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. PORT1 PORT4 PORT Technology by Schindler Ltd - Oct 20, 2017 2 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 LEDs Compatibility The PCR-TWN4 is hardware compatible with PCRI resp. NFCUSB. Elevator Controller PORT USBHost LEP,MLEP,WLEP... TWN4 PCRTWN4

(optional) TWN4module HFantenna LFantenna Wiegand output IOs KLC1a radar interface JRC radar interface The PCR-TWN4 is composed of a main module (TWN4) that communicates through USB with a Host (main board inside the PORT Terminal). The TWN4 module is able to manage a variety of interfaces (RGB LEDs, IOs, proximity detection, status LEDs, ) and in the same time is also able to manage the reading of cards/tags through the HF and/or LF antenna. All the activities on the PCR-TWN4 are managed from the host processor inside the PORT Terminal. Functionality The main function of the PCR-TWN4 board is a RFID reader to be integrated into Schindlers PORT1 and PORT4 devices. The communication between the PCR-TWN4 and the host is made through the USB. USB and Power supply The main board power supply is U = 5 VDC 5% Imax = 500 mA from the Host. The USB communication is 2.0 Full-Speed (12Mbps). USB from the host is connected to the TWN4 board. Connector:

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. LF antenna implemented as an additional air coil and with the following features:
