2 General
2.1 Basic Specification
Table 1 shows Reader/Writer “RC-S44x” models. RC-S445 has dual CPUs and
external memories for sub CPU . RC-S441 is a singl e CPU type same as th e models
RC-S430 and RC-S480.
Reader/Writer consists of 3 parts – an antenna board, an RF/control board and the
cable that connects the antenna board and the RF/control board. There are 2 antenna
types called Type C and E (see Chapter 6).

2.1.3 Encryption Technique
All communications to and from the Card, with the exception of Polling Command,
are encrypted.
All the communications to and from the Controller, with the exception of the
Attention Command, are encrypted.
Two kinds of Encryption algorithm, Single-DES 56bit and Triple-DES 56bit can be
applied.

3.1 Connection with Controller
The pin assignment is desc r ibed in Chapter 6.
3.2 Transaction Overview
3.2.1 Communication Protocol
There are two communication protocols, namely, data link level and application level
protocol.
Either ACK or NACK packet is returned in every packet transfer. ACK indicates a
successful transfer, NACK means unsuccessful.
Fig. 1 : Communication Protocol and Packet St ruct ure
3.2.2 Re-sending Protocol
Reader/Writer support s t he re-sending procedure in Controller interface. Re-sending
handling is triggered or requ ired in the two cases below :
1. NACK packet is returned.
2. Neither ACK nor NACK response co mes. (t ime out)
Controller should re-send the same packet within 5ms after receiving NACK or
detecting time out.
3.2.3 ACK / NACK Packet
ACK / NACK packet format is as follows :
ACK : LEN = 00h & LCS = ffh without Packet Data part and DCS
NACK : LEN = ffh & LCS = 00h without Packet Data part and DCS
3.2.4 Mutual Authentication
Mutual Authentication is a process that is performed between Controller and
Reader/Writer to authenti cat e each other mutually in order to avoid the fraud usage.
