1. Overview of UHF RFID Reader
This product is RFID reader to transmit car information to a remote server for the
purpose of electronic toll collection system with RF technology. The reader reads car
information from TAG ID, which is embedded in TAG, and sends this information to the
remote server. This reader can be used for 4 channels if it is connected to 4 antennas
and can be used with parts of all antennas. The reader uses TCP/IP(Ethernet), RS-232
and RS-485 for transmitting TAG ID and receiving commands from and to the remote
server. Between RS-232 and RS-485, one interface is selected for being used as
communication interface and this is determined by dip switches in the MCU board. In
addition, the reader has RS-422 interface to communicate with other devices, such as
laser or camera, and has sync port to synchronize the operations of multi-readers.
Relay interface can be used to control the switch of an outer device. The debug port is
provided so that it can receive commands from user and display the status of reader.
LED interface shows the status of reader and antennas.
This product uses DC-24V.

(2) Connector of Antenna
(그림4) Connection of RFID Reader with Antenna
As in Figure 4 (1), Connect Rx, Tx TNC connector with Rx, Tx connector of Antenna
with antenna cable. The reader has total 4 antenna connector ports and each port has
Rx, Tx port separately. The Figure shows the first antenna is selected. Connect Rx
connector of reader's antenna port to Rx connector in an antenna and connect Tx
connector of reader's antenna port to Tx connector in an antenna. When all antennas
are not selected, it is safe to connect dummy loads to unconnected antenna ports in a
reader (Antenna selection is made in configuration menu of CPR503 program. Refer to
Figure 29). If RF signal is output through unconnected antenna port, it would give a
damage to a power amplifier in a reader.
6. Outer Interface of Reader
(1) LED Indicator
There are 6 leds in LED indicator interface. The RUN led lights as soon as power is
inserted into reader and it blinks every 0.5 second after CPU is booted. TAG led is
toggled on receiving Tag ID. (Tag led is operated only if buzzer option is selected as
ON) The remaining 4 red-leds indicate the antenna being used. For example, if the first
red-led lights, it tells that the 1st Antenna is being used.
(Figure 5) LED Indicators

8. RFID Configuration Program
RFID Reader (CPR-503) program can be used to measure the performance of a reader
or set the configuration of a reader. It commits the functions through communication
with a reader via serial/Ethernet. As major functions, this program can set parameters
used in a reader and provide interfaces for read/write/lock functions to RFID tags.
In addition, it gives the interfaces for configuration of communication environment and
displaying the information of tags which a reader recognizes.
(1) Configuration of program
Tabs for setting parameters
Window for displaying TAG information
CPR-503 program consists of 2 windows. Left windows is tabs for parameter setting,
which contains 17 items (Communication, Tag, Modulation, Scan, Anti-collision, MISC,
Read, Write, Lock, Configuration, Synchronization, Attenuation, UII write, Time, TID,
Tag indicator, Tag Test). You can select a tab using arrow button in the right corner.
Right window displays TAG information which a reader recognizes. The information
contains Serial No., the reading counter, UII, TAG ID(TID), antenna number and
reception time.
(2) Parameter Setting
⒜ Communication
Use communication item in parameter setting tabs to configure the communication
environments. The communication method can be RS-232, RS-485 or Ethernet. The
selection is committed by pressing the radio button located in left side of each
communication method. In case of RS-232 or RS-485, the port number and baud rate
should be set, too. (Refer to Figure 14)
(Figure 14) RS-232, RS-485 Connection
(Figure 15) Ethernet Connection
In Ethernet mode, the server mode or the client mode can be selected. In client mode,
IP address and port number should be set. (Refer to Figure 15) Now, the port number of
TCP is fixed to 1000. If you choose the server mode, the windows for setting IP
address and port number will be deactivated. In order to use the server mode, Server
(PC) IP address should be set in the RFID reader. (Refer to Figure 16)
(Figure 16) Ethernet (Server mode) Setting
If RS-232, RS-485 or Ethernet client mode is selected, press connect button for
communicating with a reader. In case of Ethernet server mode, it is needless to press
connect button.
When the connection is completed, the communication status indicator located in rightbottom side of the program will display "Connected" from "Not Connected".

(Figure 17) Communication status indicator
⒝ Tag type setting
RFID Reader (CPR-503) supports 3types of RFID tags. The supported types of tags are
EM-4122, ISO-6B and GEN2 among which one type should be selected using radio
button. By default, GEN2 type is selected. (Refer to Figure 18)
(Figure 18) Tag type setting
(Figure 19) Selection of modulation parameters
⒞ Selection of modulation parameters
Modulation parameters can be set in modulation tab. (Refer to Figure 19) The
modulation tab is only used when selected TAG type is GEN2. Configurable parameters
of modulation are TARI, RTCal, TRCal, Reverse link encoding method, Divide ratio (DR),
and pilot tone. TARI, RTCal, TRCal value is set by the micro second. Reverse link
encoding method can be FM0, Miller2, Miller3, Miller8, but now the CPR-503 reader
supports only Miller2 encoding.
Divide ratio cab be set with 8 or 64/3. Pilot tone
determines which preamble is used, short preamble or long preamble. By default, TARI
is set to 12micro seconds, RTCal is set to 33mirco seconds, TRCal is set to 66micro
seconds, Reverse link encoding is set to Miller 2, Divide ratio is set to 64/3 and Pilot
tone is set to long preamble.
[CAUTION] Except of a special case, do not change default modulation parameters.
⒟ Setting of duty cycles of RF power
In order to set the duty cycles of RF power of a reader, the scan item can be used.
RFID uses RF power which is turned on/off periodically. The period of ON/OFF state of
RF power can be set with milli-second. However, if, in the RF ON period, a tag is
already read or it is determined that no more tag can be read (As such a case, It will be
possible that although query message and query-repeat message in all slots allocated
for anti-collision are sent, tag id cannot be received), RF ON period will be switched to
RF Off period. Therefore, RF ON period is flexible within the period user sets, but RF
OFF period is fixed as same as the period user sets.
(Figure 20) Setting of RF power duty cyle (Figure 21) anti-collision setting
⒠ Anti-collision setting
When GEN2 protocol is used, anti-collision function is permitted using Q value in Query
message which can be set in the Anti-collision item in parameter setting tabs of CPR503 program. (Refer to Figure 21)
Using the Q value, GEN2 tag generates random number for choosing slot in which it
sends its TAG ID. After RFID reader transmits Query message, it sends (2Q-1) Query
Repeat messages. If TAG receives the message, it decreases its slot number by 1 and if
the slot number reaches to 0, the TAG responds to the message by transmitting it TAG
ID. Q value can be set from 0 to 15. Value of 0 means that anti-collision function is
disabled.
⒡ Buzzer Setting
In order to make the buzzer ring when a reader receives a TAG ID, you can set Buzzer
item in MISC tab of parameter configuration tabs. (Refer to Figure 22)
If you want to ring the buzzer on receiving the tag id, you can select ON in combo
button, and if you want the buzzer to remain silently, you can select OFF in combo
button.
(Figure 22) Buzzer Setting

radio button and input the starting address to write in the edit window next to Starting
address item. The data to be written is inserted into edit box next to Data item. Access
password is inserted in an edit window next to Access Password item with HEX format.
If a tag don't use access password, 0 should be written in that window. If all
configurable data are input, press Write button. If the writing is successful, Write
success message will appear (Refer to Figure 25)
(Figure 24) Writing Tag Data
(Figure 25) Success of the writing data in a tag
⒤ Tag Lock Setting
With GEN2 tag, 4 banks can be selected for locking using Lock item in parameter
configuration tabs. (Refer to Figure 26)
Reserved memory bank can be locked in kill password memory or access password
memory. Lock status is determined with pwd-read/write item and permalock item as
follows
Above status is the case when Password Read/Write and Permalock is checked by
skip/write item. That is, if skip/write is checked, the lock item left to the skip/write
button is applied and if not checked, the lock status left to the skip/write item is
maintained as it was.
In case of Figure 27, it shows that Kill password is locked permanently.

- Flow control : None
(Figure 43) Configuration of communication parameters
⒝ Connect RS-232 cable between PC and DEBUG port in RFID reader.
⒞ If connection is finished, press ENTER key and be sure that /home/frog# prompt
appears as below Figure 44 (When reader is booting, the booting message will appear
and it also means connection is completed)
(Fiure 44) Connection of serial communication
(2) Menu
if /home/frog # prompt appears, press ./menu and press enter key. The menu like below
Figure will be displayed.
(Refer to Figure 45)
(Figure 45) menu
⒜ Setting of modulation parameters
To set modulation parameters of GEN2, press 1 and press enter key in menu.
Configurable parameters of modulation are TARI, RTCal, TRCal, Reverse link encoding
method, Divide ratio (DR), and pilot tone. TARI, RTCal, TRCal value is set by the micro
second. Reverse link encoding method can be FM0, Miller2, Miller3, Miller8, but now
the CPR-503 reader supports only Miller2 encoding. Divide ratio cab be set with 8 or
64/3. Pilot tone determines which preamble is used, short preamble or long preamble.
By default, TARI is set to 12micro seconds, RTCal is set to 33mirco seconds, TRCal is
set to 66micro seconds, Reverse link encoding is set to Miller 2, Divide ratio is set to
64/3 and Pilot tone is set to long preamble.
The numbers in () of each item means current values.
[CAUTION] Except of a special case, do not change default modulation parameters.
(Figure 46) Setting of modulation parameters
Select TARI, RTCal, TRCal, Reverse Link Encoding, Divide Ratio and Pilot Tone and
select y for confirmation question.
⒝ Anti-collision
When GEN2 protocol is used, anti-collision function is permitted using Q value in Query
message which can be set in 2nd menu item. (Refer to Figure 47)
Using the Q value, GEN2 tag generates random number for choosing slot in which it
sends its TAG ID. After RFID reader transmits Query message, it sends (2Q-1) Query
Repeat messages. If TAG receives the message, it decreases its slot number by 1 and if
the slot number reaches to 0, the TAG responds to the message by transmitting it TAG
ID. Q value can be set from 0 to 15. Value of 0 means that anti-collision function is
disabled. The below picture shows the Q value is set to 3.
(Figure 47) Anti-collision setting
⒞ Timer Setting
In order to set the duty cycles of RF power of a reader, select 3 item in menu.
RFID uses RF power which is turned on/off periodically. The period of ON/OFF state of
RF power can be set with milli-seconds. However, if, in the RF ON period, a tag is
already read or it is determined that no more tag can be read (As such a case, It will be
possible that although query message and query-repeat message in all slots allocated
for anti-collision are sent, tag id cannot be received), RF ON period will be switched to
RF Off period. Therefore, RF ON period is flexible within the period user sets, but RF
OFF period is fixed as same as the period user sets.

⒫ Buzzer setting
To determine whether Buzzer rings when TAG ID is received or not, use 16th item in
menu. If 0 is set to Buzzer mode, Buzzer mode will be OFF and Buzzer will not ring
when TAG ID is received. If 1 is set to Buzzer mode, Buzzer mode will be ON and
Buzzer will ring when TAG ID is received.
(Figure 58) Setting of Buzzer mode
⒬ RF Tx Control
To determine whether to always maintain RF power ON or always maintain RF power
OFF or set ON/OFF time period, use 17th item in menu.
If 0 is set, timing mode is enabled and a reader turns on RF power during ON time
period and turns off RF power during OFF time period. The ON/OFF timing is set in 3rd
