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.

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.
