Terminal Signal Description
1.6 Term- CAN bus termination for CAN- (for bus termination,
Term- must be connected with CAN-)
1.7 Term- CAN bus termination for CAN- (connecting alterna-
tive for terminal 1.6)
1.8 CAN-GND Ground potential of the CAN bus
1.9 CAN-GND Ground potential of the CAN bus
At the line ends of a bus segment, termination resistors must be connected. If TU517 or TU518
is used, the bus termination resistors can be enabled by connecting the terminals Term+ and
Term- to the data lines CAN+ and CAN- (no external termination resistors are required, see
illustration below).
