4. Setup

The EM7455 is an internal M.2 module requiring installation into a compatible host device. Please follow these general steps:

1. Prepare Host Device: Ensure your host device (e.g., laptop, industrial PC, router) has a compatible M.2 slot (typically Key B or Key B+M for WWAN modules). Power off and disconnect the device from all power sources before proceeding.
2. Install Module: Carefully insert the EM7455 module into the M.2 slot. Secure it with the appropriate screw.
3. Insert SIM Card: Locate the SIM card slot on the module or host device. Insert a compatible 1.8V or 3V Nano-SIM card.
4. Connect Antennas: Connect the Main, Aux/GNSS, and optional GNSS antennas to the corresponding connectors on the module. Ensure a secure connection for optimal performance.
5. Power On Device: Reassemble your host device and power it on.
6. Driver Installation: Upon first boot, the operating system may automatically detect and install drivers. If not, you may need to manually install drivers for Windows (7, 8.1, 10), Linux (Standard ECM), or Android RIL, typically provided by your host device manufacturer or Sierra Wireless.

  • Verify that the host device's BIOS/UEFI settings allow for M.2 WWAN modules.
  • Check if the necessary drivers are installed and up to date.
• No Network Connection:
  • Confirm the SIM card is correctly inserted and activated with a valid data plan.
  • Check antenna connections; ensure they are securely attached to the Main and Aux ports.
  • Verify network settings in your operating system.
  • Ensure you are within cellular network coverage.
• Poor Signal Strength:
  • Check antenna placement and ensure they are not obstructed.
  • Consider using higher gain antennas if operating in areas with weak signal.
• GNSS Not Working:
  • Ensure the GNSS antenna is connected (if applicable) and has a clear view of the sky.
  • Verify that GNSS services are enabled in your host device's software.
