Wiz550s2e


#1

I want to connect the out/put TX and RX of FT232R to WIZ550S2E module as this module uses +_ RX and TX how can I use just One wire RX and TX , i mean (I just have 3 wire one RX one TX and one Gnd ) not TX+ and TX- or RX+ and RX-

Is it possible to connect TX- and RX- to Ground?

Hi,
As far as I know, WIZ550S2E itself have no TX+/TX- and RX+/RX-.
It just have TXD and RXD for RS232 interface.

Anyway, WIZ550S2E seems to have mistaken WIZ550S2E-485/422 integrated WIZ550S2E with 485/422 interface board.

WIZnet also, provides WIZ550S2E-232 integrated WIZ550S2E with 485/422 interface board.

For more detail, refer to WIZnet’s wiki site.
