WIZ750SR-100 Product Overview

Supported Languages


WIZ750SR-100 is a compact sized serial to Ethernet module using the W7500 Ethernet MCU (SoC based on ARM Cortex-M0 architecture) with External PHY(IC+). WIZ750SR-100 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.

WIZ750SR-100 is compatible1) with the WIZnet WIZ100SR S2E module. In addition, WIZ750SR-100 contains an 4-pin GPIO expansion port that can be controlled freely by the user. (analog input or digital in/out)

Also, WIZ750SR-100 is compatible to control command with WIZ107SR(WIZ750SR).

WIZ750SR-100 is the best fit solution to control user's serial device via Ethernet network.

Also compatible with WIZ750SR2) is designed to be used. Users can use various kinds of boards if only changing board selection in firmware. (ex WIZ750SR, WIZ750SR-100, WIZ750SR-105, WIZ750SR-110)
