Overview Summary

Description

The Sunix DPKS02HP0 is designed for organizations that need dependable connectivity between legacy RS-232 devices and modern Ethernet based systems. It enables serial devices to communicate over an Ethernet connection while maintaining compatibility with existing hardware and software.

Unlike standard serial adapters, the DPKS02HP0 provides +5VDC through pin 9 of each COM port, allowing compatible serial peripherals to receive operating power directly from the interface. This reduces cable clutter and removes the need for separate power adapters for supported devices.

The integrated Dock Mode feature enhances deployment security by restricting Ethernet communication to a directly connected host PC instead of allowing direct attachment to a network switch or router. This design helps reduce exposure during sensitive data communication and supports environments where controlled connectivity is required.

Expansion is straightforward using the upstream and downstream daisy chain capability. Up to four units can be connected together, providing as many as 12 serial ports while maintaining simplified device management through automatic detection and port mapping.

Built with industrial grade protection, the device incorporates high level ESD and surge protection to help safeguard connected equipment in electrically demanding environments such as factories, workshops, retail installations, laboratories, and control systems.
