1. Introduction

This document is a dedicated set of instructions for using the US60L evaluation kit. It comes as a
complement to the “Troubleshooting guide” which is a more generic set of instructions for any
Sequans-based solution.

It is valid for Sequans LTE solutions based on UE4.1.3.0 onwards (with SW builds LR4.1.3.0
onwards).

It can be used for lab or field testing purpose.

2. Set-up description

The DUT is delivered as an evaluation kit with the US60L soldered on an M.2 board, connected to a
main board.

Depending on the testing type that will be executed, the user may need additional RF cables (lab test
or IOT testing), USB cable (for connection to the laptop, valid for any type of testing), a pair of
antennas (for field or lab over-the-air testing), and a 2FF SIM card.

Please refer to “Appendix A” for some illustrations on how to connect the RF cables, the USB cable
and insert a 2FF SIM card.

Prior to following the instructions below, please check that you have been provided with a USB driver
(file format like ATT_413021962_2015_11_18.exe) and a DM Tool (file format like
sqn4gdm_setup_12274exe_2015_11_16.exe)

3. General instructions

The DUT has been previously screened and flashed in FFF (FW From Flash) mode: the FW will be
executed from the module, rather than from the host driving the DUT.

Please follow the recommendation in the “Appendix B”, if you want to upgrade to a new firmware.
Prior to any operation, please make sure that you

- Install the Sequans driver and tools on the host PC. Instructions are provided in the
“Troubleshooting guide”, section “2. USB drivers installation” (using the executable
ATT_413021962_2015_11_18.exe)

- Connect the DUT according to “Appendix A” (RF cable, USB cable, SIM insertion…)

Now the device should be ready to operate. You may want to install the DM (Diagnostic and
Monitoring) tool to assist you in the monitoring and debugging activities while using US60L. The DM
tool installation guide can help you through this process. The Troubleshooting guide can help you
through the DM tool usage.

Prior to any other operation (lab or field on AT&T network), please

- Check if device configuration is correctly set for the AT&T test type, using following
commands using ACM COM port (with configuration 115200-8-n-1)

Several network interface ports are available on the DUT

- 2 ECM (Ethernet) with IP 192.168.15.1 and 192.168.16.1

- 1 x ACM(serial) with dedicated COM port number

The automation manager can control the UE by sending AT command through ECM or ACM over
USB

- ECM with IP address 192.168.16.1 port 4664 (Yellow line)

- ACM serial with speed 115200 and dedicated COM port number (Red line).

The specific automation scripts are provided by Sequans and can be used by the certification lab.
