AH500 Module Manual 11.3.4 Installing the DeviceNet Connector After wiring is over, insert the DeviceNet connector to the interface. Tighten the screws of the two sides of the DeviceNet terminals. Note: The cable should be away from the power wire to decrease the electromagnetic interference. The two ends of the shielded wire should be grounded. The 121 ohm resistor should be connected between the white and blue signal wires. 11.3.5 DeviceNet Bus Transmission Distance and Network Topology Structure DeviceNet bus transmission distance is determined by the DeviceNet bus transmission speed.
See the following table on different transmission speed and the corresponding maximum communication distance. 11-12 Tighten the screw of the communication connector to fix the cable to the holes of the connector with a standard slotted screwdriver.
