I am attempting to get a TrippLite BC PRO 850 interfaced for automatic shutdown (as mentioned in earlier post). Any clues why all the weirdness? - I am running the SuSE-provided software. ps -ef dump: nobody 586 1 0 21:22 ? 00:00:00 /usr/lib/ups/driver/genericups -t 4 /dev/ttyS1 root 593 1 0 21:22 ? 00:00:00 /usr/sbin/upsmon nobody 594 593 0 21:22 ? 00:00:00 /usr/sbin/upsmon - I believe I have the correct RS-232 port, because when the daemon runs, the RTS line swings positive. In other words, something happens. - When I apply plus or minus voltage to the CTD and/or DCD lines in the RS-232 port (pins as documented in generic-ups.txt), nothing happens. The system does not shut down. - There is no doc re pin-out in the TrippLite manual. The following site has some relevant pin-out information: http://www.lugor.org/ups/genpower.txt. But, it disagrees with what I actually measure on the TrippLite. I measure a contact closure between pins 1 and 5 when power fail. But the web site indicates the signal should be on pin 6... - The following diagnostic programs do not provide useful results: alta1:~ # upsc localhost Unable to get variable list - Receive timeout alta1:~ # upsct localhost Unable to connect to localhost - Connection failure: Connection refused - This isn't too useful, either: alta1:~ # upslog localhost - 10 Network UPS Tools upslog 0.45.1 logging status of localhost to - (10s intervals) 20020214 215727 NA NA NA [NA] NA NA 20020214 215749 NA NA NA [NA] NA NA 20020214 215811 NA NA NA [NA] NA NA 20020214 215833 NA NA NA [NA] NA NA 20020214 215855 NA NA NA [NA] NA NA 20020214 215917 NA NA NA [NA] NA NA Looks like I've got problems at both ends. ...
