GENERAL DESCRIPTION

Generally, the SLRM900 can communicate with smart
labels based on Philips I-CODE1 label IC SL1ICS3001.
It consists of a 2-way communication transmitter and
receiver, for generating, transmitting, receiving, and
processing identification signals.

Optional input and output ports, and an RS232 interface
offer the possibility to connect the unit to a microcontroller
or PC.

The SLRM900 is designed to access all types of labels and
transponders that are based on the I-CODE1 label IC.
Read and write functionality is included, as well as
sophisticated ways to use the anticollision capability of
I-CODE.

High emphasis is put on long range functionality, which
makes the SLRM900 suitable for gate antennas and
tunnel reader applications. In order to provide the
appropriate output power level for various types of
connected antennas, the output power may be adjusted,
using simple software configuration commands.

Many reference installations with high demands on
anticollision, reading range, and data reliability in noisy
environments, have proven the capability of both the
reader module and the I-CODE1 label IC.

This document describes the reader hardware, interface,
and connection of the antenna.

Fig.6 System overview.

7.1

System overview

The SLRM900 is part of a complete Radio Frequency
Identification (RFID) system (see Fig.6).

The SLRM900 can communicate with I-CODE smart
labels. The device consists of a two-way communication
transmitter and receiver, for generating, transmitting,
receiving, and processing identification signals.

In the transmit mode, the microcontroller board generates
data whereas the RF board uses this signal to modulate a
carrier. This modulated carrier will be amplified, and
transmitted by the antenna to the label. This label will
subsequently generate its response, which will be
picked-up by the SLRM900 in the receive mode, and
processed by the digital hardware.

By using the RS232 serial interface (or the optional input
and output ports) the output parameters of the module can
be set.

7.1.1

I-CODE labels

The SLRM900 is designed for communication with smart
labels based on Philips I-CODE1 label IC SL1ICS3001.

7.1.2

OST

The connection to the host (e.g. microcontroller or PC) is a
serial interface on RS232 level for data transmission. For
the protocol please refer to data sheet

"SLRM900 I-CODE

Long Range Reader Module, protocol Reader-Host".

7.1.3

I/O

PORTS

There are 6 input ports, 4 output ports, and one EAS
signal output port available on the microcontroller board
(see Section 6.5). These ports are software
programmable. The input and output ports are not lead out
of the metal housing and therefore not ESD protected.

7.1.4

NTENNA

A 50

antenna has to be connected to the antenna

connector. This antenna has to be designed according to
application note

"I-CODE design of Read/Write antennas".

7.1.5

OWER SUPPLY

To work with the SLRM900, an external linear regulated
power supply has to be used. Using the supplied power
supply cable is recommended, in order to comply with the
EMC and EMI limits (see Section 7.5).

The reader module contains filtering circuitries for the
power supply. However, some requirements are to be
fulfilled by the power supply. The maximum ripple of the
supply voltage must not exceed the maximum values
specified in Table 2.

Reader software

The available software for the SLRM900 is contained in
document

"SLRM900 I-CODE Long Range Reader

Module, protocol Reader-Host".

7.3

Reader hardware

The internal electronics of the SLRM900 can be divided in
two major units:

RF board (see Fig.7)

Microcontroller board (see Fig.8).

7.3.1

BOARD

7.3.1.1

Voltage regulation

All necessary internal voltages for the module are derived
internally from the 24 V DC power supply voltage.

7.3.1.2

Clock generator

This part generates the 13.56 MHz clock frequency for the
transmitter amplifier. A divided clock signal is connected to
the microcontroller for synchronization purposes.

7.3.1.3

Modulator and transmitter amplifier

To transmit data to the I-CODE labels, the carrier has to be
modulated by the modulator with a digital signal from the
microcontroller according to data sheet

"SL1ICS3001

I-CODE Label IC, protocol air interface". The transmitter
amplifier amplifies the modulated carrier signal.

7.3.1.4

Modulation index and RF power regulation

The RF power regulator keeps the antenna output voltage
to a level determined by software settings. Also, by using
software settings, the modulation index can be set,
according to data sheet

"SL1ICS3001 I-CODE Label IC".

The required modulation index has to be re-adjusted after
any change of the RF output power and at large
temperature variations.

7.3.1.5

Receiver, filter, demodulator, and ADC

An amplitude modulated signal is received from the
I-CODE1 label IC. After filtering, demodulation, and
amplification, the analog data signal is converted by the
12-bit ADC for further digital processing.

7.3.1.6

Opto-couplers

All internal analog and digital signals between the
RF board and microcontroller board are galvanically
separated by opto-couplers.

7.3.2

ICROCONTROLLER BOARD

7.3.2.1

Microcontroller

The microcontroller processes the protocol for the
communication between the I-CODE labels and the
SLRM900. The serial interface signals are converted in
such a way, that the labels are able to process them, and
the outgoing signals from the labels are converted into
serial interface-compatible signals.

Another important microcontroller task is its control
function. Software control offers the possibility to change
both the RF-output power and the modulation index.

7.3.2.2

RS232 interface

The device communicates with the host (processor or PC)
via a serial interface, using a jumper-selectable baud rate
of either 57.6 kbaud in standard mode, or 115.2 kbaud in
fast mode (see setting for JP4 in Table 3).

7.5

EMC and EMI

The SLRM900 is designed in such a way that it is possible
to build systems with it, which are in conformance with
EMC and EMI standards.

Electromagnetic emissions comply with the guidelines in
BAPT 222 ZV 122 and EN 300 330. Electromagnetic
immunity complies with the guidelines in ETS 300 683.

The conformance to EMC and EMI standards can only be
granted for systems, not for components.

The following measurements have been passed:

EMI: EN 300 330, BAPT 222 ZV 122, FCC 47 part 15

Immunity: ETS 300 683.

The following configuration is in compliance with the
telecommunication standards:

SLRM900: output power 4 W at 50

; modulation index

m = 15%; standard mode

Linear power supply (according to the recommendations
in Table 1), connected via the supplied power supply
cable

according to application note

"I-CODE, Design of

7.6

Safety and reliability considerations

The SLRM900 has implemented measures for high
reliability.

7.6.1

NTENNA RUPTURE AND ANTENNA SHORT

CIRCUIT

The SLRM900 does not immediately get damaged in case
of either an antenna short-circuit, or an antenna rupture
with short duration. However, permanent antenna
short-circuit, or antenna rupture, will definitely damage the
SLRM900. The supply current of the SLRM900 will be
limited at typical 1.6 A.

7.6.2

UPPLY VOLTAGE

The SLRM900 is protected against short supply voltage
peaks and incorrect polarity for a short time, but
permanent incorrect supply will definitely damage the
device.
