It supports up to 32 devices on a multi-drop RS485 network with automatic RX-TX control and a baud rate up to 115.2kbps. Featuring a built-in 600W transient voltage suppressor, it safeguards connected equipment from surges. Compact and bus-powered, it requires no external power or drivers, making it an essential plug-and-play tool for professionals managing complex industrial data communication systems. ## Description When should I use a RS232 to RS485 converter? RS232 to RS485 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). The RS485 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 1 x Terminal Board 1 x User Manual Review: Works PERFECTLY, bus powered, Automatic RS-485 Transmit enable, low latency - I couldn't ask for more, this thing works great! I needed to send some commands to an RS-485 peripheral to provision it, and it worked perfectly. Its totally bus powered (but provides option for external 7-9vdc power on the RS-485 side). The most important thing when using RS-485 half duplex is fast control of the DE (driver enable) line. This thing handles it automatically and perfectly. Able to send RS-485 commands via terminal and when not sending it releases the transmit line quickly to switch back to receive (<1ms). I was originally contemplating putting one of these together out of a RS-485 transceiver IC, and piddling some TTL stuff together to handle the DE line switching, but for this price, I couldn't justify spending the time building it even if the components were free and sitting on the shelf. A good RS232-485 converter is a handy thing to have in your toolbox for debugging if you work with any RS-485 devices, and this one is well built and super easy to use (it even came with a phoenix style screw terminal block, lol) Review: 232 to 485 converter - Easy to use, works great, great value! ## Features - Commercial Grade Bi-Direction RS232 to RS485 Converter used in Industrial Long-haul Communication up to 4000ft (1200 meters) - Mini RS 232 to 485 serial adapter enables the connections of multiple bus nodes and 32 devices can be joined in RS-485 network - Automatic RX - TX Control; RS-232 to RS-485 Converter controls the “Receive” and “Transmit” modes automatically - Up to 115.2kbps baud rate (auto-detect) can be applied to point to point two wire half duplex and point to multi-point two wire half duplex communication - A built-in Transient Voltage Suppressor (TVS) supports 600W anti-surge protection on each line of RS485 link which effectively guard devices from damage ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01CXY9S6M | | Best Sellers Rank | #123 in Serial Adapters | | Brand | DTECH | | Color | Black | | Compatible Devices | RS232 devices | | Connector Type | rs232 to rs485 | | Customer Reviews | 4.5 out of 5 stars 293 Reviews | | Input Voltage | 9 volts | | Item Dimensions | 3.5 x 1.3 x 0.7 inches | | Item Weight | 1.12 ounces | | Item dimensions L x W x H | 3.5 x 1.3 x 0.7 inches | | Manufacturer | Guangzhou DTECH Electronics Technology Co.,Ltd | | Mfr Part Number | DT-9000 | | Model Number | DT-9000 | | Number of Items | 1 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | data communication, CNC, PLC, Desktop computer, Laptop, Raspberry Pi, POS, controller, building automation system, card reader, industrial control unit Modbus Specific Uses For Product data communication, CNC, PLC, Desktop computer, Laptop, Raspberry Pi, POS, controller, building automation system, card reader, industrial control unit Modbus See more | | UPC | 792625939840 600649504664 714131652402 | | Unit Count | 1 Count | | Warranty Description | 365 days after the date of the purchase | | Warranty Type | Limited | ## Product Details - **Color:** Black - **Compatible Devices:** RS232 devices - **Connector Type:** rs232 to rs485 - **Item dimensions L x W x H:** 3.5 x 1.3 x 0.7 inches ## Images ![RS232 to RS485 Adapter - Image 1](https://m.media-amazon.com/images/I/5160fZaKSbL.jpg) ![RS232 to RS485 Adapter - Image 2](https://m.media-amazon.com/images/I/61P738FXieL.jpg) ![RS232 to RS485 Adapter - Image 3](https://m.media-amazon.com/images/I/615IwN2YGlL.jpg) ![RS232 to RS485 Adapter - Image 4](https://m.media-amazon.com/images/I/61wj4fLejQL.jpg) ![RS232 to RS485 Adapter - Image 5](https://m.media-amazon.com/images/I/61q4k+4fW1L.jpg) ## Questions & Answers **Q: Does this device support node addresses on the rs485 network? seems not, so how do i address a particular device?** A: Your RS-485 end device has to handle the addressing. This device simple converts RS-232 to RS-485. Any RS-485 devices hanging on the other end have to have their own addressing scheme via the protocol you're using. **Q: Does it work with modbus ascii rs485 devices?** A: Yes, this RS-232 to RS-485 adapter works for modbus ascii rs485 devices. If there is any usage issue, please feel free to contact us via the order anytime. **Q: Does the baud rate auto-detect work if the RS232 side listens only (no transmission)?** A: Only there is signal transmission between RS232 and RS485, the baud rate will be auto detected. **Q: Does this do 485 to 232?** A: Yes, I used this converter for Modbus communication from rs-485 to rs-232. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works PERFECTLY, bus powered, Automatic RS-485 Transmit enable, low latency *by T***E on December 6, 2019* I couldn't ask for more, this thing works great!
