If an incorrect command is sent, a “bad command” message will be
received. The example that follows sends the incorrect command “set unit
ppm” instead of the correct command “
set gas unit ppm
.”

Receive: set unit ppm bad cmd
The “save” and “set save params” commands stores parameters in FLASH. It
is important that each time instrument parameters are changed, that this
command be sent. If changes are not saved, they will be lost in the event of
a power failure.
Table B-1 lists the 49 i C-Link protocol commands. The interface will
