REVISION 1.0, 2009-01-07
The Y591-EIND-101 is a RFID Read-/Write-Device (short: reader). The reader supports
Hitag© family tags and Indala cards. It provides a serial interface RS232 to output or
exchange data with a host computer (typically an Equitrac Page Counter Unit, a printer or a
copy machine) and a 125kHz inductive interface to supply power to and exchange data with
the tags. The host computer can control a bi-colour LED and a beeper to interface with the
user.
Mounting and Connection
The reader generates a magnetic field with the frequency of 125kHz which is influenced by
any electrically conductive material in close proximity to the device. When mounting the unit,
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 unit 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 from card
to tag or key-fob.
When mounting multiple readers, the distance between readers should be minimum 0.5 m in
order to avoid degradation of performance due to interference.
To connect the device to an Equitrac PageCounter, printer or copy machine, please make sure
the host system provides an 14-pin Mini-DIN socket intended for connection of the reader.
Operation
Whenever the device is connected to a proper power supply, it will switch on the internal
antenna and periodically scan for a card. Once a card has been detected, the card number is
read, the data converted and sent to the host system through the serial interface. To enable the
device to read cards, tags and key-fobs successfully, they should be placed centred above the
reader.
