3.4 STANDALONE/DRIVER WORKING MODES
Two different working modes are provided:
•
Stand-alone:
the device works in stand-alone mode. The system configuration can
be totally set through user interfaces. Pre-correction curves are automatically
selected according to channel and power range.
•
Driver:
the device works in a driven system. The system configuration cannot be
totally set through user interfaces. Some settings are disabled on the user interfaces
in order to be driven by serial interface commands. Pre-correction curves are not
automatically selected according to channel and power range, but the selection is
manually performed through serial interface commands.
The following table lists the commands, specific to each system interface, which must be
enabled or disabled while working in Driver mode.
Note: Diver mode is a specific working mode available and used only in N+1 configuration
systems.
