3.2 General Description
Figure 1: L-L100 Packaged Reader
14/45 Revision 3.1b April 2003
Overview
3.2.1 RF Channels
The L-L100 Reader can drive up to two antennas with each channel able to drive up to four watts.
LEDs indicate which RF field (channel) is transmitting (green).
CAUTION: The antenna MUST be connected to the reader before the unit is turned on.
3.2.2 Synchronization Input/Output
When configured for input, this BNC connector makes it possible to use an external 27.12-MHz
clock to generate the RF field, instead of the internal clock generator.
When configured as output, this connector can drive other L-L100 readers and provide the
27.12-MHz clock.
The Sync LED indicates the clock mode:
• Red: The internal clock generator is enabled and an external clock signal cannot be input.
• Green: The internal clock generator is disabled. A 27.12-MHz clock signal must be
connected to the Sync In/Out connector.
By default, the internal clock mode is applied and the Sync In/Out connector is configured as an
output. If the external clock mode is required, contact your TAGSYS sales representative.
3.2.3 I/O Port Connector
The L-L100 reader provides four Input/Output (I/O) ports. Each I/O can be independently
configured as an input or output by the application software.
When configured as outputs, I/Os are open drain (250 mA). A pull-up supply must be connected to
the I/O port reference input (VIN). The pull-up supply voltage range is between 5V and 28V.
When configured as inputs, the I/O input signal range is between 0V and 28V.
I/O port LEDs indicate whether the I/O is configured for input (green) or output (red).
Please refer to Section 9, "I/O Ports" for more information.
Industrial I/O ports can only be accessed via the Data Processing Unit (DPU).
3.2.4 Init Button
The Init button aborts the embedded application stored in the Data Processing Unit memory. The
L-L100 Reader is then ready to be downloaded with a new application.
The L-L100 Reader must be switched off and then back on before an embedded application
takes effect.
April 2003 Revision 3.1b 15/45
Library L100 Reader User's Guide
3.2.5 Serial Connector
The serial connector is used to communicate with an external environment. User commands and
data exchanges are transmitted through this port which can be set to RS-232, RS-485 or RS-422
mode by the software. Different baud rates can be defined for each mode.
The Default Mode is defined by the application software which is downloaded in the L-L100
Reader.
Tx (Transmit data) and Rx (Receive Data) LEDs indicate the activity of the serial port.
The RS-232 cable is a null modem cable.
Please refer to Embedded Application chapter for further information about Application
Software.
3.2.6 Monitoring Port (Parallel Port)
The monitoring port communicates directly with the Radio Processing Unit (RPU). When the
parallel cable is plugged in, the Data Processing Unit (DPU) is automatically deselected. The
parallel port can be used as a monitoring tool or as a means to upgrade the L-L100 Reader
firmware via the L200 Explorer.
The parallel cable uses pin-to-pin DB25 connectors. A shielded cable must be used to
prevent disruptions when antennas have a high output power.
Please refer to L-L100 Reader Architecture chapter for further information about the RPU
and DPU. Please refer to “L-L100 Reader Firmware Reference” for further information about
L-L100 Reader Firmware.
3.2.7 Antennas
The L-L100 Reader is primarily designed for use with Aero-LI, L-SA1 and L-SA2 antennas.
Nonetheless, it is also operational with other TAGSYS antennas, provided that the power applied
to the antenna does not exceed antenna specifications. For more information, refer to Section 6,
"Antennas".
L-L100 Reader performance has been characterized for a 3-meter long antenna cable.
Optimized operation is not guaranteed with a cable longer than three meters.

HPI Interface
The RPU is managed by a Digital Signal Processor (DSP) which performs real-time chip decoding
and manages the reader configuration.
The RPU behaves as a slave as it waits for a host command, executes it and transmits the result.
This command exchange is performed using a specific protocol (HPI protocol) and a specific
interface (HPI interface). This protocol is based on the DSP dual-access memory. The host sends
commands to the DSP by writing to the DSP memory. It then reads the reply in the same memory.
The L-L100 Reader firmware is stored in DSP Flash memory. This firmware is TAGSYS property.
Please refer to “L-L100 Reader Firmware Reference “ for further information about L-L100 Reader
Firmware.
Two RF channels are available but only one can be read at a given time. The DSP controls an
analog switch and connects the RF channel to be read to the Analog/Digital Converter.
4.3 RF Channels and the Multiplexer Architecture
The antenna multiplexer and the RF channels belong to the RPU.
Two RF channels are available. These channels can be enabled independently
Each channel output power can be adjusted up to 4W. The same output level is applied to all the
enabled antennas.
Available phase shift values between antenna 1 and antenna 2 are 0°, 90° 180° and 270°.
On-Off Keying (OOK) and Amplitude Shift Keying (ASK) are available for reader-to-smart label
communication and are managed independently for each RF channel.

Depending on the software application downloaded into the GemCore Flash memory, it may be
possible to access all or part of the L-L100 Reader functions.
The STXE standard protocol application is delivered with the L-L100 Reader:
STXE Protocol is the TAGSYS standard protocol. It is compatible with most of TAGSYS
range reader products. We advise to use STXE protocol in order to address all TAGSYS
reader functions.

Antennas
6 Antennas
TAGSYS L-L100 readers are optimized for use with TAGSYS antennas.
The antennas are factory-calibrated to an impedance of 50 Ohms which offers optimal
performances when the antenna is mounted on a desktop surface.
Due to their specific design, these antennas can be safely used in proximity to other TAGSYS
RFID products. They will also work, if properly installed, in metallic-type environments. In this case,
performance may be reduced.
TAGSYS antennas are provided with rubber feet to operate in a standard desktop configuration.
However, a mounting kit is also supplied for installation underneath a table or desk.
Antennas are delivered with a standard plastic cover. This cover can be replaced by another made
of a non-metallic and non-conductive material. This cover should be as thin as possible as not to
impact the performance of the stack programming function. In addition, we strongly recommend
placing the antenna directly on the desk.
It may be necessary to retune the antenna once installed if the environment is highly metallic or if
the antenna is installed underneath a table or desk (and depending on the material of which the
desk/table is manufactured).
When installing a dual-antenna arrangement, a proximity effect may be created when using Aero LI
antennas. L-SA1 and L-SA2 are specifically designed to reduce this effect.

Read/antenna/ILS layout and maximum cable distances, to be specified.
7.2 Mechanical Aspects
The L-L100 Reader is delivered with four rubber pads screwed on the bottom of the package for
installation on a table or desk.
A mounting plate available with the L-L100 Reader can be used to mount the unit in various
positions. When mounted vertically, the BNC connectors must be facing upwards and
perpendicular to the floor.
When installing the L-L100 Reader on the mounting plate, remove the rubber pads from the L-L100
Reader and fasten the unit directly to the mounting plate.
CAUTION: The screws must be always attached to the bottom of the L-L100 Reader even if
the rubber pads and mounting plate are not used.

CAUTION: For continuous protection against risk of fire, use only T 2.5A – 250V rated fuses.
7.3 Cabling Requirements
All L-L100 Reader cables must be shielded. Shielding effectiveness of the material used should be
of Good performance (60dB min.), especially in the frequency range of 10 to 60 MHz. The addition
of ferrite clamps near the input/output will increase common mode rejection. TAGSYS antenna
products are delivered with good performance shielded coaxial cables with ferrite beads already
mounted to increase shielding effectiveness at low frequencies.

7.4 Operating Modes
The L-L100 Reader can be setup in one of two operating modes:
• Test/Setup mode used to test and develop your application,
• Main Operating mode for running your application.
CAUTION: The antenna MUST be connected to the reader unit before the reader is turned on.
7.4.1 Test/Setup Mode
The RPU host is connected to the L-L100 Reader by a parallel interface linking it to the monitoring
host, which is a computer. The L200 Explorer software is designed to set-up the L-L100 Reader
and to execute chip commands in a Windows environment.
This operating mode is useful to learn all L-L100 Reader basic functions and to rapidly start using
the packaged reader in a specific RFID application.
The L200 Explorer software is also a powerful and easy-to-use tool to define the best RFID set-up
for a custom application.
For additional information about the L200 Explorer software, refer to the L200 Explorer User’s
Guide.

In this mode, the L-L100 Reader is directly connected to the host PC via the DB25 parallel port
connector. Reader commands are only accessed using the L200 Explorer software.
1. Connect the antennas to the required inputs, according to application specifications.
2. Connect the L-L100 Reader monitoring port to the PC using the shielded parallel cable.

Installation
3. Connect the L-L100 Reader to the AC supply.
4. Start the L200 Explorer software application.
You can now configure the RPU of your L-L100 Reader as desired and start using most L-L100
Reader functions.
Test/Setup Mode is only available when using L200 Explorer Software. In this mode, certain
Data Processing Unit functions cannot be accessed.
7.4.2 Main Operating Mode
In Main Operating mode, the Data Processing Unit (DPU) is the RPU Host. The DPU can access
the DSP memory via the HPI interface.
When the L-L100 Reader Main Operating Mode is used, the DPU is the interface between the RPU
and the environment. In that case, the DPU can exchange data with a host system through the
embedded serial port interface.
When the Main operating mode is used, the host system is not connected to the RPU. In
other words, when the host system requires a command which must be executed by the RPU,
the GemCore OS receives this request and sends the corresponding command to the RPU.
The Main Operating mode is also designed for using the L-L100 Reader as a standalone device,
without a host.
Once the RFID system has been completely defined and it is ready for an industrial application, the
L-L100 Reader can be interfaced to specific network systems and various communication
protocols. This interface is implemented using custom DPU Application Software.
The command set and communication protocol between the DPU and the RPU are
completely defined by the DSP Firmware. It therefore cannot be customized.
On the other hand, the command set and the communication protocol between the DPU and
the L-L100 Reader Host are defined by the DPU application software. Developing new DPU
application software makes it possible to interface the L-L100 Reader with new environments
and to communicate using new protocols.

26/45 Revision 3.1b April 2003
Multiplexing Configuration
8 Multiplexing Configuration
The L-L100 Reader is designed with two transmit channels but with only one receive channel. This
means that each antenna can transmit an RF field used to read tags, but tag contents can only be
read by one antenna at a single time.
Tag reading performance can be enhanced by using the L-L100 Reader to perform read
operations on both antennas one after the other.
In addition, a phase shift can be applied between Antenna 1 and Antenna 2 for 3-D rotating field
applications.
These parameters are selected in Multiplexing mode which allows the user to completely define a
system based on its multiplexing configuration.
In particular, the following parameters are defined by the multiplexing mode:
• the transmitting antennas,
• the phase shift between the antennas,
• which antenna is read, and for how long.
8.1 Windows™ DLLs
The Library Windows™ DLLs automatically manage multiple-antenna applications for the L-L100
Reader.
The DLLs take advantage of multi-channel readers (L-L100 Library) for both reading and writing
using several specific functions. For more information, refer to the Library Windows™ DLL
Programming Guide.
8.2 STX-E Protocol
The STX-E Protocol can be used to develop dedicated application programs. For more information,
refer to the MedioSTX DLL Programming Guide.
Multiplexing information is organized into patterns. A sequence contains between one and eight
patterns that are applied one after the other in a loop. The L-L100 Reader can only store a single
sequence.
Figure 9: Sequence of Patterns in a Loop
Pattern 1 Pattern 2 Pattern 3 ...Pattern n
If n
p
atterns are defined
The multiplexing mode enables the user to implement several combinations on the basis of this
physical configuration. The following paragraphs provide implementation examples and show how
to choose the pattern.
8.3 Scanning (Reading)
The scanning parameters define which antenna is read (receives tag information), when it is read
and for how long.
April 2003 Revision 3.1b 27/45
Library L100 Reader User's Guide
For each pattern, the transmitting antennas will be read a set number of times. The number of
scans defines the global number of antenna read operations to be performed on each pattern. The
order in which antennas are read is always: Antenna 1 (if selected) and then Antenna 2 (if
selected).
The number of scans is common to all patterns, regardless of the number of antennas selected in
the pattern.
Each pattern is executed for the same length of time regardless of the number of antennas
selected in the pattern.
The duration of each scan period is defined as follows:
• For Reader Talks First (RTF) smart labels, the scanning duration gives the number of Read
commands sent to the tags during a single scan period. (Minimum Recommended Scan
Duration is 20 Read commands)
For RTF tags, L-L100 Reader must send a Read command to tag for it to be read.
• For Tag Talks First (TTF) smart labels, the scanning duration gives the time during which
the reading process is activated on one antenna during a single scan period. (Minimum
Recommended Scan Duration is 100 ms.)
When a TTF tag is detected, the read operation will be completed even if the scan duration
period has expired. In other words, the actual scan duration may be longer when a TTF tag is
processed at the end of the scan period.
For more information about Scan Number and Scan Duration parameters, refer to the example
given in Section 8.5.3, "Enabling each Antenna separately and then both at once".
8.4 3-D Rotating Field Applications
Phase shifts can be used to detect tags in a 3-D rotating field application. Phase shifts of 0°, 90°,
180° or 270° are available.
In this case, both antennas must be enabled (transmitting) simultaneously in order for the two
phases to create a 3-dimensional RF field.
8.5 Pattern Examples
8.5.1 Enabling one Antenna after Another
This is the most common example of a tag-reading pattern and requires the use of two patterns.
The first one enables only Antenna 1, while the second enables only Antenna 2.
In Pattern 1, Antenna 1 is enabled and then the detected tags are read. Afterwards in Pattern 2,
Antenna 1 is disabled, Antenna 2 is enabled and then the detected tags are read.
Channel 1 2
Pattern 1 Enabled Disabled
Pattern 2 Disabled Enabled
28/45 Revision 3.1b April 2003
Multiplexing Configuration
The advantage of this configuration is that the two antennas are not enabled at the same time,
reducing interference.
8.5.2 Enabling both Antennas Simultaneously
This configuration is implemented with only one pattern which enables Antennas 1 and 2 at the
same time. This configuration is best used for detecting smart labels in 3-dimensional rotating field
applications. For more information, refer to Section 8.4, "3-D Rotating Field Applications".
In this case, a phase shift should be applied to one of the antennas in order to create a 3-D RF
field.
Both Antennas 1 and 2 are enabled and the tags detected by Antenna 1 are read and then the
tags detected by Antenna 2 are read. (Only one channel can be read at a single time.)
Channel 1 2
Pattern 1 Enabled -Enabled
8.5.3 Enabling each Antenna separately and then both at once
Depending on the application requirements, in this configuration each antenna can be enabled
separately and then both at once.
In order to implement this configuration, three patterns are necessary. The first one enables only
Antenna 1, the second enables only Antenna 2 and the third enables both Antennas 1 and 2.
Channel 1 2
Pattern 1 Enabled Disabled
Pattern 2 Disabled Enabled
Pattern 3 Enabled -Enabled
In this example, the scanning parameters must be carefully selected. As both the Scan Number
and Scan Duration parameters are the same for all three patterns, if the Scan Number is set to 1,
Antenna 2 in Pattern 3 will not be read.
If the Scan Duration is set to 100 ms. and the Scan Number is set to 2, the tags detected by
Antenna 1 will be read twice (for 100 ms each time) in Pattern 1, then the tags detected by
Antenna 2 will be read twice (for 100 ms each time) in Pattern 2. In Pattern 3, the tags detected by
Antenna 1 will be read once for 100 ms. and then the tags detected by Antenna 2 will be read once
for 100 ms.
In the event that the Scan Number parameter is set to 3, the tags detected by Antennas 1 and 2
are read three times in Patterns 1 and 2, respectively. In Pattern 3, the tags detected by Antenna 1
are read once, then the tags detected by Antenna 2 are read once, and then the tags detected by
Antenna 1 are read a second time.
Each pattern will be executed for the same amount of time regardless of the number of
antennas selected in the pattern.
This duration is equal to the Scan Number x Scan Duration.

9 I/O Ports
The L-L100 Reader features four I/O ports. All four I/O ports can be configured independently as a
general purpose input or output.
Depending on the Application software downloaded in the DPU, the I/O port may command a
relay, trigger specific commands (Windowing…) or read input signals.
The I/O Port is controlled by the DPU with commands using STX protocol. This means that
I/Os are not controlled by the RPU which uses DLLs.
9.1 General Purpose I/Os
Each I/O can be configured independently as an input or output.
When an I/O is configured as input, it can be used to connect sensors or industrial logic commands
to execute a specific task. For instance, the L-L100 Reader can execute a smart label Read
command according to the logical level of the input command.
When the I/O is configured as output, it can command a relay or any other transducer.
• Input: Industrial logic (0V to 28V) TTL-compatible.
• Output: Open drain, 250 mA (maximum).
9.2 Internal Connections
This paragraph describes I/O electronic schematics when the configuration is set to input or output.
It also gives the characteristics of the VOUT supply which is available on the I/O port.

VOUT:

• Output current max: 100 mA
9.3 Input Configurations
When an I/O port is configured as an input, the external logic signal must be connected directly to
the input (0V-24V) of the requested I/O port. If the output of the external logic signal is an open-
collector output, the VIN signal must be connected to a supply (VOUT or external supply) or to the
ground to pull up/down the I/O port. In this case, all the grounds must be connected together
(external logic, external supply and L-L100 Reader ground supply). The following examples show
how to connect a signal (from a sensor, a push-button, etc…) to the L-L100 Reader.

9.4 Output Configurations
When an I/O port is configured as an output, the VIN signal must be connected to a supply to pull
up the I/O port when it is not activated. Setting the I/O port pulls down its output to the GND. VOUT
supply may be used to supply VIN signal and the external load. The following examples show how
to connect a load ( a relay, a light, etc.) to the L-L100 Reader using the internal supply (VOUT) or an
external supply.

10 Calibration
The L-L100 Reader features an innovative technology based on Digital Signal Processing (DSP) to
optimize long-distance reading and writing performances.
In particular, the L-L100 Reader is very efficient even in industrial and noisy environments.
Environmental conditions can vary significantly according to the application-specific factors such as
antenna size, output power, machines close to the L-L100 Reader, etc. Such parameters can
create noise around the RFID system.
In order to optimize the performance of your RFID system, it is possible to calibrate the L-L100
Reader. The calibration consists of selecting the best trigger threshold used to capture and decode
a smart label signal. The trigger threshold value corresponds to the sensitivity of the L-L100
Reader making it possible to differentiate a smart label signal from a noise signal.
If the trigger threshold value is too low, the L-L100 Reader may start decoding a signal which
actually is a noise signal. In this case, the decoding efficiency of the L-L100 Reader may decrease.
If the trigger threshold value is too high, the L-L100 Reader will not decode a low-magnitude smart
label signal (because it treats it as an ambient noise signal). In this case, reading distance
performance may decrease.
Ultimately, a compromise must be selected to find the best trigger threshold value.
The L200 Explorer application defines the optimized trigger threshold value. Please refer to the
L200 Explorer User’s Guide for further information.
Default trigger threshold values stored in the L-L100 Reader upon delivery depend on the smart
label type. These trigger values are optimized for Aero-LI, L-SA1 and L-SA2 antennas at middle-
range power.
The calibration process is only available for C210, C220 and C240 tag types.
CAUTION: C210 and C240 decoding algorithms have been modified to improve L-L100
Reader performances. It is possible that trigger values optimized for L-L100 Reader
Firmware releases previous to version 3.0 must be changed when using version 3.0 or more
recent.

11.1 Debugging Tools
The L-L100 Reader features debugging tools to optimize your RFID system installation and
communication with the tags.
Debugging tools can only be accessed with the L200 Explorer Software and consist of:
• A real-time oscilloscope to display the antenna signals received by the L-L100 Reader,
• A real-time frequency analyzer to display the frequency information of the Antennas signal,
• Some statistic information about the quality of your RFID System environment
