Abstract
A system for discovering devices on a common bus without direct communication. Each device on the bus has a unique identification. One of the devices or a computer may be a master or a host. The host may broadcast a request asking every device with an identification value in a particular range to respond. If no device or one device exists on the bus in this particular range, then there is no or one response, respectively. If multiple devices exist within the range, then multiple responses may be received by the host. In a case of multiple responses, the host may re-transmit its request to one or more half ranges. If multiple responses are again received, then the host may again re-transmit its request where the half range or ranges are again split in half. This approach of half-range reduction may be repeated until no more collisions occur.
