NAME

       powercom - 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, BNT-other and OPTI. 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.

nobt
If this flag is present, the battery check on startup is skipped. This is useful for
systems that tend to overload the UPS when testing the battery on system startup —
just when the power consumption tends to be high.

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.
