1. Introduction
1.1. The OBID i-scan®ID ISC.LR Reader
The ID ISC.LR Products are the Long Range Readers of the OBID®i-scan Product line. The whole
OBID®i-scan product line covers the entire spectrum of reading distances from short range, proximity,
mid-range to long-range devices.
The Readers differ in the shape of the housing, the place of installation of the antennas and the
maximum write-/ reading distance. The Reader product-family consists of types without housing which
are to be installed into already existing devices, of types with housing for hand-held and of types which
are suitable for mounting on, for example, conveyors.
A mixed function of different OBID®i-scan Reader types within the same installation is possible by
means of a uniform communication interface. Each Reader is equipped with a bi-directional,
asynchronous interface (RS232, RS485).
Another advantage is the multi-tag feature. This means that the Readers are able to read and write on
different Transponder types.
The ID ISC.LR Readers are the most powerful Readers in the OBID®i-scan product line. The ID
ISC.LR Readers are have the largest read range, greatest configuration possibilities and most Reader
commands. The base set of commands and features is fully compatible to the commands of the other
OBID®i-scan product line members. The configuration possibilities of the ID LR.ISC Readers makes it
easy to adapt them to the individual range of applications by soft- and hardware configuration.

2. 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 2.2. ISO15693 Host Commands, the 2.3. Buffered Read Mode, the 2.4. Scan Mode for
the data exchange between Transponder and host, whereas the 2.1. Configuration Commands, Control
Commands serves for adapting the Reader parameters to the individual range of applications. The
following chart shows which method of data transmission is supported by which interface:
asynchronous interface
(RS232 / RS485)
Configuration Commands √
Reader Control Commands √
ISO15693 Host Commands √
Buffered Read Mode √
Scan Mode √
2.1. Configuration Commands, Control Commands
This method of data transmission is used for Reader configuration, the Reader diagnostics via the
asynchronous interface.
The Reader-configuration parameters will be stored in the Reader memory. To store the current
configuration 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 command.

2.2. ISO15693 Host Commands
The ISO15693 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 located
within the detection range of the Reader during the entire process. If the Transponder is
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
known. This is executed by sending the protocol “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.
The following chart will show the necessary steps for the communication with a Transponder in
addressed mode:
Host (Terminal / PC / ....) Reader

Yes No
←status /

Transponders /

←

FEIG ELECTRONIC GmbH Page 15 of 174 H90692-16e-ID-B.doc
Non-addressed mode:
In non-addressed mode, it is not necessary to know the UID of the Transponder. This mode is
useful if only one Transponder is located within the range of the Reader.
The following chart will show the necessary steps for the communication with a Transponder in
non-addressed mode:
Host (Terminal / PC / ....) Reader

Yes No

FEIG ELECTRONIC GmbH Page 16 of 174 H90692-16e-ID-B.doc
Selected:
In this mode the Reader communicates only with the one, selected Transponder.
Before reading or writing data in selected mode, the UID of the Transponder has to be known.
This is executed by sending at first the protocol “7.1.1. [0x01] Inventory“. In a second step the
Transponder must be selected with the select command (see: 7.1.6. [0x25] Select) which must
include its UID.
The following chart will show the necessary steps for the communication with a Transponder in
selected mode:

2.3. 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 Transponder data is stored in a ‘FIFO’
organized data buffer.
The sampled Transponder data can be read with the 8.3. [0x21] Read Buffer command. This
command always reads the first available data sets from the data buffer. However already read data
has to be deleted with the 8.5. [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 3.10. CFG10: General System Parameters configuration
block the Reader immediately starts sampling Transponder data after power up. The Buffered Read
Mode can be reinitialized with the 8.6. [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.

2.4. Scan Mode
In this operation mode the Reader autonomously sends out data to the Host as soon as a Transponder
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
correctly 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 send 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.
Example 1:
One Transponder in detection range and UID and data block should be read:
PRUIDSCdataEC PRUID
Example 2:
3 Transponder in detection range only UID should be read:
PR UID1 EC UID2 EC UID3 EC
Example 3:
3 Transponder in detection range only data block should be read:
PR data1 EC data2 EC data3 EC
Example 4:
2 Transponder in detection range UID and data block should be read:
PR UID1 SC data1 EC UID2 SC data2 EC
PR: Com-Prefix (optional) ts: SCAN-LOCK-TIME
UID: Serial-Number (fix) tr: time to the next new Transponder reading
data: data blocks (free programmable)
SC Separation character (optional)
EC End character (optional)

Note:
•If configuration protocols shall be sent to the Reader while the Scan Mode is active, no
Transponder should be within the detection range of the Reader during this time.
•Only read operations are available with the Scan Mode.
•Scan Mode is only available if Buffered Read Mode is disabled
•The Scan Mode can be used with the 2.5. Reader Multiplex Mode.

2.5. Reader Multiplex Mode
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 be achieved by using the Multiplex 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 level.
To setup the Multiplex Mode the Buffered Read Mode must be enabled in the 3.10. CFG10: General
System Parameters configuration block and the Multiplex Mode must be selected in the SYNC setting
in the 3.11. CFG11: Buffered Read Mode configuration block. The Reader that should trigger the
multiplex chain must be configured as MASTER in the SYNC setting in the 3.11. CFG11: Buffered
Read Mode configuration block.
In the Multiplex Mode the signal input IN1 and the signal output OUT1 are reserved for synchronization
cable connections. Please note that the signal input and the signal output are isolated and must be
supplied with external DC voltage. Please refer the manual “Mounting Instructions ID ISCLR200.x-x”
(M00601-xde-ID-B / M00602-xde-ID-B) for details.
Note:
Multiplex Mode will only be available in Buffered Read Mode.
