Multi-Function Connection I/O

Interfaces and signals for external control of the sensor or for outputting sensor states and data are provided via the
multi-function connection. The four connections operate either as inputs or outputs.

Fig. 13 Pin assignment of the multi-function connection
The multi-function connection is a 12-pin M12 round connector. The connecting line is intended to be up to 35 m long;
however, the cable must be shielded at any length. Micro-Epsilon recommends using the PCR3000-x multi-function
cable.
5.2.4.1

Digital Signals

The four digital connections of the multi-function interface provided can operate optionally as inputs or outputs. They are
configured using the software. All digital ports share a joint ground GND GPIO.
External auxiliary power (max. 30 V) is required to use the outputs.
The digital signals are not suitable for brief signal pulses or time-critical signals. The exception is port 1, which, when
configured correctly, can be used as a hardware trigger to start a measurement and is directly connected to the se-
quence control in the sensor.
The functionality of the digital signals can be programmed, see
switched for the inputs and outputs. Internal sensor signals can be assigned to the digital outputs, for example, to con-
trol additional connected devices.
