GridTrust Interfacing Device Setup

The GridTrust interfacing device communicates with the SEL751 relay and with the server. For a proof-of-concept demo, the interfacing device could be excluded to simplify the setup process.

The interfacing device and native device use the same code under the hood, so the setup process for each is nearly identical.

Devices Utilized

The Device demo is comprised of multiple COTS components:

• • NXP LPCXpresso55S69 (PUF Board)
  • Dell Optiplex 7000
  • SEL-751 Feeder Protection Relay

The interfacing device computer connects to the SEL 751 relay (using a USB -> serial port connection); the SEL-751 uses the telnet protocol.

Setup

The Dell computer communicates with the GridTrust server and interfaces with the SEL 751 relay. The connection between Dell computer and the SEL relay can be either a USB-to-USB connection or a USB-to-RS-232 connection.

Refer to the native device setup for more detail. The software packages and filesystem structure are the same.
