USRN540 RS232 to Ethernet RS485 to RJ45 RS422 to TCP IP Converter

I used this for water sensors in an industrial setting. Worked great and was able to set it up in no time.

Cannot communicate with serial ports no matter what settings you use.

Plug-in and start communicating with many serial devices over Ethernet. No software required but Public virtual serial emulation software allows legacy serial application compatibility. One IP and each serial DB9 has a unique port for direct communication. Browser setup has many parameters to support many types of serial devices and IP communication (master or device mode). 2 DC power inputs available.
