I had some time to play with my 3.3VDC idea and it worked! A simple jumper from the 3.3VDC pin to the USB pin was all it took to get the RB493G to recognize the APC UPS. So, it looks like all our RB493G routers will be getting this modification in order for our APC UPS monitoring script to work.
Do we know if MikroTik will make this mistake again on future boards? Will the RB2100 have a USB port with 5VDC or not?
Best,
Brad
