JACE controllers may include one or more special-use ports, for example one or more Echelon (LON) FTT-10 ports. Usage of such a port requires a specific driver. In this example, the Lonworks driver (each LonNetwork) associates with a specific LONn port, which is configured under that network component. For details, see the Lonworks Guide.

Other special-use ports may appear as the evolution of JACE products continue.
