The sensor can continue to supply measured values to the RS422 output even while the sensor is communicating.

The IF2001 converter from MICRO-EPSILON, which is connected to the sensor via the PC1100-x standard cable (also
optional), is suitable for data exchange with a PC,

. The IF2008/ETH is suitable for recording data in a syn-

chronized manner from multiple sensors. You can find more information in the descriptions of the IF2008/ETH interface
card and the relevant MEDAQLib driver program.
You can find the current program routine at:

8.3

Resetting the Baud Rate

You can reset the baud rate to the factory setting when
you start the sensor. To do this, half the supply voltage
must be applied to the trigger input. This will reset the
sensor to 115200 baud.
This means that, with the 47 kOhm internal pull-down re-
sistor, you simply have to connect the

TRIG

connection

to

via a 47 kOhm resistor.
