failure Huanyang VFD HY01D523B

I found that my HY VFD was ignoring parity settings so had to configure the driver to suit the VFD rather than vice-versa.

More details here: forum.linuxcnc.org/24-hal-components/292...-2-7?start=50#205997

Thank you again Andy for the follow up!
Well, today I wanted to know more about the VFD and its ability to communicate on the serial port.
So I downloaded a little software on a window laptop :    github.com/GilchristT/SpindleTalker2/releases  and after a few adjustments, I was finally able to start the spindle and vary its speed with my USB - RS232 dongle.
a little more reassured, I took the opportunity to check the baud rate: 9600

I read carefully the topic you quoted in which you had to adapt the driver to the VFD and I can't think of anything else to try:
Linuxcnc config identical to before the failure
VFD and its identical config 
the only things that have changed: 
the computer and the USB-RS232 adapter

I don't understand all the arguments you use in :

loadusr -Wn spindle-vfd hy_vfd -S 24000 -F 400 -n spindle-vfd -t 1 -d /dev/ttyUSB0 -p none -r 19200 -s 1 -g

and so I'll just copy the line over and replace my actual one which is 

loadusr -wn vfd hy_vfd -n vfd -d /dev/ttyUSB0 -p none -r 9600

with one change, I'll replace 19200 with 9600 (baud rate)
Does this make sense to you or am I wrong again?

The options are all listed here:
linuxcnc.org/docs/2.8/html/man/man1/hy_vfd.1.html

I think that I decided to set them all (or most of them)

I think that

-t 1

was important, and

-p none -s 1

Because the VFD was ignoring my parity / stop settings and so I had to make LinuxCNC match the VFD.

-g is there to give more feedback. I probably ought to turn it off now.

Well after a bit of adaptation to fit with my config (shown below)
loadusr -Wn vfd hy_vfd -S 24000 -F 400 -n vfd -t 1 -d /dev/ttyUSB0 -p none -r 9600 -s 1 -g
I get this result: 
Any idea ?


I played with baudrate, parity, bit stop, no change .
 

What is the current situation? Can you control the spindle via the link with Spindle Talker and not with LinuxCNC? Or does it not work with either?

Yes I can control the spindle via the link with Spindle Talker and not with LinuxCNC.

I get the below message through the console:

I've tried to to connect the cable with reversed polarity to check and the message is different (something like ERROR invalid crc received. I did not captured the whole message as I inverted again the wires to retrieve the initial (and right) wiring.
