RDM880 SERIAL MODULE:
OEM & ODM ISO14443A/B, ISO15693, ISO11784/11785 MODULE
DEVELOPMENT KIT
1 RS232 or SPI OPERATIONS
The OEM & ODM ISO14443-A-B, ISO15693, ISO11784 /11785 MODULE can operate with a
terminal such as computer or other controller, which can supply RS232 or SPI interface.
1.1 Electrical Interface
Basically, this communication protocol does not need to be bound with any electrical interface
characteristic. Typically the following types of physical link could be used:
• RS232 (Point to point only)
• CMOS-Logic Level (Point to point only)
• SPI (Slave only)
1.2 Data Format
The data format (Start Bit, Data Bits, parity, Stop Bit) is software configurable, and can be set to
match the special requirement of data transmission between two communication devices. The
general data format is defined as:
Parameter Description
Baud Rate Selective: 9600, 19200, 38400, 57600, 1152000
(It can be changed by command Send from the Host)
Data Bits Fixed: 8 bits
Start Bit Fixed: 1 Bits
Stop Bit Selective: 1 bit.
Parity None
The following is the default setting (RS232):
Baud Rate Data Bits Start Bit Stop Bit Parity
9600 8 1 1 None

2 Link Layer
The communication protocol is a packet-oriented protocol - all the data exchanged between two
communication devices will be based on packet format. The protocol is designed for multi-drop
mode and where point-to-point mode could be treated as a special case of multi-drop mode.
The data packet starts with the control character ‘STX’ and ends with ‘ETX’, which follows the 8-bit
BCC checksum. Besides the checksum is used for error checking, character (byte) time-out and
packet (command) time-out are used to re-synchronous the communication.
2.1 Packet Format
There are two types of data packets. Command Message is the packet Send from the Host to the
reader device. The Reply Message is the packet Send from the reader to the Host.
Packet format for Command Message (Host to Reader)
STX STATION ID DATA LENGTH CMD DATA[0..N] BCC ETX
Packet format for Reply Message (Reader to Host)
STX STATION ID DATA LENGTH STATUS DATA[0..N] BCC ETX
