Commands
The Mate will accept the following commands for controlling FXs only. The Mate only passes
these commands to the master inverter in a HUB stacked system. The master will change the modes of
all slaved inverters to suit. ON, SEARCH, OFF, USE, DROP, AUX ON, and AUX OFF. ON will turn
the FX to ON mode, if no AC input is being used the inverter will provide a constant output. SEARCH
will place the FX in Search mode, allowing for a pulsed AC output when load levels drop below the
programmed limits for that FX. OFF will not allow the FX to invert. It will still charge and pass through
AC depending on the AC mode. These commands will only be passed onto the master inverter in a HUB
based system. USE will allow the AC input to be used if it meets the programmed limits of the FX.
DROP will not allow AC input to be utilized, unless there is an error. Errors will cause the FX to change
the AC mode to USE. AUX ON energizes the 12V Aux output of the FX, AUX OFF de-energizes it.
AUX control is only available for master inverters on a HUB. For more information on FX operational
modes, download the FX manual at
http://www.outbackpower.com/manuals.htm .
Commands are sent as ASCII
characters, the same character is sent twice for
error checking. Figure 14 shows a chart of
utilized commands.
Command Timing
The Mate will
send a Status Page for
each FX it is connected
to, either directly or via
a HUB. A Mate
directly connected to a
FX will send out a
single Status Page per
second, if a HUB is
used, Status Pages for
all FXs will be
transmitted once a
second. The Mate
listens for commands
starting with the first
byte it transmits, it will
continue to listen for
~200 to 250 mS after
transmission starts (See
Figure 15).
