.SH "NAME"
|
|
blazer_usb \- Driver for Megatec/Q1 protocol USB based UPS equipment
|
|
.SH "NOTE"
|
|
.sp
|
|
This man page only documents the hardware\-specific features of the blazer driver\&. For information about the core driver, see \fBnutupsdrv\fR(8)\&.
|
|
.SH "SUPPORTED HARDWARE"
|
|
.sp
|
|
The blazer driver is known to work with various UPSes from Blazer, Energy Sistem, Fenton Technologies, General Electric, Mustek 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\(cqt been tested\&.
|
|
.sp
|
|
All devices with a serial interface (use the \fBblazer_ser\fR driver) and many with a USB interface (use the \fBblazer_usb\fR driver) are supported\&.
|
|
.SH "EXTRA ARGUMENTS"
|
|
.sp
|
|
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 \fBups.conf\fR(5)):
|
|
.PP
|
|
\fBdefault\&.battery\&.voltage\&.high =\fR \fIvalue\fR
|
|
.RS 4
|
|
Maximum battery voltage that is reached after about 12 to 24 hours charging\&. If you want the driver to report a guesstimated
|
|
\fBbattery\&.charge\fR, you need to specify this (see
|
|
BATTERY CHARGE)\&.
|
|
.RE
|
|
.PP
|
|
\fBdefault\&.battery\&.voltage\&.low =\fR \fIvalue\fR
|
|
.RS 4
|
|
Minimum battery voltage just before the UPS automatically shuts down\&. If you want the driver to report a guesstimated
|
|
\fBbattery\&.charge\fR, you need to specify this (see
|
|
BATTERY CHARGE)\&.
|
|
.RE
|
|
.PP
|
|
\fBdefault\&.battery\&.voltage\&.nominal =\fR \fIvalue\fR, \fBoverride\&.battery\&.voltage\&.nominal =\fR \fIvalue\fR
|
|
.RS 4
|
|
Some devices show a wrong nominal battery voltage (or none at all), so you may need to override or set a default value\&.
|
|
.RE
|
|
.PP
|
|
\fBoverride\&.battery\&.packs =\fR \fIvalue\fR
|
|
.RS 4
|
|
Some devices report a part of the total battery voltage\&. For instance, if
|
|
\fBbattery\&.voltage\&.nominal\fR
|
|
is 24 V, but it reports a
|
|
\fBbattery\&.voltage\fR
|
|
of around 2 V, the number of
|
|
\fBbattery\&.packs\fR
|
|
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\&.
|
|
.RE
|
|
.PP
|
|
\fBondelay =\fR \fIvalue\fR
|
|
.RS 4
|
|
Time to wait before switching on the UPS (minutes)\&. Note that a value below 3 minutes, may cause earlier firmware versions to not switch on automatically, so it defaults to 3 minutes\&. The acceptable range is
|
|
0\&.\&.9999
|
|
minutes\&.
|
|
.RE
|
|
.PP
|
|
\fBoffdelay =\fR \fIvalue\fR
|
|
.RS 4
|
|
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\&. The acceptable range is
|
|
12\&.\&.600
|

seconds\&.

\fBruntimecal =\fR \fIvalue,value,value,value\fR
|
|
.RS 4
|
|
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
|
|
.sp
|
|
.if n \{\
|

.RS 4

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\(cqt get too close to no load (prediction of runtime depends more on idle load for the battery then)\&.

Due to popular demand, this driver will report a guesstimated \fBbattery\&.charge\fR and optionally \fBbattery\&.runtime\fR, provided you specified a couple of the EXTRA ARGUMENTS listed above\&.
|
|
.sp
|
|
If you specify both \fBbattery\&.voltage\&.high\fR and \fBbattery\&.voltage\&.low\fR in \fBups.conf\fR(5), but don\(cqt enter \fBruntimecal\fR, 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\(cqt practical if the power went out and the UPS is providing power for your systems\&.
|

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 \fBruntimecal\fR, 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\(cqt work\&.
|
|
.sp
|
|
The driver also has no way of determining the degradation of the battery capacity over time, so you\(cqll have to deal with this yourself (by adjusting the values in \fBruntimecal\fR)\&. 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\&.
|
|
.sp
|
|
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 \fBups.conf\fR(5), so don\(cqt complain with the author\&. If you need something better, buy a UPS that reports \fBbattery\&.charge\fR and \fBbattery\&.runtime\fR all by itself without the help of a NUT driver\&.

Some UPS commands aren\(cqt 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\(cqt even provide a way for the driver to check for this, so the unsupported commands will silently fail\&.
|
|
.sp

Both the \fBload\&.off\fR and \fBshutdown\&.stayoff\fR instant commands are meant to turn the load off indefinitely\&. However, some UPS models don\(cqt allow this\&.

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