WebResistor connection can be verified by disconnecting DeviceNet power and measuring the resistance across the Can_H & Can_L lines (Blue & White Wire). This can be measured with an Ohm meter. The reading should be approximately 60 Ohms. Very Important: The DeviceNet network will not operate correctly without terminating resistors. Web• Termination: A terminating resistor of 120 ohms must be fitted to each physical end of the network. • Biasing: All Measurlogic meters are equipped will “fail-safe” RS-485 transceivers. This make biasing of the bus unnecessary. If devices from other manufacturers are on the bus it is possible that those devices may require biasing.
