Hello. This is a technical support team of Sollae Systems. First of all, I think you would better check your cct. If you get a evoluation board, It will be easy to find a problem. If not, I recommend you do a simple test of CSE-M53. I think you did already. But you can use a serial port of PC instead of your serial device. The PC has to be connected Though both serial and LAN. Please refer to 15page of manual about how to test. <a href="http://www.sollae.co.kr/documents/manual/csem53en.pdf" target="new"> Manual Download</a> If serial data can'st transmit to TCP or TCP data can'st taransmit to Serial, You need to check your cct. If you can give us your CCT diagram, we can check your problem. And about Q2, "Established" means TCP is connected. So you don'st need to worry about it.(it means it is not a TCP connection problem, it is a serial problem ) If you have any questions, feel free to contact us again. Thank you. > S.Pongsathon wrote: > ------------------------------------ > I bought CSE-M53 only chip (no evolution board).
