## Story

Hi here is to show you how I start with the WIZ750SR-TTL-EVB kit.

### Preparation

Hardware: Connect board as below picture.

Software:

1. download?**[WIZnet S2E Configuration Tool](https://wizwiki.net/wiki/doku.php?id=products:wiz750sr:download:start)**

2. TCP tool and serial terminal. Below I use sscom5.10a.

### TCP client mode

In client mode WIZ750SR will try to connect to server Remote IP/port that you setting in WIZnet S2E Configuration Tool.

Once the server listen the port and WIZ750SR connect successfully it can start send / receive data.

### TCP server mode

In server mode WIZ750SR will open the port and keep listen.

Once the client connect to the port successfully it can start send / receive data.

### TCP mixed mode

In mixed mode WIZ750SR can as client to connect to server and as server listen port wait client to connect.

**But**?they are only one mode at the same time.

### UDP mode

In UDP mode WIZ750SR can act as a server that sends data fast. But as I try the data rate was limited by the baud rate.
