One Transmitter, One ReceiverThe simplest network is one transmitter and one receiver (Figure 6). In this example, a termination resistor is shown at the transmitter end of the cable. Although unnecessary here, it is probably a good habit to design-in both termination resistors. This allows the transmitter to be moved to locations other than the far end, and permits additional transmitters to be added to the network if that becomes necessary.
Shouldn't there be ~120 Ohm terminating resistors at either end of the bus?
