Product Features
Product Overview
The Digi Edgeport Serial Hub (EP-USB-8-D25) is a professional-grade serial connectivity solution designed to expand legacy serial port access through modern USB interfaces. This rack-mountable hub delivers eight external serial ports, enabling IT administrators and industrial system integrators to connect multiple serial devices to Linux or PC hosts without requiring internal expansion cards.
Built for reliability in data center, industrial control, and enterprise environments, the Edgeport hub maintains stable serial communication for devices such as terminals, modems, printers, and specialized equipment. The USB Type A host interface ensures broad compatibility with standard USB ports found on servers, workstations, and industrial computers.
Relevant factors for this section include Host Interface, Platform Supported, Number of Serial Ports (External). When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Technical Overview
The Edgeport Serial Hub implements a transparent serial-over-USB architecture that presents each connected serial device as a standard COM port to the host operating system. This approach eliminates driver conflicts and provides consistent serial port enumeration across reboots and device reconnections.
The hub supports full RS-232 signaling including RTS/CTS hardware flow control, ensuring reliable data transfer for both simple and complex serial protocols. Each of the eight ports operates independently with dedicated buffering to prevent data loss during high-throughput scenarios.

FAQ
What operating systems does the Digi Edgeport Serial Hub support?
The Edgeport Serial Hub supports Linux and PC (Windows) operating systems. Digi provides stable drivers and configuration utilities for both platforms, ensuring reliable serial port enumeration and management. The hub appears as standard COM ports to the host system, maintaining compatibility with existing serial applications and utilities.
How many serial devices can I connect to this hub?
The EP-USB-8-D25 provides eight external serial ports, allowing connection of up to eight separate serial devices simultaneously. Each port operates independently with dedicated buffering, preventing data collisions between connected devices. The hub consolidates multiple serial connections through a single USB host interface.
Is this serial hub rack-mountable?
Yes, the Edgeport Serial Hub features a rack-mountable form factor designed for installation in standard 19-inch server racks or industrial control cabinets. This design conserves workspace and organizes serial connectivity in data center, server room, and industrial control environments where equipment consolidation is essential.
What type of USB connection does this hub require?
The Edgeport Serial Hub connects to host systems via a USB Type A interface. The included 1-meter A to B USB cable provides the connection between the hub and the host computer or server. This standard USB interface ensures compatibility with most modern computing equipment without requiring specialized host adapters.
What serial connectors does this hub use?
The EP-USB-8-D25 utilizes D25 connectors (DB-25) for all eight serial ports. These robust connectors provide reliable connections for serial devices and support full RS-232 signaling including hardware flow control lines. The D25 interface is common in industrial and legacy computing equipment requiring serial connectivity.
Can I use this hub for out-of-band server management?
Yes, the Edgeport Serial Hub is commonly deployed for out-of-band management of servers, network switches, and other infrastructure equipment. By connecting to serial console ports, the hub provides access when network-based management is unavailable, during system boot, or for troubleshooting. The eight-port configuration allows management of multiple devices from a single location.
