A terminator is required at each end of the bus cable to prevent the signal from bouncing back and forth on the bus cable.
Dual-ring topology is a network redundant topology where nodes are connected using two concentric rings with four branches. Dual-ring topology is ideal for applications with cabling issues or small networks that are not frequently reconfigured.
