The interface is located in the cable entrance area on the back of the device.
Standard configuration of the RJ45 according to IEEE 802.3.
LED green: network connection
LED yellow: data exchange via Ethernet (sending or receiving) is taking place.
12.3.6 Service voltage supply power jack, 2.5 mm (2-pole), pin assignment under the right
side cover
Pin no. Description Function
1 Inner conductor POWER IN+ Voltage supply 14
– 30 V DC
2 Outer
conductor POWER IN- Power supply 0 V
12.3.7 Reset button under the right side cover
If it is no longer possible to operate the device for any reason (e.g. crash of the running application), the
device can be reset by activating the reset button (keep pressed for at least 4 seconds). The device can be
