Introduction
The PCR2-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.
PCR2-TWN4 is the successor of PCR-TWN4 resp. PCR-TWN4-mini adapted to the next
generation PORT design. The major difference is the arrangement of camera and RFID
reader within the fancy RGB LED circle.
The target devices for PCR2-TWN4 are:
PORT1
PORT4
PORT5
1.1
The PCR2-TWN4 board implements the following main parts and functions:
1.2
The PCR2-TWN4 is hardware compatible with the PCR2 PCB and software compatible with
PCR-TWN4 resp. PCR-TWN4-mini.

General board implementation
Block Schematic
The PCR2-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 PCR2-TWN4 are managed from the host processor inside the PORT Terminal.

As a standard, NJR radar is connected. However, with an extension board (analog filter) it is also
possible to connect a radar by RF Beam.
