Table 134: Assignment of the terminals
Terminal Signal Description
1.0 CAN+ Non-inverted signal of the CAN bus
1.1 CAN+ Non-inverted signal of the CAN bus
1.2 CAN- Inverted signal of the CAN bus
1.3 CAN- Inverted signal of the CAN bus
1.4 Term+ CAN bus termination for CAN+ (for bus termination,
Term+ must be connected with CAN+)
1.5 Term+ CAN bus termination for CAN+ (connecting alterna-
tive for terminal 1.4)
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, terminating resistors must be connected. If TU517 or TU518
is used, the bus terminating resistors can be enabled by connecting the terminals Term+ and
Term- to the data lines CAN+ and CAN- (no external terminating resistors are required, see
figure below).
