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).
