S6500 Long Range Reader Module - Reference GuideMay ’01
This document provides information about the S6500 Long Range Reader Module.
It describes the reader and how to install it.
1.2System 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 wireless 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 transponders 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.
1.3Product 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 asynchronous 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).

3.1Introduction
Note:
Always ensure that the reader is switched off when making or breaking connections to it.
3.2General
The S6500 Reader Module has been designed with easy installation in mind. The following information provides you with any details that you will need to know.
3.2.1Default Configuration
The S6500 Reader is delivered with the default configuration as follows:
-Communication Interface: 38400 Baud,
8 data bits,
1 stop bit, even parity
-Antenna Connection: Only TX/RX Antenna active
-Anticollision procedure: active
-Supported Transponder Types: Tag-it HF,
Tag-it HF-I (and other ISO 15693 compliant
transponders)
However, if your system requires that you use the reader with a different configuration, you can use the S6 Reader Utility program which is available at our internet site
http://www.ti-rfid.com (S/W Tools & Download) to re-configure the reader to your sys-
tem’s requirements.
3.3Mechanical Mounting
Mounting is accomplished using the 4.5 mm diameter holes located in each corner
of the base plate (see Figure 3). If the antenna is properly tuned and there is sufficient
air convection along the mounting plate, the reader can be operated without an additional heat sink at up to 4 W of RF power.
If you are going to operate the reader module above 4 W (to fully exploit the reader’s
performance) it must be mounted on an additional heat sink. The heat sink should
have a thermal resistance R
Module to the heat sink you should strive for as little heat transfer resistance between
the base plate and the heat sink as possible. We recommend that you use a heat
sink compound.
Note:
If you are only using one transponder Type in the application, the
reaction time of the reader for transponder read/write operations can
be optimized as long as only one transponder driver (not both of
them) is activated.

Note:
Detuning of the antenna can result in additional heat being generated
in the reader. If this happens the reader regulates its output power
down until the final stage is once again within its upper temperature
limit.

3.4Connectors
3.4.1Power Supply Connector
The supply voltage is connected to connector X3 on the lower circuit board.
CAUTIONS:
1. Reversing the power supply wires may destroy the
device.
2. If you are using a switched power supply you must
ensure that the switching frequency is below 300 kHz.

!
Notes:
1. In order to conform to national requirements for radio devices, the
power supply line must incorporate one of the ∅ 28 mm x 20 mm
ring cores mentioned in section 1.5. The cable must be wound
around the core at least eight times (as shown in Figure 11). The
distance between the ring core and the reader connection must
not be more than 10 cm.
2. In order to avoid interference, the length of the cable between the
power supply and the reader must not exceed 3 m.
3.4.2Antenna Connectors (X1 & X2)
The transmit/receive antenna must be connected to the reader via the antenna SMA
socket (X2). The maximum tightening torque for the SMA socket is 0.45 Nm.
If you are using a receive only antenna (together with the read write antenna) it must
be connected to the reader via the antenna SMA socket (X1). The maximum tightening torque for the SMA socket is 0.45 Nm.
Notes:
1. In order to conform to national requirements for radio devices,
each antenna line must incorporate one of the ∅ 28 mm x 20 mm
ring cores mentioned in section 1.5. The cable must be wound
around the core at least four times (as shown in Figure 5). The
distance between the ring core and the reader connection must
not be more than 10 cm.
2. When connecting an antenna, ensure that it does not exceed the
permissible limits as prescribed by the national regulations for
radio frequency devices.

Figure 5: Antenna Line on a Ring Core
3.4.3Isolated Optocouplers Input Connector
The input LED's on the optocouplers have an internal input series resistor of 500 Ω.
For supply voltages above 10V the input current must be limited to a maximum of 20
mA by an additional external dropping resistor (see Figure 6 and Table 16).
CAUTION:
Reversing the polarity or overloading the inputs will
destroy the reader.
Notes:
1. If the connecting cable is longer than 3 m you must use a shielded
cable.
2. You must NOT use the reader’s supply voltage to drive these
inputs as the added noise may reduce the effective reading range.

3.4.4Isolated Optocoupler Outputs Connector
The transistor connections, collector and emitter, of the two optocoupler outputs are
galvanically isolated from the reader electronics and brought out on connector X6
without any additional circuitry. The outputs must therefore be powered by external
supplies.
The outputs are designed to switch resistive loads only.
Note:
If the connecting cable is longer than 3 m you must use shielded
cable.
CAUTIONS:
Reversing the power supply wires may destroy the device.

3.6Setting Bus Addresses
If you are going to use the reader connected to a bus you will have to give each reader an individual address. You can do that either by setting switch S2 on the reader or
by software from the controlling computer.
3.6.1Using S2 to Set the Address
You can use switch S2 to set the reader address between “0" and “7".
To set the bus address using S2, the Reader must be set to software address “0"
(factory setting).

5.1Regulatory Notes
An RFID system comprises an RF transmission device, and is therefore subject to
national and international regulations.
Prior to operating the S6500 Long Range Reader Module together with antenna(s)
and power supply, the required FCC, PTT or relevant government agency approval
must be obtained. Sale, lease or operation in some countries may be subject to prior
approval by the government or other organization.
5.1.1FCC Notices (U.S.A.)
A typical system configuration containing the S6500 Long Range Reader Module has
been tested and found to comply with the limits for a Class A digital device, pursuant
to Part 15 of the FCC Rules. It is the responsibility of the system integrators to get
their complete system tested and to obtain approvals from the appropriate local authorities before operating or selling this system.
5.1.2R&TTE Conformity (Europe)
A R&TTE Declaration of Conformity is available for the S6500 Long Range Reader
Module at TI*RFID Sales Offices.
The equipment complies with the essential requirements of the Telecommunication
Terminal Equipment Act (FTEG) and the R&TTE Directive 1999/5/EC when used for
its intended purpose.
Any device or system incorporating the S6500 Long Range Reader Module in any
other than the originally tested configuration needs to be verified against the requirements of the Telecommunication Terminal Equipment Act (FTEG) and the R&TTE
Directive 1999/5/EC. A separate Declaration of Conformity must be issued by the
System Integrator or user of such a system prior to marketing and operating it in European Community.
It is the responsibility of the system integrators to get their complete system tested
and to obtain approvals from the appropriate local authorities before operating or
selling the system.
