Subminiature Connectors
The GMA 347 connector kit (011-00813-01) includes two Garmin backshell assemblies. Backshell
connectors give the installer the ability to terminate shield grounds at the backshell housing using the
Shield Block ground kit. The term ‘D-Sub’ (D-Subminiature) connectors have a letter "D" physical
shape. D-Sub refers only to the polarized shell that holds the contacts (pins or sockets) in place. Table
3-3 lists Garmin part numbers for the GMA 347 D-Sub Connectors and the Backshell Assembly.
