This instruction describes how to update a new ceilometer firmware version.

This instruction describes how to update the CL31 firmware. The same procedure applies to CL51.
The update requires:
  • Serial connection to the ceilometer
  • Terminal program
  • CL31 firmware from docs.vaisala.com

You can update the firmware through the maintenance port or the data port. Vaisala recommends using a direct serial port connection for best performance, but you can also upload it through RS-485 or modem. The upload time depends on the connection speed.

  1. Open a terminal program, such as HyperTerminal or Tera Term.
  2. To establish a connection, type open.

    CL31 prompt opens.

  3. To check your current firmware version, type version.
  4. When prompted, type the password advanced.

    The ceilometer responds: Service password accepted.

  5. To start the software update, type service sw_update

    The ceilometer responds: SW download. Start the file transfer.

  6. Send the new software, such as CL31_V2014.bnm, with the terminal program as a plain text file without any protocol.

    The file transfer starts. Depending on the connection type, the file transfer may take 3-15 minutes.
