Email From
The SEL-2890 cannot receive email. However, most email servers need a return
address for an undeliverable message. This address will also appear in the “From” field
of an email message. The email server will return an undeliverable message to the
“From” address. Therefore, this address should be to someone who is responsible for
the particular SEL-2890. This setting can contain as many as 79 characters.
Email Subject Line
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.
Serial Protocol Routing Enable
Serial protocol routing is a method to route unsolicited serial messages to different IPs
and associated ports depending on an eight-byte header in the serial message. When
unsolicited serial data are received in the SEL-2890 from an IED, the transceiver
compares the first eight bytes of the message to a settable descriptive header. If they
match, the SEL-2890 will then route the message to the IP address assigned to that
message. As an example, assume the following settings have been assigned:
ROUTE = Y, ROUTE_PORT1 = 8001, ACCEPT1 = N, ROUTE_IP = 192.168.0.11,
and HEADER1 = A5. The SEL-2890 will forward a serial message to IP 192.168.0.11
if the first byte received is A5. The A5 is the ASCII-hexadecimal representation of the
message header. Use “?” as a wild card character in the mask (e.g., A5?0).
Appendix E:
ASCII Reference Table contains an ASCII reference table. The important aspect of
serial protocol routing is the ability to send different messages to different locations but
use the same serial port. The SEL-2890 allows you three different headers for routing
to settable IP addresses. A serial routing example is provided in
Section 4: Detailed
Application Examples .
Routing Port n
Routing port designations are needed in order to initiate a connection between two IP
devices. This port number must match the port number of the Ethernet device that will
be receiving the message from the SEL-2890.
Accept Routing Connection n
Two modes of operation to serial routing are receiving and transmitting. Set
ACCEPT
n = Y to put the transceiver in receiving mode, which allows the SEL-2890 to
receive a serial message routed over the Ethernet. However, setting ACCEPT n = Y will
not allow you to initiate a transmission. The SEL-2890 will only accept and reply when
in this mode. To put the transceiver in the initiate mode, set ACCEPT
n = N.
