Manual ID RW01L.AB-A

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
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
RW01L.AB-A.

The OBID

®

ID RW01L.AB-A can be easily software-configured for any application.

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

1.6. Toggling Polling- / Scan-Mode

There are two ways to toggle between polling and scan mode.

• By soldering a 0 Ω resistor 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).

The following table shows the possible configurations.

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

f: 125 kHz

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.

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

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:
