HTTP Server

The SEL-2890 provides an easy to use HTTP interface to SEL relays and SEL

communications processors. The three HTTP options are Custom, SEL, User, and Off.

When issuing settings to the transceiver, select one of these four options.

NOTE: A Telnet session has higher priority than the HTTP

interface. The following message will be sent to the web

browser if it is connected when a Telnet session is active:

“Unable to access device due to Telnet session from

IP: xxx.xxx.xxx.xxx.”
