## Overview

The DTech RS232 to RS485 Converter is a robust data adapter designed for seamless communication over long distances, featuring advanced surge protection and user-friendly indicators, making it an essential tool for any professional setup.

## Description

Asynchronous Half Duplex Communication    To have a PC in charge of controlling a given process in long haul data acquisition and control applications, this converter allows to interface your devices using an RS232 communication link to an RS485 link and vice-versa.    Double Protection   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   ADDC (Automatic Data Direction 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.   For RS485 2 wire system, 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.   Up to 32 devices can be connected on one network to communicate over a single pair of wires (plus a ground wire), so multiple RS485 devices could be connected to one PC without repeater.    Specific   RS232 Link - 9 pin female port.  RS485 Link - 9 pin male port, 4 position terminal board.  EIA/TIA RS-232C, RS-485 specification.  Transmission Distance - 4000ft over RS485 link, 50ft over RS232 link.  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)  ...  Package Content   1 x RS-232 to RS-485 Converter  1 x Terminal Board  1 x User Manual

## Features

- 600W double lightning surge protection and 15KV static protection protects your value devices against high voltage spikes created by either by static electricity or by surges in the supply voltage
- TX and RX indicators enables you to easily know the status of sending or receiving data respectively
- The passive bi-directional RS232 to RS485 converter supports reliable signal transmission over long distance: up to 4000ft over RS-485 link at a high speed

## Questions & Answers

**Q: Which rs-232 lines it gets power from.  txd?  cts? rts?  which ones?  my application has only txd, rxd and gnd.  will it work?**
A: Yes, the RS-232 to RS-485 conveter works for txd, rxd and gnd application. If need any usage help, please feel free to contact us directly anytime.

**Q: The device needs power.  does it get it from the rs-485 signal lines, from the rs-232 lines, or where?  if from the rs-232 lines, whiich ones?**
A: The RS 232 to 485 adapter is port-powered, normally external power supply is not required. But if you need additional power supply as your case may be, please check the "VCC" pin on the breakout connector, which will allows you to add a DC 7-9V power supply to it.
