Guys,I've got no idea what this connector can do.Can someone tell me what I can do with it?

The Virtual RC bug has bit me.I've been playing with my joystick but wanna use my Tx.I know that a Fly Sky-FSGT3B can be used but need to do something now.I really want to buy it but have to wait till my dad approves it.I can get a USB adapter too....Getting back to the topic,what can this connector be used for?Googling it didn't give any answers......

I was too lazy to take some pics .If this one isn't clear enough,I'll take some pics of my radio.
