Developing Your First Application
We use the tcps2 example to illustrate how to build an application. The procedure outlined in the
following subsections will show you how to build a TCP server program with serial port
communication that runs on the UC-7400-LX Plus.
Testing Environment
The tcps2 example demonstrates a simple application program that delivers transparent,
bi-directional data transmission between the UC-7400-LX Plus serial and Ethernet ports. As
illustrated in the following figure, the purpose of this application is to transfer data between PC 1
and the UC-7400-LX Plus through an RS-232 connection. At the remote site, data can be
transferred between the UC-7400-LX Plus’s Ethernet port and PC 2 over an Ethernet connection.
