Quick Overview

Two port RS232 level Serial-to-Ethernet module with W7500 and DB9 and RJ45 connectors


Product Description

The WIZ752SR-125 is an embedded module based on WIZnet W7500 & IP101GRI. WIZ752SR-125 is the protocol converter that transmits the data sent by serial equipment as TCP/IP data type, and converts back the TCP/IP data received through the network into serial data to transmit back to the equipment. It supports two serial ports (RS-232C) so that it can communicate with two serial equipments at the same time.

It is pin-compatible with the WIZ125SR but contains in addition 4 GPIO pins which can be configured by the user as analog input or digital in-/output.
