Page 10: Ethernet Configuration
4 Ethernet configuration The DMI15 offers a 100 MBit Ethernet connection as communication interface via a RJ-45 jack. The DMI15 incorporates a metraTec TCP to UART Converter (TUC) for ethernet communication. The default IP setting is static 192.168.2.239. The interface configuration is available at this address using a web browser (port 80). -
Page 11: Rfid Antenna
5 RFID Antenna To send and receive data to and from passive RFID tags the DMI15 includes a HF RFID antenna (13.56 MHz, 50 Ohm) The antenna is located centered at the front of the housing. The antenna center is indicated by the top print. -
Page 12: Digital Input/Outputs
6 Digital Input/Outputs The DMI15 has 2 digital inputs and 4 digital outputs which can be read or set via the reader. The input pins are optically isolated 24 V DC inputs as is common in automation technology. Up to 10 mA are needed to set the input to "high". - Page 13 These can be used as power supply outputs to supply e.g. sensors, etc. The power of these pins is limited by the power of the power supply used or the PoE power limit.
