Can't do a data transfer - Version 3 (serial cable)

Last Updated: 08/21/2013
Using a black DB-9 serial cable? 
Check the plug going into the radio - does it have 3 black rings and 4 silver (this is correct)?  

Does it just have two black  and 3 silver rings on cable end? 
If so, needs CT-28A adapter (29 + 28 = 57A).

Version 4 software requires our USB-57A (red in color)//can use our USB-57B (yellow), won't push in as far.
