I have just designed and produced a number of products that have been designed to take a plug in ethernet to serial pcb based on the Lantronix Xport. I am having issues with the Xport’s RTS that Lantronix have yet to provide a solution and the issue has become urgent.
My requirements are quite simple.
Receive commands via TCP on Ethernet and convert to asynchronous format using 8 data bits, no parity and 1 stop bit (8N1) @ 2400 baud. RTS & CTS are required.
Send any data on the serial in port to ethernet (again 8N1 2400 baud). There is no control on data flow and any buffer over-run is accepted.
We will have to design our own pcb as the footprint and connections are already laid down with the other pcb’s.
My knowledge of Ethernet TCP-IP is limited to the Xport and comprises simply setting IP address and port.
Can you please advice best chip, recommended circuitry and gui program for setting up.
