CAN termination
A CAN bus should be terminated properly to prevent signal reflections. The CANopen Dynamic Inclinometer has
an internal 120 Ohm termination resistor. By default, this is disabled, but it can be enabled with object 3003
h
.
A separate M12 termination resistor and T-connector are also available as accessories for CANopen devices:
Figure 5 - M12 male 5-pin
termination resistor (BCC09MR)
Figure 6 - M12 female 5-pin
termination resistor (BCC0A08)
Figure 7 - M12 T-connector
male 5-pin (BCC08CA)
The advantage of using a separate termination plug instead of the internal termination resistor is that an external
termination plug is clearly visible. This helps to prevent an inadvertent double termination that could cause the
entire CAN bus to malfunction.
