This connection is equivalent to circuit diagram 12. A circuit ac-
cording to diagram 13 is not possible with the IBM Asynchronous
Adapter, as the voltage supplied by this adapter’s power source is
not sufficient for the interfaces. Please refer to the section »Techni-
cal Note« earlier on in this chapter.
You can use the Centronics Blocked Duplex protocol only in combi-
nation with above circuit.
