“I bought two of theses devices as I wanted an RS232 stream between two rooms via my LAN. Until I read through the Wiki document for this device, I missed the requirement to connect my TX ( data stream I wish to SEND ) to the terminal labeled “RX” and similarly my RX to the terminal labeled “TX” . I used the IP addresses ( initially .201 and .202 ) to access the internal web server and tweak the config.”
