1. A system, comprising:

  • a plurality of nodes connected in a peer-to-peer network via a communication interface wherein at least one node of the plurality of nodes comprises;

    a transceiver;

    at least two connectors;

    at least one termination resistance module coupled to the transceiver, the at least one termination resistance module providing termination resistance within the node;

    a first detection circuit coupled to a first connector of the at least two connectors; and

    a second detection circuit coupled to a second connector of the at least two connectors, wherein the first and second detection circuits are configured to detect that the node is coupled to one or more other nodes in the peer-to-peer network, and automatically adjust the termination resistance based on the detecting; and

    a controller coupled to the first detection circuit and the second detection circuit, wherein the controller is coupled to a first ground that is electrically isolated from a second ground coupled to the communication interface.
