Fig. 1: CU2608 8-port Ethernet switch in protection class IP67 The CU2608 Ethernet switch offers eight d-coded M12 Ethernet ports. Switches relay incoming Ethernet frames to the destination ports. In full duplex mode, they prevent collisions. They can be used universally in automation and office networks. It is installed either via two central 4 mm screws or two diagonally arranged 3 mm screws.
2 ports can be used for Jumbo Frames at the same time. Jumbo Frames are not subject to standardization. It is therefore necessary to verify that the frames used by the application are supported by the CU2208. Version: 2.0.0 CU2608...
