Introduction
Applications
interfaces but do have EIA-232 serial ports. Add an SEL-2030 and SEL-2701
to your network design to connect non-SEL serial devices to your Ethernet
network.

Some other gateway strategies use PCs or other office-grade hardware as the
platform for data collection and conversion. The SEL-2030 performs these
functions and offers a solution that is hardened for the substation environment
without the errors and upgrades inherent in general purpose operating
systems.
Networking for SEL Relays With Card Slots
Use the SEL-2701 to provide a direct Ethernet network connection to an
SEL-400 series relay. All SEL-400 series relays have a card slot that will
support an SEL-2701. Add an SEL-2701 to your SEL-400 series relays to gain
the following features:
➤ Use Telnet for engineering connections to the SEL-400 series
relay.
➤ Use FTP to collect event reports, SER reports, and
COMTRADE oscillography directly from the relay.
➤ Use UCA2 master devices to collect data from SEL-400 series
relays.
➤ Use GOOSE to exchange control data between relays and other
UCA2 IEDs.
An SEL-2701 installed in an SEL-400 series relay provides Telnet terminal
session access to all of the commands, diagnostics, and reporting features
available on the relay serial ports. You can connect to the relay from a PC with
an Ethernet network in the substation or from your desk in a central
engineering office.
