4 TWN4 Palon One PCB
4.1 Functional Overview
The TWN4 Palon One is a complete RFID Reader system with a LEGIC HF frontend. It supports both
low (125kHz, 134.2kHz) and high (13.56MHz) frequency transponders. For operation, it requires a 5.0V
(via USB) or 9.0V - 30V (via connector X2) power source and connection to a host. The device can be
connected to the host via USB or RS485 (RS232 optionally) interface. The TWN4 Palon One also offers
a SAM slot and a speaker on board, as well as two RGB LEDs. For sabotage detection, the board is
equipped with a micro tamper switch (SW2). A DIP switch can be used to set the address for RS485
operation.
