Communication Connections

The pinout and cable wiring diagrams in this section show how the ports on the EDS-728/828 connect to other devices:

Pinouts are diagrams that indicate the type of signal passing through each of the port’s pins.

NOTE 1. The pin numbers for male DB9 and DB25 connectors, and hole numbers for female DB9 and DB25 connectors are labeled on the connector. However, the numbers are typically quite small, so you may need to use a magnifying glass to see the numbers clearly.

2.The pin numbers for both 8-pin and 10-pin RJ45 connectors (and ports) are typically not labeled on the connector (or port). Refer to the Pinout diagram below to see how RJ45 pins are numbered.

RS-232 Connection

The EDS-728/828 has one RS-232 (10-pin RJ45) console port, located on the front panel. Use either an RJ45-to-DB9 or RJ45-to-DB25 cable to connect the Moxa EDS-728/828’s console port to your PC’s COM port. You may then use a console terminal program to access the Moxa EDS-728/828’s console configuration utility.

EDS-828, EDS-728/828 specifications

Moxa Technologies is renowned for its advanced networking solutions, and the EDS-728 and EDS-828 series of Ethernet switches exemplify this commitment. Designed specifically for industrial environments, these switches deliver exceptional performance, reliability, and versatility, making them ideal for various applications, including factory automation, traffic management, and public utilities.

One of the standout features of the EDS-728 and EDS-828 switches is their robust design. They operate efficiently across a wide temperature range from -40°C to 75°C, ensuring reliable performance in harsh conditions. This thermal endurance is complemented by a fanless design, which minimizes potential points of failure, making the switches suitable for environments where dust and vibrations are prevalent.

These switches come equipped with Gigabit Ethernet ports, providing high-speed data transmission crucial for demanding network applications. The EDS-728 features 8 ports, while the EDS-828 offers 24 ports, allowing for flexible network expansion according to user needs. Both models support a range of protocols, including IEEE 802.1Q VLAN for traffic segmentation, which enhances network efficiency and security.

In terms of network resilience, the EDS series utilizes redundant power inputs with a wide voltage range (12 to 48V DC) to prevent any downtime. In addition, they support various redundancy protocols like MRP (Media Redundancy Protocol) and RSTP (Rapid Spanning Tree Protocol), ensuring continuous data flow even in the event of a link failure.

Security is also a key consideration in the design of the EDS-728 and EDS-828. They support advanced security features such as IEEE 802.1X port-based authentication and Access Control Lists (ACLs), safeguarding the network against unauthorized access and potential cyber threats.

The user-friendly interface of these switches facilitates easy configuration and monitoring. Moxa’s MXview network management software enhances this usability, allowing users to visualize their network topology in real-time, manage configurations, and troubleshoot potential issues promptly.

Additionally, the EDS series is compliant with various international safety and electromagnetic compatibility (EMC) standards, ensuring they can be deployed globally without concerns regarding compliance.

Overall, Moxa Technologies’ EDS-728 and EDS-828 series of Ethernet switches are engineered to meet the demanding requirements of industrial networking applications. Their fusion of robust design, advanced features, and security capabilities makes them an excellent choice for organizations in need of reliable and efficient networking solutions.
