1.1 General
This document provides information about the S6500 Long Range Reader Module.
It describes the reader and how to install it.
1.2 System Description
The HF Reader System Series 6000 works at a frequency of 13.56 MHz. It comprises
a reader, antenna and transponder (for example: smart label) and is used for wire-
less identification of a variety of objects.
The system works according the “reader talks first” principle which means that the
transponder keeps quiet until the reader sends a request to it. The reader can rapidly
and simultaneously identify numerous transponders in the antenna’s field. It can
write data to and read data from the transponders; either in addressed mode by using
the factory programmed read only number, or in general mode to all of the transpond-
ers in its field. The read/write capability of the transponder allows users to update the
data stored in the transponders memory anywhere along its movements.
1.3 Product Description
The S6500 Long Range Reader Module handles all RF and digital functions required
in order to communicate with Tag-it HF, Tag-it HF-I (ISO 15693 compliant) and all
other ISO 15693 compliant transponder from various suppliers.
The Reader Module is mounted onto a rigid, 6 mm thick aluminium base plate. The
module has two digital inputs, two digital outputs, a relay output and an asynchro-
nous interface which can be configured as RS232 or RS485.
The configurability of the interfaces also allows the module to be operated on an
RS485 data bus. The address can be assigned either through software or hardware
(3 DIP switches).
