1. Introduction
The Compact Reader is a component of Hi-G-Tek’s wireless monitoring system use for
outdoor installations. It allows coverage and protection of secured cargoes or assets in
large storage yards and ports.
The Compact Reader utilizes RFID technology to communicate with the RFID sensors
(data tags /seals) over the UHF channel (433 MHz. or 916MHz). It interrogates their
ID, status and user data. Correspondingly, each tag/seal reports its unique identification
and anti-tamper alarm status in a short beacon transmission over the high-frequency
channel.
Each reader is able to communicate with a numerous sensors simultaneously, verifying
their presence and status, any changes in status are immediately reported. Using an
isolated RS-485 interface, multiple readers can be easily networked together into a
single controlling computer. This allows enlarging even further the coverage area of the
readers while keeping them synchronized within the field of application.
The Compact Reader powered from an indoor power supply & comm. unit (PSC unit)
that provides both protected power and isolated serial communication lines. Equipped
with RS-232 to RS-485 bi-directional serial communication converter, the PSC unit
easily forwards any RFID transaction from the Reader (RS-485) to the controlling
computer (RS-232) obtaining continually and real-time monitoring.
