ABSTRACT:
An arrangement for terminating a tap-off line (40) between a bus line (14) and a bi-directional signal driver (38). The arrangement includes a resistor (42) serially connected in the tap-off line and a controllable switch (44) connected across the resistor. There is also provided means (46, 48) for controlling the switch to bypass the resistor when the bi-directional signal driver transmits signals to the bus.
