Note 1. Specify full-duplex communications method and turn OFF the Xon/Xoff con-
trol in the following cases:
• If the Host Link Unit is connected to a host computer and no commands will
be sent from the Host Link Unit to the host computer.
• If a PC is connected.
In the above cases, actual communications control is executed in half du-
plex even though the full duplex communications are specified. If the Host
Link Unit is used simultaneously with the CPU’s host interface, full-duplex
communications must be specified to enable normal communications.
2. Only full-duplex communications are possible for RS-422 communications
at communications port 2.
