ABSTRACT:
A transparent switch is able to emulate the arbitration and addressing steps for devices that are normally connected to a bus-type communications network. The switch is connected to the devices in a star-type arrangement, with each device connected to a separate port. The switch performs the arbitration and addressing communications with a transmitting device, selects the proper port as defined by the addressing communication, arbitrates with the receiving device, and then switches the communications to occur directly from the transmitting device to the receiving device.
