apcsmart - Driver for American Power Conversion Smart Protocol UPS equipment
This man page only documents the hardware-specific features of the apcsmart driver. For
information about the core driver, see nutupsdrv(8).
apcsmart should recognize all APC models that use a serial protocol at 2400 bps. This is
primarily the Smart-UPS and Matrix-UPS lines, but some Back-UPS Pro models are also sup-
Some older hardware may only report a handful of variables. This is usually not a bug -
they just don't support anything else.
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:
This driver supports the following optional settings in the ups.conf(5):
Configure the serial port for the APC 940-0095B dual-mode cable.
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
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.
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 occa-
sionally slipped through.
