The necessary test programs are part of the Vector Driver Setup Files and located in the folder Common. You can download the Driver Setup File from www.vector.com/driver-setup.
If you use Vector‘s CANcable1, you do not need the 120 Ohm resistors, because they are already included in the cable.
If the loop test works fine, you can see the time, the busload etc. If not, you will get a failed message.
