Note! For CAN applications, the two ends of the cable will have a termination

resistor connected across the two wires. Without termination resistors,

reflections of fast driver edges can cause multiple data edges that can

cause data corruption. Please refer to Figure 2.4 and Figure 2.5 to add-

ing a termination resistor (120 ohms) on your end device (R271 of RSB-

4210, default is none) to avoid this situation.
