Description

The WIZ750SR Serial-to-Ethernet Module is a compact and versatile networking solution designed by WIZnet, featuring the W7500P microcontroller for efficient serial-to-Ethernet conversion. It is fully compatible, both software and hardware-wise, with the WIZ107/108SR S2E Module, ensuring a smooth upgrade path for existing projects or designs. This module stands out for its adaptability, available in three different versions to cater to various application requirements: WIZ750SR-TTL for TTL version, WIZ750SR-RS232 for RS-232 version, and WIZ750SR-RS485 for RS-485/422 version. Key Features: Network and Serial Speed: The module supports 10/100Mbps Ethernet and offers serial communication speeds of up to 230kbps. Connectivity Options: It features a pin-header (2x6) type and an RJ-45 connector mounted on the module, along with 4 pins configurable for user's I/O needs. Status Indicators: Integrated status pins indicate PHY link status and TCP connection status, providing essential feedback for network management. Serial Signals Flexibility: Depending on the version, it supports various serial signals. The RS-232/TTL version includes TXD, RXD, RTS, CTS signals, while the RS-422/485 version offers differential signaling with 485+/RXD+, TXD+, 485-/RXD-, TXD-, and 485_SEL for selecting between RS-422 and RS-485 modes. Extended Functionality: Optional DTR/DSR signals are supported, with the choice to use status pins or DTR/DSR pins selectable based on application requirements. Configuration and Security: The module supports configuration via serial AT commands or a configuration tool, and includes a search password feature for added security. Virtual Serial Port Support: The WIZ VSP (Virtual Serial Port) program is supported, allowing for easy integration into networked communication systems. Protection: Built-in 10/100Mbps Ethernet ESD Protection IC safeguards the module against electrostatic discharges, enhancing its durability. Compact Design: Despite its comprehensive fun
