Operation Manual
0052A02B-002 / ACCESS45-5-232-LB-EQUITRAC
REVISION 1.0, 2006-08-06
The ACCESS45-5-232-M1415-LB is a RFID Read-/Write-Device (short: reader) which is
compatible to all Mifare cards. The reader also supports ISO14443A/B and ISO15693 and all
cards compliant to these standards. 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 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). 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 13.56MHz 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 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 8-pin Mini-DIN socket intended for connection of the reader.
Alternatively, the reader can be connected to any serial RS232-interface by using a converter
connector from 8-pin Mini-DIN female to D-Sub 9 female and suitable connection for a
power supply. In case the LED and Beeper control lines should be operated, suitable control
can be applied according to the below given specifications.
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.

Serial Interface
The TXD/RXD signals are compatible with RS-232 level signals. The interface
operates at 2400 baud, no parity, 8 data bits, 1 stop bit. Upon detection of a valid
card swipe, the reader outputs the card number in ASCII format.

FCC
Any changes or modifications not expressly approved by the party responsible for
compliance could void the user's authority to operate the equipment.
To comply with FCC emission limits a ferrite core is supplied with the unit to be attached
close to the dc connector as described in figures 1 and 2. Attaching the ferrite core is
essential for the user's authority to operate the equipment.
Figure 1 shows the ferrite core open with two-turn coiling of the dc supply lines (one turn
means putting the lines straight into the ferrite, two turns means one additional loop). After
that the ferrite has to be closed. A click indicates proper locking. Figure 2 shows the closed
ferrite core attached to the dc supply lines.
