As we can see the devices at field sites have multiple interfaces and use different communication protocols, which makes connectivity complex and challenging for engineers. To enable the serial-to-Ethernet connectivity simple and help industrial applications optimize their operational efficiency and increase productivity, 3onedata offers easy-to-use solutions to make sure all kinds of serial devices can be connected to an Ethernet-based network.




Today we are going to introduce two models of 3onedata serial device servers: NP301, a 1-port RS-232/485/422 serial device server, and NP302T, a 2-port RS-232 or RS-485/422 serial device server. Featured compact design, rich functions and industrial-approved quality, these two devices can meet your most on-site applications’ requirements. With low-power design and a MTBF exceeding 175,000 hours, they enable your serial-to-Ethernet solutions reliable and cost-effective.
