I don't have a Kameleon, but I do have the codes for it. Go to
[Link: anycities.com] and look under A/V Switch. You'll need JP1 or a modem upgrade. I think OFA made a Video Accessory code (0308) for the Sony switcher codes, so if the Kameleon has the modem thing (really a coil), which I think it does, call their number and see if you can get the VA/0308 code in your Kameleon.
Tell me if this works, and especially if you discover any codes not listed on my website.
