THE UNILINK HOST ADAPTER
UNILINK HOST ADAPTER 1–8
USER MANUAL
With appropriate host software, an operator can program, monitor, and control
any P/C or other intelligent device on the TIWAY I network from a single
location.
The importance of the UNILINK Host Adapter is that it provides a
communication link between the TIWAY I network and one or more host
computers. Figure 1–7 is a diagram representing the various host computers
that can be connected to a UNILINK Host Adapter, and the typical devices that
can be controlled in a TIWAY I network.
