Chapter 3 Installation SCANport Link Connection Cable Requirements SCANport cables are available in either male–to–male or male–to–female configuration. Cables (C) of up to 10 meters (33 feet) can be connected from the master to the SCANport device. If a Port Expander (B1) is used, subtract the cable length from the master to the Port Expander from the cable length used to connect the device to the expander (B1 + C = maximum of 10 meters).
Chapter 3 Installation Power Supply Connections The enclosed communications module is powered from a separate 24V dc or 115/230V ac power supply (Figure 3.3). With the open-style communications module board mounted in the drive, no separate power supply connections are required. Figure 3.
Chapter Chapter 4 Troubleshooting Chapter Objectives Use this chapter to help troubleshoot your serial communications system using the LED indicators on the front of the device (Figure 4.1). The communications module is a non-serviceable device that should be returned to Allen-Bradley for replacement when a major fault exists that is attributable to the communications module itself. Figure 4.
