NAME

       nutdrv_qx - Driver for Q* protocol serial and USB based UPS equipment

NOTE

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

SUPPORTED HARDWARE

       The nutdrv_qx driver is known to work with various UPSes from Blazer, Energy Sistem, Fenton Technologies,
       General Electric, Mustek, Voltronic Power (rebranded by many, many - have I said many? - others.. Long
       story short: if your UPS came with a software called Viewpower, chances are high that it works with this
       driver with one of the voltronic* protocols or with the mecer one) and many others.

       The NUT compatibility table lists all the known supported models. Keep in mind, however, that other
       models not listed there may also be supported, but haven’t been tested.

       All devices with a serial interface and many with a USB interface are supported.

EXTRA ARGUMENTS

       You may need to override or provide defaults for some values, depending on the make and model of your
       UPS.

       The following are the ones that most likely will need changing (see ups.conf(5)):

       ondelay = value
           Time to wait before switching on the UPS (seconds). This value is truncated to units of 60 seconds.

           Note that a value below 3 minutes, may cause earlier firmware versions to not switch on
           automatically, so it defaults to 3 minutes (i.e. 180 seconds).

           This option provides a default value for ups.delay.start that will then be used by the driver in the
           automatic shutdown sequence (i.e. calling the driver with the -k option, calling upsdrvctl(8) with
           the shutdown option or when the FSD flag is set and upsmon(8) enters its shutdown sequence): however
           you can change this value ‘on the fly’ for the actual session, only for the use with instant
           commands, setting ups.delay.start with upsrw(8).

       offdelay = value
           Time to wait before shutting down the UPS (seconds). This value is truncated to units of 6 seconds
           (less than 60 seconds) or 60 seconds (more than 60 seconds). Defaults to 30 seconds.

           This option provides a default value for ups.delay.shutdown that will then be used by the driver in
           the automatic shutdown sequence (i.e. calling the driver with the -k option, calling upsdrvctl(8)
           with the shutdown option or when the FSD flag is set and upsmon(8) enters its shutdown sequence):
           however you can change this value ‘on the fly’ for the actual session, only for the use with instant
           commands, setting ups.delay.shutdown with upsrw(8).

       stayoff
           If you set stayoff in ups.conf(5) when FSD arises the UPS will call a shutdown.stayoff shutting down
           after ups.delay.shutdown seconds and won’t return (see KNOWN PROBLEMS), otherwise (standard
           behaviour) the UPS will call shutdown.return shutting down after ups.delay.shutdown seconds and then
           turn on after ups.delay.start seconds (if mains meanwhile returned).

       protocol = string
           Skip autodetection of the protocol to use and only use the one specified. Supported values: bestups,
           mecer, megatec, megatec/old, mustek, q1, voltronic, voltronic-qs, voltronic-qs-hex and zinto.

           Note that if you end up using the q1 protocol, you may want to give a try to the mecer, megatec and
           zinto ones setting the novendor/norating flags (only one, or both).

       pollfreq = value
           Set polling frequency, in seconds, to reduce the data flow. Between two polling requests the driver
           will do ‘quick polls’ dealing just with ups.status. The default value is 30 (in seconds).

       If your UPS doesn’t report either battery.charge or battery.runtime you may want to add the following
       ones in order to have guesstimated values:

       default.battery.voltage.high = value
           Maximum battery voltage that is reached after about 12 to 24 hours charging. If you want the driver
           to report a guesstimated battery.charge, you need to specify this (see BATTERY CHARGE).

       default.battery.voltage.low = value
           Minimum battery voltage just before the UPS automatically shuts down. If you want the driver to
           report a guesstimated battery.charge, you need to specify this (see BATTERY CHARGE).

       default.battery.voltage.nominal = value, override.battery.voltage.nominal = value
           Some devices show a wrong nominal battery voltage (or none at all), so you may need to override or
           set a default value.

       override.battery.packs = value
           Some devices report a part of the total battery voltage. For instance, if battery.voltage.nominal is
           24 V, but it reports a battery.voltage of around 2 V, the number of battery.packs to correct this
           reading would be 12. The driver will attempt to detect this automatically, but if this fails somehow,
           you may want to override this value.

       runtimecal = value,value,value,value
           Parameter used in the (optional) runtime estimation. This takes two runtimes at different loads.
           Typically, this uses the runtime at full load and the runtime at half load. For instance, if your UPS
           has a rated runtime of 240 seconds at full load and 720 seconds at half load, you would enter

               runtimecal = 240,100,720,50

           The first load should always be higher than the second. If you have values available for loads other
           than 100 and 50 % respectively, you can use those too, but keep them spaced apart as far as
           reasonably possible. Just don’t get too close to no load (prediction of runtime depends more on idle
           load for the battery then).

       chargetime = value
           The time needed to fully recharge the battery after being fully discharged. If not specified, the
           driver defaults to 43200 seconds (12 hours). Only used if runtimecal is also specified.

       idleload = value
           Minimum battery load used by the driver to estimate the runtime. If not specified, the driver
           defaults to 10%. Only used if runtimecal is also specified.

   BESTUPS, MECER, MEGATAEC, MEGATEC/OLD, MUSTEK, Q1, VOLTRONIC-QS, VOLTRONIC-QS-HEX, ZINTO PROTOCOLS
       ignoresab
           Some UPSes incorrectly report the ‘Shutdown Active’ bit as always on, consequently making the driver
           believe the UPS is nearing a shutdown (and, as a result, ups.status always contains FSD... and you
           know what this means). Setting this flag will make the driver ignore the ‘Shutdown Active’ bit.

   MECER, MEGATAEC, MEGATEC/OLD, MUSTEK, ZINTO PROTOCOLS
       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..600 seconds.

       norating
           Some UPSes will lock up if you attempt to read rating information from them. Setting this flag will
           make the driver skip this step.

       novendor
           Some UPSes will lock up if you attempt to read vendor information from them. Setting this flag will
           make the driver skip this step.

   BESTUPS PROTOCOL
       ondelay
           The acceptable range is 60..599940 seconds.

       offdelay
           The acceptable range is 12..5940 seconds.

       pins_shutdown_mode = value
           Set shutdown mode functionality of Pin 1 and Pin 7 on the UPS DB9 communication port (Per Best
           Power’s EPS-0059) to value [0..6].

   Q1 PROTOCOL
       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..600 seconds.

   VOLTRONIC-QS, VOLTRONIC-QS-HEX PROTOCOLS
       ondelay
           The acceptable range is 60..599940 seconds.

       offdelay
           The acceptable range is 12..540 seconds.

   VOLTRONIC PROTOCOL
       The following options are supported only by the voltronic protocol. Not all of them are available on all
       the UPSes supported by this protocol.

       ondelay
           The acceptable range is 0..599940 seconds.

       offdelay
           The acceptable range is 12..5940 seconds.

       battery_number = value
           Set number of batteries that make a pack to value [1..9]. This setting will change the charge and
           runtime estimation reported by the UPS.

       output_phase_angle = value
           Changes output phase angle to the provided value [000, 120, 180, 240]°.

       UPS CAPABILITY SETTINGS
           reset_to_default
               Reset capability options and their voltage and frequency limits to safe default values. (Doable
               only when the UPS is in Standby Mode)

               Note that setting this option will reset also ups.start.auto, battery.protection,
               battery.energysave, ups.start.battery, outlet.0.switchable, input.transfer.high,
               input.transfer.low, input.frequency.high and input.frequency.low.

           These UPSes can be fine-tuned to suit your needs enabling or disabling the following options (the
           driver should tell you which one the UPS is capable of on startup: the settable ones will be reported
           either ar enabled or disabled in the logs):

           alarm_control = string
               Enable or disable alarm (BEEP!) [enabled/disabled]. Settable also ‘on the fly’ with beeper.enable
               and beeper.disable instant commands.

           bypass_alarm = string
               Enable or disable alarm (BEEP!) at Bypass Mode [enabled/disabled].

           battery_alarm = string
               Enable or disable alarm (BEEP!) at Battery Mode [enabled/disabled].

           bypass_when_off = string
               Enable or disable bypass when the UPS is Off [enabled/disabled]. If enabled, AC will directly
               provide power to connected devices when the UPS is off.

           bypass_forbidding = string
               Enable or disable Bypass Forbidding [enabled/disabled]. If enabled, the UPS will not transfer to
               bypass mode under any condition.

           converter_mode = string
               Enable or disable Converter Mode [enabled/disabled]. When input frequency is within 40 Hz to 70
               Hz, the UPS can be set at a constant output frequency, 50 Hz or 60 Hz. The UPS will still charge
               battery under this mode.

           eco_mode = string
               Enable or disable ECO Mode [enabled/disabled]. When input voltage/frequency are within acceptable
               range, the UPS will bypass voltage to output for energy saving. PFC and INVERTER are still active
               at this mode. Settable also ‘on the fly’ with bypass.start and bypass.stop instant commands.

           advanced_eco_mode = string
               Enable or disable Advanced ECO Mode [enabled/disabled]. When input voltage/frequency are within
               acceptable range, the UPS will bypass voltage to output for energy saving. PFC and INVERTER are
               off at this mode.

           battery_open_status_check = string
               Enable or disable Battery Open Status Check [enabled/disabled]. If enabled, when the UPS is
               turned on, it will check if the battery is connected or not.

           site_fault_detection = string
               Enable or disable site fault detection [enabled/disabled]. If enabled, the UPS will beep when the
               input neutral and hot wires are reversed.

           constant_phase_angle = string
               Enable or disable Constant Phase Angle Function (output and input phase angles are not equal)
               [enabled/disabled].

           limited_runtime_on_battery = string
               Enable or disable limited runtime on battery mode [enabled/disabled].

       BYPASS MODE VOLTAGE/FREQUENCY LIMITS
           Variables to fine-tune voltage and frequency limits for Bypass mode. These limits are reset to safe
           default values by reset_to_default.

           If AC voltage and frequency are within acceptable range, Bypass mode will be used (If the UPS is
           capable of and it’s enabled).

           Since these values are device-specific, if your UPS support them, you will get their settable limits
           printed in the logs on startup.

           max_bypass_volt = value
               Maximum voltage for Bypass Mode (V).

           min_bypass_volt = value
               Minimum voltage for Bypass Mode (V).

           max_bypass_freq = value
               Maximum frequency for Bypass Mode (Hz).

           min_bypass_freq = value
               Minimum frequency for Bypass Mode (Hz).

       OPTIONS SPECIFIC FOR P31 UPSES
           The following options are available only on P31 UPSes.

           work_range_type = string
               Device grid working range for P31 UPSes [Appliance/UPS].

       TESTING
           This protocol comes with a couple of functions that are not enabled by default because of the lack of
           knowledge of some part of the communication protocol used by these UPSes by your friendly
           neighborhood developer. Since these functions are supposed to be queries to the UPS for some kind of
           informations, they should not make your UPS go boom. So if you are brave enough to risk your UPS and
           attached devices' life to help the developers, this will be very appreciated.. Do it at your own
           risk.

           testing
               If invoked the driver will exec also commands that still need testing.

   SERIAL INTERFACE ONLY
       cablepower = string
           By default the driver will set DTR and clear RTS (normal). If you find that your UPS isn’t detected
           or the communication with the UPS is unreliable, you may try if clear DTR and set RTS (reverse), set
           DTR and RTS (both) or clear DTR and RTS (none) improves this situation.

   USB INTERFACE ONLY
       port = string
           You must set value to auto.

       vendorid = regex, productid = regex, vendor = regex, product = regex, serial = regex
           Select a specific UPS, in case there is more than one connected via USB. Each option specifies an
           extended regular expression (see regex(7)) that must match the UPS’s entire vendor/product/serial
           string (minus any surrounding whitespace), or the whole 4-digit hexadecimal code for vendorid and
           productid. Try -DD for finding out the strings to match.

           Examples:

           •   -x vendor="Foo.Corporation.*"

           •   -x vendorid=051d* (APC)

           •   -x product=".*(Smart|Back)-?UPS.*"

       bus = regex
           Select a UPS on a specific USB bus or group of busses. The argument is a regular expression that must
           match the bus name where the UPS is connected (e.g.  bus="002", bus="00[2-3]").

       subdriver = string
           Select a serial-over-USB subdriver to use. You have a choice between cypress, fabula, fuji, ippon,
           krauler, phoenix and sgs. When using this option, it is mandatory to also specify the vendorid and
           productid.

       langid_fix = value
           Apply the language ID workaround to the krauler subdriver. This is mandatory for some devices to work
           (LDLC, Dynamix and others). You must provide value (0x409 or 0x4095), according to your device entry
           in NUT hardware compatibility list (HCL).

       IMPLEMENTATION NOTES
           fabula subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the various
               test.battery commands. Plus, the shutdown.return command ignores the values set in
               ups.delay.start/ondelay and makes the UPS turn on the load as soon as power is back.

           fuji subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the shutdown.stayoff
               and load.off commands. Plus, the shutdown.return command ignores the values set in
               ups.delay.start/ondelay and makes the UPS turn on the load as soon as power is back.

           krauler subdriver
               This subdriver, meant to be used with the megatec protocol, does not support the shutdown
               commands, i.e.: shutdown.return, shutdown.stayoff and load.off.

BATTERY CHARGE

       Due to popular demand, this driver will report a guesstimated battery.charge and optionally
       battery.runtime, provided you specified a couple of the EXTRA ARGUMENTS listed above.

       If you specify both battery.voltage.high and battery.voltage.low in ups.conf(5), but don’t enter
       runtimecal, it will guesstimate the state of charge by looking at the battery voltage alone. This is not
       reliable under load, as this only gives reasonably accurate readings if you disconnect the load, let the
       battery rest for a couple of minutes and then measure the open cell voltage. This just isn’t practical if
       the power went out and the UPS is providing power for your systems.

                                battery.voltage - battery.voltage.low
           battery.charge =  ------------------------------------------ x 100 %
                             battery.voltage.high - battery.voltage.low

       There is a way to get better readings without disconnecting the load but this requires one to keep track
       on how much (and how fast) current is going in and out of the battery. If you specified the runtimecal,
       the driver will attempt to do this. Note however, that this heavily relies on the values you enter and
       that the UPS must be able to report the load as well. There are quite a couple of devices that report 0 %
       (or any other fixed value) at all times, in which case this obviously doesn’t work.

       The driver also has no way of determining the degradation of the battery capacity over time, so you’ll
       have to deal with this yourself (by adjusting the values in runtimecal). Also note that the driver
       guesses the initial state of charge based on the battery voltage, so this may be less than 100 %, even
       when you are certain that they are full. There is just no way to reliably measure this between 0 and 100
       % full charge.

       This is better than nothing (but not by much). If any of the above calculations is giving you incorrect
       readings, you are the one that put in the values in ups.conf(5), so don’t complain with the author. If
       you need something better, buy a UPS that reports battery.charge and battery.runtime all by itself
       without the help of a NUT driver.

NOTES FOR THE PREVIOUS USER OF MEGATEC DRIVERS

       The nutdrv_qx driver having replaced the megatec ones, some configuration changes may be required by
       users switching to nutdrv_qx.

       Part of this, the following megatec options, in ups.conf(5), have to be changed:

       battvolts
           You need to use default.battery.voltage.high and default.battery.voltage.low

       dtr and rts
           You need to use cablepower

       ignoreoff
           This parameter can simply be discarded, since it was a wrong understanding of the specification.

NOTES FOR THE PREVIOUS USER OF BLAZER DRIVERS

       The nutdrv_qx driver having replaced the blazer ones, some configuration changes may be required by users
       switching to nutdrv_qx.

       Part of this, the following blazer options, in ups.conf(5), have to be changed:

       ondelay
           While the previous blazer drivers expected minutes, the new nutdrv_qx driver wants seconds.

       The following instant command has also been changed:

       test.battery.start value
           While the old blazer drivers expected a value in minutes, the nutdrv_qx driver wants a value in
           seconds.

NOTES FOR THE PREVIOUS USER OF BESTUPS DRIVER

       The nutdrv_qx driver having replaced the bestups one, some configuration changes may be required by users
       switching to nutdrv_qx.

       Part of this, the following bestups options, in ups.conf(5), are no longer supported by this driver:

       nombattvolt, battvoltmult
           See BATTERY CHARGE.

       ID
           Discarded.

NOTES FOR THE PREVIOUS USER OF VOLTRONIC DRIVERS

       The nutdrv_qx driver having replaced the voltronic ones, some configuration changes may be required by
       users switching to nutdrv_qx.

       Part of this, the following voltronic options, in ups.conf(5), have to be changed:

       ondelay
           While the previous voltronic drivers expected minutes, the new nutdrv_qx driver wants seconds. It no
           longer defaults to 0 minutes but to 3 minutes (i.e. 180 seconds) for compatibility with the users
           switching from the old blazer drivers.

       battnumb
           This option has been renamed to battery_number.

       The following options are no longer supported by this driver, you can now change them more conveniently
       ‘on the fly’ calling upsrw(8) with the appropriate NUT variable - provided that your UPS supports them.

       battpacksbattery.packs

                            Set number of battery packs in
                            parallel [1..99]. This setting will
                            change the charge and runtime
                            estimation reported by the UPS.

       battlowbattery.voltage.low

                            Set minimum battery voltage just
                            before the UPS automatically shuts
                            down. This setting will change the
                            charge and runtime estimation
                            reported by the UPS.

                            function [enabled/disabled]. If
                            enabled, for energy saving, the UPS
                            will auto off when there is no load.

       cold_startups.start.battery

                            Enable or disable Cold Start
                            [enabled/disabled]. If enabled, the
                            UPS can be turned on also if AC is
                            not connected to the UPS.

       outlet_controloutlet.0.switchable

                            Enable or disable programmable
                            outlets control at battery mode
                            [enabled/disabled]. If enabled, the
                            UPS will cut off programmable outlets
                            after backup time (set through
                            outlet.{1,2,3,4}.delay.shutdown)
                            arrives. If disabled, the UPS will
                            provide continuous power to
                            programmable outlets until the
                            battery is running out.

KNOWN PROBLEMS

       Some UPS commands aren’t supported by all models. In most cases, the driver will send a message to the
       system log when the user tries to execute an unsupported command. Unfortunately, some models don’t even
       provide a way for the driver to check for this, so the unsupported commands will silently fail.

       Both the load.off and shutdown.stayoff instant commands are meant to turn the load off indefinitely.
       However, some UPS models don’t allow this.

       Some models report a bogus value for the beeper status (will always be enabled or disabled). So, the
       beeper.toggle command may appear to have no effect in the status reported by the driver when, in fact, it
       is working fine.

       The temperature and load value is known to be bogus in some models.

   VOLTRONIC-QS UNITS
       Both load.off and shutdown.stayoff instant commands are known to work as expected (i.e. turn the load off
       indefinitely) only if mains is present, otherwise, as soon as mains returns the load will be powered.

       After issuing a shutdown.return instant command, the UPS won’t wait ondelay before powering on the load,
       provided the following conditions are met:

       •   if the load has been previously (no matter how long before) powered off through
           load.off/shutdown.stayoffand powered on through load.on/shutdown.stopand

       •   if AC wasn’t cut after issuing the load.off/shutdown.stayoff (i.e. the UPS didn’t turn itself off)
           and

       •   if there’s a power outage after issuing the shutdown.return command

       In this case, as soon as mains returns the load will be powered.

   VOLTRONIC-QS-HEX UNITS
       shutdown.return, load.off, and shutdown.stayoff instant commands are known to work as expected only if
       mains is present, otherwise, as soon as mains returns the load will be powered.

UPS WARNINGS (VOLTRONIC PROTOCOL)

       The UPSes supported by voltronic protocol report warnings through a 64bit flag (bit1bit2...bit63bit64)
       where 1 means that a warning arose, while 0 means no warning. Since more than one warning at a time can
       be signaled, and because of the limited space in the ups.alarm variable, if the length of the warnings
       exceeds that of ups.alarms variable, they will be reported as bits. If you want to know the explanation
       of that bit you can either watch the log or see the next table (unlisted bits equal to unknown warnings).
