NOTE

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

SUPPORTED HARDWARE

       optiups was originally written against a PowerES 280es in nut-0.45.  It
       was  revised  for  nut  2.0.1 and tested against a PowerES 420E.  It is
       expected to work with at least the PowerES, PowerPS, and  PowerVS  mod-
       els.

       This  driver additionally supports a Zinto D from ONLINE USV-Systeme AG
       because of their very similar commands, but it's  unknown  if  it  also
       works with other ups from them.

       This  driver  will  not  work with the PowerES stock serial cable.  You
       will need to construct your own three conductor cable:

              UPS 6 -> PC 3
              UPS 9 -> PC 2
              UPS 4 -> PC 5

       The cable for Online-USV uses pin UPS 7 (not UPS 4) -> PC 5.

EXTRA ARGUMENTS

       This  driver  supports  the  following   optional   settings   in   the
       ups.conf(5):


       status_only

              Only  poll  for  critical  status  information.   Without  this,
              optiups (and all nut drivers) poll all sorts of information from
              the  UPS  fairly often.  It is probably not often enough to hurt
              anything, so this option probably is not very useful, unless you
              have a flaky serial connection or a highly loaded machine.


       nowarn_noimp

              Does  not print warnings when the UPS reports that a variable is
              not implemented or not pollable.  Without the  option  you  will
              get  a  message sent to your system logs each time nut polls the
              ups.  If you specify nowarn_noimp, this  message  will  only  be
              logged once.

BUGS

       On  the  420E, ups.serial and ups.temperature are unsupported features.
       This is not a bug in nut or the nut driver, just  the  way  things  are
       with this UPS.
