...ng for. (A prime example: I think an UPS should shut down the system when the UPS says the battery has gone below a certain level, as determined by periodic battery tests, rather than shutting down after a certain time period on battery.) A few miscellaneous points about the UPS HOWTO: * While RS-232C interfaces are being phased out on servers and desktops, UPS vendors are just wrapping the serial protocol (or contact-closure lines) in a cheap USB-to-serial converter that may or may not show up as such in the OS. So you get the intersection of the flakiness of serial, plus the flakiness of USB....

I think the time for me to get involved in NUT documentation has come again. Late last week I had to buy a UPS under time pressure. The Eaton unit that thus project gifted me with in 2006(?) died during a severe thunderstorm watch, so it was off to MicroCenter to get a replacement pronto. I wound up buying an APC BN700MC. It was what they had in the performance range I needed. The removable

...ram on this little computer device (>100.00) that was "made" for I/O control. It can do all kinds of things pseudo autonomously and feed back the info to the PC. d) X10 have several interfaces for PC's. I like a little one called the "Firecracker" interface. It uses an RS232C line and can control devices by sending radio signals from it to a reciever module that is plugged into a wall socket. It then embeds the cammands you sent it into the electrical circuits in your home. Another module then plugs into the wall somewhere and you plug devices into it. The little wall m...

I recently bought a new UPS, and I''m attempting to use nut to monitor it. Following setup instructions everything seemed to go well until it came to testing the connection, which failed. There is just one serial connector on the computer, so I set it to monitor /dev/ttyS0. Either that is wrong, or communication is failing. I''ve been told to try minicom to monitor it,

...In one of the offices I'm administering there are about 15 UPS marked with the brand "Ippon BackPro". This brand is widely popular in Russian Federation, while by itself is a 'Made in PRC' megatec clone. Depending on the model this UPSes have got either one standard serial RS-232C interface (cheaper models like Ippon BackPro 400 and Ippon BackPro 600/700 that were manufactured back in about year 2005 or earlier) or dual-port control interface: one serial and one USB. Ippon UPSes are by default shipped with Winpower java-based monitoring and controlling solution which is sai...
