Hi Saulius, The spec you sent me is simply a Megatec excerpt: http://www.networkupstools.org/protocols/megatec.html So Socomec is simply a megatec rebranding (selling by simply putting its name on). As per the NUT compatibility list (http://www.networkupstools.org/compat/stable.html), Sicon are supported by the powercom driver. But since it's a megatec unit, you should preferably try the megatec driver Thanks to report back so that we can update the compat. list.
