## Overview

The DTECH RS232 to TTL Converter is a compact and reliable adapter that seamlessly converts RS232 signals to 5V TTL levels. With automatic baud rate detection ranging from 300 bps to 115200 bps, it ensures optimal performance without manual adjustments. Featuring 15KV static protection, this adapter safeguards your devices from voltage spikes, making it an essential tool for data communication.

## Description

Most of the MCUs use (transistor-transistor logic) TTL levels, and our computer serial COM port generally uses RS232 serial logic level, to get the computer to communicate with the MCU, this RS-232 To TTL Converter can help you convert RS232 into 5V TTL and obtain quick and reliable signal conversion. It has a db-9 female connector on the RS232 serial end, and db-9 male connector on the TTL end. A separate terminal block is included. The terminal blocks plugs into the TTL port, providing screw-lug wire terminations for the port. A small-footprint serial RS232 level shifter breakout tool and no software or drives required, it is suitable for most applications e.g. in factories where TTL signals are used in micro-controller and embedded electronic equipment; to connect with device that only communicates using TTL signals, from your source RS232 device; to monitor and control industrial and automotive sensors and devices.  Specific  9 pin D-Sub DB9 female port 3 pin connector - GND, Logic out (TX), Logic In (RX) Suitable for use with most micro-controllers Baud rate: 300bps to 115.2Kbps Full Duplex Support It’s port powered from RS-232 signal, no external power required Automatic send / receive data, without external flow control signals.  Zero delay automatic transmission   What’s Included 1 x Female RS232 DB9 to DB9 Male TTL Converter  1 x Female RS232 to 3 pinTerminal Board (RXD TXD GND) 1 x User Manual Noted: If your host device doesn't feature a native RS232 port, the versatile converter can be coupled with a USB to RS232 serial adapter (ASIN:B00H8HDS2K ).

## Features

- Reliable Signal Conversion: Port-powered RS232 to 5V TTL adapter converts standard full duplex 9 pin RS232 level to a 3.3V TTL (Transistor-Transistor Logic) signal logic level
- Baud rate will be detected and adjusted automatically from 300 bps to 115200 bps baud
- Compact RS 232 TTL serial adapter with 15KV static protection protects your value devices against high voltage spikes created by either by static electricity or by surges in the supply voltage
- Mini size serial level shifter adapter is with unique serial charge pump drive technology, no need 0f external power supply and serial port initialization
- Real 3 wire communication (TXD,RXD,GND) : a DB9 female connector on the RS232 serial end, DB9 male connector on the TTL end and a separate 3 pin terminal block is included
