NAME

       optiups - Driver for Opti-UPS (Viewsonic) UPS and Zinto D (ONLINE-USV) equipment

NOTE

       This man page only documents the hardware-specific features of the optiups driver. For
       information about the core driver, see nutupsdrv(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 models.

       This driver additionally supports a Zinto D from ONLINE USV-Systeme AG because of their
       very similar commands, but it is 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) file:

       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.

       fake_lowbatt
           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.

           For basic shutdown configuration testing, the command upsmon -c fsd is preferred.

       powerup
           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 the UPS!

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.
