3.Serial to Ethernet

The ‘Serial to Ethernet’ (S2E) Products are the gateway that converts UART (TTL, RS-232 or RS-422/485) protocol into TCP/IP. It enables remote gauging, managing and control of TCP/IP devices through a UART serial interface.

WIZnet S2E module supports a wide range of pin header types and hardware interfaces.

Device Overview:

WIZ750SR is a compact sized serial to Ethernet module using the W7500P Ethernet MCU, SoC based on ARM Cortex-M0 architecture. This module product 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 supports all relevant serial interface systems(TTL / RS-232 / RS-422/485). WIZ750SR is the best fit solution to control user’s serial device via Ethernet network.

Key Features

  • Serial to Ethernet Module based on W7500P MCU
  • 10/100Mbps Ethernet & Up to 230kbps serial speed
  • Pin-header(2×6) type & RJ-45 connector mounted module
  • 4-Pins Configurable User’s I/O
  • Separate Data UART and Debug UART port
  • Configuration is possible via serial AT commands or via Configuration tool
  • Support WIZ VSP (Virtual Serial Port) program
  • Built-in 10/100Mbps Ethernet ESD Protection IC

WIZ750SR also comes with an evaluation kit and that is known as WIZ750SR-TTL-EVB kit. It consists of WIZ750SR-TTL (3.3V TTL ver.), evaluation board, and cables. This product will help the product design process applying WIZ750SR quickly.
