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.
