NAME

tripplite_usb - Driver for older Tripp Lite USB UPSes (not PDC HID)

SYNOPSIS

tripplite_usb -h

tripplite_usb -a UPS_NAME [OPTIONS]

SUPPORTED HARDWARE

This driver should work with older Tripp Lite UPSes which are detected as USB HID-class devices, but are not true HID Power-Device Class devices. So far, the devices supported by tripplite_usb have product ID 0001, and the newer units (such as those with "LCD" in the model name) with product ID 2001 require the usbhid-ups(8) driver instead. Please report success or failure to the nut-upsuser mailing list. A key piece of information is the protocol number, returned in ups.firmware.aux. Also, be sure to turn on debugging (-DDD) for more informative log messages. If your Tripp Lite UPS uses a serial port, you may wish to investigate the tripplite(8) or tripplitesu(8) driver.

This driver has been tested with the following models:

  • INTERNETOFFICE700

  • OMNIVS1000

  • OMNIVS1500XL (some warnings)

  • SMART700USB

  • SMART1500RM2U

  • SMART2200RMXL2U

  • SMART3000RM2U

If you have used Tripp Lite’s PowerAlert software to connect to your UPS, there is a good chance that tripplite_usb will work if it uses one of the following protocols:

  • Protocol 0004

  • Protocol 1001

  • Protocol 2001

  • Protocol 3003

  • Protocol 3005

On the other hand, if the web page for your UPS on the Tripp-Lite website says "HID-compliant USB port also enables direct integration with built-in power management and auto-shutdown features of Windows and MAC OS X", then you should use the usbhid-ups(8) driver instead.

EXTRA ARGUMENTS

This driver supports the following optional settings in the ups.conf(5) file (or with -x on the command line):

offdelay

This setting controls the delay between receiving the "kill" command (-k) and actually cutting power to the computer.

battery_min, battery_max

These floating-point values correspond to the "empty" (10%) and "full" (100%) voltages of the battery. They are used for an approximation of the battery state-of-charge. The calculated battery.charge value will be clamped to the range of 10% through 100%, so the resting voltage of the charged battery can be used for battery_max, and the higher float charge voltage should not cause problems.

bus

This regular expression is used to match the USB bus (as seen in /proc/bus/usb/devices or lsusb(8); including leading zeroes).

device

This regular expression is used to match the USB device (as seen in /proc/bus/usb/devices or lsusb(8); including leading zeroes). Note that device numbers are not guaranteed by the OS to be stable across re-boots or device re-plugging.

product

A regular expression to match the product string for the UPS. This would be useful if you have two different Tripp Lite UPS models connected to the system, and you want to be sure that you shut them down in the correct order.

Note
 This regex is matched against the full USB product string as seen in lsusb(8). The ups.model in the upsc(1) output only lists the name after TRIPP LITE, so to match a SMART2200RMXL2U, you could use the regex .*SMART2200.*.
productid

The productid is a regular expression which matches the UPS PID as four hexadecimal digits. So far, the only devices that work with this driver have PID 0001.

serial

It does not appear that these particular Tripp Lite UPSes use the iSerial descriptor field to return a serial number. However, in case your unit does, you may specify it here.

For more information on regular expressions, see regex(7)

RUNTIME VARIABLES

ups.delay.shutdown

This variable is the same as the offdelay setting, but it can be changed at runtime by upsrw(8).

ups.id

Some SMARTPRO models feature an ID that can be set and retrieved. If your UPS supports this feature, this variable will be listed in the output of upsrw(8).

outlet.1.switch

Some Tripp Lite units have a switchable outlet (usually outlet #1) which can be turned on and off by writing 1 or 0, respectively, to outlet.1.switch with upsrw(8). If your unit has multiple switchable outlets, substitute the outlet number for 1 in the variable name. Be sure to test this first - there is no other way to be certain that the number used by the driver matches the label on the unit.

KNOWN ISSUES AND BUGS

The driver was not developed with any official documentation from Tripp Lite, so certain events may confuse the driver. If you observe any strange behavior, please re-run the driver with -DDD to increase the verbosity.

So far, the Tripp Lite UPSes do not seem to have a serial number or other globally unique identifier accessible through USB. Thus, when monitoring several Tripp Lite USB UPSes, you should use either the bus, device or product configuration options to uniquely specify which UPS a given driver instance should control.

For instance, you can easily monitor an OMNIVS1000 and a SMART1500RM2U at the same time, since they have different USB Product ID strings. If you have two SMART1500RM2U units, you would have to find which USB bus and device number each unit is on (via lsusb(8)).

Some of the SMART*2U models have an ID number, but because this ID is not exposed as a USB string descriptor, there is no easy way to use this ID to distinguish between multiple UPS units on a single machine. The UPS would need to be claimed by the driver in order to read this ID.
