6.4.3 Mixed configurations (point-to-point /multi-point)
This is a combination of the two previous connection methods and, depending on the combination chosen, is
able to exploit the two types of connection to the best advantage and hence significantly reduce the probability
of operation failure. The following is an example of a mixed connection:
In this example, if receiver R1 is blocked (with multi-point connection in line L1) this will not cause a failure in
receiver R2. R1 is not at the end of line L1, and so does not need to be terminated. If receiver R2 is blocked, as
the ‘generator’ of the L2 line all receivers connected to it in cascade (R3 and R4) will not receive commands.
