The Input/Output (I/O) Receiver module is utilized in all
I/O racks (except for the first I/O rack in a Remote I/O
station) to provide an interface for address, data, and control signals between the Series Six CPU and I/O modules;
it also provides a link in a daisy chain to other I/O racks.
The I/O Receiver module features and benefits are summarized in Table 1.
