The DeviceNet trunk line requires a terminating resistor with a resistance of 121 ohms, a tolerance of 1 percent, and a power rating of at least 0.25 Watts at each end of the trunk line. This resistor needs to be directly connected across the signal wires, which are usually blue and white in color. This is important to ensure proper operation and communication between the devices connected to the DeviceNet network. By following this requirement, users can ensure that their network functions correctly and without any issues.
