Original Packing Included. 1 x DTECH USB to RS-422 RS-485 Adapter Cable 4ft,1 x 9 Pin RS232 female to 5 position Terminal Board ,1 x CD software driver Review: Good - Good product Review: Worked well on Linux - I bought this to connect up to my Aurora solar inverter. Having the little module separate was helpful because my inverter had similar, so I wired the two together with a bit of old Cat5e network cable. The serial adapter itself “just worked” on Linux and the third-party utility I downloaded was able to grab the data flawlessly. ## Features - USB to RS485 RS422 converter It easily lets you connect RS485 or RS422 device directly to your Laptop PC computer USB port - Ideal for industrial environment -provides 600w surge protection and 15KV ESD isolated protection on signal pins to protect costly and often sensitive control equipment against electrical damage - With high performance quality processor chip FTDI-chipset FT232 and IO auto conversion circuitry which makes RS 485 to USB convertor one of the most reliable dongle on the market - 4ft USB serial RS485 RS422 adapter cable supports windows 10 8 7, Mac and more, plug-and-play, No power supply needed - There are no IRQ and COM port conflicts, since the port do not require any additional IRQ, DMA, memory as resources on the system; RS485 for Half duplex and RS422 for Full duplex communication ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08CRFKLRG | | Best Sellers Rank | #117,884 in Computers ( See Top 100 in Computers ) #316 in Serial Adapters | | Brand | DTECH | | Color | Silver | | Colour | Silver | | Compatible Devices | Monitor | | Compatible devices | Monitor | | Connector Type | usb | | Connector type | usb | | Current Rating | 1 Amps | | Customer Reviews | 4.2 out of 5 stars 83 Reviews | | Finish | Matte | | Finish type | Matte | | Input Voltage | 12 Volts | | Item Weight | 0.15 Kilograms | | Manufacturer | Guangzhou DTECH Electronics Technology Co.,Ltd | | Mfr Part Number | DTECH-USB-RS485 | | Model Number | DTECH-USB-RS485 | | Number of Items | 1 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | PC | | Specific uses for product | PC | | UPC | 714131652365 | | Unit Count | 1 Count | | Warranty Type | Limited | ## Product Details - **Brand:** DTech - **Colour:** Silver - **Compatible devices:** Monitor - **Connector type:** usb - **Specific uses for product:** PC ## Images ![DTech USB to Serial RS422 RS485 Adapter with FTDI Chip Supports Windows 10 8 7 XP Mac (1.2m) - Image 1](https://m.media-amazon.com/images/I/61YfHt7D4YL.jpg) ![DTech USB to Serial RS422 RS485 Adapter with FTDI Chip Supports Windows 10 8 7 XP Mac (1.2m) - Image 2](https://m.media-amazon.com/images/I/616E9Dx9RcL.jpg) ![DTech USB to Serial RS422 RS485 Adapter with FTDI Chip Supports Windows 10 8 7 XP Mac (1.2m) - Image 3](https://m.media-amazon.com/images/I/61WkhGCJSxL.jpg) ![DTech USB to Serial RS422 RS485 Adapter with FTDI Chip Supports Windows 10 8 7 XP Mac (1.2m) - Image 4](https://m.media-amazon.com/images/I/610uzAZJ-RL.jpg) ![DTech USB to Serial RS422 RS485 Adapter with FTDI Chip Supports Windows 10 8 7 XP Mac (1.2m) - Image 5](https://m.media-amazon.com/images/I/61+5IWYY1uL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good *by Z***Z on 26 May 2026* Good product ### ⭐⭐⭐⭐⭐ Worked well on Linux *by J***Y on 24 April 2025* I bought this to connect up to my Aurora solar inverter.
