An electromagnetic service communicating device for coupling to a host in at least two distinct orientations as well as a modular system including a host and a functional device. The electromagnetic service communicating device provides electromagnetic service from the host to the functional device. The electromagnetic service communicating device includes a first member having a first interface connectable to the host and that is pivotally connected to a second member having a second interface connectable to the functional device. The hosts can have differently oriented electromagnetic service interfaces.
