4.3 Operating principle
The readers are used for contactless data exchange with tags. For this the controller sends com-
mands and data via the interface to the reader and receives the corresponding response data
from the reader. The reading of the IDs of all RFID tags in the read area or the writing of an RFID
tag with a specific production date are examples of typical commands. To communicate with
the tag, the data of the reader is coded and transferred via an electromagnetic field, which at
the same time supplies the tags with power.
A reader contains a transmitter and a receiver, an interface to the interface module and a coup-
ling element (coil and dipole antenna) for communicating with the tag. Electromagnetic wave
propagation is used for the transmission between reader and tag on devices for the UHF range.
IC Tag
UHF: electromagnetic wave
Reader
Fig.3: Operating principle of UHF-RFID
The antenna of the reader generates electromagnetic waves. This produces a transmission win-
dow as a so-called air interface in which the data exchange with the tag takes place. The size of
the transmission window depends on the combination of readers and tags, as well as on the
relevant environmental conditions.
Each reader can communicate with a number of tags. This requires the reader and the tag to
operate in the same frequency range. Depending on the power and frequency used, the device
ranges vary from a few millimeters up to several meters. The specified maximum read/write dis-
tances only represent typical values under laboratory conditions without allowing for the effect
of materials. The achievable distances may vary due to component tolerances, the mounting
situation in the application, ambient conditions and the effect of materials (particularly metal
and liquids).

V02.00 | 2021/05 11
4.4 Functions and operating modes
The devices operate with an integrated or external antenna (TN-UHF-Q300…) or only with an
external antenna (TN-UHF-Q180L300…). The devices enable passive UHF tags to be read or
written in single and multitag operation. For this the devices form a transmission zone that
varies in size and range according to the tags used and the operating conditions of the applica-
tion. Refer to the data sheets for the applicable maximum read/write distances. The devices can
be fully tested, configured and parameterized from a PC using the specified software tools.
The Linux operating system enables the device functions to be programmed with C, C++,
NodeJS or Python. It is also possible to integrate middleware functions on the device.
Sensors and actuators can be connected to the configurable digital channels. Up to four 3-wire
PNP sensors or two PNP DC actuators with a maximum output current of 2 A per output can be
connected. An external power supply is required in order to use the digital channels as outputs.
4.5 Technical accessories
Accessories for mounting, connecting and parameterizing can be found in product database
under www.turck.com. The accessories are not part of the scope of delivery.

7 Commissioning
The Linux operating system enables the device functions to be programmed with C, C++,
NodeJS or Python.
Additional software tools (e.g. PuTTY) are required to access the device via the console. A file
exchange between the device and a PC can be used, e.g. via WinSCP. The following login data
is stored on the device by default:
User: user
Password: password
NOTE
The reader log is not implemented by default. The protocol must be implemented
by the user.
7.1 Parameterizing readers with the DTM
The UHF settings of the device can be assigned additional parameters via the DTM.
All the required Turck software components can be downloaded via the Turck Software
Manager. The Turck Software Manager is available free of charge from www.turck.com.
NOTE
The parameterization function up to firmware version V2.0.39.3937 is only available
in English. All parameters are written in the DTM.
The individual readers are available in different variants. When a connection is made to a con-
nected reader, the DTM automatically detects the relevant device and deactivates menu items
that are not supported. The connection cannot be established if a different variant than set in
the project tree is connected.
NOTE
Adjustable parameters are indicated in the DTM with green arrows. Fixed paramet-
ers are indicated with gray arrows.
