Overview Summary

Description

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.
