1 General Information / Security Advice
1.1 Notes on the use of this documentation
This user manual and integration guide uses different symbols to point out potentially
dangerous situations. The following signs and symbols are used throughout the document.
ATTENTION
Declares a potentially hazardous situation. If this is not avoided, the product
or something in its surrounding could be damaged.
NOTE
Declares notes for the user as well as other useful information, where no
harmful or dangerous situations can be expected.
1.2 Security Advice
The DMI15 IoT HF RFID Reader was not designed for use in dangerous environments. Using
this product in applications where a failure could directly results in severe injuries or death
(“high risk activities”) is not permitted. This includes but is not limited to applications in
nuclear facilities, flight control systems, life support systems or weapon systems. The
manufacturer denies the suitability of this device for such scenarios.
1.3 Export Restrictions
The DMI15 contains components that underlie US Export restrictions. It is therefore
forbidden to export the product to countries that are on the US trade embargo list. The
same applies to any countries that are on the EU embargo list.
1.4 Further Documents
While this documentation explains the electrical and mechanical characteristics of the
DMI15 RFID Reader, it might be useful to also read the metraTec rotocol Guide, which
explains the ASCII protocols used to control the reader in full detail.
We also offer general information about how to set up the connection of the reader to the
antenna for optimum system performance in our HF Antenna Integration Guide.

2 roduct Description
The DMI15 is an IoT HF RFID reader/writer for demanding industrial applications, where
high reading reliability, speed and extensive special tag features are needed.
The DMI15 communicates via LAN and can be powered over Ethernet ( oE) making the
integration in IoT systems real plug and play, especially when used in conjunction with the
metraTec IoT Engine software.
Highlights include a reading rate of up to 100 tag-IDs/sec and reading and writing data on
tags without needing to address them individually. This allows applications directly at
conveyor belts, in production machinery and in electric control cabinets. The communication
protocol can be used from a normal C with a full operating system, with embedded
systems as well as with a LC.
2.1 Intended Use
RFID Reader/Writer for wireless communication with passive RFID transponders according
to ISO 15693.

3 ower Supply Electrical Specification
The preferred method of powering the DMI15 is using oE. Simply connect the DMI15 to a
oE enabled Ethernet switch using a standard Ethernet cable. The DMI15 will be detected
as a oE class 0 device by the ethernet switch. The switch will deliver up to 13W available
for the DMI15 itself shared with devices connected to the 24V outputs as well as the 24V DC
out of the DMI15. Exceeding the 13W overall power rating will result in shut down of the
power supply by the ethernet switch.
Alternatively the DMI15 can be powered using the 24V DC input which are available at the
IO connector at the front of the device (X2). If you do not use a power supply supplied by
metraTec, please make sure that your own SU provides a supply voltage of high quality.
The DMI15 uses internal diode power OR-ing at the 24V level. The oE power input is
converted to 24V and compared to the voltage at the 24V DC input. The higher voltage will
be used to supply the DMI as well as the IOs.

4 Ethernet configuration
The DMI15 offers a 100 MBit Ethernet connection as communication interface via a RJ-45
jack.
The DMI15 incorporates a metraTec TC to UART Converter (TUC) for ethernet
communication.
The default I setting is static 192.168.2.239.
The interface configuration is available at this address using a web browser (port 80).
The serial ASCII data stream is available at port 10001 using a terminal program. We
strongly recommend metraTerm available as free download on our website.
For more details and options see the metraTec TUC user guide.
