Page 9: Overview
The optional adapter CAN-PCIeMini/402-DSUB comes with a DSUB9 connector, selectable on- board CAN termination and an adapter cable. CAN-M.2/402-2-FD is fully backwards compatible with CAN and can also be used in Classical CAN applications. The independent CAN nets are driven by the ISO 16845:2004 certified esdACC (esd Advanced CAN Core) implemented in the Intel FPGA. -

WARNING Hazardous Voltage - Risk of electric shock due to unintentional contact with uninsulated live parts with high voltages inside of the system into which the CAN-M.2/402-2-FD is to be integrated. → Disconnect all hazardous voltages (mains voltage) before opening the system. - Page 16 Close the system's case again. NOTICE Please note that the CAN bus has to be terminated at both ends! esd offers special T- connectors and termination connectors for external termination. Additionally, the CAN_GND signal has to be connected to earth at exactly one point in the CAN network.

Therefore, the practical maximum number of nodes, bus length and stub length are typically much lower. esd has concentrated her recommendations concerning CAN wiring on the specifications of the ISO 11898-2. Thus, this wiring hints forgoes to describe the special features of the derived standards CANopen, ARINC825, DeviceNet and NMEA2000. -

7.2.1 General Rules NOTICE esd grants the EU Conformity of the product, if the CAN wiring is carried out with at least single shielded single twisted pair cables that match the requirements of ISO 11898-2. Single shielded double twisted pair cable wiring as described in chapter 7.3 ensures the EU Conformity as well. -
