FCC AND CE COMPLIANCE

Federal Communications Commission (FCC) Part 15 statement

This equipment has been tested to FCC requirements and has been found acceptable for
use. The FCC requires the following statement for your information :
This equipement generates and uses radiofrequency energy and if not installed and used
properly, that is, in strict accordance with the manufacturer ’s instructions, may cause
interference to radio and television reception. It has been tested and found to comply with
the limits for a Class B computing device in accordance with the specifications in part 15
of FCC rules, which are designed to provide reasonable protection against such interference
in a residential installation. however, there is no guarentee that interference will not occure
in a particular installation. If this equipment does cause interference to radio or television
reception, which can be determined by tuning the equipment off and on, the user is
encouraged to try to correct the interference by one or more of the following measures:

• If using an indoor antenna, have quality outdoor antenna installed

• Reoriant the receiving antenna until interference is reduced or eliminated

• Move the radio or television receiver away from the receiver/control

• Move the antenna leads away from any wire runs to the receiver/control

• Plug the receiver/control into a different outlet so that it and the radio or television

receiver are on different branch circuits.
This device complies with part 15 off the FCC rules. Operation is subject to the following

two conditions : (1) this device may not cautse harmful interference, and (2) : this device
must accept any interference received, including interference that may cause undesired
operation.

If necessary , the user should consult the dealer or an experienced radio/television technician
for additional suggestions. The user or master may find the following booklet prepared by
the Federal Communication Commissions helpful: «Interference Handbook».
This booklet is available from the US Government Printing Office, Washington, DC 20402.

The user shall not make any changes or modifications to the equipment unless authorized
by installation instructions or User’s Manual. Unauthoriezd changes or modifications could
void the user’s authority to operate the equipment.

USB Interface

Communication with the reader is done using a serial protocol through USB interface.

PC drivers installation

! Plug the coupler
! At PC request for driver , choose the one supplied with the ACCESSO kit (CD Rom).

Baud rate

The default data rate is set at 9600 bauds, but this can be changed by software to select
lower data rates :

! 9600 (default value)
! 1 15200

Coupler’s Inputs and Outputs

ACCESSO and M260H has no input, and one output for the embedded LED.
This LED is controlled by software and can have the following colors :

• Green

• Orange

• Red

Use the Set Status command to control the LED control.

How to reset the coupler

Resetting the coupler may be useful to set the parameters (speed, disable mode, protocol
settings, keys ) to the defaults values. All these values are stored in coupler’s internal
EEPROM

Software reset

It is possible to reset the coupler’s EEPROM by sending 2 commands thanks to the SET
ST ATUS command.

Command = $80,$F4,$80,$3E,$01 - Data = $00
Command = $80,$F4,$80,$7E,$01 - Data = $00

Then the coupler has the default setting : 9600 bds, defaults protocols....

HOST - COUPLER protocol

DESCRIPTION

The commands are modeled on the ISO 7816 command set. This protocol is used by all
INSIDE’s couplers

A typical protocol exchange includes:

1.The host sends a command to the coupler

2.The coupler executes the command

3.The host receives a response from the coupler

Coupler command is always constituted of 5 bytes :

• CLASS : always 80h

• INSTRUCTION : command to be executed by the coupler (like SelectCard)

• P1 : Command parameter

• P2 : Command parameter

• P3 : Command parameter

Depending on the command, coupler answers data, status words.
There are 4 cases of data exchange:

Case Host to coupl er Coupler to Host ISO Type

1 None None ISO None
2 None Yes ISO O ut
3YesNoneISO In
4 Yes Yes ISO In / Out

Note : In case 4, dat a has to be sent and received from the coupler. With T=0 protocol, it
is not possible in a single command, so this command has to be split into 2 commands:

Coupler - Reference manual

Version 1.1

RM 2

ISO In : The host sends a command + data and receives the status words.
ISO Out : The host sends a command and receives data + the status words.

Coupler with firmware former than 40-017F has only ISO NONE, ISO IN and ISO OUT
protocol available.

In all cases, status words are returned (SW1 and SW2).
