1.2 System Overview The UART-B1 device is an extension of our RFID B1 module. Below, In Figure 1-1 the System Diagram is presented. PCB RFID Antenna UART and Power Input Connector (J1/J2) UART +3.3V RFID B1 Module ANT Signals RFID Antenna Switch (J8 and J9) IO + Peripherals Header Connector (J3) External RFID Antenna Connector (J10) Figure 1-1 System Diagram 1.

1.4.2 External Antenna Connector (J10) The user has the option to work with an external RFID antenna connected to the USB-B1 device. Connector J10 is where this should be connected. Eccel Technology Ltd provides a variety of RFID antennas which the user can use together with this device. J10 – External Antenna Socket 1.4.3 External / PCB Antenna Selection Connectors J8 and J9 To switch between the PCB antenna and an external antenna, two jumpers have to be used with the J8 and J9 connectors.

1.4.4 IO and Peripheral Configuration Header The device PCB connects the pins on this header to all IOs and peripherals provided by the onboard RFID B1 module and a few pins are available providing +3.3V and GND signals. J3.1 – GPIO 0 J3.2 – GPIO 2 J3.3 – GPIO 1 J3.4 – GPIO 3 J3.5 – GND J3.6 – 3.3 V J3.7 – IDAC (Digital to Analog Converter with current-type output) J3.8 – GND J3.9 – COMP (Comparator positive input) J3.10 – GND J3.11 – ADC (Analog to Digital Converter input) J3.12 – GND J3.13 – GND J3.

3. Installation and operation From the system and functionality point of view, the UART-B1 device provides the same features as the RFID B1 module, and the user should refer to the RFID B1 User Manual when working with the UART-B1. For a quick test the user can also use a UART-USB converter and simply connect the UART-B1 to a computer e.g. TTL-232RG-VSW3V3-WE (FTDI) or similar and then start the B1-client application which allows the user to test all features of the device.
PAGE 13
The UART-B1 can also operate in a stand-alone mode. The user can control all GPIO’s and add tags to the whitelist (a list of defined tags). For easy configuration of polling parameters we provide the B1 Stand-Alone Configurator application which can be downloaded from here. This application allows the user to simply search for a new tag, add it to the whitelist, configure polling parameters, enable/disable all of GPIOs and control them. For more information please refer to the RFID-B1 User Manual.
