1. Introduction
1.1. Principles of operation of the OBID®-System
The OBID® Identification System is an inductive transmission system for non-contact identification
(ID) of objects. Use of the components in the read/write system makes it possible to read and write
passive transponders. This system consists of a reader, antenna and a transponder as storage
medium for the data.
When a transponder enters the local magnetic field of the antenna, it is supplied with energy and can
be written to or read. The received data are received by the same reader antenna which generates the
magnetic field and sends the data to the transponder.
The magnetic field and the send and received transponder data can penetrate all non-conducting
materials, so that even hidden reading and writing is possible.
1.2. The OBID®ID RW01L.AB-A
The OBID®ID RW01L.AB-A reader is designed for typical applications involving personnel
identification, access control, time tracking, billing systems, etc.
It features multi-tag capability. This means it can:
•read read-only data carriers (OBID®ID CTx.A)
e.g. H4001, H4002, H4022, H4102, etc. from EM Microelectronics and
Unique from SOKYMAT as well as
•read/write transponders (OBID®ID DTx.B)
HITAG 1 and HITAG S from Philips Semiconductors.
The reader has a bi-directional, asynchronous interface (RS232-TTL) and a unidirectional data/clock
interface which can run in Wiegand or magnetic card reader emulation. The emulation modes of the
data/clock interface ensures easy conversion from traditional identification readers to the OBID®ID
RW01L.AB-A.
The OBID®ID RW01L.AB-A can be easily software-configured for any application.
The OBID®ID RW01L.AB-A offers access to the entire physical memory range of the supported
transponders (see: 3.2. [0x14] WRITE_DB (Write data block(s)) / 3.3. [0x15] READ_DB (Read data

There are two ways to toggle between polling and scan mode.
•By soldering a 0 Ωresistor in B1 (see: 1.3. Technical data) scan mode is permanently activated.
•To temporarily activate scan mode, you can tie input MOD1 to potential GND (X2 / Pin 3).

1.7. Connecting an external antenna
In place of the antenna on the ID RW01L.AB-A, you may connect an external antenna to terminals
ANT1 and ANT2 (X1). When connecting an external antenna, you must separate the two connections
on the onboard antenna.
Note the following when dimensioning and tuning the antenna.
Antenna parameters
- Recommended max. dimensions 70 x 70 mm
- Antenna coil material : Lacquered copper wire
- Antenna coil wire thickness: 0.2 mm
- Inductance: 737 ±7 µH
- Resistance: 10 ±1 Ω
- Intrinsic capacitance < 120 pF

NOTE:
The reader is designed for operating only one antenna. Operating 2 parallel switched antennas
may damage the reader, or at least have a negative impact on the read range of the reader.

2. Data traffic between Reader and Host
There are three different kinds of data traffic between the reader and a host (terminal, PC, etc.).
Polling and scan modes are used for data exchange between the transponder and host, whereas
configuration mode is used to configure the reader parameters to the particular application. Which kind
of data traffic is supported by which interface is shown in the table below.
Asynchronous interface
(RS232-TTL)

NOTES:
•A hardware solution is used for toggling between polling and scan mode (see: 1.6. Toggling
Polling- / Scan-Mode)
•When scan mode is active, neither polling nor configuration mode is allowed!

OBID®Manual ID RW01L.AB-A
FEIG ELECTRONIC GmbH Page 12 of 39 H20801-1e-ID-B.doc
2.1. Asynchronous interface, data formats and protocol frames
The asynchronous interface can be used to configure the ID RW01L.AB-A, write data to the
transponder and read data from the transponder. Communication between reader and host (terminal,
PC, etc.) takes place using fixed protocols. The protocol used is designed for data bus exchange and
includes a bus address.
In data traffic over the asynchronous interface the reader replies with the requested data and a status
message. The reply always includes the sent control byte.
Protocol structure:
Host →Reader:
1 2 3 4...n-1 n
Length = n COM-Adr Control byte Protocol data CSUM
Host ←Reader
1 2 3 4 (5...n-1) n
Length = n COM-Adr Control byte Status1(protocol data) CSUM
Length n:
Number of protocol bytes 1- n incl. length byte and checksum
COM-Adr:
0..7 Device address for bus operation
NOTE(S):
The reader can always be accessed at COM-Adr = 255.
Status / protocol data:
Contains the status message or protocol data to or from reader
CSUM: XOR operation of the protocol byte from 1 to n-1

2.2. Polling mode
In polling mode you can exchange data between the host and a transponder via the reader in any
sequence and as often as desired as long as the transponder is in the detection zone of the reader
and the host has “selected” the transponder. Scan mode must be inactive in order to exchange data in
polling mode.
Before reading or writing any data, a transponder must be selected. In addition you must use the
protocol for reading the serial no. (see: 3.1. [0x11] GET_SNR). If at this time a transponder is located
in the detection zone of the reader, the former is selected and all following read/write commands affect
this transponder only.
Required steps for communication with a transponder in polling mode:
1. Select transponder (Protocol: Read serial no.)
2. Send any command to transponder
Host (Terminal / PC / ....) Reader (Reader)
Select transponder →Transponder in field ?
(read serial no.) Yes No
←Transponder type
and serial no. Status = no transponder
←
Read data →Selected transponder in field ?
Yes No
←Status / data
protocol Status = no transponder
selected
←
Write data →Selected transponder in field ?
Yes No
←Status protocol Status = no
transponder
selected
←
NOTE(S):
While writing data to a transponder, be sure that it remains in the read range for the entire
duration of the write procedure. If the transponder is removed from the detection zone during a
write procedure, you may lose data.

OBID®Manual ID RW01L.AB-A
FEIG ELECTRONIC GmbH Page 15 of 39 H20801-1e-ID-B.doc
2.3. Scan mode
In this mode the reader autonomously sends data to the host as soon as a transponder is located in its
detection zone and it has read the required data. Scan mode can be configured within a broad scope,
so that it can be adapted to virtually any application.
In scan mode the data are generally output one time. Only when the transponder has left the detection
zone for time SCAN_LOCK_TIME (see: 5.1.3. SCAN_MODE) are the data output again.
In scan mode you can read and output either the serial number or a data block from a transponder.
The data format depends on the selected interface (asynchronous or data/clock interface).

OBID®Manual ID RW01L.AB-A
FEIG ELECTRONIC GmbH Page 16 of 39 H20801-1e-ID-B.doc
2.3.1. Scan mode over the asynchronous interface
If scan mode is used over the asynchronous interface, the transponder data are output either in hex
format or in ASCII format (see: 5.1.3. SCAN_MODE). In addition, it is possible to preface an individual
start character (SCAN_PREFIX) and/or append a terminating character (SCAN_TERM).
The following examples show how 5 bytes of raw transponder data can be output over the serial
interface for various configurations:

2.3.2. Scan mode over the data/clock interface
In addition to the asynchronous interface, a synchronous data/clock interface is available which works
unidirectional in either Wiegand or magnetic card emulation. The serial number or data can be output
on this interface. The data/clock interfaces can be used only in scan mode.
2.3.2.1. Magnetic card emulation
Data format:
Magnetic card emulation offers three various data formats for data output. These formats are
shown in the following table and are configured using parameter 5.1.2. READER_MODE.
The data volume can be defined using parameter 5.1.5. D_LGT and 5.1.6. D_START.
