PRODUCT OVERVIEW

1

The Motorola Card Acceptance Device (CAD) is an electronic module capable of communicating with
ISO 14443 Type A and Type B compatible smart cards via a radio frequency (RF) interface. This
section provides general information about the application and physical properties of the CAD.

Physical Description

Overview

The CAD, which provides the communications interface between a
terminal and customer smart cards, consists of a Control Board and
an Antenna Board. These two boards are connected together by a
100 mm multiconductor interconnect cable. The CAD is connected
to the terminal via a 16pin connector (parallel models) or a 10pin
connector (serial models) located on the Control Board.

Control Board

The Control Board contains a microprocessor, nonvolatile memory,
and radio frequency transmitting and receiving circuitry. This board
communicates with smart cards via an RF link (provided by the
Antenna Board), and to the terminal via RS232, RS485, or CMOS
(serial models) or a bytewide, proprietary parallel (parallel models)
protocol. Note that serial rates range from 9600 bps to 115.2 kbps,
and parallel rates are up to 25 kbytes/sec.

Typical Application

Antenna Board

The Antenna Board consists of a printed circuit board with copper
traces forming the transmit and receive antenna. The Antenna
Board may be one of several types, varying in dimensions and
construction (some types are attached to a ferrite plate with a metal
back plate serving as a ground plane).

The CAD described in this manual is a device which allows
communications to contactless smart cards by a host or terminal. It
is suitable for applications such as automated fare collection,
access control, electronic purse, and vending machines.

The illustration on the facing page shows a simplified block diagram of the CAD. This section is
intended to provide a basic understanding of the CAD circuitry and how it interacts with the terminal
and smart cards. (Refer to Chapter 4 for a more detailed block diagram and circuit descriptions.)

SIMPLIFIED BLOCK DIAGRAM THEORY

Overview of CAD
Operation

The CAD serves as the data communications link between a smart
card and the Terminal in which the CAD is installed (or to which the
CAD is connected). The CAD operations are controlled by the
Terminal. The CAD searches (polls) for smart cards within its range,
notifies theTerminal when valid cards are found, and transfers data
from the Terminal to the card, and from the card back to the
Terminal.

For TerminaltoCard communications, the CAD's Control Board
receives a command from the Terminal to transmit data (received
from the Terminal) to the card. The CAD then transmits the data via
modulated encrypted RF signals to the card.

For CardtoTerminal communications, the CAD's Control Board
detects and demodulates encrypted RF data signals from the smart
card and sends data back to the Terminal. Communications with
the Terminal are made using RS485, RS232, or CMOS (serial
models) or 8bit bytewide parallel (parallel models) protocols.

TUNING PROCEDURE

3

Introduction

Each CAD set is tuned at the factory for maximum operating range with minimal power. However, in some
cases it may be necessary to tune the CAD set again when it is installed in the terminal due to
characteristics of the terminal (such as metal or metallic paint near the Antenna Board) which can affect
the operating range or reliability. It may also be required to tune the CAD set again if a terminal (such
as a batterypowered terminal) requires minimal power draw from the CAD and a nominal operating
range.

CAD Tuning Guidelines

If the CAD set requires tuning due to Terminal characteristics such as metal or metallic paint near the
Antenna Board (which can affect operating range or reliability), it is recommended that the CAD be
installed into the Terminal first and then tuned. This may require some special adapters (e.g., to connect
the CAD to the PC).

However, there may be situations where tuning the CAD while installed in the Terminal is not possible
(e.g., access to the tuning capacitor is not possible while installed in the Terminal housing). In these
cases, a special tuning fixture" may have to be constructed to simulate the CAD installed in the Terminal
housing while also providing access to the tuning capacitor. The fixture must be constructed so as to
simulate any metal shielding in the Terminal, as well as the precise distance between a presented smart
card and the Antenna Board. For further assistance in constructing a tuning fixture, consult with the
Motorola System Support Center.

If, instead, the Terminal has little or no effect on the CAD performance and the CAD needs to be adjusted,
this can be done prior to installation in the Terminal. In cases such as this, tuning may be performed on
a test bench with the distance between the Antenna Board and the Terminal card presentation target
simulated. The tuning procedure beginning on page 2-12 describes this method.

NoteTo perform the tuning procedure, you will use the CADTools program. This software application
was used previously to perform the SelfTest utility to verify that the CAD is electrically functional. Refer
to page 2-4 for instructions on installing this software application on your PC.

INSTALLING CAD INTO TERMINAL

4

The information in this section describes the typical mounting methods for installing a CAD set into a
Terminal.

NoteRefer to Appendix B for pinout details of the CAD connectors, and Appendix C for physical
dimensions and clearances.

Mounting Methods

Introduction

The CAD may be mounted in one of two ways:

 Stacked
 Separated

Each of these mounting methods is described below.

Stacked" Mounting Method

The Control Board and the Antenna Board have been designed so that
they may be stacked as shown on the facing page. The mounting holes
line up with each other, and may be used with screws and spacers to
secure the CAD to the terminal chassis.

Note that the two boards may be stacked so that the metal shields on the
Control Board are either touching or not touching the metallic surface of
the Antenna Board.

Separated" Mounting Method

The 100 mm cable allows the Control Board and the Antenna Board to
be separated to accommodate various mounting scenarios, as shown
on the facing page.

Other Things You Should Know

 The nonmetallic side of the Antenna Board must face towards the

card reading surface of the terminal.

 The Antenna Board should be mounted as close as possible to the

Reader target area.

 The Antenna Board should be located at least 15 mm (in all

directions) from any metallic materials.

 Route the multiconductor interconnect cable away from any

metallic materials. Also, dress and secure cable to prevent
movement.

Once the CAD has been tuned and installed into the terminal, a final checkout procedure must be
performed to ensure that the CAD can communicate with a compatible SmartCard. Once this final
checkout has been performed, the terminal may be placed into service.

FINAL CHECKOUT PROCEDURE

Required Equipment

The following hardware and software is required to perform the final
checkout procedure:

 Compatible SmartCard (e.g., Model MV4000D)
 Powered terminal with CAD installed

Performing the Final
Checkout Procedure

Place an active SmartCard (one that has been initialized and
personalized for use with the particular terminal application) within
reading distance and verify that the desired results are achieved. For
example, for a transit application, the terminal should generate a receipt
ticket (or some other verification, such as a `'beep" or light, that the
transaction was successful).

There are four basic techniques for isolating the CAD as the source of a faulty terminal:

 Verify dc power from the terminal (+12 V dc)

 Observe LED Indicator on the Control Board

 Perform the Self Test diagnostics checkout procedure

 Perform the Tuning Procedure

Verify DC Power

With the terminal turned on, the CAD should be receiving
+12 V dc on the following pins:

 Parallel CAD+ Pins 1 and 2 of the 16pin parallel

connector located on the Control Board (use pin 3 or
4 as ground)

Verify LED Indicator

 Serial CAD+ Pin 3 of the 10pin serial connector

located on the Control Board (use pin 2 as ground)

Verify that the voltage is present using a digital voltmeter. If the
dc voltage is not present:

 Make sure the cable from the terminal is securely attached

to the 16pin (parallel) or 10pin (serial) connector on the
Control Board.

 Troubleshoot the terminal to determine source of faulty

+12 V dc.

A green LED is provided on the Control Board to provide a visual
indication that the Control board has received dc power and has
successfully performed its startup routine. If this LED is not lit
after applying power:

The following theory of operation describes the operation of the CAD circuitry at a functional level. The information
is presented to give the service technician a basic understanding of the functions performed by the CAD in order
to facilitate fault isolation. Refer to Figure 1 for a block diagram of the CAD.

FUNCTIONAL THEORY OF OPERATION

Microprocessor Circuitry

Overview

The CAD uses a Motorola ColdFire MCF5204 microprocessor (P)
which serves as the main controller for the CAD. The microprocessor,
running at a clock speed of 18.432 MHz (generated by an external
clock circuit) controls the operation of the CAD as determined by the
CAD software contained in the FLASH memory.

Address and Data Buses

The P is equipped with a 32bit address bus used to access the
memory (FLASH and SRAM) and provide control (via memory map
ping) for other circuitry in the CAD. A 16bit data bus is used to transfer
data to/from the P, memory, and the AFE.

Reset Circuit

A Low +5V Detect circuit monitors the level of the +5V supply voltage
and generates a reset signal if it falls below a threshold level. The reset
signal is sent to the P, the I/O Register, the AFE, and FLASH memory.

A hardware reset can also be initiated from both the Serial and Parallel
connectors by applying a low active pulse (1 sec minimum) on the
EXTERNAL_RST# line of either connector.

NonVolatile Memory Circuitry

4-2

FLASH Memory

The CAD software resides in a 256k x 16 FLASH memory IC. The
FLASH memory is accessed by the P via the 32bit Address Bus and
the 16bit Data Bus.

SRAM Memory

To supplement the P's internal 512 bytes of internal SRAM, a 32k x 8
SRAM IC is provided.

The Analog Front End (AFE) circuitry operates under control of the P

 Controls the power output to the antenna

 Modulates TX data and sends to card (via Antenna Board)

 Receives (via Antenna Board) RX data from card and provides

demodulation

The CAD Control Board contains onboard regulators and filtering cir
cuitry to generate the various voltages required by the CAD circuitry.
+12 V from the terminal (via connector P8) is used as the source to
generate +5V and +5V_A supply voltages. Also, the variable PA_PWR
supply voltage is generated and fed to the Power Amplifier (p/o AFE)
to control the RF output power of the CAD.

Antenna Board

Serial Interface Circuitry

The Antenna Board consists of a printed circuit board (with traces that
form the antenna), a ferrite plate (which magnetically shields the anten
na from the Control Board), and a metal back plate (which electrically
shields the antenna from the Control Board). The Antenna Board is
connected to the Control Board by a 6wire cable.

The CAD+ Control Board supports a variety of serial protocols
(RS485, RS232, and CMOS). In order to accomplish this, the Serial
Interface Logic Circuitry routes the desired transmit and receive data
to/from the 10pin Serial Connector as determined by the settings on
an 8position DIP switch located on the board.

TERMINALTOCAD COMMAND PROTOCOL

1

This section defines the structure of commands initiated by the terminal for transmission control and for
specific control in asynchronous halfduplex transmission protocols. Block protocol type ISO 78163 T=1
is used.

The command structure (shown below) consists of the following blocks:

 prologue field

 information field

 epilogue field

The prologue and epilogue fields are mandatory, and must be sent in every case. The information field
is optional. The number of bytes of the information field is indicated by length (LEN) byte (part of the
prologue field).

The PCB byte in the Prologue field serves to control and
supervise the transmission protocol. The PCB byte encodes first
and foremost the block type, as well as supplementary data
needed in this context. The PCB byte information for an Iblock,
an Rblock, and an Sblock are shown below.

Information Field (INF)

The presence of INF is optional. When present, INF conveys
either application data in Iblocks for cards, miscellaneous data
for the CAD or nonapplication control and status information in
Sblocks.

In an Sblock, this field is used for the management of the CAD.
The CAD does not support the exhaustive list of SBlocks defined
in ISO 7816-3 T=1. However, the CAD supports Motorola
proprietary definition of SBlocks as commands for
management.

Rblocks do not contain an INF field.

Epilogue Field

This field contains the error detection code (EDC) of the
transmitted block. The protocol definition permits this to be either
an LRC or a CRC. The LRC is calculated as the exclusive OR
(XOR) of all the bytes starting with the NAD through the last byte
of the information field, and is typically referred to simply as the
checksum. For CRC see ISO 3309. The CAD uses the CRC.

ANSWER TO RESET (ATR)

2

After cycling the power supply or software reboot, the CAD sends out an ATR. For serial transmission,
the ATR is sent at 9.6 Kbps and then the CAD switches to its programmed baud rate (from 9.6 Kbps to

230.4 Kbps). For parallel transmission, the rate is synchronous. The ATR is a data string, up to 33
bytes long, which contains various data relevant to the transmission protocol and to the card. The
ATR's data string and data elements are defined and described in detail in ISO/IEC 7816-3.

ATR Format

The basic ATR format consists of:

 TS  one byte, the initial character; specifies the con

ventions to code data bytes in all subsequent charac
ters. There are two possible values of TS (ten consec
utive bits from start to end and corresponding hexade
cimal value). The CAD uses direct convention:
(Z)AZZAZZZAAZ(Z) where logic level ONE is Z (LSB
is first). It equals to "3B" when decoded by direct con
vention.

 T0  one byte, the format character; serves to indi

cate the subsequent "interface character" a bit field is
used, from b5 to b8. It further contains the number of
subsequent "historical characters," from b1 to b4.

T0 Byte Information

POLL

POLL request

Description

This command makes the CAD switch to the card detection/anti-collision
sequence. The card must be out of the RF field before sending a Poll request.

The STRAT byte supports two options that order the CAD to detect all cards (Long
Poll) or the first card (Quick Poll) in the RF field.
As the CAD manages the attribution of the NAD for the cards detected in the field,
it reserves NAD values that are already in use and gives free NAD values to a new
card that is detected. But the CAD has no information about the transactions
between the terminal and the card(s). Thus, when the terminal has completed all
the transactions with the card(s) registered, it may indicate to the CAD that the busy
values can be freed or not by setting the appropriate value in the ERASE field.

The TYPE byte of this command indicates to the CAD which type of application
of contactless card in the field must be selected.

ANSWER TO POLL

ANSWER TO POLL request

There is no ANSWER TO POLL request.

ANSWER TO POLL response

Description

When a card is successfully registered in the CAD (the card answered correctly
to the REQUEST/SLOT MARKER or ATTRIB frames), the CAD sends this frame
to the terminal to indicate that a new card is to be registered. For a long poll,
the CAD responds with as many Answer To Poll messages as the number of
cards polled. The Answer To Poll response frame transports all necessary
information about the card and the card-terminal link.

The NEW NAD byte is the value of the NAD that will be used by the terminal and
the card during the transaction. This NAD is ISO 7816-3 T=1 compliant. The
terminal must use the value received in the Answer To Poll response to send data
to the card, without inverting the most significant and the least significant nibble
of the byte. Once the Terminal sends a command with the new NAD (other than
0x11), the CAD sets the data transmission to Pipeline Mode that allows the
Terminal to directly communicate to the card (and visa versa). This process may
continue until the CAD receives its own NAD (0x11) from the Terminal.

The four-byte PUPI field identifies formally the card. The terminal may use it to
detect non-valid cards.

The HB field may be n bytes long (0-15) and is the exact image of the Historical
Bytes field of the card ATQ frame.

DETECT CARD

DETECT CARD request

Description

After a Quick Poll command, the DETECT CARD command may be sent by the
terminal to know if there are additional cards in non-application phase in the RF
field. After this command, the CAD sends a REQUEST command parameterized
with 1 slot through the RF field. Consequently, if one or more additional cards are
present in the RF field, it must answer to the REQUEST command. The card which
is communicating with the Terminal will not answer to the REQUEST if it has
received a DESELECT command (see ISO/IEC 14443-3).

The TYPE byte of this command indicates to the CAD which type of application
of contactless card in the field must be detected.

Whatever is the result of the detection (nothing, a collision or a correct answer),
the CAD uses the CARD PRESENCE command to indicate the result of this
detection sequence.

NoteSince this command is to be sent after a Quick Poll command, do not try to
send this command under any other circumstances (like immediately after reboot).

FLASH UPGRADE PROCEDURE

1

Operating software for the CAD+ is stored in FLASH memory on the Control Board. The software may
be upgraded (or reinstalled) by using the Firmware Download utility included as part of the CADTools
software program (provided with the appropriate Parallel or Serial CAD Installation Kit).

NoteCADTools V1.20 or higher is required for use with the CAD+.

Preparing for Upgrade
Procedure

Locating CAD Operating Software

The upgrade process installs CAD operating software (stored on
the PC hard disk or floppy diskette) into FLASH memory on the
CAD Control Board. Before you begin the upgrade procedure,
make sure you have available the desired version of CAD software.
It is recommended that you copy this software into the following
location on the PC hard disk:

Performing FLASH
Upgrade Procedure

C:\Program Files\CADTools

(Since the Firmware Upgrade utility automatically looks in this
directory first for CAD operating software, locating the software here
will streamline the process as well as provide one central directory
in which to store all of your CAD operating software versions.)

Setting Up the CAD and PC

Connect the CAD to the PC and launch the CADTools program as
described in Launching the CADTools Software on page 2-5 of this
manual.

Refer to the CADTools User's Guide (provided with the CADTools
software package) for stepbystep instructions for performing a
FLASH upgrade procedure.
