Connecting serial cable to PSU shuts it off, huh?

I recent purchased a used Connext (store brand of APC) 900VA UPS. I installed a new battery in it, and presto, it works quite well. The previous owner did not have the data interface cable that came with it, which is a 9-pin serial cable. The motherboard on the system which this UPS supports does not have a serial port, so I ordered a 9-pin to USB adapter cable from eBay (I hold my nose and shop there occasionally).
Problem: plugging the cable into the UPS shuts it off immediately. Even if the cable is not connected to the computer, just plugging in the 9-pin end to the receptacle in the back of the UPS makes the UPS beep once and shut down immediately. I tried unplugging all devices from the UPS and removing the UPS from wall power. Plugging in the 9-pin cable still causes a beep and disables any power output from the UPS.
What they hey? How do I proceed from here?
As far as I can tell, the UPS perfectly, apart from this data cable problem. The UPS will run and pass diagnostics when I power it on, and it also has carried the computer through power outages without any problems.

I'll see what Connext has online. APC may have the right cable, but it will be for an APC unit. The APC site doesn't even acknowledge Connext, understandably so, because they want APC to have a premium reputation, not associated with an unsupported store brand.

That's a space station.
Oh well, I learned something and only wasted five Bucks on my eBay purchase.
