1 Introduction
CurrentlyPORT Technology by Schindler supports a wide rangeof readers (C0…C10).In
order to reduce the varietyof card readers, we would like to introduce the TWN4 reader.
The target devices for PCR-TWN4 are PORT1 and PORT4. Both devices have a metal
housing that has an influence on the RFID readers.

2 General board implementation
Block schematic
Functionality
The main function of the PCR-TWN4 board is a RFID readerto be integrated into Schindler’s
PORT1 and PORT4 devices. The communication between the PCR-TWN4 and the host is
made through theUSB.
USB and Power supply
The main board power supply is U = 5 V DC ± 5% Imax = 500 mA from the Host The USB
communication is 2.0 Full-Speed (12Mbps). USBfrom the hostis connected to the TWN4
board.

radio
The RF frontend handles the transceiver functionality for contactless communication with a
transponder at a frequency of 13.56 MHz with ASK.
HF 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.
HF antenna integrated into the PCB with the following features:
