POWERCOM(8) NUT Manual POWERCOM(8)NAMEpowercom - UPS driver for serial Powercom/Trust/Advice UPS equipment
NOTE
This man page only documents the hardware-specific features of the
powercom driver. For information about the core driver, see
nutupsdrv(8).
SUPPORTED HARDWARE
This driver supports many similar kinds of serial UPS hardware (as well
as a few USB UPS models with USB-to-serial adapters). The most common
ones are the Trust 425/625, Powercom, and Advice Partner/King PR750.
Others using the same protocol may also work. For USB connections, you
might need usbhid-ups(8).
For more specific guidance on which driver is applicable for a USB
connection, see the NUT Hardware Compatibility List (HCL).
EXTRA ARGUMENTS
This driver supports the following optional settings in the ups.conf(5)
file:
linevoltage=value
An integer specifying the line 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 acceptable. 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 protocol.
The acceptable names are Trust, Egys, KP625AP, IMP, KIN, BNT, and
BNT-other. The default is Trust.
BNT-other is a special type for other BNT models (such as the 1500A
at 120V and can be used to override ALL models using ALL of the
following values.
shutdownArguments={{minutes,seconds},whether_minutes_should_be_used}
The minutes and seconds that the UPS should wait between receiving
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-dependent
and is given below. The braces and commas are mandatory. Note that
there should be no whitespace characters.
numOfBytesFromUPS=value
The number of bytes in a UPS frame: 16 is common, 11 for Trust. The
default is type-dependent and is given below.
methodOfFlowControl=name
The method of serial communication flow control that is engaged by
the UPS. The default is type-dependent and is given below.
Acceptable names are dtr0rts1, dtr1 or no_flow_control.
validationSequence={{index1,value1},{index2,value2},{index3,value3}}
(Only for types KP625AP, Trust, Egys.) 3 pairs to be used for
validating the UPS by comparing bytes of the raw data with constant
values. The index selects the byte from the UPS (see
numOfBytesFromUPS) and the value is for matching to the byte. The
default is type-dependent and is given below. The braces and commas
are mandatory, as the lack of white space characters.
frequency={A,B}
(Only for types KP625AP, Trust, Egys.) A pair to convert the raw
frequency data to a human-readable frequency reading using the
function 1/(A*x+B). If the raw value x IS the frequency, then set
A=1/(x^2) and B=0. The default is type-dependent and is given
below. Do note that the braces and commas are mandatory as well, as
the lack of whitespace characters.
loadPercentage={BatteryA,BatteryB,LineA,LineB}
(Only for types KP625AP, Trust, Egys.) A quad to convert the raw
load data to human readable load percentage reading using the
function A*x+B. If the raw value x IS the Load Percent, then set
A=1 and B=0. The default is type-dependent and is given below. Do
note that the braces and commas are mandatory, as the lack of white
space characters.
batteryPercentage={Battery1,Battery2,Battery3,Line4,Line5}
(Only for KP625AP, Trust, Egys.) A 5 tuple to convert the raw
battery and line data to a human-readable battery and line
percentage reading using the functions (Battery) A*x+B*y+C and
(Line) D*x+E. If the raw value x IS the Battery Percent, then set
A=1, B=0, C=0, D=1, E=0. The default is type-dependent and is given
below. Do note that the braces and commas are mandatory, as the
lack of white space characters.
voltage={240A,240B,120A,120B}
(Only for types KP625AP, Trust, Egys.) A quad that is used convert
the raw voltage data to a human-readable voltage reading using the
function A*x+B. If the raw value x IS HALF the Voltage, then set
A=2, B=0. The default is type-dependent and is given below. Do note
that the braces and commas are mandatory, as well as the lack of
whitespace characters.
DEFAULT VALUES FOR THE EXTRA ARGUMENTS
linevoltage = 230
manufacturer = PowerCom
modelname = Unknown
serialnumber = Unknown
type = Trust
The rest of the default values for the extra arguments are
type-dependent. However, BNT-other is a special type that can be used
to override ALL values for ALL models.
