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.

AUTHORS AND HISTORY

       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.
