NAME

       metasys - Driver for Meta System UPS equipment

NOTE

       This man page only documents the hardware-specific features of the metasys driver. For information about the core driver, see nutupsdrv(8).

SUPPORTED HARDWARE

       The metasys driver was written with the "Meta System UPS Protocol Rev.1.12" kindly supplied from Meta System.

       The driver should support all the common features of the ups models:

       o   HF Line (/2) 1-8 boards

       o   HF Millennium (810, 820)

       o   HF TOP Line (910, 920, 930, 940, 950, 970, 980)

       o   ECO Network (750, 1000, 1050, 1500, 1800, 2000, 2100, 2500, 3000)

       o   ECO (305, 308, 311, 511, 516, 519, 522, SX, SXI)

       o   ally HF (800, 1000, 1250, 1600, 2000, 2500)

       o   Megaline (1250, 2500, 3750, 5000, 6250, 7500, 8750, 10000)

CABLING

       The needed cable is a standard pin-to-pin serial cable with at least pins 2, 3, and 5 (on DB9 connector) connected.

EXTRA ARGUMENTS

       This driver supports no extra arguments from ups.conf(5).

BUGS

       This driver has been tested on Meta System HF Millennium 820 and ally HF 1000 only.

       Any information about the use of the driver with the other listed UPS are really welcome.
