Hi. CSE-H53N is cannot link two network devices such as a switching hub. It is just a serial to TCP or UDP data converter. That means it cannot process anything sent and received via lower layers than transport layer. Thus, you cannot use network applications including PING tester and web browser to access to the host through CSE-H53N. Please note that the connection between your device and CSE-H53N should be SERIAL instead of NETWORK. Could you try to use a serial application on your Linux machine?
