Waveshare 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 use it to connect on BACnet MS/TP devices and networks to change settings on job sites and it's very easy to use. Just make sure of your polarity! If reversed, nothing shows up. I use it with YABE, a free software and it's just perfect, I can see all the BACnet points and change everything I need without issues.

Tecnología y calidad en los materiales . Me es muy util

This is my second time purchasing these. They work great for use with all my PV, inverter and battery (ESS) equipment. I’ll need about 16 more units. Waveshare manufactures them right.
