I've got a new HKN4255A 17' negative ground control cable. Can it be used with the Syntor X9000 series? The only thing that appears diiferent is a small port that has a removeable rubber plug on the front of the radio connector housing. Anyone know what this cable was designed for?

It's for the securenet loading. You plug your keyloader in there and vola! Secure capable models have it, non's don't.
