Experimental setup. Four nodes were placed on an RS-485 bus with a total cable length L320 m. Board1 and Board4 are at the cable ends, Board2 is at mid-cable, Board3 midway between Board2 and Board4. Board1 communicates with the master controller (PC) through an USB cable. The routing tables specifically set up for the test are attached below each node. The first tag is address@depth, the others are span:dir, while iface is color-coded
