Introduction

The ID ISC.LR2000 Long Range Reader and the ID ISC.LRM2000 Long Range Reader Unit are the

top of the line Long Range Reader versions of the OBID i-scan HF Product line. The OBID i-scan

HF product line offers a complete range of products to choose from to address the entire spectrum of

RFID data capture applications: from vicinity detection, to proximity and mid-range distances to the

absolute limits of HF detection.

The ID ISC.LR2000 and ID ISC.LRM2000 are the most powerful reader in the OBID i-scan HF prod-

uct line. Both devices have identical RF performance. The ID ISC.LRM2000 differs from the ID

ISC.LR2000 in terms of housing, interface options and functionality for the host connectivity of the

device.

Each member of the LR2000 product series have the following key RF features:

- Highly sensitivity receiver increased the tag detection range so that the most transponders can be

read over the entire power up, field strength area.

- RF front end accommodates arbitrary cable lengths between the reader and the antenna without

adversely affecting the read range of the antenna

- RF front end has its own power control to protect the read range from external noise sources.

- The reader delivers a DC voltage on the antenna output to source DC powered devices connected

to the antenna cable, such as the FEIG Dynamic Antenna Tuning board (ID ISC.ANT.DAT-A)

- RF source of the reader meets different national radio rules and can achieve the 60dbA/m ETSI

limits.

6. To comply with the radio approvals additional shielding may be needed

In addition to the ID ISC.LR2000 Reader series having the largest read range, the platform provides

the most extensive configuration possibilities and reader command set. The base set of commands

and features are compatible with the ISO Host commands used throughout the OBID i-scan product

line. The configuration possibilities of the ID ISC.LR2000 reader make it easy to adapt the reader to a

range of applications by software and hardware configuration.

The reader is able to directly control antenna multiplexing functions to handle complex antennas ar-

rayed in various gate and portal configurations. The reader is also able to directly control and monitor

the antenna tuning circuits of our Dynamic Tuning Board.

The RF section of the reader is controlled by a dedicated DSP based, RF controller. A second micro-

controller, the Application and Connectivity Controller (ACC), uses an ARM processor running a

µcLinux operating system. The ACC transforms the reader into a powerful and intelligent device, ca-

pable of running application software directly on the reader platform and capable of connecting and

controlling other real world devices. The reader has four hardware interface ports: Ethernet, RS232,

RS485, and a Compact Flash 2 compatible port to support a WLAN Card. All ports are under control

of the ACC. Furthermore, the reader i-

zation of the RF Process with nearby readers to avoid mutual interference.

In combination, the powerful and flexible RF transmitter and receiver and intelligent digital controller

form the basis of an agile, multi protocol reader that can be updated as future protocols and features

are created. The Reader supports the transponder protocols 18000-3-A. ISO15693 and HF EPC. The

ACC Firmware can also be updated allowing the reader to adapted to different applications. FEIG

Electronic provides a library which allows the user to develop their own applications to run on the

ACC.

Data Transmission between OBID i-scan® ID ISC.LR-Reader and Host

Five different ways of data transmission between OBID® i-scan Readers and host (terminal, PC) are

possible. The Host Commands, Buffered Read Mode and Notification Mode are used for the data

exchange between Transponder and host, whereas the Configuration Commands and the Reader

Control Commands serves for adapting the Reader parameters to the individual range of applica-

tions. The following chart shows which method of data transmission is supported by which interface:

Configuration Commands and Control Commands

This method of data transmission is used for Reader configuration and the diagnosis via the asyn-

chronous interface or Ethernet Interface

The Reader-configuration parameters will be stored in the Reader memory. To store the current con-

figuration during a power down of the Reader the Reader-Configuration has to be stored in the

EEPROM. After power up the Reader reads the configuration out of the EEPROM.

The Reader control is immediately processed and the response from the Reader contains status or

data information of the control command.

ISO15693 Host Commands

The ISO Host Commands provide the exchange of data between a host and Transponders via the

Reader as long as the Transponder remains in the detection range of the Reader.

Note:

During the writing of data on a Transponder, it must be ensured that the Transponder is lo-

cated within the detection range of the Reader during the entire process. If the Transponder

removed from detection range of the Reader during a writing process, this will cause a loss of

data.

The Reader distinguishes between three different modes:

Addressed mode:

Before reading or writing data in addressed mode, the UID of the Transponder has to be

7.1.1. [0x01] Inventory If a Transponder is

located within the detection range of the Reader at that time, it answers with its UID. For all

following read- / write orders the Transponder must be addressed with its correct UID.

is useful-, if only one Transponder is located within the range of the Reader.

Buffered Read Mode

The Buffered Read Mode is a high level operating mode to detect Transponders which are within the

detection range of the Reader. This operation mode is especially designed for applications which use

Transponders to identify objects. The Buffered Read Mode processes all Transponder read data and

filter operations to make the user interface transparent to Transponder data and to minimize data

transfers between Reader and host. There are only three commands used to control Buffered Read

Mode.

In this operating mode the Reader automatically selects Transponders which are within the detection

range of the Reader and reads their requested data. The read T

organized data buffer.

The sampled Transponder data can be read with the 8.3. Transponder Access in the Buffered Read

Mode and Notification Mode command. This command always reads the first available data sets from

the data buffer. However already read data has to be deleted with the 8.6. [0x32] Clear Data Buffer

command before the next data sets in the data buffer can be reached with the read command.

If the Buffered Read Mode is enabled in the 4.2. CFG1: Interface configuration block the Reader im-

mediately starts sampling Transponder data after power up. The Buffered Read Mode can be reinitia-

lized with the 8.7. [0x33] Initialize Buffer command.

If turned to Buffered Read Mode the Reader answers every valid message with data- or status-

protocol. The answer includes the control byte which has been received by the Reader.

Notification Mode

The Notification Mode is an extended option of the Buffered Read Mode: queued Transponder data

and optionally Input/Status events are notified automatically and asynchronously to a host with the

8.4. [0x22] Read Buffer response protocol. The destination address and the notification conditions

can be set in 4.31. CFG49: Notification Channel configuration block. In general, the notification

channel can be used simultaneously with the host interface.

In difference to the Buffered Read Mode procedure, a notification is normally not acknowledged by the

host. Thus, the deletion of the transferred data with the 8.6. [0x32] Clear Data Buffer command is

not necessary. As an option, this acknowledgement can be enabled to synchronize the notifications

with the host to prevent notification overflow in the host application.

The notification message format depends on trigger settings in 4.11. CFG10: Trigger and settings for

the read mode in 4.12. CFG11: Read Mode /Scan Mode – Read Data and 4.13. CFG12: Read

Mode - Filter as well as settings for the notification trigger in 4.31. CFG49: Notification Channel.

The following table lists the message formats:

Notification Trigger: continuous or time-triggered

Input/Status Event

Data Event

Read Trigger disabled

Input/Status and Data Events are notified together in one or multiple messages.

The message format depends on settings in TR-DATA of CFG11.

Read Trigger enabled

Notification separately and immediately,

if in:

CFG11: IN flag in TR-DATA2 is set

and

CFG12: flag is set for input and/or

status to be observed

NOTE: One notification can contain

more than one input/status event, if

multiple events occur at the same time.

Notification shortly after notification of

input/status event.

The message format depends on set-

tings in TR-DATA of CFG11.

Notification Trigger: host-triggered

Input/Status Event

Data Event

Independent of Read Trigger

Input/Status and Data Events are notified together in one message. The notifica-

tion is activated by command [0x34] Force Notify Trigger.

The message format depends on settings in TR-DATA of CFG11.

An additional option of the Notification Mode is the Keepalive message, which can be sent periodically

to the host. The Keepalive message transports valuable information about the reader hardware and

antenna tuning status. Keepalive messages are never acknowledged by the host. The Keepalive

message should not be mistake with the keepalive option (s. CFG41/CFG43) of a LAN/WLAN con-

nection initiated by a host.

Scan Mode

In this operation mode the Reader autonomously sends out data to the Host as soon as a Transpond-

er is within the detection range and valid data could be read.

In Scan Mode the contents of the message block (UID, data block) can be adapted to each user-

application. Scan mode is available via the asynchronous Interface.

The Reader starts the output of the protocol block as soon as all required data have been read cor-

rectly from the Transponder. If the Reader is not able to read all data of a protocol block completely

and without error, it does not send data. For example, if the address of the data block is invalid, the

UID of the Transponder will not be sent out.

Scan-Mode via asynchronous interface:

The data will be sent out depending on their configuration according to the following scheme,

the sequence of which cannot be changed.

Depending to the configuration and the number of Transponders in the detection range of the

Reader the transmitted protocols have a different format.

One Transponder in detection range and UID and data block should be read:

Reader Multiplex Mode (Syncronisation)

To enable more than one Reader to be used in close proximity, the RF operations executed by the

Readers must be multiplexed to prevent unwanted interference.

This is achieved by using the Multiplex (Sychronisation) Mode.

In combination with Buffered Read Mode the Multiplex Mode allows maximum speed of operation. In

this case each Reader passes control to the next after it has completed its task. This is effectively a

round-robin control, but it is much faster than single host control since it is controlled at a Reader lev-

el.

To setup the Multiplex (Sychronisation) Mode the Buffered Read Mode must be enabled in the 4.2.

CFG1: Interface and 4.12. CFG11: Read Mode /Scan Mode  Read Data configuration block and the

Multiplex Mode must be selected in the SYNC setting in the 4.19. CFG18: Reader Synchronisation

configuration block. The Reader that should trigger the multiplex chain must be configured as

MASTER in the SYNC setting in the 4.19. CFG18: Reader Synchronisation.

In the Multiplex Mode the signal input IN and the signal output OUT on connector X5 are used for

synchronization cable co
