Chapter 1: Introduction
The XCRF-500 reader series are electronic tag readers
developed by Shenzhen Yuanwanggu Information Technology
Co., Ltd. These readers are applicable to reading/writing
XCTF-5000 tag series that satisfies NCITS256-1999 protocol
and works within UHF frequency range, as well as compatibly
reading AMTECH’s UHF tag used in vehicle identification.
With its compatible electronic tags, XCRF-500 reader series
could be widely deployed in the areas like custom vehicle
automatic identification, urban vehicle automatic identification
management, highway non-stop toll, etc.
XCRF-600 reader can only read the tags that meet the proposal
of EM4223. XCRF-600 reader needs only to send RF power
to tags, one tag will send its ID information. XCRF-600 reader
can be widely deployed in the doorway management, etc.
XCRF-500 reader series includes 4 reader models:
XCRF-500W, XCRF-501W, XCRF-502W and XCRF-504W.
XCRF-500W is single-ported reader where only antenna 1 can
be connected with external antenna. XCRF-501W is
antenna-built-in reader, XCRF-502W is dual-ported reader,
2
both antenna 1 and antenna 2 of which can be connected with
external antenna. XCRF-504W is four-ported reader, antenna 1,
antenna 2, antenna 3 and antenna 4 of which can be connected
with external antenna. In the case that the reader you ordered is
multi-ported, it is necessary to connect the unused antenna
ports to 50Ω/20W dummy load in order to protect the reader.

1.1 System Advantage
From the point of data collection, radio frequency
identification system completely resembles bar code system. In
the course of data collection, bar code system adopts one-way
communication, i.e., bar code sensor (reader) reads information
from bar code in non-touch way. During such information
flowing, bar code is totally in a passive and subordinate
position and the communication is one-way, i.e., information is
transmitted to bar code sensor from bar code tag.
The shortcoming of bar code system is that, if damaged,
polluted, damped or located inside an article, the bar code
couldn’t acquire data because the reading range of sensor is too
short.
Data collection system composed of XCRF-500 reader series
and their compatible electronic tags, fundamentally overcomes
the above shortcoming of bar code system. The communication
between reader and tag is two-way, in which the tag makes
4
relevant response to reader’s demand. With two-way
communication, system could realize the function of reading
multiple tags within reading area.
Matched with appropriate antenna, the reading range of
XCRF-500 reader series could be over 7 meters.
1.2 System Capability Characteristics
ø Ability to read part of or all the data information of a
single tag;
ø Ability to read part of or all the data information of
multiple tags under the circumstance of no unpacking
and ordering;
ø Ability to screen specific electronic tag according to
the user-defined rules;
The super inquiry protocol followed by reader and electronic
tag enables reader to unerringly identify every electronic tag
within reading area and read each tag only once.
The unique protocol between reader and electronic tag decides
that when multiple tags are read, every tag spends the same
reading time, independent of tag quantity within reading area
(regarding XCTF-5000 electronic tag).
5
1.3 XCRF-500 reader series
XCRF-500 reader series are designed for reading and writing
UHF tag of XCTF-5000, while keeping compatible with
AMTECH vehicle tag.
XCRF-500 reader series provides 1 to 4 radio frequency
interfaces for external radio frequency antennas. Radio
frequency cable should employ low loss cable, and the length
of radio frequency cable equipped with reader is 10 meters.
Lengthening the radio frequency cable or using general radio
frequency cable will affect the reading/writing range of reader.
Note:
(1) Joint between radio frequency cable and reader is N-type
joint, connection of which should be tight and reliable.
Over-tight joint connection would damage the joint socket,
while a loose one would cause system performance decline
(reading/writing distance).
(2)Switching on the power and transmitting microwave prior to
disconnecting antenna might cause serious damage to the
system.
(3) Unused antenna port should be connected to 50Ω/20W
load.
6
1.4 Other Required Accessories
Besides reader and tag, IBM-compatible personal computer
system and interface software for reader are also needed to
build a integrated radio frequency identification system and
data collection system.
The minimum requirement for personal computer system is:
ø 9-firing pin RS-232 serial port;
ø Well adaptive to Windows 98/2000/XP;
Interface software for reader includes:
ø API Dynamic-Link Library for XCRF-500W reader
series;
ø API and demo software V1.1 for XCRF-500W reader
series;

2.5 Connect external antenna
There are 2 N-type coaxial cable joints (Female) on the back
panels of XCRF-500 reader series to connect the external
antenna. Be sure that the installation of the antenna must be
performed by professional installers authorized by the
provider. Sketch map of connection between reader and
external antenna is shown in figure 2-4.
Low loss radio frequency cable with a standard length of 10
meters is recommended for the connection between reader and
antenna. Insert loss of the Low loss radio frequency cable
must be at least 1 dB and less than 2dB.When connecting
with antenna and reader, the cable joint should be tightly
screwed. In practical installation, a heat-contracted pipe should
be used to airproof the cable joint for protection once it is
screwed.

(Sketch map)
2.6 Install external antenna
External antennas of XCRF-500 reader series are usually
installed outdoors. The area that its wave beam covers is the
valid area for system reading/writing electronic tag.
Depending on the specific requirement on the application spot,
external antenna of reader could be either
horizontal-top-mounted or vertical-side-mounted . The angle
of inclination or rotation of antenna could be adjusted to enable
Antenna XCAF-11
15
the best reading/writing performance.
Usually XCRF-500 reader series should be used with linear-
polarized antenna (to avoid antenna loss). In a on-spot
installation, do pay attention to the polarization matching
between reader antenna and tag antenna, otherwise the
reading/writing range might be seriously affected.
2.7 Connect to PC serial port
XCRF-500 reader series provides RS232 serial interface. The
9th foot of the serial interface provides an output power of +5V
DC, which meets standard RS232 transmission, easily connects
to expanded USB interface module, connects to standard radio
communication module of WLAN802.11b protocol to meet the
requirement of radio data transmission within 10m, or connects
special radio communication module to meet the requirement
of radio data transmission within 200m.
In addition, XCRF-500 series readers also provide a 10M
network interface to meet the requirement of high-speed data
transmission.
2.8 Connect to external AC power supply
Follow the below steps to connect to AC power supply of
16
XCRF-500 reader:
(1) Make sure that the voltage is AC100V ~ 240V and working
frequency is 50Hz;
(2) Make sure that the switch of XCRF-500 reader series is off;
(3) Plug one end of the power line into the socket of AC power
supply, and another end into the triple-cored-cassette AC
power input of XCRF-500 reader series
(4) Turn on the switch on the front panel of XCRF-500 reader
series. After a beep, power supply indicator lights up, then
the reader is initialising, and the system is standby after
finishing initialising process.
Note:
When XCRF-500 reader is in default status, the system is in
standby status after start-up. The reader does not transmit radio
wave when it is initialising or standby (radio power amplifier is
off). Only after connected to antenna or load and receiving
‘Read/Write tag’ command from PC or ‘Enable Power
Amplifier’ command, Power Amplifier of reader turns to
working status.
Caution: It is harmful for readers to enable the Power
Amplifier with the absence of the connection to antenna or
17
dummy load.

Chapter 3: RF Communication
Generally, the system performance of the devices employing
radio communication technology is very sensitive to signal
interference and attenuation. This chapter addresses the
optimisation issue of radio frequency communication between
XCRF-500 reader series and electronic tag, which includes:
（1） Signal interference
（2） Signal attenuation
（3） Optimisation of system performance
3.1 Signal interference
Signal interference is the radio frequency (RF) signal caused
by the information exchange between reader and electronic tag.
Signal interference might seriously impair reader’s ability to
read the data of electronic tag. The flashing of receiver
indicator indicates the existance of interference signal, and the
flashing frequency represents the extent of signal interference.
The sources of interference signal include:
ø Radio frequency (RF) system, e.g., RF local-area
network, nearby interactive identification system;
ø RF signal radiated from security gate, garage door or
22
other devices;
ø Radiation source of other radio frequency (RF);
The influence of these interference sources can be eliminated or
reduced by adjusting the installation position and direction of
the reader and antenna.
When radio frequency (RF) interference or noise exists, the
performance of reader system (exchange data with electronic
tag) will dramatically decline. The reader can only “receive”
one signal at any time, not able to differentiate the unexpected
“noise” and expected “useful RF signal”.
23
3.2 Signal attenuation/reflection
Signal attenuation refers to the natural attenuation of signal
strength with the distance increasing. Meeting blocks during
signal transmission might also cause attenuation.
The blocks probably affecting the transmission of radio
frequency signal include:
ø Close-ended space comprised of concrete wall, floor
and ceiling;
ø Metal surface surrounding antenna or tag;
ø Water or other liquids surrounding antenna or tag;
Almost every object (furniture or blocks) in the path of
transmitting radio frequency signal will cause attenuation to
different extent. With an elaborate adjustment to the installation
position, the attenuation of radio frequency caused by blocks
can be lessened to possible least.
The reflection from the metal or metalized surface back close
to the electronic tag can affect the signal attenuation. In some
situation, this could be solved by slightly increasing reading
distance, but at the same time some ‘dead corners’ will appear
24
within reading area. When the electronic tag is positioned in
dead corners, the communication between reader and tag will
be very poor.
25
3.3 Optimisation of system performance
Generally, it is impossible to precisely predict the system
performance of the reader under any given circumstance (the
root is the complexity of electromagnetic radiation, including
the frequency stability of signal source, the direction of antenna,
antenna side-lobes and the environment). However, the
suggestions below are instructive to optimising the system
performance in practice.
ø Elaborately design and install the antenna of reader.
The standard length of radio frequency cable between
antenna and reader is 10 meters. Over-lengthy radio
frequency cable will bring about attenuation of both
transmitted signal and received echo signal, which will
shorten the reading range.
ø Change in antenna connection or antenna type will
significantly affect the system performance.
ø Take the surrounding into consideration:
construction materials, office hours, windows and pipe
configuration, etc. Radio frequency field mode and
26
ø reading range could be affected by the nearby metal
articles like the household appliance, equipments,
metal frames, etc.
ø Make sure that the objects attached with the electronic
tags to be identified stay within the valid reading area
for longer than 10 milli-second (regarding XCTF-5000
electronic tag).
ø The polarization direction of the reader antenna shall
be the same as that of the electronic tag antenna. If the
reader antenna is linearly polarized, the electronic tag
could be rotated by 90 degree to find out minimum
and maximum reading range.
ø If the reader antenna is round polarized, the electronic
tag may be rotated by 360 degrees in the plane facing
the reader antenna without affecting the reading range.
ø In the case that the electronic tag is vertical to the
reader antenna, the reader-writer antenna can’t
communicate with the electronic tag, however it is
polarized.
ø The optimal length of electronic tag antenna is related
to the non-conduct material in which the antenna is
packed or embedded. The basic idea is: for the
ø electronic tag packed in non-conductor (its dielectric
27
constant is usually larger than that of the air, and thus
its effective wave length is shorter than that in the air),
if its effective electrical length is adjusted to the
optimal length in the air (the corresponding reading
distance to the reader-writer is the longest), and when
the antenna is packed in the non-conduct material, the
electrical length of the antenna should be shortened to
parallel the optimal effect in the air. On the contrary, if
the electrical length of the antenna is adjusted to the
optimal, then its optimal electric length in air should
be increased.
ø To avoid the mutual interference between multiple
electronic tags installed on one object, any two
electronic tags should keep enough distance to each
other. The interference between multiple electronic
tags will occur when the distance between two
electronic tags is less than 10cm and their distances to
the antenna are equal.
ø Keep the bare or unpacked electronic tags away from
chemicals. Some chemicals, such as alcohol, will not
affect electronic tags in the normal temperature, but
will somewhat cause corrosion when the temperature
gets higher,
