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

Synopsis

optiups -h

optiups -a UPS_NAME [OPTIONS]

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​.
