## Overview

The Utek UT-210T is a compact, port-powered RS-232 to TTL interface converter that supports asynchronous full duplex communication at speeds from 300bps to 115.2Kbps. It features a DB9 female RS-232 connector and a TTL DB9 pin connector, operates without external power via an internal charge pump, and fits in tight spaces with its mini 63x33x17mm size. Designed for seamless integration with existing RS-232 software and hardware, it ensures reliable data transmission up to 5 meters in diverse environments (-25°C to 70°C, 5%-95% humidity).

## Description

In order to facilitate data communication between external devices or intelligent instruments equipped with different standard serial interfaces, it is necessary to convert the standard serial interfaces. UT-210T interface converter can convert the RS-232C serial interface data transmission (TXD) and data reception (RXD) signals into TTL/COMS compatible level, and the converted TTL level is 0-3.3V, No external power supply is required. Driven by a unique "RS-232 charge pump", power can be obtained without initializing the RS-232 serial port. It has zero-delay automatic sending and receiving conversion inside, and the unique I/O circuit automatically controls the data flow direction. Without any handshaking signals (such as RTS, DTR, etc.), it ensures that programs written in RS-232 in full-duplex mode can run in TTL mode without modification, ensuring that it is suitable for existing operating software and interface hardware. Converter transmission rate 300-115.2Kbps.
