| - | xS/xG series extensions can be upgraded similarly. Instead of **fwspi** utility, just use the alternative named **fwserial** which is also included in the //unipi-firmware-tools// package (installed automatically with //unipi-firmware//). The command-line arguments are very similar as for the fwspi, except RS485 port specification. | + | xS/xG series extensions can be upgraded similarly.

| - | The -p (path) parameter must be set according to the RS485 used for the extension. See section [[en:hw:01-axon:portmap|]] to resolve the appropriate path for each RS485 available within your unit. For example, if extension is connected to //RS485-1/RS485-1.1//: <code>/opt/unipi/tools/fwserial -p /dev/ttyNS0 -P </code>. | + | Make sure that there is no other application using/communicating on the used port and do not disconnect power to the Controller or Extension. Any of this will lead to bricking the extension. |
