Termination

DeviceNet uses the CAN bus with terminating resistors at each end of the bus. The
value of the terminating resistor should be 120 ohm. This should be connected
between CAN_H and CAN_L on the bus. Midpoint is connected to 0V for the internal
CAN bus (0V_CAN_ext for the external CAN bus) via a 47nF capacitor.
Terminating resistors are included in the W8 . They can be connected/disconnected
2
by the switches, SW1 and SW2. Both the external CAN bus and the internal CAN
bus have terminating resistors mounted.
Note! When external termination of the buses are used, the termination switches
shall be set in OFF position (disabled).
