You'll need to download the PCIP software from Sunrise and you have to have the cable that goes from the meter to your computer. It's a serial interface.. so make sure your laptop has this port because most newer laptops did away with serial and went to all usb. Once you're all plugged up and have the software, you pretty much change everything in the program and save it to your meter.
