Digi PortServer TS 4 Device Server

The Digi PortServer TS 4 Device Server is a compact, reliable solution that bridges legacy serial devices with modern Ethernet networks. Designed for standard and secure RS-232 connectivity, this 4-port device server makes it effortless to integrate serial equipment—such as barcode scanners, PLCs, POS terminals, sensors, and industrial controllers—into existing application environments and network management systems. With robust security, flexible port configurations, and dependable remote access, PortServer TS 4 helps streamline data capture, device monitoring, and IT-to-operations communication across data centers, manufacturing floors, and enterprise networks.

• Four versatile serial ports for RS-232, RS-422, and RS-485 — configure each port to match your device signaling and distance requirements. The TS 4 supports multiple interface modes, enabling you to connect a wide range of equipment without changing cables or modifying applications. This flexibility is ideal for industrial environments where equipment with different serial standards must coexist on the same network.
• Secure, remote access and management — protect sensitive data and operations with modern security features such as SSH, TLS/SSL, and HTTPS for web-based management. Remote administrators can monitor, configure, and troubleshoot serial devices from anywhere in your network, reducing on-site visits and downtime while maintaining strong authentication and encrypted communication.
• Easy integration with existing applications — PortServer TS 4 is designed to minimize changes to your application layer. It provides reliable serial-to-Ethernet emulation, supports standard TCP/IP networking, and enables seamless redirection of serial data to servers, databases, or cloud-based services. This helps you extend legacy equipment into contemporary IT ecosystems without rewriting software.
• Web-based and CLI management — configure ports, mapping rules, and network settings through an intuitive browser interface or a command-line interface. The management options empower admins to quickly set up port virtualization, static or DHCP IP addresses, and port redirection, while logging and event notifications help you stay informed about device health and activity.
• Reliable performance for mission-critical applications — engineered for consistent, low-latency data transfer between serial devices and Ethernet networks, the TS 4 supports stable operation in dynamic environments. Its durable design and scalable configuration make it a dependable component for IT infrastructure, plant floor networks, and distributed sensing systems where uninterrupted data exchange matters most.

how to install Digi PortServer TS 4 Device Server

• Power the device with the appropriate external power supply and connect the Ethernet port to your network switch or router. Ensure the device is powered on and the link LED indicates a healthy network connection.
• Connect your RS-232/RS-422/RS-485 serial devices to the four serial ports on the TS 4 using the correct cables and terminators as required by your equipment. Verify signal levels and baud rates match the host application expectations.
• Configure network settings using the web-based management interface or the CLI. Assign a static IP or enable DHCP to ensure the PortServer TS 4 is reachable by your application server or network management system.
• Set up port mappings and COM port emulations to route serial data to the target application or server. This includes selecting the appropriate protocol, data rate, parity, and flow control settings for each port.
• Test connectivity by sending sample commands from the host application to connected serial devices and confirming responses. Use the built-in logging and status dashboards to monitor throughput, error rates, and device health.
• Enable security features for remote management, including enabling SSH or HTTPS, configuring user accounts and passwords with appropriate privilege levels, and applying any required ACLs or firewall rules to protect access to the PortServer TS 4.
• Document your configuration and set up a baseline backup of the device's settings so you can restore quickly in case of changes or hardware replacement. Consider enabling SNMP traps or syslog logging to integrate with your existing monitoring platform.
