Figure 125. Synchronous/Asynchronous Processor-to-Processor
Communication (Direct Wire to Remote Locations)
Figure 126 illustrates how both channels of a single Z80 SIO are used with
modems that have primary and secondary or reverse channel options.
Alternatively, two modems without these options can be connected to the
Z80 SIO. A correct baud-rate generator (Z80 CTC) must be used for asyn-
chronous modems.
Figure 126. Synchronous/Asynchronous Processor-to-Processor
Figure 127 depicts the Z80 SIO in a data concentrator, a relatively
complex application that uses two Z80 SIOs to perform a variety of func-
tions. The data concentrator can be used to collect data from many termi-
nals over low-speed lines and transmit it over a single high-speed line after
editing and reformatting.
