1 Introduction
1.1 XT-2 Reader
The XT-2 RFID reader is a full functionality EPC Gen 2 (ISO 18000-6C) reader for
access installations such as Parking, Gated Communities and Condominiums. The
reader is available in two models: XT-2 eu for the European market (865.6-867.6 MHz)
and XT-2 us for the US market (902-928 MHz). The reader has a built-in antenna and
can be expanded with an optional external antenna. The read range is five meters for
XT-2 eu and six meters for XT-2 us.
XT-2 supports the TagMaster SecureMarkIDTM acquisition system developed to ensure
that each tag has a truly unique identity impossible to duplicate. The XT-2 Reader can
be equipped with all TagMaster reader application software providing suitable
functionality. Customer specific applications can be developed using TagMaster’s
Software Development Kit (SDK).
The reader can be configured and controlled via the Ethernet interface, either locally or
remotely via an Internet connection. The XT-2 Reader supports several standard
interfaces including Ethernet (TCP/IP), RS232, RS485 and Wiegand/Mag-stripe.
More detailed information about the reader’s functionality is available in 06-118, “GEN4
Reader User’s Manual”.
1.2 TagMaster’s RFID System
TagMaster’s RFID system consists of readers and ID-tags. Readers can work
standalone or be connected to a host computer using serial or Ethernet interfaces.
1.2.1 Reader
The reader is a device for reading ID-tags using radio frequency. Some readers have
the capability to write information to ID-tags that support this.
The reader has a built-in antenna for communication with ID-tags. Some readers can
be expanded with external antennas. The reader also has various interfaces for
communication with a host computer and other external devices. When an acceptable
ID-tag is read, the reader can for example pull a relay connected to a barrier and grant
access to a vehicle and at the same time sound the buzzer and flash the visible
indicator.
To reduce the risk of interference, several readers in close proximity to each other
should use frequency hopping or be set to different frequency channels.
1.2.2 ID-tags
An ID-tag carries information that can be read at a long distance using radio frequency.
TagMaster has a range of ID-tags with different properties. Technical data for the
different ID-tags are presented in the respective ID-tag’s data sheet.

3 Installation
This section describes the procedure of installing the reader, that is mounting the
reader and installing the necessary cables. Read through this entire section before
performing the installation.
Caution!
Install the reader in accordance with local and national building and electrical codes
and/or applicable jurisdictions i.e. state or federal laws or city ordinances. The reader
is designed for installation using Class 2 wiring. Installation shall be performed by a
qualified service technician.
3.1 Environmental Considerations
The XT-2 reader is a reliable solution for identification systems because it is unaffected
by the normal electromagnetic background noise found in industries and elsewhere.
3.1.1 Electromagnetic Interference
Industrial noise is typically present in the kHz and low MHz frequency band. The XT-2
reader uses 860-960 MHz frequencies, so typical industrial noise will not affect the
communication.
3.1.2 Electromagnetic Interference in Cables
By using specified cables, proper shielding, and grounding as well as selecting a
suitable communication interface, optimum communication reliability is ensured. For
more information about cable specifications see section 3.2.2, “Cables and Power
Supply”.
3.1.3 Lightning
In order to protect the reader from possible effects of lightning, additional surge
protection on the inputs and outputs may be needed.
3.1.4 Temperature
For most applications, normal convection cooling is sufficient for the reader. But if heat
is generated close to the reader, the use of forced cooling or heat shields should be
considered.
3.2 Preconditions
The locations of readers and ID-tags have been specified during the project planning
phase, based on considerations of communication distances and movement speeds.
The cable paths and cable types have been determined during the project planning
phase.
The power supply must comply with all relevant safety regulations.

XT-2 Reader Installation Manual & Data Sheet Doc no. 10-407 02
© TagMaster 7 (26)
The equipment must be disconnected from all voltage sources before any installation
or service work is carried out. Capacitors inside the equipment can hold their charge
even if the equipment has been disconnected from all voltage sources.
Caution!
Damage may be the result if the equipment is switched on when parts are removed
from the controller board, or if a PCB is removed within one minute after switching off
the equipment.
3.2.1 Tools
The following tools are necessary for installation:
•Socket wrench
•Hexagon socket 7 (for M4 casing nuts and XT-2 mounting kit)
•Adjustable spanner
•Screwdriver, Philips PH00x60 or SZS 0,4x2,5
•Side cutter
•Wire stripper
•Crimping tool for ferrules
3.2.2 Cables and Power Supply
Cables and power supply are not supplied with the XT-2 reader.
All cables should be shielded and suitable for the installation environment, for instance
indoor or outdoor environment. Use flexible cables with stranded wire.
The terminal blocks used are Phoenix, type PT 1.5, which allow for a cable area of 0.2
to 1.5 mm² (AWG 26-14). Stranded wires must be fitted with a ferrule before being
inserted in the termination blocks.
The cable for the RS485 interface must be a twisted pair cable and conform to the EIA
RS485 standard.
A category 5 (CAT5e) cable is required for the Ethernet connection.
The reader shall be powered by a UL Listed or Certified, Class 2 or LPS power supply
suitable for outdoor use, rated 24 V DC, 1 A minimum. The power supply shall fulfil the
specifications in section 5.4.2, “Power supply, J31”.

3.3 Mounting the Reader
Mount the reader in a horizontal position with the cable glands on the bottom side.
Direct the reader so that the reading lobe covers the positions of the ID-tags.
For optimal performance, tilt and rotate the reader into a position so that the front side
of the reader is parallel with the front side of the ID-tag to be read. Align the reader so
that the actual reading range is 60–70% of the specified maximum.
The figure below shows a typical reader installation. Note that the installation details
depend on site requirements.

100%
60 - 70%
Figure 2 Reading lobe
How to mount the ID-tag depends on the type of tag and which object that is being
tagged. TagMaster’s windshield ID-tag should be mounted in a horizontal position in
the windshield. Note that some cars have a metallized windshield. The ID-tag must be
mounted in an area of the windshield without metallization.
Warning!
To comply with Council Recommendation 1999/519/EC, it is recommended that the
reader is installed so that a separation distance of at least 20 cm (8 in) from all persons
is provided.
The XT-2 Mounting Kit (Part No. 194900) from TagMaster enables the reader to be
mounted in a wide variety of positions and angles. The kit contains all parts needed for
mounting the reader on a wall or on a pole. The XT-2 Mounting Kit is suitable for both
indoor and outdoor use.

4 Testing
4.1 Installation Test
After having completed the installation as described in previous section, carry out an
installation inspection and verification. If an error occurs, the guidelines in section 4.2,
“Trouble Shooting”, may be valuable.
4.1.1 Inspection
Ensure that there are no metal objects between or close to the reader and the ID-tag in
the positions where communication is to take place.
Ensure that the reader and the ID-tag are aligned properly. Avoid communication at
maximum specified distance and misalignment.
Ensure that the reader is not placed in a location where it is exposed to excessive heat
or electromagnetic interference.
4.1.2 Verification
Power up the reader and verify that it beeps once.
If the hardware fails to initiate, the reader will make two more attempts to initiate it.
Each attempt is indicated by a short beep. If the hardware does not initiate after three
attempts the reader will not read tags. See section 4.2, “Trouble Shooting” for more
information.
Verify that the reader reads ID-tags and that the read lobe covers the required area. If
specific reader application software is used, consult the corresponding software
manual for more information concerning installation test.

5.2.14 Interface Isolation and Protection
The hardware design is protected against radiated or wired disturbances by extensive
use of filters, transformers and shielding. The power input is galvanically separated
from the main electronic part of the reader by use of an on-board DC-DC converter.
The Interface Block with Ethernet, Serial Interfaces and I/O signals is also galvanically
isolated from the rest of the reader. This makes sure that no ground currents will occur
between shielding, power lines or other interfaces. The common GND connection in J2
and J41-J43 is a floating reference ground for the interface block signals. This makes it
possible to operate the interface with the voltage potential set from the other party. The
reference ground is internally connected to the chassis via a discharge resistor to avoid
static voltage potential. It has no other reference to connections outside the interface
block.
The USB port GND is connected to the chassis.
The Wiegand/Mag-stripe interface, the Isolated Inputs, and Isolated Outputs have a
varistor protection that will short-circuit signals over rated maximum 30 V.
