 WIZ752SR-125 Product Overview

WIZ752SR-125 is a compact sized serial to Ethernet module using the W7500 Ethernet MCU (SoC based on ARM Cortex-M0 architecture) with External PHY(IC+). WIZ752SR-125 is a protocol converter that transmits data sent by serial equipment as TCP/IP data and converts the TCP/IP data received through the network back into serial data to the serial equipment. It complies with industrial temperature standard.

WIZ752SR-125 is compatible1) with the WIZnet WIZ125SR S2E module. In addition, WIZ752SR-125 contains a 4-pin GPIO expansion port that can be controlled freely by the user. (analog input or digital in/out)

WIZ752SR-125 is the best fit solution to control user's serial device via Ethernet network.
