Developing Your First Application

We use the tcps2 example to illustrate how to build an application for UC-7420/7410. The
procedure outlined in the following subsections will show you how to build a TCP Server program
plus serial port communication that runs on the UC-7420/7410.

Testing Environment

The tcps2 example demonstrates a simple application program that delivers transparent,
bi-directional data transmission between UC-7420/7410’s 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-7420/7410 via an RS-232 connection. At the remote site, data can be transferred between
UC-7420/7410’s Ethernet port and PC 2 over an Ethernet connection.
