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).
