i have a Skiwire connector that i have had for a couple of years. I was trying to connect to an older sky commander DSC which i have had for 14 years. Never got it to work. I am getting a replacement sky commander DSC the new version xp4 which comes with a serial cable. Can i use the Skiwire i have to connect to it or do i need something different another cable ? i think i am not the first to do so. I have sky safari pro version 5 on an iPhone?
