USB to RS485 Converter Industrial Adapter Original FT232RL and SP485EEN Fast Communication Embedded Protection Circuits Resettable Fuse ESD Protection

I bought this to connect my PowMr all in one solar inverter to Solar Assistant on an Orange Pi. I was using the USB port on my inverter but it suddenly stopped working one day. At first I thought maybe my USB cable was bad so I tried a couple others but no luck. The price is very reasonable and not much more than a USB cable.Very easy to hook up. My inverter uses an Ethernet port for RS485 - I just cut the end off of an old Ethernet cable and hooked up 2 wires to the Waveshare and plugged everything in. Build quality appears to be good.It's been working fine for about a month now.

I paired this WaveShare RS-485/FT232RL USB interface converter with a thermister temperature collection module to monitor my beer fermentation process. The converter installed easily on my Windows XP SP3 Intel Pentium 4 HT laptop. Many thanks to FTDI for not deprecating Win XP from their driver set!The status LEDs were great confirmation that my software was communicating with the temperature board, or at least trying to during initial development. Once my code was completed, the WaveShare converter demonstrated good stability in 24/7 use during the last two weeks of my fermentation (the brew was started before the software was complete).Unfortunately, I still have not found a way to reset the WaveShare converter via software to automatically recover from my MSExcel 2010 VBA induced ModBus conflicts, especially during software development. Only a manual power cycle by unplugging/replugging in the WaveShare converter would work. This seems to be a Win XP limitation, not the WaveShare converter.I was nervous about trying to integrate these components on such an old laptop, but it all worked as desired. I hope this system description is helpful to lend confidence to others who are interested in a similar experiment.

Works fine. Easy to setup and provided with screw driver and USB extennsion in case is needed

Worked perfectly as a modbus RS485 transceiver. I really like the terminal block for wiring. Works as is with Windows - no driver needed. I only wish it were optó-isolated but at least it’s well rated for voltage isolation. Tested up to 38kbaud with my VFD and worked perfectly. Great product!

Used to troubleshoot and test Modbus packages. This worked great!

Worked well.

The media could not be loaded. Perfect, not too expensive and the extra usb extension is really nice to come with the adapter. The rx & tx lights are useful to see. Simple to install the wires. I tinned the wires just for fun.

Detected as a FT232R FTDI USB Serial Device by my computer I'm using to control my pool. Works perfectly out of the box and isn't interfering with polling or anything. Love that they included a screwdriver and extension USB cable as well in case it's needed. Everything you need in one box!
