WIZ750SR-110 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-110 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-110 is compatible[1] with the WIZnet WIZ110SR S2E module. In addition, WIZ750SR-110 contains an 4-pin GPIO expansion port that can be controlled freely by the user. (analog input or digital in/out)

Also, WIZ750SR-110 is compatible to control command with WIZ107SR(WIZ750SR).

WIZ750SR-110 is the best fit solution to control user's serial device via Ethernet network.

Also compatible with WIZ750SR[2] 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)
