Updating the firmware

The firmware that runs on the LI-8250 Multiplexer, 8250-01 Extension Manifold, and the 8200-104/C Long-Term Chambers may need to be updated periodically. Firmware updates include new features and bug fixes. We recommend that you always run the most current firmware on your instruments.

To update the firmware:

  1. With all components of your system connected and powered on, connect using a web browser.
  2. We recommend a wired network connection rather than Wi-Fi.
  3. Acquire the latest updater application.
  4. You can download it through the LI-8250 interface, click Tools > Firmware Updates > Download Latest Version or from licor.com/8250-software. The updater is available for both Windows and macOS computers.
  5. Install the updater application on your computer and launch it.
  6. The updater will display a list of all the LI-8250 Multiplexers on your network by serial number.
  7. Select the multiplexer to update and then click Update LI-8250.
  8. The updater presents a list of connected devices and the firmware status for each.
  9. Click Update and the application will load the new files onto the selected instruments.
  10. Depending on the number of components requiring an update, the update procedure may take from a few minutes to a few hours. Be sure that the computer and the multiplexer remain powered on until the update is finished. Also be sure your computer does not enter a sleep or stand-by state during the update.
