optiups - Driver for Opti-UPS (Viewsonic) UPS and Zinto D (ONLINE-USV)
This man page only documents the hardware-specific features of the
optiups driver. For information about the core driver, see
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
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.
This driver supports the following optional settings in the
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.
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
This forces the low battery flag true. Without it, if you want
to test your UPS, you will have to unplug it and wait until the
battery drops to a low/critical voltage level before nut will
respond and power down your system. With the flag, nut should
power down the system soon after you pull the plug. When you
are done testing, you should remove this flag.
Zinto D from ONLINE-USV cannot be identified when switched to
standby. Set this flag to allow the driver to power-up your
Zinto UPS. This will also power-up your equipment connected to
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.
