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 target devices for PCR-TWN4 are PORT1 and PORT4. Both devices have a metal
housing that has an influence on the RFID readers.

Functionality
The main function of the PCR-TWN4 board is a RFID reader to be integrated into Schindler’s
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
communication is 2.0 Full-Speed (12Mbps). USB from the host is connected to the TWN4
board.
