1. Introduction
RE31 is a single chip reader IC for 13.56MHz RFID/contactless standard protocols including
ISO14443A/B, ISO15693. The HiRead-R provides a hi-speed SPI controller/host interface with a
built-in 64-byte FIFO for smooth data transfer.
Silicon Craft Technology PLC. (SIC) creates this document to describe how to enable RE31
Mini Reader with PC. This mini reader connects to PC via UART connection.

2. Getting Start
Before user can operate RA12 Mini Reader, proper operational environment and the
following requirements must be prepared.
2.1. System and Hardware Requirements
•Computer : PC with USB Port
•Operating System : Window XP, Window 7, 8, 10
•Software Requirement : Hyper Terminal, Tera Term, Putty, MobaXterm, etc.
•Others : ISO14443A/B or ISO15693 Card or Tag.
2.2. Software Setup
2.2.1. Serial Communication Configuration
To communicate with the reader, user must establish a serial connection. The setting
below is to config the serial session to match the reader communication configuration.
•Serial Port : Select COM Port which match to USB to UART converter
•Baud Rate : 115200 bps
•Data : 8 bits
•Parity bit : None
•Stop bit : 1 bit
2.2.2. Terminal Software (MobaXterm)
To interact with the reader, a terminal software is needed. Generally, any terminal software
is compatible. However, we will use MobaXterm as an example terminal software to communicate
with the reader in this case.

To refer to a register address, a hexadecimal number proceeding with “0x” is used, for example
0x05 refer to a register address 0x05.
To refer to a bit located in a register address, a symbol “.” following by a number reflecting
the bit location starting from 0 to 7 is used. For example, 0x05.2 refers to bit 7, MSB, in the register
address 0x05.
To refer to a set of consecutive bits located in a register address, a format “.[MSB:LSB]” is
used after a register address . For example, a value of 0x05.[3:0] refers to bit 3, 2, 1 and 0 in the
register 0x05.
To refer to a binary value in some registers, the letter “b” is placed at the end of binary
number. For an example “0101b”.
To refer to logic level, the number in single quote ‘1’ and ‘0’ are used to refer to binary logic
level.
