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. Acquire the latest updater application from licor.com/8250-software and install it on your computer.
  2. The updater is available for both Windows and macOS computers.
  3. Power on the LI-8250 Multiplexer, 8250-01 Extension Manifolds, and your LI-COR long-term chambers.
  4. Connect the LI-8250 Multiplexer to your computer or your local network using an Ethernet cable.
  5. Launch the updater application on your computer.
  6. The updater will display a list of all the LI-8250 Multiplexers on your network by serial number. If you need to find the serial number for a multiplexer, see Figure 2‑4.
  7. Select the multiplexer to update and then click Update LI-8250.
  8. The next window shows the connected instruments that need updating.
  9. Click Update and the application will load the new files onto the selected instruments.
  10. Depending on the size of your system, updating the firmware may take several minutes or may take up to a couple of hours. Be sure that the computer and the multiplexer are powered on until the update is finished.

Note: Do not allow your computer to enter sleep mode while updating.
