    Console session. Telnet port 1025 is the port used for a Console session. Ports 23 and 1026–65534 are used to Telnet through the SEL-2890 and out of its serial port. This type of Telnet connection is common among software and is supported by SEL software.

  • Page 13: Figure 1.1 Example Ethernet Substation Network

    Figure 1.1 Example Ethernet Substation Network 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.
  • Page 14 ➤ Port: The FTP port in the SEL-2890 is 21. NOTE: The SEL-2890 FTP server does not support the PAS V (passive transfer) command. Use the automatic or binary selection for the type of file transfer. Listed below is the FTP file structure for the transceiver.

    The end of an unsolicited message is determined by the MTDELAY setting. The SEL-2890 will send an email message to the email server. If the email server is unavailable the SEL-2890 will retry at a 1-minute, a 10-minute, and a 30-minute interval.
  • Page 16 Effectively, you can send messages out of a serial port through the SEL-2890 and they can be routed to different destinations depending on the first 8 bytes of the message. As many as three different routing masks are available in the SEL-2890.
  • Page 17 IED will receive the data but may not know which slave it came from. This may be acceptable if the serial data are self-identifying. Collisions will occur if all the slave devices answer at the same time. The SEL-2890 transceiver’s Ethernet processor will make the necessary adjustments and will keep retransmitting until a message is successfully sent.

  • Page 30 Making a point-to-point serial data connection between two serial IEDs across an Ethernet network is commonly referred to as serial tunneling. There are four modes of serial tunneling supported by the SEL-2890: Commanded (Cmd), Telnet, TCP, and BTCP. SEL-2890 Instruction Manual...
  • Page 31 Telnet tunnel with IP address 192.168.0.11 and Telnet port 3001. The receiving device may be a port server set in slave mode, a PC, an SEL-2890, or an SEL-2701. In Telnet tunnel mode, a transceiver will try to establish a Telnet tunnel with another transceiver, port server, PC, or SEL-2701 card.
  • Page 32 DHCP stands for Dynamic Host Configuration Protocol. Setting DHCP to “Yes” will allow a DHCP server to dynamically assign an IP to the SEL-2890. You should set up a unique host name if you use DHCP. This will allow you to refer to the transceiver by name rather than IP.
  • Page 33 IP addresses. For example, connect an SEL-2890 to a relay and set the transceiver host name to bkr865_351. To Telnet to the SEL-351 Relay on breaker 865, just open a Telnet session to bkr865_351 as shown below.
  • Page 34 Email messages commonly include a Subject Line. Enter any message you want in this line and it will be displayed in the subject line when the SEL-2890 sends an email message. The subject line can contain as many as 159 characters.
  • Page 35 Ethernet device. The routing IP address is the destination for the serial data the SEL-2890 received and forwarded when it was identical to the descriptive header. After a successful connection, the message will be sent.

    IED that will be communicating with the SEL-2890. Force RTS Low The SEL-2890 allows you the option of forcing the Request to Send (RTS) flow control line to either high or low when Flow Control is set to None. The default value of N should work for most installations.

  • Page 37: Command Summary

    Ethernet connection for at least five seconds for the default serial configuration to be enabled. Now, enter AT+++ within four seconds. The SEL-2890 should respond with the #> prompt. You are now in a Console session.
  • Page 38 Access levels control whether you can perform different operations within SEL products. For example, at Access Level 1, you can view settings by using the SHO command. You cannot change settings unless you are at Access Level 2. The SEL-2890 contains only Access Levels 1 and 2.
  • Page 39 This is much quicker than scrolling through each setting one at a time. When you connect to the SEL-2890 Console Port over Ethernet, you are not allowed to change some settings. The settings are displayed via the SHOW command but are hidden when you use the SET command.

  • Page 40: Ethernet Network Operation Settings

    Ethernet Network Operation Settings TUNNEL Use the TUNNEL command to request the SEL-2890 to establish a serial tunnel across a network. The Tunnel setting needs to be set to Cmd (Commanded mode) for this command to be accepted. Enter TUN 192.168.0.11:3001 <Enter> to have this SEL-2890 establish a serial tunnel to an SEL-2890, SEL-2701, or other port server with IP set at 192.168.0.11 and Telnet port 3001.

  • Page 48 Assume you have two SEL-2890 Ethernet transceivers, designated as #1 and #2, and an SEL-2701. Refer to Figure 4.5. You can now use the TUNNEL command in SEL-2890 #1 to dynamically establish a serial tunnel to SEL-2890 #2 or to an SEL-2701.

  • Page 49: Figure 4.5 Serial Tunneling Network Connection

    SEL-2890 #1 will now be routed through the SEL-2701 to the Host. The SEL-2890 #2 and the SEL-2701 do not actively search for a connection. They wait for someone or some device to initiate a connection. The SEL-2890 #1 is the device that actively tries to make a connection.
  • Page 50 It does not matter if the remote port server is set to master or slave because the SEL-2890 will toggle back and forth until a connection is made. Once a connection is made, the SEL-2890 will stay in that mode until the connection is terminated.
  • Page 51 The master IED sends out a serial message containing something like “Slave with address 10, send me your data.” The SEL-2890 #1 receives this serial data and broadcasts the message to all Ethernet devices on the local subnet. The SEL-2890 transceivers #2 through #5 receive the Ethernet message and forward the corresponding serial data through their serial ports.

  • Page 63: Appendix B: Firmware Upgrade Instructions

    The SEL-2890 transceiver stores firmware in Flash memory; therefore, changing physical components is not necessary. A firmware loader feature is included in the SEL-2890 transceiver. These instructions give a step-by-step procedure to upgrade the transceiver firmware by downloading a file from a personal computer to the transceiver via the serial port.

  • Page 64: Upgrade Procedure

    (e.g., send text files). Step 1. Connect the personal computer to the SEL-2890 transceiver serial port via the SEL-C663 or SEL-C642 programming cable and remove the Ethernet cable from the transceiver.
