Not sure if any of you are aware, but you can computer control you LDG AT-600 Pro II and LDG AT-1000 Pro II tuners via the meter port on the back.
I have attached the PDF from LDG on how to wire the cable. Google Groups will not let me attach the executable for the program, but if you are interested I can get that to you.
Additionally I have put two links below, one for the FTDI USB cable and one for the S-Video cable you would need to build the cable. I split the S-Video cable in two (only need one end) and then cut the end pin header of the FTDI USB cable. Then you just need the Black (ground), Orange (TXD), and Yellow (RXD) on the FTDI USB Cable if you buy the same one I had.
