Testing Environment

The tcps2 example demonstrates a simple application program that delivers transparent,

bi-directional data transmission between the W311/321/341’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 W311/321/341 through an RS-232 connection. At the remote site, data can be transferred

between the W311/321/341’s Ethernet port and PC 2 over an Ethernet connection.
