       ups.conf - UPS definitions for Network UPS Tools

       This  file is read by the driver controller upsdrvctl, the UPS drivers that use the common
       core (see nutupsdrv(8)) and upsd(8).  Each UPS gets its own section, and that section con-
       tains a number of directives that set parameters for that UPS.

       The  section begins with the name of the ups in brackets, and continues until the next UPS
       name in brackets or until EOF.  The name "default" is used  internally  in  upsd,  so  you
       can't use it in this file.

       You must define the "driver" and "port" elements for each entry.  Anything after that in a
       section is optional.  A simple example might look like this:

			driver = fentonups
			port = /dev/ttyS0

       A slightly more complicated version includes some extras for the hardware-specific part of
       the driver:

			driver = apcsmart
			port = /dev/cua00
			cable = 940-0095B
			sdtype = 2

       In  this  case,	the apcsmart(8) driver will receive variables called "cable" and "sdtype"
       which have special meanings.  See the man pages of your driver(s) to learn which variables
       are supported and what they do.

       driver Required.   This	specifies which program will be monitoring this UPS.  You need to
	      specify the one that is compatible with your hardware.  See nutupsdrv(8)	for  more
	      information  on  drivers in general and pointers to the man pages of specific driv-

       port   Required.  This is the serial port where the UPS is connected.  On a Linux  system,
	      the  first  serial  port usually is /dev/ttyS0.  On FreeBSD and similar systems, it
	      probably will be /dev/cuaa0.

	      Optional.  When you have multiple UPSes on your system, you usually  need  to  turn
	      them off in a certain order.  upsdrvctl shuts down all the 0s, then the 1s, 2s, and
	      so on.  To exclude a UPS from the shutdown sequence, set this to -1.

	      The default value for this parameter is 0.

       nolock Optional.  When you specify this, the driver skips the port locking routines  every
	      time it starts.  This may allow other processes to seize the port if you start more
	      than one accidentally.

	      You should only use this if your system won't work without it.

	      This may be needed on Mac OS X systems.

	      Optional.  This can be set as a global variable above your first UPS definition and
	      it  can  also be set in a UPS section.  This value controls how long upsdrvctl will
	      wait for the driver to finish starting.  This keeps your system from getting  stuck
	      due to a broken driver or UPS.

	      The default is 45 seconds.

       All  other  fields  are	passed	through to the hardware-specific part of the driver.  See
       those manuals for the list of what is allowed.

       upsdrvctl(8) uses this file to start and stop the drivers.

       The drivers themselves also obtain configuration data from this file.  Each  driver  looks
       up its section and uses that to configure itself.

       upsd(8)	learns	about  which UPSes are installed on this system by reading this file.  If
       this system is called "doghouse" and you have  defined  a  UPS  in  your  ups.conf  called
       "snoopy", then you can monitor it from upsc(8) or similar as "snoopy@doghouse".

       Additionally,  the  first UPS in this file is the default ups in upsd.  If you tell one of
       the clients to monitor a UPS by the hostname alone  ("doghouse",  without  any  @  or  ups
       name),  it  uses the default UPS.  If you have multiple UPSes or if you just want to avoid
       ambiguities, always specify the upsname and hostname with the client software.
