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. The
B1-client along its user guide can be downloaded from here. The best read range can be achieved when the tag is
parallel to the surface of the reader (see Figure 3-1). There is also LED1 (green) which indicates a tag presence in the
antenna field.
