USR-TCP232-S2 Ethernet to UART Module | Embedded Ethernet Module

USR-TCP232-S2 is a tiny size SMT Ethernet module that can realize data bidirectional transparent transmission between TTL and Ethernet Port. It can also be applied in RS232/ RS485 by a level shift circuit. USR-TCP232-S2 is based on the Cortex-M0 core. It has characteristics of low power, fast speed, and high efficiency.

Features

• Auto-MDI/MDIX, RJ45 port with 10/100Mbps
• Work mode: TCP Server, TCP Client, UDP Client, UDP Server, HTTPd Client
• Serial port baud rate from 600 bps to 460.8 Kbps, Check bit of None, Odd, Even, Mark, and Space
• Self-defined heartbeat package mechanism to ensure the connection is reliable put an end to a dead link
• Self-defined registration package mechanism, check connection status, and use as custom packet header
• Under TCP Server mode, the Client number ranges from 1 to 16; the default number is 4
