Modern organizations often need to connect legacy serial equipment to today’s IP-based networks without replacing valuable devices or completely redesigning existing infrastructure. The EZ04-TS00-GLB provides a practical solution for this challenge by combining four flexible serial ports with Gigabit Ethernet connectivity and centralized management capabilities.
The Digi Connect EZ 4 TS, model EZ04-TS00-GLB, is a four-port serial device server designed to connect RS-232, RS-422, and RS-485 equipment to Ethernet networks. Its software-selectable serial interfaces provide flexibility for organizations managing different types of serial equipment across enterprise, manufacturing, automation, retail, energy, and other connected environments.
What Is the EZ04-TS00-GLB?
The EZ04-TS00-GLB is part of the Digi Connect EZ TS family of serial device servers. It provides four RJ45-10 serial ports that can be configured through software for RS-232 DTE, RS-422, or RS-485 operation.
Instead of requiring separate hardware for different serial standards, the EZ04-TS00-GLB allows organizations to configure its ports according to their application requirements. This makes the device particularly useful when an installation includes different generations or types of serial equipment.
The device also provides 10/100/1000 Ethernet connectivity, allowing connected serial equipment to communicate over modern IP networks.
Key Features of EZ04-TS00-GLB
The EZ04-TS00-GLB combines flexible connectivity with management and security capabilities designed for modern network environments.
Four Software-Selectable Serial Ports
The device includes four RJ45-10 serial ports supporting:
- RS-232 DTE
- RS-422
- RS-485
- Software-selectable serial modes
- Multiple RS-232 flow-control options
- Software termination for RS-422 and RS-485
This flexibility makes the EZ04-TS00-GLB suitable for applications where different serial communication standards need to coexist within the same network infrastructure.
Gigabit Ethernet Connectivity
The EZ04-TS00-GLB features 10/100/1000 Ethernet connectivity. Connecting serial equipment to Ethernet allows organizations to integrate traditional serial devices into contemporary IP networking environments without necessarily replacing the underlying equipment.
Remote and Local Management
A major advantage of the Connect EZ TS platform is its management flexibility. Organizations can use Digi Remote Manager for cloud-based management or Digi On-Prem Manager for local management.
This provides administrators with options for monitoring, configuring, and managing connected devices according to their network architecture and operational requirements.
Multiple Administration and Troubleshooting Tools
The platform supports web-based management through HTTP/HTTPS as well as CLI access through Telnet and SSH. Digi also lists tools and capabilities including Digi Navigator, SCP, FTP, protocol analysis with PCAP for Wireshark, syslog, SMTP, NTP/SNTP, ping, traceroute, and iPerf.
These capabilities can help IT and network teams troubleshoot connectivity issues and maintain visibility into distributed serial infrastructure.
Security and Enterprise Connectivity
Legacy serial devices were often designed before today’s network security requirements became standard. Connecting those devices to an IP network therefore requires careful consideration of authentication, encryption, and access management.
The Digi Connect EZ TS platform supports enterprise-oriented security and authentication technologies, including TLS, FIPS, RADIUS, TACACS+, and LDAP capabilities. Digi’s 2026 announcement also highlights VPN and centralized management capabilities as part of the platform’s approach to modernizing serial connectivity.
For organizations upgrading older serial deployments, these capabilities can provide a more manageable path toward integrating legacy equipment into contemporary network environments.

Applications for the EZ04-TS00-GLB
The EZ04-TS00-GLB can be useful in environments where serial equipment must be integrated with Ethernet-based infrastructure.
Industrial and Manufacturing Environments
Manufacturing environments can contain equipment that relies on established serial communication interfaces. A serial device server can provide an Ethernet-based connection while allowing existing equipment to remain in operation.
Automation Systems
Automation equipment frequently uses serial communication for controllers, instruments, and other devices. The software-selectable RS-232/RS-422/RS-485 interfaces of the EZ04-TS00-GLB provide flexibility for different communication requirements.
Retail and Point-of-Sale Systems
Retail environments may include legacy POS equipment, kiosks, printers, scanners, and other serial-connected devices. Connecting these devices through an Ethernet-based serial server can simplify centralized network management.
Energy and Infrastructure
Distributed infrastructure often includes equipment that communicates through serial protocols. Ethernet connectivity and remote management can make it easier for technical teams to monitor and administer these deployments.
Enterprise Legacy Equipment
Organizations do not always need to replace functioning legacy equipment simply because their network architecture has evolved. The EZ04-TS00-GLB provides a bridge between serial equipment and modern Ethernet infrastructure.
Digi specifically identifies industrial automation, robotics, retail POS, kiosks, and embedded systems among the types of environments where serial connectivity remains important.
Why Choose a Serial Device Server Instead of Replacing Legacy Equipment?
Replacing legacy equipment can involve significant costs, downtime, compatibility challenges, and retraining. In some cases, existing equipment may still perform its required function reliably.
A serial device server provides an alternative approach: retain compatible equipment while modernizing how it connects to the network.
The EZ04-TS00-GLB is designed around this modernization concept. Digi describes the Connect EZ TS family as providing a transition path for existing ConnectPort TS and PortServer TS deployments while addressing modern IT and operational technology requirements.
Designed for Long-Term Deployment
Long-term infrastructure investments require more than basic connectivity. Organizations also need dependable management, security, support, and lifecycle considerations.
The EZ04-TS00-GLB includes a 5-year warranty for the base Connect EZ TS device. Digi also offers LifeCycle Assurance options that can extend support, while its management ecosystem provides both cloud and on-premises management choices.
These characteristics make the EZ04-TS00-GLB a strong option for organizations looking to modernize serial connectivity while maintaining a manageable infrastructure strategy.
EZ04-TS00-GLB vs. Traditional Serial Connectivity
Traditional serial connections generally require equipment to remain physically close to the host system or rely on dedicated serial infrastructure. An Ethernet-based serial device server changes this architecture by allowing serial devices to communicate across an IP network.
The result can be greater flexibility in equipment placement, centralized administration, and easier integration with existing network infrastructure.
For organizations with multiple serial devices, using a four-port solution such as the EZ04-TS00-GLB can also consolidate connectivity into a single managed platform.
Global Connectivity and Power Support
The GLB configuration is associated with global power-cord support. Digi’s certification documentation identifies EZ04-TS00-GLB as the Connect EZ 4 TS configuration with a global power cord.
This makes the configuration particularly relevant for organizations deploying equipment across different geographic markets where appropriate power accessories and regional requirements need to be considered.
Conclusion
The EZ04-TS00-GLB is more than a simple serial-to-Ethernet adapter. As a Digi Connect EZ 4 TS serial device server, it provides four software-selectable RS-232, RS-422, and RS-485 ports, Gigabit Ethernet connectivity, centralized management options, and enterprise-oriented security capabilities.
For organizations operating legacy serial equipment, the EZ04-TS00-GLB offers a practical way to connect existing devices to modern IP infrastructure without immediately undertaking a complete equipment replacement.
Its combination of flexible serial connectivity, network management, security features, and long-term support makes the EZ04-TS00-GLB a compelling option for businesses seeking reliable serial-to-network connectivity.
