1. Introduction
The A829US is a multi protocol fully integrated UHF low power short range reader
designed specifically to be used in desktop or embedded RFID application.
The A829US is fully compliant to the US telecommunication regulation FCC part 15
(902-928 MHz) and it is the reader solution to solve the problem of proximity
reading/writing of tags and labels, where transponders are up to 1 metre distance from
the reader.
Currently the A829US Module supports the ISO18000-6 B, the Philips UCODE EPC 1.19
and EPC Class1 Gen2 protocols. Other future UHF protocols will be available by
firmware upgrade. The A829US houses an integrated antenna, and an USB interface for
PC connection. It is a bus powered USB device designed to operate as a stand alone PC
peripheral communicating via an USB serial port.
