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.
TheSLRM900isdesignedtoaccessalltypesoflabelsand
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.
