measurements in optically heavy materials with
a refractive index greater than 1 and to interpret the error codes.

The sensor continues to deliver measurement values to the RS422 output even while communicating with the sensor.
For the data transfer with a PC the MICRO-EPSILON IF2008 PCI BUS interface card is suitable. This can be connected to the sensor
via the PC2300-x/IF2008 interface cable, which is also available as an option. The IF2008 combines the three bytes for the data word
and saves them in the FIFO. The 16 bits are used for measurement values and error values. As standard, the IF2008 interface card is
suitable for connecting two or (via a Y intermediate cable available as an option) up to four sensors plus two additional incremental
encoders. For further information, please refer to the descriptions of the IF2008 interface card and associated MEDAQlib driver pro-
gram.
