About this device

I’ve successfully tested the nutdrv_qx driver with the Digitus DN-170076 UPS, connected via USB (it has a DB-9 serial interface as well).

Device manufacturer: Digitus (by ASSMANN Electronic GmbH, www.assmann.com)

Name: DN-170076 Line-Interactive UPS-System, capacity 2000VA/1200W

EAN 4016032441380

With this configuration:

 [digitus]
   driver = "nutdrv_qx"
   port = "auto"
   desc = "Digitus UPS 2000VA/1200W (via USB)"
   vendorid = "0001"
   productid = "0000"
   product = "MEC0003"
   vendor = "MEC"
   default.battery.voltage.low = 20.81
   default.battery.voltage.high = 27.40

…it is detected with Q1 protocol and basically works (except the button.toggle command did not work with neither blazer_usb nor nutdrv_qx drivers with Q1 protocol).

After adding:

   protocol = "megatec"
   novendor

…the button.toggle works and is displayed properly by upsc.

I did a shutdown test with modified settings, to shorten the shutdown time:

   override.battery.charge.low = 30
   default.battery.voltage.low = 25.20
   runtimecal=60,100,80,50

As UPS does not report battery.charge, battery.runtime on its own, have to provide the default.battery.voltage.{low,high} values as mentioned in the man page (otherwise the driver issues "No values provided for battery high/low voltages in ups.conf"), and added runtimecal setting too.

upsc reports the values below when running on main power.
