I would like to develop an embedded device that has an Ethernet interface connected to a hone or corporate LAN. One potential usage is to bundle several device close together and work as a bunch of "sensors", and pass data to the server at a remote office. For exampe,3 of them can be connected together one by one with almost no distance in between, then connected to LAN ith just one cable.
Traditionally to connect 3 PCs at one location to LAN, we will need a hub, or a switch. However, my devices will work close together, and Ethernet by its definition support Bus Topology, meaning that all devices or hosts on the network use the same shared communication line. So can I physically use one cable to connect 3 devices to LAN directly without a hub? It will look like a stick, one end is connected to a ethernet jack on the wall (to LAN), the other end is split into 3 tails, connecting to each device. Will it work?
