1.0.Introduction
The ACS Smart Card Reader/Writer ACR30 is an interface for the communication between a
computer (for example, a PC) and a smart card. Different types of smart cards have different
commands and different communication protocols. This prevents in most cases the direct
communication between a smart card and a computer. The ACR30 Reader/Writer establishes a
uniform interface from the computer to the smart card for a wide variety of cards. By taking care of the
card specific particulars, it releases the computer software programmer of getting involved with the
technical details of the smart card operation, which are in many cases not relevant for the
implementation of a smart card system.
The ACR30 Smart Card Reader/Writer is connected to the computer through a serial asynchronous
interface (RS-232) or USB interface. The reader accepts commands from the computer, carries out
the specified function at the smart card and returns the requested data or status information.
NOTE - Although the ACR30 is a true card reader/writer as it can read and write smart cards, the terms card reader or reader
will be used indifferently to refer to the ACR30, for the sake of readability and because these designations are commonly in use
for this kind of devices.

Siemens SLE 4418/4428 intelligent 1K bytes EEPROM with write-protect function:
SLE 4418, SLE 4428
NOTE (*) –SAM READER DOES NOT SUPPORT FOR MEMORY-BASED SMART CARD
3.2. Microcontroller-based smart cards (asynchronous interface)
The ACR30 supports EEPROM microcontroller-based cards with internal programming voltage (VPP)
generation and the following programming parameters transmitted in the ATR:
PI1 = 0 or 5
I = 25 or 50
The ACR30 performs the Protocol and Parameters Selection (PPS) procedure as specified in
ISO7816-3:1997.
When the card ATR indicates the specific operation mode (TA2present; bit b5 of TA2must be 0) and
that particular mode is not supported by the ACR30, the reader will reset the card to set it to
negotiable mode. If the card cannot be set to negotiable mode, the reader will reject the card.
When the card ATR indicates the negotiable mode (TA2not present) and communication parameters
other than the default parameters, the ACR30 will execute the PPS and try to use the communication
parameters that the card suggested in its ATR. If the card does not accept the PPS, the reader will
use the default parameters (F=372, D=1).
For the meaning of the aforementioned parameters, please refer to ISO7816, part 3.

ACR30
4.0.Smart Card Interface
The interface between the ACR30 and the inserted smart card follows the specifications of ISO7816-3
with certain restrictions or enhancements to increase the practical functionality of the ACR30.
4.1. Smart Card Power Supply VCC (C1)
The current consumption of the inserted card must not be higher than 50mA.
4.2. Programming Voltage VPP (C6)
According to ISO 7816-3, the smart card contact C6 (VPP) supplies the programming voltage to the
smart card. Since all common smart cards in the market are EEPROM based and do not require the
provision of an external programming voltage, the contact C6 (VPP) has been implemented as a
normal control signal in the ACR30. The electrical specifications of this contact are identical to those
of the signal RST (at contact C2).
4.3. Card Type Selection
The controlling PC has to always select the card type through the proper command sent to the ACR30
prior to activating the inserted card. This includes both the memory cards and MCU-based cards.
For MCU-based cards the reader allows to select the preferred protocol, T=0 or T=1. However, this
selection is only accepted and carried out by the reader through the PPS when the card inserted in
the reader supports both protocol types. Whenever an MCU-based card supports only one protocol
type, T=0 or T=1, the reader automatically uses that protocol type, regardless of the protocol type
selected by the application.
4.4. Interface for Microcontroller-based Cards
For microcontroller-based smart cards only the contacts C1 (VCC), C2 (RST), C3 (CLK), C5 (GND)
and C7 (I/O) are used. A frequency of 3.6864 / 4 MHz is applied to the CLK signal (C3).
4.5. Card Tearing Protection
The ACR30 provides a mechanism to protect the inserted card when it is suddenly withdrawn while it
is powered up. The power supply to the card and the signal lines between the ACR30 and the card
are immediately deactivated when the card is being removed. As a general rule, however, to avoid
any electrical damage, a card should only be removed from the reader while it is powered down.
NOTE - The ACR30 does never by itself switch on the power supply to the inserted card. This must explicitly be done by the
controlling computer through the proper command sent to the reader.

ACR30
5.0.Power Supply
The ACR30 requires a voltage of 5V DC, 100mA regulated power supply. The ACR30 gets the power
supply from PC (through the cable supplied along with each type of reader).
Status LEDs- Green LED on the front of the reader indicates the activation status of the smart card
interface.
Green LED - Indicates power supply to the smart card is switched on, i.e., the smart card is activated.

6.0.Serial Interface
The ACR30 is connected to a computer through a serial asynchronous interface following the RS-232
standard.
6.1. Communication Parameters
The following communication parameters are used by the ACR30 and cannot be modified by the host
computer:
The ACR30 provides two means to select the transmission speed (baud rate) used by the reader in
the normal operation, by hardware and/or by software.
6.1.1. Hardware Baud Rate
The default hardware baud rate setting is 9600 bps.
6.1.2. Software Baud Rate Selection
The SET_PROTOCOL command allows setting the transmission speed (baud rate) and a delay time
inserted between the bytes transmitted by the reader to the PC.
Please note that the setting made with this command is volatile and will be lost when the reader is
being reset or powered up next time.
6.2. Interface Wiring
For the communication between the ACR30 and a computer, five lines of the RS-232 interface are
used: RxD, TxD, CTS, DTR and GND.
