POWERCOM(8) Network UPS Tools (NUT) POWERCOM(8)NAMEpowercom - UPS driver for Powercom/Trust/Advice UPS equipment
NOTE
This man page only documents the hardware‐specific features of the pow‐
ercom driver. For information about the core driver, see nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports many similar kinds of UPS hardware. The most com‐
mon ones are the Trust 425/625, Powercom, and Advice Partner/King
PR750. Others using the same protocol may also work.
EXTRA ARGUMENTS
This driver supports the following optional settings in the
ups.conf(5):
linevoltage=value
An integer specifying the mains voltage. It can't be auto
detected. Acceptable values are in the range of 110‐120 or
220‐240. The default is 230.
manufacturer=name
Specify the manufacturer name, which also can't be auto
detected. This is a user defined string so any name is accept‐
able. The default is PowerCom.
modelname=name
Specify the model name, which also can't be auto detected. This
is a user defined string so any name is acceptable. The default
is Unknown.
serialnumber=value
Like modelname above, but for the serial number. The default is
Unknown.
type=name
The exact type of the communication protocol within the powercom
family, that will be used to communicate with the UPS. The type
is named after the first modelname that was coded with that pro‐
tocol. The acceptable names are KP625AP, Trust, Egys, KIN, BNT,
IMP and BNT-other. The default is Trust. BNT-other - it's a
special type for BNT 100-120V models for this type you can (I
think must!) specify voltage, batteryPercentage, loadPercentage
and validationSequence.
numOfBytesFromUPS=value
The number of bytes in a UPS frame. The default is type depen‐
dant and is given below.
methodOfFlowControl=name
The method of serial communication flow control that is engaged
by the UPS. The default is type dependant and is given below.
Acceptable names are dtr0rts1, dtr1 or no_flow_control.
shutdownArguments={{minutes,seconds},whether_minutes_should_be_used}
The minutes and seconds that the UPS should wait between receiv‐
ing the shutdown command and actually shutting off. The other
argument should be set to the character n only when the minutes
value should be skipped and not sent to the UPS. The default is
type dependant and is given below. The braces and commas are
mandatory. Note that there should be no white space characters.
voltage={coefficient1,coefficient2,coefficient3,coefficient4}
Only for KP625AP, Trust, Egys, BNT-other A quad that is used
convert the raw data to human readable voltage reading. The
default is type dependant and is given below. Do note that the
braces and commas are mandatory, as well as the lack of white
space characters.
frequency={coefficient1,coefficient2}
Only for KP625AP, Trust, Egys A pair to convert the raw data to
human readable frequency reading. The default is type dependant
and is given below. Do note that the braces and commas are
mandatory as well, as the lack of white space characters.
batteryPercentage={coefficient1,coefficient2,coefficient3,coeffi‐
cient4,coefficient5}
Only for KP625AP, Trust, Egys, BNT-other A 5 tuple to convert
the raw data to human readable battery percentage reading. The
default is type dependant and is given below. Do note that the
braces and commas are mandatory, as the lack of white space
characters.
loadPercentage={coefficient1,coefficient2,coefficient3,coefficient4}
Only for KP625AP, Trust, Egys, BNT-other A quad to convert the
raw data to human readable load percentage reading. The default
is type dependant and is given below. Do note that the braces
and commas are mandatory, as the lack of white space characters.
validationSequence={{index1,value1},{index2,value2},{index3,value3}}
Only for KP625AP, Trust, Egys, BNT-other 3 pairs to be used for
validating the UPS by comparing bytes of the raw data with con‐
stant values. The default is type dependant and is given below.
The braces and commas are mandatory, as the lack of white space
characters.
