The TTConnect 616 is designed for application development and support of Ethernet in vehicle network architectures. In addition to Ethernet the device provides standard interfaces like CAN, LIN and FlexRay as well as digital and analog I/Os, and can wake up on activity from any of its interfaces. The versatile switch includes 6 x 100BASE-T1 BroadR-Reach® physical layer interfaces that enable 100 Mbit/s full-duplex communication over unshielded twisted single pair (UTSP) cabling in addition to one 100BASE-TX port. TTConnect 616 was specifically developed for vehicles and machines used in rugged operating environments and at extreme operating temperatures. It is protected by a proven, robust and compact housing, designed for the off-highway and agricultural industry.
