INTRODUCTION
The ACR122S is a PC-linked Contactless Smart Card Rea der/Writer developed on the
13.56MHz Contactless Technology. This device is designed to support not only MiFare
and ISO14443 Type A and B Cards but also FeliCa and NFC tags.
By making use high-speed card access and Serial port speed of 115.200 Kbps, read and
write operations are faster and more efficient. With its compact size and trendy design
and with the various features the ACR122S offers,you can experience the convenience in
using ACR122S for applications of payment,mass transit, physical access control, time
attendance, etc.

Installation Procedure
Connect the ACR122S DB9 cable to the PC serial port and plug the USB cable into the
USB port. The USB is provided the power only. When the reader connects to the PC,
then the user can use it directly. It doesn’t need any windows driver to start up the reader.

Hardware Interfaces
5.1 Bi-Color LED
•
User-controllable Bi-Color LED. Red and Green Color.
•
•
•
•
The Green Color LED will be blinking if the “Card Interface” is not connected.
The Green Color LED will be turned on if the “Card Interface” is connected.
The Green Color LED will be flashing if the “Card Interface” is operating.
The Red Color LED is controlled by the application only.
5.2 Buzzer
•
•
User-controllable buzzer.
The default Buzzer State is OFF
5.3 SAM Interface
•
One SAM socket is provided.
5.4 Built-in Antenna
•
•
•
•
•
3 turns symmetric loop antenna.Center tapped.
The estimated size = 50mm x 40mm.
The loop inductance should be around ~ 1.6uH to 2.5uH
Operating Distance for different Tags ~ up to 50mm (depend on the Tag)
No anti-collision. Only one Tag can be accessed at any one time.

Serial Interface (CCID-liked FRAME Format)
Communication setting: 9600 bps, 8-N-1
The communication protocol between the Host and ACR122S is very similar to the CCID
protocol.

Checksum = XOR {Bulk-OUT Header, APDU Command or Parameters}
Checksum = XOR {Bulk-IN Header, APDU Response or abData}
In general, we would make use of three types of Bulk-OUT Header.
• HOST_to_RDR_IccPowerOn: To activate the SAM interface. The ATR of the SAM will be
returned if available.
• HOST_to_RDR_IccPowerOff: To deactivate the SAM interface.
• HOST_to_RDR_XfrBlock: To exchange APDUs between the Host and ACR122S-PM.
#The SAM interface must be activated in order to use the Contactless interface and
Peripherals. In short, all the APDUs are exchanged through the SAM Interface.
Similarly, two types of Bulk-IN Header are used.
• RDR_to_HOST_DataBlock: In response to the “HOST_to_RDR_IccPowerOn” and
“HOST_to_RDR_XfrBlock” Frames.
• RDR_to_HOST_SlotStatus: In response to the “HOST_to_RDR_IccPowerOff” Frame.
RDR=ACR122S,HOST=Host Controller.
HOST_to_RDR=Host Controller->ACR122S
