Apcupsd User's Manual Release Notes This release contains a good number of cleanups and bug xes to prior 3.10.x versions, and is intended to be the ocial release. See the ChangeLog below for more details. New Features - Implement USB on all *BSD systems. Note, the kernel drivers on most of these systems are still fragile. There are known problems, for example, on FreeBSD. - Fix killpower on USB UPSes to properly turn off UPS. - More killpower fixes for BackUPS Pros. - Fix killpower sequence fo

page. Change Log for older versions ----> Release 3.10.16 04Nov04 - Adam has fixed the killpower problem for USB so that the USB now properly turns off the power. Nice job. - Converted manual from docbook to texinfo format. There is some cleanup to be done, but we get an index. - Thanks to Adam for converting the .png images to .pdf - Apply patch to fix aastr... supplied by Manfred Schwarb. - Changed Solaris to use mailx by default at the suggestion of Neil Brookins. - Added Adam's snoopdecode.c

- ifdef code in apcaccess that tries to write in the shared memory buffer. - Applied Adam's patch for fixing the pthreads dependencies in asys.c - Tweak the patch a bit hopefully so that OpenBSD will work. - Made a sweep through quite a few files updating the copyright, eliminating the disclaimer (now in DISCLAIMER), and adding as many astrncpy() and astrncat()s as I could find. There still remain some drivers and the cgi code to do. - Implemented true/false and bool. Started implementing it in

How To Use This Manual This is the manual for apcupsd, a daemon for communicating with UPSes (Uninterruptible Power Supplies) made by American Power Corporation (APC). If you have an APC-made UPS, whether sold under the APC name- plate or OEMed (The HP PowerTrust 2997A UPS has been tested as a \smartups" with cable Hewlett Packard part number 5061-2575 equivalent to a custom-smart cable), and you want you get it working with a computer running Linux, Unix, or Windows NT, you are reading the righ

1. First, check to see if apcupsd supports your UPS and operating system (see Supported Operating Systems; UPSes and Cables). 2. Second, plan your con guration type (see Choosing a Con guration Type). If you have just one UPS and one computer, this is easy. If you have more than one machine being served by the same UPS, or more than one UPS supplying power to computers that are on the same local network, you have more choices to make. 3. Third, gure out if you have one of the easy setups. If yo

9. To verify that your UPS is communicating with your computer and will do the right thing when the power goes out, read and follow the instructions in the Testing (see Testing Apcupsd) section. 10. If you run into problems, read the Troubleshooting (see Troubleshooting Your Installation) section of this manual. 11. If you still need help, send a message to the developer's email list apcupsd-users at lists.sourceforge.net describing your problem, what version of apcupsd you are using, what opera

We'll describe the possible values here, because they're a good way to ex- plain your UPS's single most important interface property { the kind of protocol it uses to talk with its computer. apcsmart An APCSmart UPS and its computer also communicate through an RS232C serial connection, but they actually use it as a character channel (2400bps, 8 data bits, 1 stop bit, no parity) and pass commands back and forth in a primitive language (see APC smart protocol) resembling modem-control codes. The d

of the models, particularly USB enabled models, can be run in multiple modes, so they may appear more than once in the table. APC is putting out new models at a furious rate, and so it is very likely that your model is not listed in the table. If it is USB enabled, it will probably work in USB mode. Please note that some of these new models are extremely inexpensive, so they are stripped down versions of more expensive units, and as such they do not o er as many features, so some of the example
