Hey guys I have been scouring the net for some information about these shitty SMT series UPS getting bricked.
I have two SMT1000 here which i bought and put new batteries in, I also ran the ID18 version 15 "Update", one using the NMS card, then the other one using a serial cable thinking that may work. Stupid mistake.
I now have two bricked controller boards. I have removed one controller from a scrap SMT1500 and this appears to have bought one of the units back to life (although it is reporting that it is an SMT1500). It seems to work fine, and warns if the load gets close to 1000VA. Has anyone tried removing the 93LC66 and replacing it with another new programmed one? I am only guessing that this may be where the corruption is happening? I have contacted schneider, they wont sell me a spare PCB (Even though they have scrap units). I would be keen to get a copy of whatever the firmware is on this chip in an SMT1000, flash it into the 93LC66, solder it onto the pcb, and see if that works. APC should be made responsible for this failure of firmware upgrade. Judging by the tech i had on the phone, they know this is a problem.
Would anyone have a .bin file of that chip out of a 1000VA version unit? I can do some testing and get back.
