"WebA split bus termination, consisting of two identical resistors (60 Ohm) and one capacitor (typically 4.7 nF), acts like a low-pass filter; high-frequency signals are shunted to ground without affecting the d.c. voltage relationships. Measurements have shown that this can improve noise immunity and reduce emissions. " - Can bus short to ground
