Propeller and WIZnet (W5200)

I am interested in controlling a stepper motor, using some sensors and sending the data to a database online. How does the WIZnet physically connect to the internet?

    For physical connections, WizNet recommends a MagJack. Schematics are openly published on WizNet's site as well as Parallax's WizNet for the QuickStart.

    There's also the W5200 datasheet...

    Is this what you mean by physically connect to the internet?

    I use the WIZ820io module as it is a very small footprint module with the magjack and of course only requires 4 SPI I/O plus reset. I use Telnet which is essentially just a serial network connection as well as FTP and HTTP and connect to it from client computers. If you telnet to port 10001 on pbjtech.net you will presented with a datalogger menu but hitting escape will take you to the Forth "shell" where you can interact with the Prop. For instance, typing ".WIZ" will display the current IP and socket configuration and status. This same system could just as easily drive stepper motors and read sensors and your client could "interact" with this Forth shell serial fashion.

    Hi Mike,

    Before I bought the parts to build the system, I wanted to identify the architecture of the design first. When I say physically, I mean what parallax part is actually making the connection. For example an ethernet or wireless connection. As I was reading through the materials for the propeller and Wiznet I was having difficulty identifying what part would actual make the internet connection.

    From your reply it seems you have answered my question. I missed the recommendation of a MagJack as I was reading through the documentation. I just skimmed through the MagJack documentation quick start guide and understand now I can have use a propeller PAX32A, WIZnet 3200 and MagJack combined to have a system connected to the internet.

    I believe the board layout is a bit more complex. Take Peter's suggestion and pick up a WIZ820io.

    Hi Mike,

    Could you provide an example of a collection of parts that would provide a full solution using the propeller PAX32A, WIZnet 3200 and MagJack?

    Javed, as stated in post 2 Schematics are openly published on WizNet's site as well as Parallax's WizNet for the QuickStart.
