Frequently Asked Question
HIL devices that support the CAN communication protocol are: HIL 404, HIL 602+, and HIL 604.
HIL 602+/604 has two separate CAN controllers, with separate connectors, running on a 100 MHz reference clock. These two controllers (referenced as CAN 1 and CAN 2) can be connected to the CAN network through a standard 9-pin D-sub type male connector with the following pin-out:
The HIL 404 has two separate CAN controllers, routed to one D-SUB connector. To set up hardware for loopback communication, it is necessary to connect CAN 1_L (pin 2) to CAN 2_L (pin 9) and CAN 1_H (pin 7) to CAN 2_H (pin 4) as well. The 120 Ohm resistors are connected between CAN_L and CAN_H pins on both sides.
