xPico®200 Certification Firmware Instructions 5
Overview
This document provides instructions on leveraging Lantronix® xPico®certificates. In many
cases, the Lantronix modular transmitter certification can be leveraged without acquiring full re-
certification effort in products that use the Lantronix module.
ThexPico 200 series has modular approval for FCC, IC, EU, Japan, China and Australia/New
Zealand. All xPico certificates can be found in the xPico 200 module documentation at
https://www.lantronix.com/products/xpico-200/#tab-docs-downloads.
It is recommended that you consult with your certification laboratory to develop your
certification plan for your product that includes the xPico 200 series module. The xPico 200
series module certification tests were completed at Bureau Veritas in Hsinchu, Taiwan.
Requirements for Leveraging Lantronix xPico 200 Certificates
The following conditions are required to leverage Lantronix modular transmitter certifications:
 Following the antenna and layout instructions in the xPico 200 Series Integration Guide.
 Using antennas of similar type and equal or less gain than the antennas listed in the
xPico 200 Series Integration Guide.
 Positioning the xPico 200 module at least 20 cm from a human body and the
transmitting antennas at least 20 cm from all other transmitters. Lantronix has not
completed SAR testing on the xPico 200 module.
 Running EMC tests including the FCC 15-part B and EN 301 489 -1/-17. When
leveraging the modular certification, the transmitter and receiver-specific tests normally
do not need to be performed.
 Placing certifications for the xPico 200 transmitter IDs for various regions on the end-
product label according to conditions listed in the Compliance section of the xPico 200
Series Data Sheet.See https://www.lantronix.com/products/xpico-200/#tab-docs-
downloads.
 Running two certification testing modes. See Certification Test Modes.
Disqualifications to Leveraging Lantronix xPico 200 Certificates
The following conditions disqualify the leveraging of Lantronix xPico 200 certifications:
 Using a different type of antenna than that shown in the xPico 200 Series Integration
Guide.
 Using an antenna with higher gain than the antennas called out in the xPico 200 Series
Integration Guide.
 Installing the xPico 200 module antenna in a location where it is expected to be less
than 20 cm from a human body. Under this scenario, SAR testing would need to be
completed.
 Installing the xPico 200 module antenna within 20 cm of another transmitter module.
 Installing the xPico 200 module in a country or region not referenced in the Compliance
section of the xPico 200 Series Data Sheet. See
https://www.lantronix.com/products/xpico-200/#tab-docs-downloads.

xPico®200 Certification Firmware Instructions 6
Certification Test Modes
Certification testing requires both normal mode testing and continuous mode testing. The number
of units needed for certification testing depends on the regional certifications planned. Consult
with your certification lab prior to testing for their recommendation on the number of normal mode
test units and continuous mode test units.
 Normal mode testing is conducted with the xPico 200 module running the base
application software. In this case the unit should be configured to run tests with the
module interfaces both idle and fully exercised. For Ethernet and Wi-Fi interfaces, iperf
or some other network utilization method can be used. Serial and USB ports should
utilize a similar program to exercise the used ports for certification EMC tests.
 Continuous mode testing is conducted in cases where full transmitter certification or
re-certification is required. The certification lab will require testing on some units that
run continuous mode transmitter and receiver tests. To run the continuous transmit and
receive mode tests, special firmware needs to be loaded on the xPico 200 module.
Hardware Requirements for Continuous Mode Testing
The following hardware requirements are needed for continuous mode testing. The continuous
mode software can be downloaded at https://www.lantronix.com/products/xpico-200/#tab-docs-
downloads.
 To run the xPico 240/250 transmitter and receiver tests for full certification, access to
the module serial port is required.
 The serial port connections are required to load a special firmware image that allows
continuous transmit, continuous receive, and other tests required for transmitter
certification.
 Lantronix recommends adding test points for the serial port to assist with loading the
certification test code. The current implementation requires that this data is loaded via
the serial interface. It’s recommended to include an option to tristate other devices
connected to the serial port line while the manufacturing test loading is in progress. An
example of the recommended manufacturing test point is shown in the figure below.

Continuous Mode Software Load
To use the module for continuous mode testing for certification, download and load the Wi-Fi
continuous mode software.
1. Download the xPico 200 continuous mode software from
https://www.lantronix.com/products/xpico-200/#tab-docs-downloads.
2. Extract the files from the archive. The archive contains the xPico200_MFG_Test
directory with the following contents:
a. Wi-Fi-Scripts directory –contains the scripts that can be pasted in Tera
Term.
b. xPico200 directory –contains the rom that is loaded to the device and the Tera
Term macro file.
c. Certification Firmware Instructions –this document.

xPico®200 Certification Firmware Instructions 8
d. xp200-cmd_teraterm –wifi.bat –the batch file that launches Tera Term and
executes the macro.
3. Copy the xPico200_MFG_Test directory to the C:\drive of your PC.
Note: If you copy it to another directory on your PC, you may need to modify the load
scripts to point to a different directory.
4. Install Tera Term on your PC. These instructions were tested with Tera Term 4.73 but
may work with other versions.
Note: The xP200-cmd_teraterm –wifi.bat file contains a link to ttermpro.exe, the Tera
Term executable. You may need to modify this link if the executable is in a different
directory on your PC.
5. Connect the serial port of the module to your PC.
6. Double click the xP200-cmd_teraterm –wifi.bat file in the xPico200_MFG_Test
directory.
7. In the Comport Number window that opens, enter the COM port that’s connected to the
xPico 200 module and click OK.
8. Click OK to start.

xPico®200 Certification Firmware Instructions 9
9. Assert the module default pin and power up the module. The Tera Term window will
display the firmware transfer progress.
10. When the firmware has successfully loaded, a Pass Test window will be displayed.
Note: In some cases, you may need to reset the Tera Term window after loading the
firmware.
11. At the CLI prompt, type cert console to enter continuous mode for running cert scripts.
12. Type ?to list all commands. Type wl -h to list all wl commands.
Running the Wi-Fi Continuous Mode Tests
Wi-Fi continuous mode uses the Cypress WL commands. For more information on WL tool
commands please see the Cypress reference document at
http://www.cypress.com/file/385966/download.
The Wi-Fi scripts directory includes several scripts that can be pasted into the Tera Term
command prompt.
Example scripts are shown below.

Bluetooth Continuous Mode Testing
The steps in http://www.cypress.com/file/298091/download describe how to run the Lantronix
xPico 200 Bluetooth continuous mode scripts. These scripts are based on the Cypress
mybluetool commands for the Cypress processor inside of the xPico 200 module.
Running the BT Test Modes
To run the BT Test Modes, follow these steps:
1. Follow the instructions for each type of test in the Cypress document at
http://www.cypress.com/file/298091/download
2. Load the continuous mode firmware as described in the Continuous Mode Software Load
section.
3. Once the firmware is loaded, run the bt_hci_reset command twice. The second time this
command is run, it should respond with SUCCESS.
4. After the reset command run the bt_download_firwmare command.
5. Table 1 lists the remaining BT commands and syntax. The equivalent commands from
the Cypress document are included.
Note: There are slight differences between the Cypress document command and the
