1 Introduction Currently PORT Technology by Schindler supports a wide range of readers (C0…C10). In order to reduce the variety of card readers, we would like to introduce the TWN4 reader. The PCR-TWN4 is a LF Card Reader used in the PORT Technology devices (see table below). The HW is the same for both working frequencies and it is configured according the operation. The target devices for PCR-TWN4 are PORT1 and PORT4. Both devices have a metal housing that has an influence on the RFID readers.

Scope The PCR-TWN4 board implements the following main parts and functions: USB interface to host Radar interface (similar PCRI) I/O interface (similar PCRI): - 2 inputs - 2 outputs Wiegand Output (similar NFCUSB) 4 x RGB LED’s Compatibility The PCR-TWN4 is hardware compatible with PCRI resp. NFCUSB. Elevator Controller PORT USB Host LEP, MLEP, WLEP ... TWN4 PCR‐TWN4 + LF antenna General overview References REF[1] REF[2] REF[3] data sheet TWN4 reader module (www.elatec-rfid.

TWN4 module As a default the Mifare NFC Standard module should be applied. The main function of the TWN4 module is simply to manage the RF part of the PCR-TWN4. At the end is the interface between the RF part and the digital part.
PAGE 6
radio The RF frontend handles the transceiver functionality for contactless communication with a transponder at a frequency of 125 kHz with ASK, FSK or PSK. LF antenna Housing of PORT devices must be taken into account. Reading distance of min. 2 cm is requested, measured from the top of the housing.
