NAME

       riello_ser - Driver for Riello UPS Protocol UPS equipment via serial port connections

SYNOPSIS

       riello_ser -h

       riello_ser -a UPS_NAME [OPTIONS]

           Note

           This man page only documents the hardware-specific features of the riello_ser driver. For information
           about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

       riello_ser supports all recent Riello UPS, Aros UPS models which use the Riello UPS GPSER and SENTR
       protocols.

       Older Riello UPS products are not supported.

EXTRA ARGUMENTS

       You may need to tweak some settings, depending on the make and model of your UPS (see ups.conf(5)):

       localcalculation
           When enabled, driver will calculate values of battery.runtime and battery.charge "locally" in the
           driver. This is for some Riello models which provide incorrect values in hardware readings, or none
           at all. This "local calculation" is done according to nominal battery capacity, nominal battery
           voltage, actual battery charge, maximum and actual UPS load.

           You may want to also configure default.battery.voltage.low and default.battery.voltage.high in case
           the built-in default range (from 10.7V to 12.9V) does not match your hardware, or give a shot to
           default.battery.voltage.nominal (e.g.  24) if your device does not serve that either.

               Note
               Lead (PbAc) battery charge graph is not linear, so guesstimated charge value may not be perfectly
               accurate. However it should be good enough to determine battery actual status and roughly
               estimate the time it can still power the system.

               Warning
               This keyword may be deprecated in future releases of the driver, in favor of runtimecal and other
               settings which it requires (as seen in nutdrv_qx(8), blazer_ser(8) and blazer_usb(8) drivers).
