An example embodiment of the present invention relates to a method and corresponding apparatus that terminates circuit connectivity in a bus by determining location of an instrument on the bus, and based on coupling a terminating resistance to the instrument. The example embodiment may couple a terminating resistance with the instrument placed at the end of a bus by employing at least one male-to-male connector arranged to establish a connection between the female receptacles of the terminating resistance and the bus. In order to determine a state of termination of circuit connectivity in a bus, an example embodiment of the present invention may connect a transceiver to a terminating resistance and determine a state of termination of circuit connectivity in the bus as a function of sensing receive activity in the transceiver.
