Most companies are not replacing their serial equipment. They are updating the way they talk to it.
The Digi Connect EZ family of serial device servers connects RS-232, RS-422, and RS-485 equipment to IP networks, enabling remote access, centralised management, and data acquisition from a single cloud or on-premises platform. From a single-port compact unit to a 32-port rackmount system, Connect EZ scales to fit any deployment — and every model includes a 5-year hardware warranty and 1 year of LifeCycle Assurance with 24/7 expert support.

Frequently Asked Questions
Q: What is a serial device server and do I need one?
A: A serial device server (also called a serial-over-IP converter) connects RS-232, RS-422, or RS-485 serial equipment to an Ethernet or IP network. If your site has legacy PLCs, SCADA controllers, meters, or automation equipment with serial ports and you want to access, monitor, or manage them remotely, a serial device server is the simplest solution without replacing existing hardware.
Q: Which Digi Connect EZ models does Solsta supply?
A: Solsta Embedded supplies the full Digi Connect EZ family — Mini, 2, 4, 8, 16, and 32 port models — as well as the Connect EZ TS 4 and 8, which are designed as direct replacements for legacy ConnectPort TS and PortServer TS devices. Contact our team for pricing and availability.
Q: Can I replace a ConnectPort TS or PortServer TS without rewiring my enclosure?
A: Yes. The Digi Connect EZ TS is designed as an efficient transition upgrade for ConnectPort TS and PortServer TS environments. It uses the same mechanical footprint and RJ-45 serial pinout, so no enclosure modifications or wiring changes are required. Configuration takes minutes using Digi Navigator.
Q: How are Digi Connect EZ devices managed remotely?
A: All Connect EZ devices are managed via Digi Remote Manager — a cloud platform that enables remote monitoring, firmware updates, configuration push, and health alerts across single or thousands of devices. For air-gapped or high-security environments, Digi On-Prem Manager provides the same capabilities within your private infrastructure.
Q: What security features are built into Connect EZ serial servers?
A: Connect EZ includes Digi TrustFence, which provides encrypted communications (TLS 1.2+, IPsec, OpenVPN), secure boot, role-based access control, and RADIUS/TACACS+ authentication. All devices run Digi Accelerated Linux for a consistent, hardened OS platform.
