APCSMART-OLD(8)                   NUT Manual                   APCSMART-OLD(8)



NAME
       apcsmart-old - Driver for American Power Conversion Smart Protocol UPS
       equipment

SYNOPSIS
       apcsmart-old -h

       apcsmart-old -a UPS_NAME [OPTIONS]

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

SUPPORTED HARDWARE
       apcsmart-old should recognize all recent APC models that use a serial
       protocol at 2400 bps. This is primarily the Smart-UPS, Matrix-UPS and
       Back-UPS Pro lines.

       The driver attempts to support every bell and whistle of the APC
       reporting interface, whether or not this is strictly sensible.

       Some older hardware may only report a handful of variables. This is
       usually not a bug--they just don't support anything else.

CABLING
       This driver expects to see a 940-0024C cable or a clone by default. You
       can switch to the 940-0095B dual-mode cable support with the cable=
       definition described below.

       If your 940-0024C cable is broken or missing, use this diagram to build
       a clone:

EXTRA ARGUMENTS
       This driver supports the following optional settings in the
       ups.conf(5):

       cable=940-0095B
           Configure the serial port for the APC 940-0095B dual-mode cable.

       sdtype=num
           Use shutdown type num, according to this table:

           0
               soft shutdown or powerdown, depending on battery status

           1
               soft shutdown followed by powerdown

           2
               instant power off

           3
               power off with grace period

           4
               "force OB" hack method for CS 350

       Modes 0 and 1 will power up the load when power returns. Modes 2 and 3
       will keep the load turned off when the power returns.

       Mode 4 exploits an oddity in the CS 350 models since they only seem to
       support the S command, but then only when running on battery. As a
       result, the driver will force the UPS to go on battery if necessary
       before sending the shutdown command. This ensures that the load gets
       reset.

BUGS
       Some older APC UPS models return bogus data in the status register
       during a front panel test. This is usually detected and discarded, but
       some other unexpected values have occasionally slipped through.

       APC UPS models with both USB and serial ports require a power cycle
       when switching from USB communication to serial, and perhaps vice
       versa.

AUTHOR
       Nigel Metheringham <Nigel.Metheringham@Intechnology.co.uk> (drawing
       heavily on the original apcsmart driver by Russell Kroll). This driver
       was called newapc for a time and was renamed in the 1.5 series. In
       2.6.2 the driver was renamed to apcsmart-old, being superseded by
       updated version with new features.
