RS422 Connection with USB Converter IF2001/USB
Cross the lines for connections between sensor and PC.
i
Disconnect or connect the D-sub connection between RS422 and USB converter when the sensor is disconnected from power
supply only.

Analog Output
The sensor provides a current output 4 ... 20 mA.
i
The output may not be continuously operated in short circuit operation without load resistor. The short circuit operation leads to
durable thermal overload and thus for automatic overload shutdown of the output.
Connect the white and the blue wire on the sensor to a measuring device.
