BSM2-100 / 0533A03C-001 with 0001A04C and 0505A01A
REVISION 1.0, 2006-11-17
The BSM2-100 is a RFID Read-/Write-Device (short: reader) which is compatible to all
mifare® contactless smartcards. It provides a serial interface RS232 to output or exchange
data with a host computer and a 13.56MHz inductive interface to provide power to and
exchange data with the Mifare/ISO compliant card (or other available form-factors such as
tags, key-fobs).
Mounting and Connection
The reader generates a magnetic field with the frequency of 13.56MHz which is influenced by
any electrically conductive material in close proximity to the device. When mounting the
antenna, a distance to any such material of minimum 10 cm is required to ensure that there
will be no significant degradation of the performance in terms of read range and reliability.
Mounting the antenna directly to metal would result in a severe reduction of read range down
to zero functionality. Care should be taken when testing the device after mounting at a
problematic environment: Read ranges and performance vary from card to card and very
much between card and Tag’s or key-fob.
When mounting multiple readers, the distance between readers should be minimum 1 m to
avoid degradation of performance due to interference between the antennas.
To connect the device to a host computer, any serial RS232-interface (COM-port) can be
used. There is a special cable required to connect to the AMP MicroMatch 20-Pole connector
which provides the communication and power supply connections.
Operation
When the device is connected to a proper power supply, it will perform some initialization
routines and is then under control of the host system. The host software can initiate card scan
cycles and, after a card has been detected, perform read and write operations to the card
memory.
