You can simply connect a RS-232 serial port via ethernet cable using 9-pin DIN to RJ-45 connector adaptors at both ends. No need to convert the serial data stream into TCP/IP over ethernet. Data centers use that for serial connections to stuff like Cisco routers and other terminal applications all the time. However, if the device is truly RS-232 rather than 422/423, it's nominally out of spec past 50 meters and possibly won't go past 9600 baud. Regards. -- -Chuck
