Overview Summary
Sunix DPAS04H00 4 Port RS-232 Device Server with Ethernet and WiFi
The Sunix DPAS04H00 DevicePort Advanced provides a reliable method of connecting up to four RS-232 serial devices across Ethernet networks while also supporting WiFi connectivity. Built around the Sunix DPL2000Q chipset, it simplifies serial device management through automatic device detection and intelligent COM port mapping, allowing legacy equipment to integrate seamlessly into modern network environments.
The unit supports both upstream and downstream daisy chain operation, allowing expansion to as many as 255 serial ports within a single deployment. USB powered operation removes the need for an external power adapter while DevicePort Dock Mode improves security by limiting Ethernet connections directly to a connected PC rather than allowing direct router or switch connections. Integrated ESD and surge protection helps safeguard connected equipment in demanding industrial environments.
Performance tier: Professional Industrial
Uses: Industrial automation, factory equipment, POS systems, laboratory equipment, PLC communication, serial networking, remote device management, legacy equipment integration.
Overview
DPAS04H00 allows users to expand four RS-232 ports over Ethernet connection, and it works on any windows based desktop, thin client, laptop, All-in-one, and tablet PC computers. With SUNIX DPL2000Q High-Performance Ethernet-UART controller and exclusive I/O Redirection Technology, DevicePort creates physical COM ports that support real time data communication, Smart COM on/off-line deployment, and Ethernet-COM port hot-plug capability; user can expand RS-232 COM port easily without complex software configuration. SUNIX DevicePort(RegTM) improves solution deployment efficiency to achieve greater reliability in commercial and industrial automation applications.
Description
The Sunix DPAS04H00 DevicePort Advanced is designed for organisations that require dependable communication between legacy RS-232 equipment and modern Ethernet infrastructure. It enables four independent serial devices to communicate over standard IP networks while maintaining compatibility with existing serial applications through automatic COM port mapping.
Supporting both wired Ethernet and WiFi connectivity, the device provides flexible deployment options across industrial facilities, commercial installations, laboratories, retail environments, and production lines. Its upstream and downstream daisy chain capability allows installations to expand efficiently without significant infrastructure changes, supporting up to 255 serial ports within a single deployment.
Security is enhanced through DevicePort Dock Mode, which restricts Ethernet communication to a directly connected computer instead of allowing unrestricted network connectivity through routers or switches. USB powered operation simplifies installation while reducing cable clutter and eliminating the need for a dedicated power supply.
The integrated Sunix DPL2000Q chipset delivers reliable communication speeds of up to 115 Kbps. Multiple layers of electrical protection including 15KV ESD protection, IEC1000-4-2 contact discharge protection, and line-to-line surge protection help ensure dependable operation in electrically demanding environments.
