1. Introduction
The A828US OEM UHF compact reader (FCC part 15), is a CAEN multi protocol OEM
compact module for integration into barcode printers, printer applicators, handheld
computers and PDAs, devices requiring UHF tag programming and reading.
The A828US is fully compliant to the US telecommunication regulation FCC part 15 (902-
928 MHz).
Currently the A828EU 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 GPIO0-GPIO4 pin are 5 general purpose bidirectional pins, their default direction (or
after a Reset) is Out; GPIO4 works also as Identify Tag signal. the Wakeup pin (active
low) must be used when the A828US board is put into power down mode.
The RXD/TXD pins are used to communicate with the A828US board via UART port; to
establish a link with the device you must configure your COM port as follows:
1. Baud rate : 115200
2. Parity : None
3. Data bits : 8
4. Stop bits : 1

2.2.2. Regulatory Compliance
This equipment has been tested and found to comply with Part 15 of the FCC Rules.
NOTE:
(a) Any changes or modification not approved by CAEN RFID could void the user’s
authority to operate the equipment.
(b) The A828US Module, which is rated at 50 mW output, cannot use an antenna with
more than 16 dBi of gain. Use of any other antenna with a gain greater than 16 dBi may
void the user’s authority to operate the equipment.
