Can’t recommend them enough At this point I’ve purchased probably 2 or 3 dozen UART/TTL USB adapters from other brands/sellers in my lifetime. I used to think “they’re all the same- cheap, but they work” - but I realized over time that eventually ended up in the trash for one of several reasons- voltage not supported, baud rate not supported, or (most common) unexpectedly stopped functioning With most of the other brands, you have to guess what voltage is supported- if you need anything other than 3.3v, it’s a dice roll. Ditto with baud rate. Need to support more than 1Mbps? Very few sellers even know the max rate of the chip, let alone disclose it to buyers The DSD products all have clear and complete documentation so you know exactly what you’re getting- they’ll tell you “this model only supports X and Y voltage”, or “this model has a max of Z baudrate”, so you know which variant to get Most (or all) of the DSD products have isolated circuitry so they don’t fry your USB port (or themselves) when you inevitably connect to the wrong pins You get exactly what the listing says. And they seem to make just about everything. My favorite is the UART TTL adapter that has support via jumpers for 1.8v, 3.3v and 5v and some less common voltages in between I will never buy a no-name brand again- these may use generic chips underneath, but DTD is not a generic brand The prices are very good- maybe a little more than sone competitors- but it’s worth paying a few extra dollars when you know it will do everything you need into the foreseeable future and won’t die either Review: Great for 485 2 wire - This devices works well and is easy to set up. Just be aware you can set it up for 4 wire 422 but not 4 wire 485. ## Features - Industrial-grade :The built-in isolated power supply and ADI signal isolation chip can effectively protect computer damage caused by accidental short circuit, electric shock and other damage. - USB to RS485/RS422:Support RS-422 (RxD+, RxD-, TxD+, TxD-, GND) and RS-485(A+, B-, GND) Interface. - High stability: Built-in original FTDI FT232RL chip,Maximum speed up to 3Mbps - Compatibility: Works with Windows 10, 7(32/64bit) , XP, 2003,Liunx,Mac OS Etc. - Customer Support: DSD TECH provides permanent technical support and 1 year product replacement service for this usb to rs485 rs422 converter. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B083XSG1RG | | Best Sellers Rank | #96 in Serial Adapters | | Brand Name | DSD TECH | | Customer Reviews | 4.6 4.6 out of 5 stars (184) | | Date First Available | January 15, 2020 | | Item Weight | 3.87 ounces | | Item model number | SH-U11F | | Model number | SH-U11F | | Number of Items | 1 | | Product Dimensions | 4.25 x 4.17 x 0.98 inches | ## Product Details - **Compatible Devices:** RS485/RS422 devices, Computers (Windows, Linux, Mac OS) - **Specific Uses For Product:** Industrial Equipment - **Connector Type:** Serial Adapter - **Color:** white - **Item dimensions L x W x H:** 4.25 x 4.17 x 0.98 inches ## Images ![SH-U11F Isolated USB to RS485 RS422 Converter Built-in FTDI chip for Industrial Application - Image 1](https://m.media-amazon.com/images/I/71KrA0uml5L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best company for this sort of gear, by far *by A***R on January 12, 2024* If you need RS232, RS485 and similar - especially if you want long term reliability/stability, protection from over-voltage, and flexibility, DSD Tech is the way to go.
