APC Smart-UPS
The following information applies to all APC Smart-UPS models. Most of this I personally tested using a Smart-UPS SC 1500 and a Smart-UPS 2200 (both are rack mount units).

Console Cables
To configure a Smart-UPS, you need to connect via console cable. Depending on your model, the unit may have a USB port, serial port, or both.
USB to RJ50 Cable
The Smart-UPS uses a non-standard USB to RJ50 cable, which looks exactly like an RJ45 but has 10 pins instead of 8. You might need to order one directly from APC or find a used one. The model number I ordered was AP9827 940-0127E and I can confirm it works on both Smart-UPS SC 1500 and 2200.
If you happen to have an RJ50 connector and a spare USB cable, you could make your own with the following pinout:
Serial Cable
The cable required for a serial port on a Smart-UPS is also proprietary and has a non-standard pinout. I ordered a "Smart Signalling" cable (RS-232). The model number was 940-1524C.
