This is a bit of a long shot but I have an old Anzen IPT I-1100 UPS and with a pair of new batteries it runs fine, the problem is I'd like to find out the details of the DB9 comm port. Originally it came with it's own serial cable however I haven't managed to track that down yet and I'm pretty sure the wiring is non-standard. I''ve googled extensively, apparently Opti-UPS made almost exact copies of the IPT devices and I've tried creating a serial cable based on the Opti-UPS specs but with little success.
I'm just wondering if there is anyone else out there that used an Anzen IPT UPS and maybe has some technical docs available. They use to be located here but this site is no longer live. Any other suggestions on where else I could post would be welcome.
