1. Introduction
1. Introduction
The TWN4 MultiTech Nano Module is a configurable Reader/Writer of RFID transponders. It provides ports
that can be connected to antennas operating at low (125kHz, 134.2kHz) and high (13.56MHz) frequencies.
The Module can be accessed via a set of interfaces including USB, I2C, SPI, SAM, CAN, GPIO and COM
(x2). The Nano device leaves to the User the implementation of the circuits required for full I/O and
antenna functionality. As a result, the Nano boasts the smallest footprint within the TWN4 family, while
affording the User the maximum flexibility in terms of Peripheral and Interface selection as well as Antenna
properties.
This Development Kit is a vehicle intended to support the User with the integration of the Nano Module
into their Product and the development of the required software. The Kit contains the fundamental func-
tionalities needed to develop a working RFID Reader prototype.
Package Contents:
• Development board
• TWN4 MultiTech Nano Module

2. Getting Started
2. Getting Started
2.1. Functional Overview
The functional layout of the Development Board is shown on Figure 2.1. Main features of the Development
Board are:
• Ready-to-Use primary interfaces to the USB (8-pin DF11 or Micro USB) and UART (DF11) ports
• 2 SAM card slots.
• General COM2 port that can be configured for a custom application
• impedance-matched LF and RF antennas
• speaker
• 4 configurable LEDs
The Board also offers a breakout connector (Expansion slot) for the entire Nano Module pinout. This extra
interface allows for live monitoring of the signals going to/from the Nano Module. The breakout connector
can also be used with the I/O Extender Module documented separately. The I/O Extender provides extra
debug functionality, an LCD screen and a number of serial interface adapters for the COM2 port.

2. Getting Started
2.2. Replacing the Nano Module
Please use the set of Levers provided with the package to replace the Nano Module on the Develop-
ment board. Place the levers on both sides of the Nano Module as shown on Figure 2.2. Gently and
simultaneously push them down to extract the Nano Module from the board.
Figure 2.2.: Nano Module extraction levers
When inserting the Nano Module into the Development Board, please observe the correct polarity of the
Module. The connector marking for Pin 1 (white dot) should be aligned with the small indentation on the
Nano Module.
Warning: inserting the Nano Module into the board with incorrect polarity can cause permanent
damage to the Module!
2.3. Establishing Connection
The Development Board can be connected to via USB (DF11 or Micro USB) or RS232 (DF11) port. In the
case of the RS232 port, a DC Power Source of 5V has to be provided. In order to start operating the TWN4
MultiTech Nano (LEGIC 42), simply connect the desired port to the Host. The settings of the "COM1 &
Power-On" DIP Switch (see Figure 2.1) need to be adjusted depending on connection type. Please see
Table 2.1 for details.
Connector Instructions
USB 1) On Development Board, plug in broken-out USB cable to the appropriate pins of DF11
connector; alternatively use Micro USB connector. Connect other side of cable to a PC.
2) "COM1 & Power-On" DIP Switch: Bit 3=ON
You can still use COM1 or RS232 ports. See Table 3.1 for instructions.
RS232 1) Plug in the DF11 connector of the RS232 cable to the appropriate connector of the
development board and the D-Sub 9 connector to a PC. Plug in a suitable power adapter
to the DC jack of the D-Sub connector.
2) "COM1 & Power-On" DIP Switch bits: 1=ON, 2=ON, 3=ON, 4=ON
Table 2.1.: Establishing Connection
Once the board is connected to a host, a driver must be installed (in case of USB connection). Therefore
install the driver included in TWN4 DevPack. When driver installation is finished, a new virtual COM port
is available on the PC. Now you can set up a connection to the TWN4 MultiTech Nano using this COM
port.

2.4. Flashing Firmware and Application Code
TWN4 MultiTech Development Pack contains ready-to-use Firmware images that can be programmed into
the Nano Module using the AppBlaster program (present within the same Development Pack). Generic
Firmware used to identify most RFID cards can be found at the path below:
• TWN4DevPack###\Firmware\Nano Module\TWN4_NKx###_STD201_Nano_Keyboard_Standard.bix
Please see the AppBlaster User Guide for instructions on flashing Firwmare and programming custom
Applications.
2.5. Demo: Reading Cards
The easiest way to demonstrate the reading capability of the TWN4 MutiTech Nano Module is with the
Director software (for Windows), included in the DevPack. To start reading card IDs, execute the Director
software and follow the steps below:
• To setup a connection to the reader, select USB on the Port drop-down menu or, in case of RS232
connection, the appropriate COM port.
• Click the button Connect.
• Enable the checkbox Cycle. This will make the TWN4 MultiTech Nano (LEGIC 42) search for
transponders cyclically.
• Optional: use the Select Tag Types drop-down menu to restrict the types of cards that can be
detected.
• Now just place a transponder near the antenna, and the Director software will print the UID out in
the log window, as shown on Figure 2.3.

3. Using Peripherals
3. Using Peripherals
3.1. Ready-to-Use Functionality on Dev Board
Table 3.1 contains instructions on how to enable built-in functionality of the Development Board. Refer
to TWN4 MultiTech API documentation for detailed instructions on programming these devices. Refer to
Section 2.1 for help locating components on the board.
Peripheral Instructions to Enable
Speaker "COM2-LED & Speaker" DIP Switch bit 2: ON to use Speaker.
Debug LEDs There is a bank of 4 LEDs available next to the "LED Connect" DIP
Switch. Use the DIP Switch to enable individual LEDs. These LEDs
are driven by Nano Module GPIO ports 0-3.
COM-Side LEDs There are 5 LEDs next to the COM ports. These include "Nano Module
Power-ON", and RX/TX traffic indicators for both COM 1 and 2 ports. To
enable these LEDs, set "COM2-LED & Speaker" DIP Switch bit 1 to ON.
For COM2 port, see also entry directly below.
COM Port 2 COM2 port is functional without any extra board changes. To enable
traffic LEDs on COM2 port, set "COM2-LED & Speaker" DIP Switch bits
3 and 4 to ON. See Table B.4 for details.
SAM Slots 1,2 No additional steps needed to activate. Simply insert card.
COM Port 1 Can be used as a general-purpose port if the main interface to Host is
USB (Micro or DF11). Set "COM1 & Power-ON" DIP Switch bits:
1=ON, 2=OFF, 3=ON, 4=OFF.
Also disable RS232 transceiver by floating Pin 8 (MGND) of DF11 port.
RS232 Port Can be used as a general-purpose port if the main interface to Host is
USB (Micro or DF11). Set "COM1 & Power-ON" DIP Switch bits:
1=ON, 2=ON, 3=ON, 4=ON.
The same connector can be used for both USB and RS232.
See Table B.1 for instructions.
Table 3.1.: Ready-to-Use Functionality on Dev Board
3.2. I/O Extender
The I/O Extender serves to provide additional Interfaces to the Nano Module for the customer to interact
with. These include Wiegand, RS485/422, CAN and Relais. An LCD Screen is also available to assist with
application bring-up.
The I/O Extender can be connected to the TWN4 MultiTech Nano Module via the Expansion slot on the
Development Board. Please see the I/O Extender Technical Handbook for more information.
