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. Outer Image of Reader (Figure 1) RFID Reader (SST-US-URFR01A)

(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.

The setting of serial communication mode (DIP switch setting) DIP switch is used to set the communication mode to RS-232 or RS-485. Only one mode between RS-232 and RS-485 is used. If number 1, 2 switches are ON, RS-232 mode is activated and if number 3,4 switches are ON, RS-485 mode is activated. In addition, serial communication mode is selected though CPR-503 program as the
same mode as determined by DIP switches. (1) RS-232 mode (2) RS-485 mode (Figure 12) DIP switch setting
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 right-bottom side of the program will display "Connected" from "Not Connected". --Æ (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 CPR-503 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 (Figure 23) TAG Data Reading ⒢ Reading of TAG Data To read data in GEN2 tag, use the read item in parameter configuration tabs. Gen2 tag has 4 memory banks.

You should input memory size to be read by the word (2bytes) into an edit window next to Number of Words item. If a tag uses access password, access password should be inserted into an edit window with HEX format next to Access Password item. If a tag don't use access password, 0 is input in that window.
If all configurable parameters for reading data in a tag are set, press Read button. When reading is successful, the read data is displayed in the edit window between Access password item and Read button. ⒣ Writing TAG Data In order to write data in GEN2 tag, use Write item in parameter configuration tabs. (Refer to Figure 24). In case of GEN2 tag, data can be written in 4 memory banks. To write in each 4 memory banks, choose memory bank in BANK Selection item with a 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. (Figure 26) Locking GEN2 Tag (Figure 27) Locking Kill Password In order to lock configuration is activated, you should press Lock button. If lock is successful, the Lock success message window appears like Figure 28.

(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. Below picture shows that RF ON time was 15msec and RF Off time was 3msec and they are changed to 20msec and 10msec respectively.
(Figure 48) Setting of Time of TAG Scan period ⒟ Setting of TAG Type RFID Reader (CPR-503) supports 3types of RFID tags.
