Just got a remote head to go with my 996XT scanner, well I cant get it to show the display, it lights up, and says, not connected, does the 996xt scanner require a db-9 plug from the rear to the head? if so I did not get one, I got the other cable that goes from the head ,to the front of the scanner and plugs in? if you follow me, will that work? any one have a remote rh-96 head ,there using with the 996xt ,that can maybe shead some light on my problem, any help would be appreciated , god bless, Bill nbohioham@yahoo.com
