I just purchased a Tripp Lite 850 BC Pro from COSTCO for a very good price. The unit had a RS-232 port, but no cable. The documentation contained no pin-outs, no data about datacom operation, and no software. Therefore, I will have to experiment with the SuSE-provided software in order to get it to work. From previous experience I can say that Tripp Lite answers email (slowly), but provides less than 100% useful answers. Otherwise, the unit itself seems fine. Sorry I can't give bou more info, but this info may give you a clue what you are up against. ... Reed On Sunday 10 February 2002 02:17, you wrote:

Hi all,

I have no experience with UPS, so here my questions are.

1) What kind of software should I use with the UPS? I want the PC to log when a power failure happen, and to turn off when the failure lasts too much. That software must work with serial port, as I do not have USB ports.

2) What is RS-232 connector? Is it common serial port?

3) How much sellers lie? I mean, I have seen some low cost UPS and sometimes they can resist longer than high cost UPS. I know that half load of a low cost one is much less than half load of a high cost one, but I do not find that information very trustful. So, guys and girls, how much does your UPS last?

4) What UPS do you have, and how is your life with it?

Praise
