G Link Cable

What is G-Link cable? 3

I have a 60-inch LG Plasma, model number 60PY3DR, and for the past year I've been trying hard to record it with the built-in TV guide. This site now, when I try to configure it, asks me to somehow configure my Glink cable. What is Glink Cable and where can I get it? Whereby? I need to register my sws.

Glink cable is a cable that converts recording signals from a TV guided device into a recorder or decoder under infrared control.
