hy vfd rs 485 gmoccapy
![:) :)](/media/kunena/emoticons/smile.png)
Update: When I use command ls /dev/tty*, I see my adapter, if I disconnect it, it disappears. If I connect + and - other way on adapter, I cannot start gmoccapy, it gives me some error on vfd.

So the question is are the setting correct for the serial port (ie baudrate, parity and so on) then the next hurdle is to get the command right that needs to be sent.
Also some VFD's need their serial interface enabled by setting the correct parameters.
Maybe try to swap the TX/RX lines
Setting up serial communication can be a bit of pain if there is no way to monitor what is happening on the line. Even worse trying to troubleshoot from afar.
[edit]
You seem to have used the VFD with the RS485 before so I guess the port settings and the vfd parameters should be ok and it looks like the component should take care of the command structure. Are you sure the RS485 to USB adapter works under linux?

This tells you that the pins from the hy-vfd component are created so the component is running but it is not seeing a reply from the vfd.

Many are using rs485 with VFD`s..
How can I swap TX/RX lines? (explain it to a non linux person)

It's the physical wiring, but that is likely also not the cause since, I presume, you are reusing the setup that has worked before.How can I swap TX/RX lines? (explain it to a non linux person
Have you checked if the RS485 adaptor is supported under linux?

Does not communicate with vfd. Plug rs485 in to windows 10 machine with mach3, works instantly..
