you're right that the cabling info are unclear and for some even wrong. you'll find attached what you need. FYI, the RJ12 version is pure serial (while it's counterpart is a USB connector). The more recent version, with versatile cabling, use RJ45. Then the cable is either RJ45 -> USB or RJ45 -> DB9. cheers, Arnaud -- Linux / Unix Expert R&D - MGE Office Protection Systems - http://www.mgeops.com Network UPS Tools (NUT) Project Leader - http://www.networkupstools.org/ Debian Developer - http://people.debian.org/~aquette/ Free Software Developer - http://arnaud.quette.free.fr/
