Confidential and Proprietary SEQUANS Communications 6 1 LM63S1 Product Description 1.1 Product Features The LM63S1 is an mPCIe module supporting LTE bands B4, B13 and B14. The LM63S1 can be fitted into a mPCIe host connector in (e.g.) a vehicular modems and be connected to a USB port using a mPCIe/to USB connector. 1.2 Software Description The LM63S1 is a hostless device. All the required software is present in the device’s Flash memory: • LTE stack software • Hardware configuration parameters • Application software, including Linux openWrt kernel 2 Installation Procedures 2.1 Prerequisites 2.1.1 Hardware Sequans’ LM63S1 requires a Windows® PC, running Windows 8 or Window7 with an USB 2.0 port. It can also be used with a computer running MAC OS or Linux. .
Confidential and Proprietary SEQUANS Communications 7 2.2 First Installation 2.2.1 Install the Host Software Without plugging in the device, launch the Windows installer. File name is sqn_setup_3.3.3.0-msi-xxxxx-host-only.exe. It automatically installs the Sequans’ LM63S1 drivers on the PC. Follow the procedure: 1. Launch the installer and confirm its execution. Click Yes button to start the installation process. 2. Click the Next> button. 3. Select the installation directory. The default directory can be changed by clicking the Browse... button. Click Next when the appropriate directory is selected. 4. Verify the installation directory and click Install if no change is required. You can update the installation directory by clicking the Back button at this stage. 5. Check the box to trust Sequans software and proceed with the installation process. 6. Click Finish to complete the installation process. 2.2.2 Install the DM Tool Software This is an optional step. Please refer to DM tool’ user manual. 2.3 LM63S1 Board Connection After the installation of the Host Software is completed, you can plug the device in an USB port. Three drivers should be installed: • One composite driver, • One serial over USB driver (SqnAcm) to control the device using AT commands • One Ethernet over USB driver (SqnUsb) to transport the data traffic between the device and the PC 1. Plug the LM63S1 on an USB port of your PC. 2. Wait for the automatic driver installation. It takes some time (a few dozens of seconds) before the evaluation kit is properly identified on the USB interface. 3. When the process is completed, the PC indicates that the device is ready to use. You can launch a PuTTY Windows and use AT commands. Sequans LTE UE products implement the standard 3GPP 27.007 AT commands.
Confidential and Proprietary SEQUANS Communications 8 2.4 Connection to Serial Port Using a terminal emulator application (e.g PuTTY on Windows®), open the installed serial port @ 115200 bauds, 8 data bits, 1 stop bit, no parity and no flow control. Next figure illustrates a PuTTY configuration. Note: Find the COM serial port used by the Evaluation Kit with the Windows® Devices settings, when the installation is complete. Select the SQN31X0 device in the Windows devices list, and right-click to read its properties. The COM port number assigned to Sequans CDC/ACM USB interface can be found on the Hardware tab as illustrated on next figures
Confidential and Proprietary SEQUANS Communications 9 Note: Ping the interface IP address to confirm that the installation is operational. 2.5 Software Uninstallation Use Windows’ uninstaller service.
Confidential and Proprietary SEQUANS Communications 10 3 General Procedures 3.1 Connect the LM63S1 For the first installation of the LM63S1 on the PC, please follow the procedure described in Section 2. There is no other specific operation required for the later connections. Plug the LM63S1 on a USB port of your PC and wait for the “Device ready” Windows message display. The LM63S1 is then ready. 3.2 Connection to Serial Port Open a PuTTY terminal and use regular AT commands to control the LTE modem 3.3 Disconnect the LM63S1 Use Windows standard Eject device procedure before physically disconnect the LM63S1. 3.4 Programming Instructions See Applications Software Development Guide.

HW integration guidelines RF connections When attaching antennas to the module: Note: To disconnect the antenna, make sure you use the specific RF connector to prevent damage to the module or coaxial cable assembly. •Use the specific RF connector to attach antennas to the module’s connection points. •Match coaxial connections between the module and the antenna to 50 Ohm. •Minimize RF cable losses to the antenna; the recommended maximum cable loss for antenna cabling is 0.5 dB. •To ensure best thermal performance, if possible use the mounting holes to attach (ground) the device to the main PCB ground or a metal chassis. Note: If the antenna connection is shorted or open, the modem will not sustain permanent damage. Shielding The module is fully shielded to protect against EMI and must not be removed. Antenna and cabling When selecting the antenna and cable, it is critical to RF performance to match antenna gain and cable loss. Choosing the correct antenna and cabling When matching antennas and cabling: •The antenna (and associated circuitry) should have a nominal impedance of 50 Ohms with a return loss of better than 10 dB across each frequency band of operation. •The system gain value affects both radiated power and regulatory (FCC, IC, etc.) test results. Designing custom antennas Consider the following points when designing custom antennas •A skilled RF engineer should do the development to ensure that the RF performance is maintained. Determining the antenna’s location When deciding where to put the antennas:
Confidential and Proprietary SEQUANS Communications 12 •Antenna location may affect RF performance. Although the module is shielded to prevent interference in most applications, the placement of the antenna is still very important — if the host device is insufficiently shielded, high levels of broadband or spurious noise can degrade the module’s performance. •Connecting cables between the module and the antenna must have 50 Ohms impedance. If the impedance of the module is mismatched, RF performance is reduced significantly. •Antenna cables should be routed, if possible, away from noise sources (switching power supplies, LCD assemblies, etc.). If the cables are near the noise sources, the noise may be coupled into the RF cable and into the antenna. Ground connection When connecting the module to system ground: •Prevent noise leakage by establishing a very good ground connection to the module through the host connector. •Connect to system ground using the two mounting holes at the top of the module. •Minimize ground noise leakage into the RF. Depending on the host board design, noise could potentially be coupled to the module from the host board. This is mainly an issue for host designs that have signals traveling along the length of the module, or circuitry operating at both ends of the module interconnects. 5 FCC Regulations This module is designed to meet, and upon commercial release, will meet the requirements of the following regulatory bodies and regulations, where applicable: o Federal Communications Commission (FCC) of the United States o The Certification and Engineering Bureau of Industry Canada (IC) Upon commercial release, the following industry approvals will have been obtained, where applicable: o PTCRB for B14 Additional certifications may be obtained upon customer request — contact your Sequans Communications account representative for details.
