1 Introduction
1 Introduction
TWN4 Palon is a family of innovative and configurable Reader/Writer for RFID transponders. This addition
to the popular TWN4 line of multi-standard RFID readers is ideally suited for integration into devices
and behind front panels. The module has both low (125kHz, 134.2kHz) and high (13.56MHz) frequency
antennas, allowing the user access to a wide range of RFID standards. With the support of NFC and BLE,
mobile phones can also be used for secure identification. A variety of interfaces are supported, including
USB, RS485, RS232, Wiegand and Clock/Data. An optional OSDP protocol is additionally available. Up
to five RGB LEDs can be freely programmed for optical signaling. Along with that, a SAM slot is provided
for applications with enhanced security requirements.
This technical handbook provides the details needed to get started using the TWN4 Palon - a functional
overview of the board, listing the features and interface options available.
A custom user app can be loaded onto the module using the AppBlaster software. For more information re-
garding the programming of the TWN4 module please see the dedicated User Guide for AppBlaster.

3 Software Requirement for Non-USB Communication
3 Software Requirement for Non-USB
Communication
If the TWN4 Palon is connected to RS232, RS485 or Wiegand / Clock & Data it is necessary to add the
following code to the TWN4 App.
const unsigned char AppManifest[] = { EXECUTE_APP, 1, EXECUTE_APP_ALWAYS, TLV_END };
This enables the App to start without USB enumeration.
To use the Host communication routines like HostWriteByte() with RS232 or RS485 connection, also add
following code to the TWN4 App.
SetHostChannel(CHANNEL_COM1);
A complete example of the TWN4 App is listed below.
#include "twn4.sys.h"
#include "apptools.h"
// necessary for Non-USB communication
const unsigned char AppManifest[] = { EXECUTE_APP, 1, EXECUTE_APP_ALWAYS, TLV_END };
int main(void)
{
SetHostChannel(CHANNEL_COM1); // necessary only for RS232 or RS485 communication
while (true)
{
// Do something
}
}

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.

4.3 DIP Switch and Main Connector
While the module can be connected via USB port, its main host connection is RS485. The RS485 interface
is accessable via X2. Table 4.1 shows the pinout of X2, figure 4.2 shows the polarity of the pins.
Pin Name
1 RS485_A
2 RS485_B
3 D0 or DATA
4 D1 or CLK
5 GND
6 UIN
Table 4.1: X2 Pinout
For RS485, the address of each module must be adjustable. This can be done with the DIP switches. Fur-
thermore, the RS485 bias and termination can be set. Table 4.2 shows the assignment of the DIP switches.
DIP Assignment
1 RS485 address 0 (LSB)
2 RS485 address 1
3 RS485 address 2
4 RS485 address 3 (MSB)
5 RS485 bias
6 RS485 baud rate (LSB)
7 RS485 baud rate (MSB)
8 RS485 Termination 120 Ohm
Table 4.2: DIP switches
The behaviour of the DIP switches 1-7 is controlled by firmware and may change in future.
When switch 5 / RS485 bias is switched on, a pull-up resistor is connected to RS485_A and a pull-down
resistor is connected to RS48_B signal. This prevents an undefined state of the bus when no transmitter
is active.
Switch 8 / RS485 Termination 120 Ohm connects a 120 Ohm resistor between RS485_A and RS485_B
signal, which prevents reflections on the bus.
