Still, I can't understand why the serial cable I'm using on 1 APC model works fine but if I use that same cable on another (identical) APC then it shuts down immediately. (I double-checked model name and serial numbers behind the UPS devices)

Oh, same cable from another identical UPS that works. Try resetting that 
UPS; it goes something like this: Unplug, disconnect the batteries, and 
press/hold the buttons to make sure the ups is completely dead. Does 
that help?
