I THINK that the K3 accessory connector is a standard 15-pin high density D-sub female connector. Is this correct? The connector in the photo only has 14 pins. I'm placing an order to Mouser and I want to go ahead and get a couple of male connectors. The HD-15 D-sub male is Mouser part number 156-1815 (plus a 156-2010 hood). Phil - AD5X
