## Overview

The TCP232-306 is a versatile serial-to-Ethernet converter featuring a powerful 48MHz ARM Cortex-M0 core, supporting RS232, RS485, and RS422 interfaces. It enables seamless Modbus RTU to TCP protocol conversion with low latency and strong scalability. Equipped with a 10/100Mbps Ethernet port and Auto MDI/MDIX, it offers easy network integration. Its built-in watchdog ensures reliable 24/7 operation, while user-friendly web and AT command configuration streamline deployment in industrial automation, smart traffic, and manufacturing environments.

## Description

USR-TCP232-302, USR-TCP232-304 and USR-TCP232-306 are cost-effective serial to Ethernet converter. They adopt Cortex-M0 solution, which has a main frequency up to 48MHz, providing fast transmission speed. Equipped with RS232/RS485/RS422 serial port and 10/100M Ethernet port, those products can connect to variety of serial devices to achieve transparent transmission via simple configuration to save manpower and shorten the development cycle. These products are widely used in smart traffic, unattended Weighing, manufacturing industry etc. USR-TCP232-302, 304 and 306 are identical in software features, they both support transparent data transmission, Modbus gateway, user-defined webpage, heartbeat packet, registration packet, index function etc. In hardware, TCP232-302 is RS232 to Ethernet converter, TCP232-304 is RS485 to Ethernet, TCP232- 306 supports RS485/RS232/RS422, but RS485/RS232/RS422 can’t work at the same time.

## Features

- ARM core, Cortex-M0 solution, equipped with deeply optimized TCP/IP protocol stack. It has low latency and strong scalability, stable and reliable.
- Supports Modbus RTU to Modbus TCP protocol conversion and multi-host polling.
- Supports hardware and software watchdog, automatically restarts when the device goes down.
- 10/100Mbps Ethernet port and support Auto MDI/MDIX
- Easy to config: built-in webpage and AT command to set parameters.
