Appendix A. “Schematics and Layouts” – the schematic and layout diagrams of the board. Appendix B. “Bill of Materials (BOM)” – lists the parts used to build the board. ECCEL Technology provides online support via our website at www.eccel.co.uk and e-mail sales@eccel.co.uk. -
Page 3: Introduction
The RWD SMT Baseboard allows the user to communicate through a USB interface to a PC. The board can be connected to the USB port of a PC with a FTDI VCP (Virtual Com Port) driver installed, allowing the Windows applications to communicate with the reader module via the allocated COM port. -

1.3 Product overview Note: Mounting hole spacing: 109 x 75 mm. Hole size is 3.2 mm. -
Page 5: Outputs And Headers
1.4 Outputs and headers The RWD SMT baseboard has link options to allow selection between the on-board 125 kHz PCB antenna or the external 125 kHz antenna coil. The P1 UART connector allows the user a simple connection to an embedded system for evaluation and prototyping. -

Page 7: Installation And Operation
(see section 1.4). To start using the RWD SMT baseboard, simply connect it to a PC via the micro-USB cable. When power (5V DC) is first applied to the RWD, the red and green LEDs flash once to indicate successful power-up. The device can also check for a broken or shorted antenna and can even detect very badly tuned antennas, these problems are indicated by the red LED flashing continuously until the fault has been rectified. - Page 8 Power supply from USB, PCB antenna mode, Hitag 2 mode, no tag in RF field, Red LED (LED1) on Power supply from USB, PCB antenna mode, Hitag 2 mode, Hitag2 Tag in RF field Green LED (LED2) on By default the green LED (LED3) lights when the board is powered but it can pulses when transmitting or receiving data via USB.
- Page 9 The main window of the MicroRWD Quad Tag software is presented below. The RWD SMT baseboard is not connected to a PC and MicroRWD status is: “COM PORT NOT OPEN”. When the baseboard is properly connected to a PC then the MicroRWD status should be: „CONNECTED”. If not, try clicking “Configure”...

Page 10: Application Notes
4 Application notes 1. An external antenna can be mounted up to 1.5 meters from the RWD SMT baseboard. Screened twisted pair cable should be used with the screen connected to GND. The RWD Baseboard with external antenna coil is shown below. - Page 11 The RWD QT SMT soldered right to the Baseboard PCB The RWD QT SMT mounted with 2x pin headers and 2x female headers.
