A connector module includes a signal interface, a wireless communication module and a connector housing. The signal interface is configured to exchange signals between a cable and a communication unit when the connector module is connected to the communication unit. The wireless communication module is configured to exchange information in a first mode between the communication unit and a wireless terminal when the connector module is connected to the communication unit, and, when the connector module is disconnected from the communication unit, to exchange information in a second between a memory internal to the connector module and the wireless terminal mode. The connector housing contains the signal interface and the wireless communication module.
