Serial Connectivity Without Limits

A serial device server is a piece of hardware that connects serial devices — like sensors, controllers, meters, or medical equipment — to an IP network. It lets devices that use serial communication (such as RS-232, RS-422, or RS-485) be accessed, monitored, and managed remotely over Ethernet or cellular networks, just like modern networked devices.

In short: A serial device server bridges the gap between legacy serial equipment and today’s networks, without replacing what already works.

With Digi Infrastructure Management solutions like Digi Connect EZ, serial device servers bridge the gap between legacy serial devices and modern networks. They enable secure serial-over-IP communication, centralized management, and remote monitoring — so organizations can modernize infrastructure without replacing equipment that already works.

Serial-over-IP is a technology that allows serial devices — such as those using RS-232, RS-422, or RS-485—to communicate over an IP network by encapsulating serial data into IP packets.

With Digi Infrastructure Management solutions like Digi Connect EZ, serial-over-IP makes it easy to securely connect, monitor, and manage serial devices across Ethernet or cellular networks. This lets organizations extend the life of existing equipment while gaining modern network visibility and remote access—without changing the devices themselves.

Yes—serial is still widely used today, and Digi Infrastructure Management plays a key role in keeping it modern and manageable.

Serial communication continues to power critical systems across industries like healthcare, transportation, manufacturing, retail, and energy. These devices are often built to last for decades, which is why organizations rely on Digi solutions — such as Digi Connect EZ — to securely connect serial devices to today’s IP networks.

With Digi’s serial-over-IP technology and centralized management tools, teams gain remote access, visibility, and control over serial infrastructure — without replacing equipment that already works.

Yes—serial devices can absolutely be managed remotely, and that’s exactly what Digi Infrastructure Management solutions are built for.

With Digi serial-over-IP devices like Digi Connect EZ, serial equipment connects securely to an IP network, allowing teams to monitor devices, troubleshoot issues, and manage configurations from anywhere. Centralized management tools give IT and operations teams visibility and control across sites — without needing to roll a truck or replace existing equipment.

In short: Digi makes it easy to bring legacy serial devices into a modern, remotely managed network — securely and at scale.

Organizations connect via serial because it’s proven, reliable, and still critical to how many real-world systems operate.

Serial connections are widely used in equipment designed for long service lives — such as industrial controllers, medical devices, traffic systems, and retail infrastructure — where stability matters more than constant change. These devices were built to work dependably for years (often decades), and serial remains a simple, resilient way to move data in demanding environments.

With modern solutions from Digi Infrastructure Management, serial connectivity doesn’t mean being stuck in the past. Digi enables serial-over-IP, remote access, and centralized management — so organizations can keep using trusted serial devices while gaining the visibility, security, and flexibility of modern networks.

Serial communication is commonly used by industrial controllers, sensors, meters, traffic systems, medical devices, POS systems, and building automation equipment. Digi Infrastructure Management, through solutions like Digi Connect EZ, helps organizations securely connect and manage these devices across modern IP networks — without replacing equipment designed to last.

Digi Connect EZ supports common serial protocols such as RS-232, RS-422, and RS-485, making it easy to connect a wide range of legacy and industrial devices to Ethernet or cellular networks.

Serial communication is simple by design, but security comes from how it’s managed. Digi Infrastructure Management adds modern protections — such as encryption, authentication, access controls, and network segmentation — so serial devices connected through Digi Connect EZ meet today’s security requirements.

Yes. With Digi Connect EZ, serial data can be securely transmitted over Ethernet or cellular networks, enabling remote access, centralized monitoring, and integration with cloud-based and remote applications.

No. Digi Infrastructure Management is designed to modernize serial infrastructure without rip-and-replace. Digi Connect EZ lets existing serial devices stay in place while gaining remote access, visibility, and centralized management.

By enabling remote monitoring and troubleshooting, Digi Connect EZ allows teams to detect issues faster, resolve problems without site visits, and proactively manage serial devices—reducing downtime and operational risk.

Yes. Serial remains a reliable, widely supported option for new deployments. When paired with Digi Infrastructure Management and Digi Connect EZ, serial connectivity becomes flexible, scalable, and ready for long-term growth.

Digi Infrastructure Management provides secure serial-over-IP connectivity and centralized device management through Digi Connect EZ, giving IT and operations teams visibility and control across multiple locations from a single platform.
