ib technology Data Sheet UNI_RS232_USB.pdf 9 Pages Last Revised 03/09/09 Universal RFID Socket board with RS232 / USB interface The Universal RFID Socket board is the baseboard for the MicroRWD RFID reader modules from IB Technology. 82 mm 75 mm MicroRWD modules are low-cost, pin compatible and host command compatible Proximity reader modules for Hitag 1, Hitag S256/2048, Hitag 2, Mifare 1k/4k/Ultralight, ICODE SLI and EM400X/4102 RFID tags and contactless smart cards. The module solutions only require a 5v supply and an antenna coil to be fully featured read/write systems with optimised easy to use host commands. All modules use the same universal 24 pin DIP package so customers can migrate between different transponder technology with the minimum of design change. Mifare Hitag 2 Quad Tag ICODE Hitag 1/S EM Marin The Universal Socket board provides the antenna, power supply regulation and RS232 / USB interfaces to the MicroRWD module itself. Specifically the board has a 24 pin DIP socket for the appropriate MicroRWD module to be plugged into, LEDS for visual status indication, selectable PCB and coil based antenna for 13.56MHz and 125kHz operation and voltage regulation allowing 9-12v DC power supplies to be used. The Universal Socket board with the appropriate MicroRWD module fitted is a complete “ready-to-use” RFID reader system and is used in the SDK/Evaluation kit together with sample tags/cards and CDROM containing all the data sheets and Windows applications (executable and C source). 1 ib technology Universal socket board (with 125kHz coil antenna mounted on the underside) was designed to fit in the Evatron EVA73 plastic case giving the option of a fully enclosed product. The Universal socket board can be powered directly from a stabilised 5 volt supply, from the 9-12 volt DC connector or from the USB bus. The MicroRWD module itself has a low average current (approximately 15-20ma) but consumes up to 200ma in a short burst every polling cycle when the RF is turned on for the brief communication period. The Universal socket board uses a 470uF capacitor across the supply rails to smooth these current pulses and so the entire board consumes around 60 ma and can operate directly from a USB bus with no external power supply. Universal socket board link options The board has link options to select the on-board 13.56MHz PCB antenna or the external 125kHz antenna coil and various options for supplying power to the board and interfaces.

The interface and communication pins can also be accessed directly from CON J9. For this case the links J2, J4, J5, J7 can be removed to ensure that only the MicroRWD module is powered and the MAX202 and the USB module (if fitted) are OFF. Operation of MicroRWD module using RS232 interface The MicroRWD module can be powered from an external 5 volt stabilised or 9-12 volt unregulated supply (Link J2 set accordingly). For RS232 communication, link J7 should be closed to power the MAX202 device. A standard RS232 extension cable (straight-through, pin-to-pin) is used to connect CON J10 to a PC COM port or other host RS232 interface. Operation of MicroRWD module using USB interface (if fitted) The MicroRWD module can be connected to and powered from an external USB bus. To ensure the board consumes minimum power, links J2 and J7 should be removed to disconnect the MAX202 power and regulator supply. Links J4 and J5 should then be closed to connect the external USB bus 5 volt supply to the USB module and the MicroRWD itself. The Universal RFID socket board uses the low-cost FTDI (Future Technology Devices International Ltd) MM232R “serial to USB converter” module. If not already fitted, the module can be purchased on-line from http://www.ftdichip.com/ FTDI USB – serial interface module MM232R The USB module should be connected to the PC USB port using a standard USB connecting cable. All the Windows applications for the MicroRWD module currently communicate with the serial COM ports and assume RS232 connection. FTDI provide a VCP (Virtual COM Port) driver for the MM232R module that allows standard RS232 communication programs to operate over the USB bus. The VCP drivers for various Operating Systems can be downloaded from http://www.ftdichip.com/Drivers/VCP.htm and installed according to the supplied instructions (VCP driver file: CDM 2.00.00 or later). With the Universal RFID board connected to the USB bus, the Windows applications can be run in the usual manner with a COM port selected higher than the maximum COM port number on the PC being used. 4 ib technology FTDI MM232R USB Module pin out and PCB pad layout +5v Link J4 2-way pin header FTDI MM232R USB/RS232 module, MOD1 C7 Rx Connected to MicroRWD CTS, Tx and Rx pins Tx CTS USB SLEEP USB CLK12 USB PWREN USB RESET 0v GND Link J5 2-way pin header For USB powered RFID board, short linksJ4 and J5 For external 5v supply, short link J4, open link J5 5 ib technology RS232 interface circuit and connector pin out (DCD, DTR, DSR joined) MicroRWD CTS (BUSY) connected to CTS +5v 1, 4, 6 - joined 2 – Tx 3 – Rx 5 – GND 8 - CTS CON J7 2-way pin header CTS Tx 1 Rx 6 C15 Connected to MicroRWD CTS, Tx and Rx pins C14 + C3 C17 C16 C18 1 16 2 15 MAX20214 3 U2 4 13 5 Rx 12 CTS 11 Tx 10 6 7 8 9 0v Ground Plane 6 9 5 CON J10, 9 way D-Type socket RS232 connector ib technology MicroRWD module interface circuit and pin out RWD +5v D2 R1, R3 1k Red LED 24 1 CTS Tx D1, Green LED MCLR/Vpp Rx RWD +5v SW1 Micro RWD (MOD2) OP3 R2, R8 OP2 0v GND RWD +5v AN3 AN1 AN5 AN4 OP0 R4, R9 OP1 CON J9, 2 x 10 x 0.1 inch pin header AN1 Red LED Grn LED OP3 OP2 USB SLEEP USB CLK USB PWREN USB RESET 0v GND 5v AN2 AN2 12 AN6 13 CON J8 For 125kHz antenna link AN1-AN5, AN2-AN6 For 13.56MHz ant’ link AN1-AN3, AN2, AN4 0v GND C12 = 22pF 1 uH PCB antenna (L2) C19, 5-50pF trimming capacitor 1 AN3 R6, 0R C10 = 180pF C11 = 220pF AN4 R7, 0R R5 C13 = 22pF C8, C9 AN5 ANT1, L3 700uH Antenna 27R 47pF AN6 47pF Through hole solder pads for wire coil connection.
