## Overview

The DTECH Industrial Grade RS232 to RS485 Serial Converter is a robust solution for extending RS-232 signals into RS-485 networks. With 600W surge protection and 15KV ESD safeguards, it ensures the safety of your devices. This compact hub supports up to three channels and features automatic baud rate detection, making it ideal for various automation applications.

## Description

Asynchronous Half Duplex Communication    This RS485 to RS232 converter allows to interface your devices using an RS232 communication link to an RS485 link and vice-versa.   A built-in transient voltage suppressor (TVS) enables you to get double 600W lightning surge protection against the lightning strike over RS485 link, and 15KV static protection over RS232 link effectively protect your value devices against high voltage spikes.  Simple Operation   DCPC (Data Collision Protection Control) function can detect the incoming or outgoing data and automatically switch into the send or receive mode, then you don't have to worry about the data collision problems.   It only requires three lines (RX, TX and GND) to get a RS232 to RS485 conversion, making it great for troubleshooting the serial system, fully plug and play.   Standards: EIA RS-232C, RS-485 RS-232 signal: TX, RX, GND (DB9 Female connector) RS-485 signal: D+, D-, GND (Removable 8-pin terminal block with screws, 3 channels RS485 splitter) Speed: Auto tuner baud rate, 300 bps~115200 bps Load Capacity:10 nodes for each channel, max 32 nodes for 3 RS485 channels Max distance: 1.2km Data direction auto-turnaround, no flow control is necessary Protection: 15KV ESD over RS232 link; 600W lightning surge protection over RS485 link Power Consumption 180Ma@9V Power Input:9V ~ 30V DC 300Ma Transmission Media - twisted pair (>=24 AWG ) or shielded cable.   Applications   Computer  Factory industrial automation control system  Micro controller (MCU)  Door safe / Parking system  SCADA (supervisory control and data acquisition)  ...

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great Quality and works great!!
*by W***! on July 21, 2023*

Great quality and works great!!

### ⭐⭐⭐⭐ Es lo compacto del equipo
*by E***S on October 5, 2021*

Lo usé para adaptar las señales rs232 de un analizador de redes eléctricas cck automation

### ⭐⭐⭐⭐⭐ Worked well to extend control system
*by L***S on January 20, 2022*

We needed to extend a commercial lighting control system between modules. They are RS-232 and the distance was too long.This worked well and was straight forward to set up. It is self powered though external power supplies, this way it can just pass data lines. You only need 3 conductors.It was convenient having screw terminals in addition to jacks to make hook up easier.
