7.7.1 Galvanic Isolation
The CANnector has four interface islands on the D-Sub connectors X1, X2, X3 and X4. Each of the
four islands is galvanically isolated from the other islands. Within an island the interfaces for
CAN-FD, CAN high-speed, digital I/O, and LIN are galvanically connected to one another. The
shielding of the cable and/or the metal collar of a D-Sub connector is directly connected to the
housing.
For connectors X2 and X4 the isolation voltage is 1 kV. For connectors X1 and X3 the isolation
voltage is 4 kV for 1 seconds.
7.7.2 Rescue Kernel
Pin 6 RK Enable of connector X1 is checked when the device is switched on or booted and
identifies whether the system starts up normal or the rescue kernel is activated. If an active user
configuration in the flash storage obstructs external access to the device or if the operating
system is corrupted, the Rescue Kernel can be used to fix this situation.
► To force the device into Rescue Kernel, connect pin 6 and pin 5 of X1.
► Switch on the device.
→ Device checks the input on pin 6 during start-up and starts the Rescue Kernel.
→ LEDs 2-8 are flashing red.
►
Connect IxAdmin via Ethernet (check default IP address on the device label).
►
To repair the device see information in online help IxAdmin.
► Restart the device.
7.7.3 CAN High-Speed/CAN-FD
CAN interfaces 1 to 4 only support physical bus connection as defined in ISO 11898-2. The
differential signal pair (CAN-low and CAN-high) and ground are connected at the CAN connector.
For ISO 11898-2 high-speed CAN and CAN-FD no bus termination resistor is integrated in the
device.
If a bus termination is required:
►
Connect the bus termination to the cable and/or to the connector.
► Use suitable cable assemblies for the CANnector, available from Ixxat.
