Ready to mount in a cabinet or on a project board. Great set of IO options. A real Swiss Army Knife if you need to speak serial to industrial equipment. Review: Feature-loaded with ground isolation, self-powered from USB and a combination of interfaces - Amazing that for this price you get true isolation. i.e. avoids problems with ground loops / ground level shifts between devices. I opened the case and looked at the circuit board, it has a DC-DC isolator for the power as well as the expected isolation barrier for the signals. The board had a very clear cut-out / clearance trench where the isolation is from the USB side over to the serial connector side. (the serial connectors RS-232/RS-485 are not isolated from each other, but that is fine since it is only intended to use one of those at a time. The point is that this is a USB host to serial adaptor, so the USB/PC is isolated.) Besides that, the FTDI USB/serial port chipset is pretty easy to install in Windows (Microsoft recognizes and automatically downloads driver.) So far all 3 interfaces (RS-232, RS-485, TTL, all worked well for me.) I expect to use TTL for devices like Raspberry Pi that doesn't bother with transceivers. ## Features - This is an industrial USB to RS232/485/TTL isolated converter with original FT232RL inside. It features embedded protection circuits such as power isolation ADI magnetical isolation and TVS diode etc. What's more the USB TO RS232/485/TTL comes with an aluminium alloy enclosure make it solid and durable to work. - The USB TO RS232/485/TTL is very easy to use fully automatic transceiving without delay. Due to its fast communication stability reliability and safety it is an ideal choice for industrial control equipments and/or applications with high communication requirement. - Fully automatic transceiver circuit with no delay ensures the USB port communicates with different interfaces fastly and stably without interfering each other - Onboard unibody power supply isolation provides stable isolated voltage needs no extra power supply for the isolated terminal - High quality USB-B and RS232 connectors smoothly plug/pull ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07L2VLY5D | | Best Sellers Rank | #42 in Serial Adapters #4,186 in Computer Cables & Interconnects | | Brand | waveshare | | Color | USB TO RS232/485/TTL | | Compatible Devices | Devices with RS232, RS485, or TTL interfaces | | Connector Type | USB Type B | | Customer Reviews | 4.7 out of 5 stars 291 Reviews | | Finish | Metallic | | Finish Type | Metallic | | Input Voltage | 5 volts | | Item Weight | 50 g | | Manufacturer | Waveshare | | Mfr Part Number | USB TO RS232/485/TTL | | Model Number | USB TO RS232/485/TTL | | Number of Items | 1 | | Number of Ports | 2 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Specific Uses For Product | Serial communication, industrial automation, embedded systems, data acquisition, robotics | | UPC | 778365986580 614961953574 | | Unit Count | 1 Count | ## Product Details - **Brand:** waveshare - **Color:** USB TO RS232/485/TTL - **Compatible Devices:** Devices with RS232, RS485, or TTL interfaces - **Connector Type:** USB Type B - **Specific Uses For Product:** Serial communication, industrial automation, embedded systems, data acquisition, robotics ## Images ![USB to RS232 / RS485 / TTL Industrial Isolated Converter with Original FT232RL Embedded Protection Circuits and Aluminium Alloy Enclosure for Industrial Control Equipments - Image 1](https://m.media-amazon.com/images/I/61gPi2PJddL.jpg) ## Questions & Answers **Q: Do i have to use the 232 port ot does the usb connection map as a com port?** A: You do not have to use the RS232 port, I use one of these to work RS485 over a BacNet MS/TP network to find my devices. The USB does setup as a com port and is powered from the USB port, the device works flawlessly for what I need it for. For the price, it is well worth it as I use many protocols over the RS485 for device discovery. I am currently looking for a WiFi version of this or a type like this, I work building automation and devices like this make my job much easier. **Q: What type is product, echo or non-echo ? the echo is the reflection of transmitting data on the receiving line.** A: Dear cuetomer, it's non-echo, if there is any other question for our products, please feel free to contact us. Thank you. **Q: Does this work with the modbus protocol?** A: Yes, it will work for whatever RS232/RS485/RS422 protocol you decide to use. **Q: Can i convert from rs232 to ttl?** A: Hi, Sorry,it can't convert from rs232 to ttl. It can only support USB TO RS232, USB TO RS485, USB TO TTL (UART), not support RS232 to TTL. And it can't support USB to convert to RS232, RS485 and TTL at the same time. And RS232, RS485 and TTL cannot be converted mutually. It only support USB to RS232, RS485 or TTL. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Absolute must-have at my work *by C***X on July 20, 2026* Quality, industrial part.
