Commissioning↑
The DI Extension is installed on a DIN rail in a suitable enclosure.
Connect the power supply and Link communication to the Miniserver.
You can connect push buttons to the digital inputs, for example. When using the inputs as frequency counters, wind sensors or S0 meters can also be connected.
If the devices are connected to different power supplies, it is essential that the GNDs are interconnected.
The Extension starts after switching on the power supply, and the status LED will flash orange after a short time when the connection to the Miniserver is established.
Then follow the pairing procedure on the Link Interface.

| Serial number | Specifies the serial number of the device. For Extensions: Enter 'Auto' to automatically pair an extension with unknown serial number. This can only be used if there is only one Extension of the same type. Save into the Miniserver, in order to pair the Extension. Afterwards the program must be loaded from the Miniserver to transfer the actual serial number of the Extension into the program. |
