Introduction
The Moog Model 920 Ethernet Data Multiplexer (Model 920 EDM) is a compact and rugged Ethernet, EtherCAT,
and CAN Bus multiplexer and fiber optic transmission system designed for Industrial Environments and other
applications requiring the transmission of Ethernet and CAN Bus data over an optical link. The Model 920 has
been optimized for low power operation and delivery of non-switched (real time) Ethernet, EtherCAT, and CAN
Bus in a DIN rail mount box.
This document provides Model 920 EDM users with detailed information relevant to the design, configuration,
installation, and operation of the Model 920 EDM. This manual and the appropriate reference documents should
be reviewed prior to installation or reconfiguration of the multiplexer system.
Section 2.0 provides an overview of the complete Model 920 EDM multiplexer system and the key technologies
employed. Section 5.0 provides an overview of the Model 920 EDM Modbus diagnostics. Section 6.0 provides
useful installation instructions and preliminary test procedures.
Appendices in Section 7.0 include a cross-reference for card configuration drawing and any system specific
information, if provided, such as relevant installation drawings and configuration drawings.
