Digi Connect EZ 4 TS Concept Kit
Click-to-connect serial connectivity — prove it with your own equipment, in your own environment, before you deploy
Digi Connect EZ 4 TS is a modern, secure 4-port serial device server with software-selectable RS-232/422/485 on every port. It modernizes how organizations communicate with existing serial equipment, connecting automation, robotics control, data acquisition, point-of-sale and centralized device-management systems over IP networks. It boots in seconds, configures in minutes and is built to run for years.
Engineered as an efficient transition upgrade for legacy Digi ConnectPort TS and Digi PortServer TS devices, Digi Connect EZ 4 TS preserves the same mechanical footprint, RJ-45 serial pinout and Digi RealPort workflows while delivering the full Digi Connect EZ platform, including Digi TrustFence security, a built-in Python environment and management through Digi Remote Manager or Digi On-Prem Manager.
Why a Concept Kit?
The Digi Connect EZ 4 TS Concept Kit provides everything needed to evaluate the product before making a larger deployment decision. The kit ships in one box with the device, global power supply, Ethernet cable and a complete set of serial adapter cables, so you can prove value on Day 1.
Built-in Security and Flexibility
Digi simplifies key security requirements for critical infrastructure and distributed systems with enhanced access control, management and configuration capabilities. Digi Connect EZ TS supports a wide range of industry-standard and device-specific protocols using serial tunneling, TCP/UDP connections or Digi RealPort COM-port redirection for remote native COM-port access.

Cord Application and Migration Mapping
How the Cords Are Applied
Each Digi Connect EZ 4 TS serial port uses a 10-pin RJ-45 Digi MEI connector. Use the included adapter cable that converts RJ-45 to the connector used by the target device. Selecting the correct cable comes down to three questions:
- Connector type: Determine whether the target device uses a DB-9, DB-25 or RJ-45 console connector.
- Gender: Select a cable with the opposite gender from the device port. A male device port requires a female cable connector and a female device port requires a male cable connector.
- Straight-through or crossover: Use a straight-through cable for modem-style DCE equipment. Use a crossover or null-modem cable for terminal-, PC-, server- and console-style DTE equipment. Confirm the device pinout when uncertain.
