    How to perform a firmware upgrade the in the B450 using TeraTerm.

    1. Navigate to http://US.Boschsecurity.com. Browse to: Product Catalog > Intrusion Alarm Systems > Conettix Communications > Conettix Communicators. Select the B450 Product Page and click on the Software Downloads Tab.
    2. Download and save the latest firmware file to a location on the computer, then extract the files from the ZIP file. The firmware file required for use with TeraTerm ends with a *.kfw extension.
    3. Remove the B450 from the control panel and remove the cell card from the B450.
    4. Set the address wheel on the B450 to 0 and reconnect the B450 to the control panel.
    5. Connect a USB A to USB A cable (Bosch p/n B99) between a computer and the B450. When using a store purchased cable, be sure to use a ‘Computer to Peripheral ‘cable and not a ‘Computer to Computer’ type cable.
    6. Open TeraTerm.                                                                                                                                                                             TeraTerm Icon.png

    14. Close the TeraTerm session, and relaunch TeraTerm.
    15. Log into TeraTerm to reestablish the connection. Communication between the control panel and B450 restores.
    16. Remove power from the B450 and place the cell card back into the B450.
    17. Set the device address as required for the configuration in use.
