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

IMPORTANT: You CANNOT connect a normal serial cable to the Smart-UPS. If you do connect a normal serial cable and terminate both ends, the Smart-UPS will likely shut down or exhibit other strange behaviors.

The cable required for a serial port on a Smart-UPS is also proprietary and has a non-standard pinout. You need a "Smart Signalling" capable serial cable (RS-232). The model number I ordered was 940-1524C and I can confirm it works with the Smart-UPS SC 1500 and 2200. Note that the "15" in that model number is the length of the cable, so any model that varies in those digits will work the same.

If you want to create your own serial cable, you will need a male DB9 connector, and a female DB9 connector. Wire them up with the following pinout:
