Hi.

First, refer to below two link. it is wiz108sr user’s manual. and reference schematic.
[wiznet.io/wp-content/uploads … _V141E.pdf](http://www.wiznet.io/wp-content/uploads/wiznethome/S2E%20Module/WIZ107_108SR/Document/WIZ108SR_UM_V141E.pdf)
[wiznet.io/product-item/wiz108sr/](http://www.wiznet.io/product-item/wiz108sr/)

wiz108sr output pin is TxD+, TxD- , RxD+, RxD- ,485direction. It is come out UART signal from mcu(w7100). and it is convert UART to RS485 signal (Tx → TxD+, TxD- , Rx → RxD+, RxD-. RTS → 485direction).

Thank you
