The cable that you need originally came with the UPS. GUARANTEED
(unless the UPS was not truly new and sealed, e.g. if it was "open box").

But, that said, APC is absolutely idiotic for not just using standard
USB sockets on their UPS'.

All of the APC UPS' that I have (500VA, 725VA and 1,500VA) can be
programmed not to beep; some of the earlier models with serial port
interfaces cannot be so programmed. I THINK that all models with USB
ports can be programmed.

Many of the low end UPS' with 300-350VA ratings have what I call "toy
batteries" .... 12 volts at THREE amp-hours. Many of these are in a
compartment originally intended for the very standard 12 volt 7AH
batteries, with insert fins molded into the compartment for the smaller
battery. A little bit of work with some plastic cutting tools will
enable you to upgrade those units to the larger 7AH battery (it's pretty
obvious when you can and cannot do this). I've been told, but cannot
verify, that the 350VA units are actually the same as the 500VA units
except for the smaller battery.

I grabbed the APC UPS (ES350U) from the living room and went to hook it
up to my PC to program it - and NOW I remember why I didn't install the
software. For me to connect the UPS to be able to program it , I need to
buy a USB to RJ45 cable for $39. That's why I never did it ! I paid $30
to buy the UPS - I'm not gonna pay $39 to talk to it !

SO, I just came from BestBuy. They have a Cyperpower 550VA UPS on sale
for $35 - with a cable and software. I'll program IT, put it in the
living room and then unplug it a few times to see if it 'remembers' to
not beep. If that works OK, I'll then use the 350VA APC UPS for the PC
and just turn it off when I lose power. If it doesn't work , I'll
disconnect the pseaker in the APC and return the CP UPS to Best Buy.

William - I had looked before at APC for schematics. I'm with you -
disconnect the speaker and put a note on it to remind myself in case I
ever DO want it to beep.

Thanks guys.

Hi!

APC markets some units that can be told not to beep at all. The BR1500LCD
and BR1300LCD models can both have their beepers configured to stay
off. You
can find at least the 1500 model for sale at Best Buy in the US. It is
advertised as a "Back UPS XS" there. Price is around $144.

For your existing UPS units, a little circuit modification might be in
order. I have "muted" various UPS units in times past by opening them up
(unplug the unit, disconnect the batteries FIRST and *be careful* --
these
things contain hazardous parts that may store energy even after the
battery
is disconnected) and removing the offending beeper. This is effective
but it
will invalidate any warranty your UPS is under.
