Description

The WIZ750SR-100 is a Serial-to-Ethernet Module meticulously designed to ensure compatibility and efficient network integration for serial communication devices. It is based on the W7500 MCU from WIZnet and incorporates an external PHY chip, IP101GRI, for enhanced network communication capabilities. This module is engineered to be software and hardware compatible with the WIZ100SR S2E Module, offering a straightforward upgrade path for users of the older module. Key Features: Microcontroller and Ethernet Interface: At the heart of the WIZ750SR-100 is the W7500 MCU, optimized for TTL level serial communication. The inclusion of the external IP101GRI PHY chip enables 10/100Mbps Ethernet connectivity, ensuring robust and high-speed network connections. Serial Communication: The module supports serial speeds of up to 230kbps and is equipped with a 2mm pitch 1x12 pin-header (2ea), facilitating easy integration into existing designs. It also features 4 configurable user I/O pins for enhanced versatility. Status Indication: Integrated status pins provide real-time feedback on PHY link status and TCP connection status, crucial for monitoring the network connection's health. Serial Signals: For UART communication, the WIZ750SR-100 module supports TXD, RXD, RTS, and CTS signals. An EVB version is available for RS-232C communication, maintaining the same signal compatibility. Configuration and Security: Configuration can be performed via serial AT commands or a dedicated configuration tool, with support for a search password to enhance security. Virtual Serial Port and Protection: The module supports the WIZ VSP (Virtual Serial Port) program, allowing for easy virtualization of the serial port over a network. It also features a built-in 10/100Mbps Ethernet ESD Protection IC and a Supervisor IC to improve the stability of the reset function. Compact Design: Despite its extensive features, the WIZ750SR-100 maintains a compact form factor of 50mm x 30mm x 12mm (Length x Width x
