oneac - Driver for Oneac UPS equipment This man page only documents the hardware-specific features of the oneac driver. For information about the core driver, see nutupsdrv(8). This driver supports various Oneac UPS families: • EG (late 80s, early 90s, plug-in serial interface card) • ON (early and mid-90s, plug-in serial interface card) • OZ (mid-90s on, DB-25 std., interface slot) • OB (early 2000&#8217;s on, big cabinet, DB-25 std., interface slot) If your UPS is equipped with the Basic Interface card, use the genericups(8) driver. This driver supports the following optional settings in the ups.conf(5) file: testtime=num Change battery test time from the 2 minute default. offdelay=num Change shutdown delay time from 0 second default. This driver supports the following Instant Commands. (See upscmd(8)) shutdown.return Turn off the load possibly after a delay and return when power is back. shutdown.stop Stop a shutdown in progress. shutdown.reboot Shut down the load briefly while rebooting the UPS. test.failure.start Starts a 15 second long simulation of an input power failure. test.battery.start.quick Start a "quick" battery test. The default time is 2 minutes. This time can be set in the ups.conf file. See testime above. test.battery.stop Stops a battery test that is in progress. reset.input.minmax Reset the minimum and maximum input line voltage values seen since the last reset or power on. test.panel.start Start testing the UPS panel. test.battery.start.deep Start a "deep" battery test. This test runs the UPS until the low battery point and then returns to the AC line. reset.input.minmax Reset the minimum and maximum input line voltage values seen since the last reset or power on. beeper.enable Enable UPS beeper/buzzer. beeper.disable Disable UPS beeper/buzzer. beeper.mute Mutes the UPS beeper/buzzer for the current alarm condition(s). See upsrw(8) to see what variables are writable for the UPS.

Note
If your UPS supports writing battery.runtime.low, the new set value is to be entered in minutes (up to 99) but the reported value is reported in seconds (set value * 60).

Note
If your UPS supports input.transfer.low and input.transfer.high, those values are used to create an allowable output range. The UPS will do what it can to keep the output voltage value within the defined range (for example: tap change or switch to inverter). • Bill Elliot <bill@wreassoc.com> • Eric Lawson <elawson@inficad.com> nutupsdrv(8) The NUT (Network UPS Tools) home page: https://www.networkupstools.org/
