Product Description
The GE D20 EME is an Ethernet Management Expansion module designed for the D20 Remote Terminal Unit (RTU) and Substation Controller platform. It acts as a high-performance communications gateway, allowing the legacy D20 architecture to interface seamlessly with modern wide-area networks (WAN) and local area networks (LAN).
The EME module offloads communication tasks from the main D20 processor, providing dedicated resources for managing IP-based protocols. It is essential for substations transitioning from serial-based communications to Ethernet backbones, enabling advanced features like remote engineering access, secure file transfer, and high-speed data reporting to multiple master stations (SCADA).

Application Areas
- Substation Automation: Modernizing D20 RTUs to communicate with SCADA via DNP3 over IP.
- Grid Modernization: Integrating legacy substation equipment into a centralized utility Ethernet network.
- Remote Maintenance: Providing secure, IP-based “pass-through” access for configuring I/O modules and secondary electronic devices (IEDs).
- Multi-Master Communication: Simultaneously reporting data to different utility control centers over a single physical network link.
Product Specifications
- Weight: 0.48 kg
- Mounting: Plugs directly into the D20 horizontal or vertical chassis
- Power Consumption: Typically 5W (drawn from D20 backplane)
- LED Indicators: Link/Activity, Speed, Module Status, and Internal Fault
- Country of Origin: Canada / USA
Operating Precautions
- IP Configuration: Ensure that the static IP address, subnet mask, and gateway are correctly assigned via the ConfigPro software before connecting to the live network to avoid IP conflicts.
- Cybersecurity: Since the EME opens the RTU to Ethernet networks, ensure that unused services (like Telnet or FTP) are disabled and that firewall rules are implemented at the station level.
- Firmware Compatibility: The D20 EME firmware must be compatible with the version of the main D20 processor (e.g., D20ME or D20EME II) to ensure correct data mapping between the serial and Ethernet domains.
- Backplane Seating: Use the module’s extraction levers to ensure a solid connection with the D20 backplane. A partial connection can lead to “Internal Link Failure” alarms and intermittent data loss.
