I successfully used the same cable I already had for connecting my Kodak DC200 Digital Camera to the COMM port of my PC. This cable is under $20 and you can do a search from many online sources at http://www.shopper.com Just use the search words Digital Camera Cable or DC200 or DC300 cable, Olympus makes the same sort of camera I think. One other thing to bear in mind is that if you're using your COMM1 port for a modem and want to use COMM2 for the DA7, make sure it is turned on in the BIOS settings. In my case, I just wanted to quickly upgrade the software, so I unpluged my modem and used COMM1 temporarily. Hope this helps
