This driver is the only NUT driver which will work with your UPS (tripplite_usb is for older models with built-in USB-to-serial adapters). I don't see any changes to drivers/tripplite-hid.c past v2.6.5 which would add support for that setting. If you have access to the vendor's original software, that might be a quick thing to test. Some lower-end models tend not to have all of the features. Based on the spreadsheet in an email from Tripp Lite last fall: http://article.gmane.org/gmane.comp.monitoring.nut.user/8173 ...the OMNI900LCD shares the same "protocol ID" (2010) as the SMART1000LCD, and the latter only seems to support "ups.delay.shutdown": http://buildbot.networkupstools.org/~buildbot/cayman/docs/latest/ddl/Tripp_Lite/SMART1000LCD.html If there are signs that the variable is provided by the UPS, but just missing from NUT, you can stop the driver, and re-run it with the following parameters for a minute or two.
