EIA-232 Serial to Ethernet Transceiver

SEL-2890 EIA-232 to 10BASE-T Ethernet Transceiver/Modem

Use the SEL-2890 Serial to Ethernet Transceiver to convert serial EIA-232 connections to 10BASE-T Ethernet. The SEL-2890 provides a method to connect your existing EIA-232 serial devices to an Ethernet network. With the SEL-2890, you can now communicate with a host serial device via a Telnet session using an IP address. A web page can be served from the SEL-2890, allowing the host device to be interfaced with a standard browser such as Internet Explorer. For dedicated point-to-point applications, use the serial tunneling feature to create a virtual EIA-232 connection over an Ethernet network. A built-in email client sends unsolicited messages via email to a predetermined address.
