Avoid any currents on the signal return line caused by sources other
than the signal line. Currents on the signal line and the signal return
line should ideally cancel each other out.
The signal return (ground) lines of the dSPACE boards are connected
to ground of the backplane, which is isolated from car battery
ground.
