Hi men, I found your video very usefull, but I have a question for you, in this case I can see that you use a USB converter and you connect a a pair differencial cable to the instrument tha give you a temperature and the humiduty and the usb you conect to female cable and I supose taht you connect to the microUSB port of your raspberry, so my question is How may I read the modbus registers but I want to use the UART pin and read form the port ttyAMA0?, I hope your answer and excellent tutorial

I did the same but i don't get any ttyUSB :( using a Raspbian Stretch version on a Raspberry pi 2B Any idea why it might not be working?

Fantastic Raspberry Pi Modbus information Will this work on the New Orange Pi-5 SBC to run a PWM servo motor controller? Thank you

Great Video, does the USB port detection works similar as on an Raspberry Pi emulator on PC?

Hi! Thank you for a very instructional video! I looked over your "Finding and Listing Modbus Sensors Over RS-485" but wonder if there is any easier way to list the modbus address without having to use Siemens 1200 PLC I am very new to this type of programming so any simplifications are greatly appreciatedbrbrCheers,

Hi, awesome video by the way, helped us alot, but we are facing a problem with 2 of our sensor when we try to connect our sensors together We connected 10 sensors by series, but 2 of the sensors when connected in series keep giving us invalid response error, check sum error But when we connected it directly to the usb without connecting the sensor in series(individually ), it is able to work We tried to change the wiring, but it keeps ended up getting that same error, so i am hoping that you can give us some thoughts on how we can debug it, or is there any setting that disable the sensor ability to connect in series(?) Hope to get a reply soon

You don't have to save devices lists and compare them, just run dmesg -w|grep tty, and plug your usb-rs485 device in, you will see tty number which system gave to your device

Nice video Can you please tell me the specs for the temperature/humidity sensor that you're using here?

Is it possible to connect multiple devices using only one adapter?!

thks for this video it's exactly what i'm looking forbri'm very new to this field and i have one prject: i have a Camera connected with the RPi and with the help of OCR I extract the text from the picture and I have to transfer know this text throught CAN bus i wanted to use RS485 CAN HAT but I find it as easy using usb to rs485 please can you help me?
