## Overview

The DTECH RS232 to RS485 Converter Adapter is a compact, port-powered device designed for robust industrial and commercial data communication. It supports multi-drop networks connecting up to 32 devices over distances up to 4000ft (1200m) with half-duplex communication at speeds up to 115.2kbps. Featuring automatic RX-TX control and a built-in 600W transient voltage suppressor, it ensures hassle-free installation and reliable protection against power surges, making it an essential tool for long-haul serial data conversion.

## Description

RS-232 to RS-485 converters are mostly used in industrial and commercial environments. The reason is that the RS485 converter can be used for multi-drop networks, meaning that you for example can connect multiple RS485 devices to one computer. Up to 32 devices can be connected in one network to communicate on a single pair of wires (plus a ground wire). This type of communication is called half-duplex communication. Most quality RS485 converters can communicate in this manner of up to 4000 feet (1200 meters). RS232 to RS485 serial converter is also fairly resistant to noise which is one more reason why it is favored in industrial environments. Guard Your Value Equipment A built-in transient voltage suppressor (TVS) supports 600W anti-surge, effectively guard your value devices from the hazards of transient surges, lightning. No Driver Required Auto control data flow direction of I/O circuit feature makes it fully plug-and-play. Port-Power No external power supply required, it is port-powered from RS232 data lines and low consumption electricity. Mini-Size with 2 screws and terminal block Specific Standard: EIA/TIA RS232C / RS485 Baud Rate: 300bps - 115.2kbps Working Mode: 2 wire asynchronous half-duplex Communication Mode: Point to Point, Point to Multipoint Transmission Media: Twisted Pair (Wire diameter >= 0.5mm) or Shielded wire Transmission Distance: RS232 Interface: up to 50ft (15m); RS485 Interface: up to 4000ft (1.2km) Surge Protection: RS485 Interface, Each wire 600W Original Packing Included 1 X DTECH RS232 to RS485 Converter

Review: If you know you need one of these, it's a formidable choice - If you're reading this, it's because you know you need - quite specifically - a physical conversion between a D9 RS232 presentation and a screw-terminal RS485! I assume this must have internally house some active electronics to perform the conversion - I can't see that they've listed what brand chip that is (e.g., whether it's a Texas Instruments or a lesser known brand). Regardless - it works. I would guess their stated up-to 115.2kbps baud rate is the certified maximum of whatever brand chip they're using inside. Comes well-packaged (unless I'm mistaken, it's not an anti-static bag - just plastic), and is a pretty lightweight (but good quality) plastic construction itself. The included instruction manual is pretty thorough (see review photos). It includes diagrams for wiring RS485, which is a helpful (physical) cheat-sheet to keep on your desk. For the price - definitely recommended!
Review: If you are trying to convert between RS-232 and RS 485, this works very well and a simple to use.
