Terminating resistor
A terminating resistor is integrated in the interface option above the ETH1 interface. A switch is used to enable
or disable the terminating resistor for the CAN bus interface. The L1 LED status indicator indicates whether the
terminating resistor is enabled or disabled.
On The terminating resistor is enabled.
Off The terminating resistor is disabled.
3.5.7.3.2 Shielding
For the interfaces on the 10-pin female connector, the interface shield can be put on pin 2 of the female connector.
A functional ground connection, which can also be used for the cable shields, is located on the interface plate of
the system unit.
