SUNIX DevicePort is the ideal choice to enable your current Legacy I/O devices networking. DPKM21H00 allows users to expand both RS-232 and printer ports over Ethernet connection, and it works as a PCIe add-on card operation on any windows based tiny desktop, laptop, or All-in-one system. With SUNIX DPL2000Q High-Performance Ethernet-UART/Printer controller and exclusive I/O redirection technology, DevicePort creates physical COM and LPT ports that support real time data communication and Ethernet-COM/LPT port hot-plug capability; user can expand legacy port easily without complex software configuration that improves deployment efficiency to achieve greater reliability in commercial and industrial automation applications.
The Sunix DPKM21H00 DevicePort Dock Mode Ethernet adapter is engineered for professional environments requiring reliable serial and parallel port expansion over network infrastructure. It is ideal for connecting legacy industrial devices to modern systems without direct physical interfaces.
Its DevicePort dock mode restricts Ethernet port connections to a dedicated PC, preventing direct router or switch access for improved control and reduced unauthorized interception risk. The device supports auto detection and port mapping for simplified configuration.
With robust electrical protection including 15KV air discharge and 8KV contact discharge ESD protection, this adapter is designed for stable long term operation in industrial and commercial environments.
