Hey everyone, first time poster here. Just trying to get started with this tuning stuff.

I finally got my LC-1 all wired up and installed. But I'm running into some difficulty when trying to program it. I hooked the serial cable to my laptop and tried plugging it into both in IN and OUT lines of the LC-1 but it keep getting a no HW found error message. What am I missing here??? The instructions state to hook the Terminator plug to the serial IN but I have no clue as to what the Terminator Plug is. I only have one serial cable that came with the unit. What else do I need to hook up in order to program and use the sensor? Thankf for any help.
