3 PAN9420 Overview
3.1 Features
The PAN9420 is an all-inclusive, embedded Wi-Fi module. It contains an integrated IoT-ready
web-stack that offers and provides many key IoT features.
For detailed and up-to-date list and description of all available features, please read the
PAN9420 Communication Specification available in the download section on our
website:

3.2 Interacting with the Evaluation Kit
The PAN9420 Eval Kit is an evaluation and design platform for the PAN9420 Module. There are
two optional methods to interact with the PAN9420 using the Evaluation Kit:
3.2.1 Wired
This method uses the provided USB ports with USB0 for commands and USB1 for data. Using
this scheme, you will also need to use the Terminal program and the WIFIgurator. You will be
able to:
Interact with the various SW modules provided by the integrated stack
oIssue commands
oReceive acknowledgment (and Error codes)
Stream data
Upload new:
oWeb server content
oServer and Client certificates
oClient private keys
oConfiguration files
3.2.2 Wireless
This method is using the Wi-Fi connection and allows the user to access the web server, and
interact with its content. You can still interact with the stack, given that the webserver provides a
command interface to the stack.
Please note that the two methods are distinct, and complementary to each other, yet, they
share some limited overlapped functionality.

3.3 Powering the Evaluation Kit
3.3.1 General
To power up the evaluation kit, please choose between the following two methods
1. External Power
Use X2 and X3 to provide 5V power from an external source. An external source can be
a battery or a Power Supply. This method allows users to perform some power
measurements.
The power provided to the board must be 5V DC.
2. USB connection
a. Connect the MB’s USB0 Port to your Computer’s USB-Port.
b. Alternatively, a portable power-bank which provides 5V can be used to power
up the Eval Kit.
Using USB0 to power up the Eval Kit is the recommended method.
On the PAN9420 Evaluation Kit:
USB0 is connected to the PAN9420’s UART0.
UART0 is primarily utilized to send commands to, and receive
acknowledgments between the PAN9420 and the Host.
USB1 is connected to the PAN9420’s UART1.
UART1 is employed by the following SW Modules to stream data:
oNetcat
oWebcat
oUDP
oHTTP client
oMQTT client
oFirmware update
oCMD to BIN UART tunneling

4 First Time Set Up
4.1 Powering
As mentioned above, to connect to and communicate with the Evaluation Kit and the PAN9420,
you will need a PC with your choice of OS. Additionally, you will need the following tools to be
installed on it:
A browser
A Terminal program to send and receive datagrams
Alternatively, or additionally to the Terminal you will need the WIFIgurator
Please choose your preferred powering method as per 3.3 Powering the Evaluation Kit
above.
Once power is applied, the Eval Kit will power on and go through initialization. The boot and
initialization takes a few seconds.
The subsequent LEDs on the ETU will light up as follows:
1. VCC Constantly on
2. READY Constantly on
3. MSTATUS Blinking
WSTATUS might be blinking periodically, which indicates the modules
scanning process.
Please see below illustration of the LED position:
Figure 6: ETU LED position

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 15
4.2 Connecting the Evaluation Kit
As mentioned above in 3.2 Interacting with the Evaluation Kit there are two optional methods
to connect and interact with the PAN9420, please choose your preferred method, and use the
following to interact with the PAN9420.
4.2.1 Wired –Connecting through USB0 and a Terminal Program
Simply connect the provided USB Type-B cable to USB0 of the MB and to a port in your
computer.
In the very first time connecting the USB0 of the MB to your PC, and given
that the FTDI driver is NOT pre-installed on your machine, you will be asked to
install the FTDI drivers.
After successfully installing the FTDI driver, your PC will enumerate two virtual COM ports. One
is for JTAG-via-USB (mostly it is the lowest COM number of the two) and the other one is
connected to PAN9420’s UART0 (mostly it is the highest COM number of the two).
On a Windows machine, use the device manager to discern which COM number corresponds to
UART0. After connecting the evaluation kit to your PC, in device manager > ports, you should
see two COM ports (see below). Generally, the port with the highest number of the two
corresponds with UART0. In the example below, you will use COM19.
Figure 7: Device Manager and virtual COM ports
To test the Command Interface via USB0 you could use any terminal program, Panasonic’s
terminal program of choice is HTerm.

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 16
Default configuration for UART0 and UART1:
Baud rate: 115200
Data bits: 8
Parity bit: none
Stop bits: 1
UART0 does not utilize any flow control.
UART1 utilizes HW flow control (RTS/CTS). To achieve maximal throughput,
flow control for UART1 is required.
If successfully connected, try to send the command get system firmware using your
Terminal Program of choice, to request the firmware version of the module.
A command MUST BE followed by CR (Carriage Return) and LF (Line Feed)
as described in the communication specification. You can set your terminal to
issue them automatically.
You might also need to set the terminal’s echo.
If you did not use HTerm before, please note:
If you are new to HTerm, please do not use the ASend button.
To invoke a command in Hterm –
Type it in
Press [Enter] on your keyboard
Figure 8: Invoking a command in HTerm

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 17
The response from the PAN9420 should be received like in the received window of the HTerm-
based example below:
Figure 9: Terminal Set Up and Response

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 18
4.2.2 Wired –Connecting through USB0 and the WIFIgurator
An alternative to using a Terminal Program is using the WIFIgurator provided by Panasonic.
The WIFIgurator incorporates Terminal like capabilities, along with an easy-to-use GUI.
As in 4.2.1 Wired –Connecting through USB0 and a Terminal Program, connect the MB’s
USB0 to your PC’s USB port using the provided USB Type-B cable.
From the WIFIgurator’s directory (see 2.2 Additional Equipment), double-click the executable
WIFIgurator.exe.
Figure 10: WIFIgurator Directory
You will see the WIFIgurator’s GUI along with the Welcome Page.
Figure 11: WIFIgurator Welcome

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 19
To start the program, read the general Terms and Conditions, then click on the Accept and
Start button. In order to read out the modules firmware, MAC address, serial number, radio
version, bootloader version and hardware revision, perform the following steps:
1. On the top, choose the corresponding COM port. It is the same as used in 4.2.1
Wired –Connecting through USB0 and a Terminal Program.
2. Click the Connect button.
Figure 12: WIFIgurator connection
3. Lastly click on the Read Out button.
4. You should see a response in the Communication part of the GUI:
Figure 13: WIFIgurator Reading Info

PAN9420 Quick Start Guide
Quick Start Guide Rev. 1.0 Page 20
Using the WIFIgurator you will be able to
Issue commands and see the response
Easily and using the GUI, set major key features
Convert your HTML code to a firmware update file (.fwu)
Load the firmware onto the module
4.2.3 Wireless –Connecting through Wi-Fi
To connect to the PAN9420 through Wi-Fi, all you need to do, is to apply power to the
Evaluation Kit (see 3.3 Powering the Evaluation Kit).
Once the board is powered and initialized, activate the WLAN Network Manager on your PC or
Smart Device.
In Windows based machines, it is mostly on the bottom right corner of the screen.
Your device will scan for new wireless Access Points (APs):
Look for the SSID PAN9420_AP.
Connect to PAN9420_AP.
The standard connection is protected with a WPA2 key. When prompted to enter a
password, please enter the default password: PAN_9420.
