This device is the equivalent of a remote telemetry unit (RTU), as it supports the DNP3 protocol. There is no Ethernet interface, and must be purchased separately from SEL. Also, the devices does not have a web interface or web admin interface. This device is a plain 'n simple device -- minimalistic.

BTW, this device supports DNP3 and MODBUS.

@infracritical Do you have more info about the telnet server? It should be called SEL-704 or -705.

I don't know about the 704 or 705 models. Are they supposed to be serial->Ethernet converters?

I am sorry @infracritical, I meant SEL-734 and SEL-735. Looking at Schweitzer's website they do not look like Ethernet converters, but rather "Power Quality and Revenue Meters".

I've been able to find some on Shodan, they have a telnet server that should reply to the access command. I haven't tested anything yet, for more information please see this Twitter thread.

Given that many different SEL-* devices might reply to the same command could mean there is something in front of them. How about a combination of these?

  • SEL-2032 Communications Processor
  • SEL-2701 Ethernet Processor Guideform Specification
  • SEL-2890 Ethernet Transceiver
  • SEL-3610 Port Server
  • SEL-5010 Relay Assistant Software

The SEL-2032 datasheet and SEL-2701 flyer have more information about the telnet capabilities of these devices.

@infracritical do you have more information about what these devices on Shodan might be?
