About this product
The Sunix DPAS04HP0 DevicePort Advanced is a secure, Ethernet-enabled serial device server featuring 4 x powered RS-232 ports with WiFi support, designed for controlled serial over IP deployments where data protection and flexible port expansion are essential.
Overview Summary
Sunix DPAS04HP0 DevicePort Advanced Serial over Ethernet Server
The Sunix DPAS04HP0 DevicePort Advanced provides reliable serial device connectivity over Ethernet with integrated WiFi support. Built on the Sunix DPL2000Q chipset, it supports upstream and downstream daisy chaining for scalable deployments of up to 255 serial ports, making it ideal for industrial, automation, and secure IT environments.
This device features advanced auto-detection and intelligent port mapping to simplify configuration and reduce setup time. Powered via USB, it adds an additional layer of protection against online spy recording. DevicePort Dock Mode further enhances security by restricting Ethernet connectivity directly to a PC rather than a shared router or switch.
Performance tier: Industrial-grade
Uses: Serial device networking, industrial automation, secure data acquisition, legacy equipment integration, controlled RS-232 over IP
Overview
DPAS04HP0 allows users to expand four RS-232 Powered COM 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(RegTM) 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 DPAS04HP0 DevicePort Advanced is engineered for environments requiring secure and scalable serial over Ethernet connectivity. With four powered RS-232 ports and support for Ethernet and WiFi communication, it enables legacy serial devices to be integrated into modern IP networks without compromising security.
Its daisy chain capability allows expansion up to 255 serial ports, supporting complex installations while maintaining centralized management. The Sunix DPL2000Q chipset ensures stable performance at data rates up to 115 Kbps, while advanced ESD and line protection safeguard connected equipment in electrically noisy environments.
Designed with security in mind, the USB-powered architecture helps prevent online spy recording, and DevicePort Dock Mode restricts Ethernet access to a dedicated PC, making it suitable for sensitive applications where controlled access is required.
