Re: [SLUG] UPS woes. - SOLVED
Well after hours and hours of non stop research and testing I have found out that my seemingly unidentifiable UPS, which was purchased so cheaply, is still unidentifiable, BUT I have worked out it makes use of the Fenton UPS Protocol, or Megatec/RUPS2 Protocol...or some sort of clone of that Protocol. After playing around with serial line monitors, and terminal programs I discovered that the UPS is using a Megatec/RUPS like protocol, but it doesn't appear to be completely compatible...well not with the version of Megatec Protocol I was using as a reference. The Official Megatec protocol specs can be found at: http://www.exploits.org/nut/library/protocols/megatec.html When I issued commands to the UPS my self by hand using a terminal program I was only able to get 4 of them to work...well only 4 had a visible or audible result.

RE: [SLUG] UPS woes.
Having a look at the case, which is probably not a good indication !!), it looks like an APC UPS, Or maybe even a SOLA BASIC - they both have similar cases on their low-end models, plus there is a lighter area on the front where a brand sticker may have been which looks about the right size for an APC. Of course, knowing DSE, it could be a wun hung low no-name brand from China - pull the cover off and see what it says inside !

yep, a good little buy. I'm not sure why they even bothered with that
Linux software, and of course it's 386 only, sigh. I've 'reversed
engineered' the protocol and have some software that talks to it, but
it's not complete as yet (I of course want it to do everything under
the sun ... ).
(excuse me just copying and pasting bits of the program below)
Basically, to get it going send the following 4 strings
char ups_init1[] = {0x4D,0x0D,0x4D,0x0D};
char ups_init2[] = {0x4D, 0x0D};
char ups_init3[] = {0x49, 0x0D, 0x49, 0x0D, 0x51, 0x31, 0x0D};
char ups_init4[] = {0x46, 0x0D};
that sets it up and puts it in a mode where you can poll it with
char ups_status[] = {0x51, 0x31, 0x0D};
You'll get back something that can be parsed by scanf as
#define SSCANF_STATUS(buf,status) \
sscanf(buf,(%lf %lf %lf %lf %lf %lf %lf %u, \
status-in_volts, status-unknown1, \
status-out_volts, status-load, status-out_frequency, \
status-unknown2, status-temperature, status-flag)
I don't know what unknown1 and unknown2 actually mean, but flag
changes like :
#define FLAG_NORMAL 1000
#define FLAG_POWER_SMOOTH 101000
#define FLAG_POWER_FAIL 10001000
I might make a sourceforge page if a lot of people have bought these
things.
