A carrier develops latent electrostatic images in corporation with a toner and one particle of the carrier includes a magnetic particle, and a coating layer covering the magnetic particle. When the component has been designed using CAD tools the CAD data file defining external surfaces of the component is used as the basis to create a second CAD data file defining the surfaces of the inspection to conform to the corresponding surfaces of the component. The data bits include output function status bits from the transmitting relay on user selected channels, serialized analog data bits on other user selected channels, and virtual terminal data bits on still other user selected channels.
