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.
UPS COMMANDS

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.
battpacks → battery.packs
Set number of battery packs in
parallel [1..99]. This setting
will change the charge and
runtime estimation reported by
the UPS.
battlow → battery.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.
auto_reboot → ups.start.auto
Enable or disable auto reboot
[enabled/disabled]. If enabled,
the UPS will auto recover when
AC power returns.
battery_protection → battery.protection
Enable or disable battery deep
discharge protection
[enabled/disabled].
energy_saving → battery.energysave
Enable or disable Green power
function [enabled/disabled]. If
enabled, for energy saving, the
UPS will auto off when there is
no load.
cold_start → ups.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_control → outlet.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.
max_eco_volt → input.transfer.high
Maximum voltage for ECO Mode
(V). If AC voltage is within
acceptable range, ECO mode will
be used (If the UPS is capable
of and it’s enabled).
min_eco_volt → input.transfer.low
Minimum voltage for ECO Mode
(V). If AC voltage is within
acceptable range, ECO mode will
be used (If the UPS is capable
of and it’s enabled).
max_eco_freq → input.frequency.high
Maximum frequency for ECO Mode
(Hz). If AC frequency is within
acceptable range, ECO mode will
be used (If the UPS is capable
of and it’s enabled).
min_eco_freq → input.frequency.low
Minimum frequency for ECO Mode
(Hz). If AC frequency is within
acceptable range, ECO mode will
be used (If the UPS is capable
of and it’s enabled).
outlet1_delay → outlet.1.delay.shutdown
Delay time before programmable
outlet 1 shuts down the load
when on battery mode [0..59940]
(seconds).
outlet2_delay → outlet.2.delay.shutdown
Delay time before programmable
outlet 2 shuts down the load
when on battery mode [0..59940]
(seconds).
outlet3_delay → outlet.3.delay.shutdown
Delay time before programmable
outlet 3 shuts down the load
when on battery mode [0..59940]
(seconds).
outlet4_delay → outlet.4.delay.shutdown
Delay time before programmable
outlet 4 shuts down the load
when on battery mode [0..59940]
(seconds).
batt_type → battery.type
Battery type (for P31 UPSes
only) [Li/Flooded/AGM].
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).
