14.2.3 Activating the bus terminating resistor
The axis bus must be terminated between axis bus low (AL) and axis bus high (AH) at the first and
last physical node each by a resistor (120 Ω).
The 8400 controller is provided with an integrated bus terminating resistor, which can be activated
via the DIP switch labelled with "AB":
