Communications Connections Example
You can connect the serial port to a computer serial port for local
communications or to a modem for remote communications. Other
devices useful for automated communications include the SEL-2020 or
SEL-2030 Communications Processors.
You can use a variety of terminal emulation programs on your personal
computer to communicate with the SEL-351P. Figure 5 presents some
example SEL-351P communications connections (see Table 1 and
contact SEL for more information).
