NOTE

       This  man  page  only  documents  the hardware-specific features of the
       megatec driver. For information about  the  core  driver,  see  nutups-
       drv(8).

SUPPORTED HARDWARE

       The  megatec  driver  is  known to work with various UPSes from Blazer,
       Energy Sistem, Fenton Technologies, Mustek and  many  others.  The  NUT
       compatibility table lists all the known supported models. Keep in mind,
       however, that other models not listed there may also be  supported  but
       haven't been tested.

       On  models  with  both a serial port (RS-232) and an USB port, only the
       serial port is supported.

EXTRA ARGUMENTS

       mfr=string

              Optional.  Specify the UPS manufacturer name.


       model=string

              Optional.  Specify the UPS model name.


       serial=string

              Optional.  Specify the UPS serial number.


       lowbatt=float

              Optional.  Low battery level (%). Overrides the hardware default
              level.


       ondelay=int

              Optional.  Delay before the UPS is turned back on (minutes).


       offdelay=int

              Optional.  Delay before the UPS is turned off (minutes).


       battvolts=float:float

              Optional.  The battery voltage interval (volts).

       load.off
              Turn off the load immediately.


       reset.input.minmax
              Reset minimum and maximum input voltage status.


       reset.watchdog
              Restarts the UPS watchdog timeout. The watchdog is started if it
              isn't running, which means the UPS shuts down one  minute  after
              this  command  is  executed  for  the  last time, restarting one
              minute afterwards.  To  cancel  the  watchdog,  run  the  "shut-
              down.stop" command.


       shutdown.return
              Turn off the load and return when power is back.


       shutdown.stayoff
              Turn off the load and remain off.


       shutdown.stop
              Stop a shutdown in progress.


       test.battery.start.deep
              Perform a long battery test (Not available on some hardware.)


       test.battery.start
              Perform a (10 second) battery test.


       test.battery.stop
              Stop a running battery test. (Not available on some hardware.)

USER VARIABLES

       The  behavior  of  the  driver can be controlled by some user definable
       variables (see upsrw(8)):


       ups.delay.shutdown
              Interval to wait after shutdown with delay command (seconds)


       ups.delay.start
              Interval to wait before (re)starting the load (seconds)


       Some  models report a bogus value for the beeper status (will always be
       "enabled" or "disabled"). So, the "beeper.toggle" command may appear to
       have  no  effect in the status reported by the driver when, in fact, it
       is working fine.

       The temperature value is also known to be bogus in some models.
