Hi all,
my first post because i am totally stuck. I am using linuxcnc for years now, but only with absolute basic functionalities with axis gui. In the past weeks i started to do more configurations and "exploration" on advanced topics. i switched to gmoccapy and implemented "automated tool length sensor" successfully. Now i am working on the connection between my VFD and linuxcnc over modbus (rs485).
i did a lot of "research" and tried a lot of things. I found the integrated HAL-driver wj200_vfd, i belive my omron mx2 and hitachi wj200 are the same vfds. i ordered 2 RS485 adapters for my pc. one usb<->RS485, and one RS232-RS485. i tried a lot of different hal-entries. but whatever i try, it ends up with the attached screen.
Can someone give me a hint how to track this error? How can i test the rs485 adapter? how can i check i data is "flowing" thru the 2 lines between adapter and vfd?
greetings
Andreas

Is the driver finding the dongle?
I think we need a bit more data. If you press the "Select all" button in the dialog box then you can copy to the clipboard with Ctrl-C and paste into this forum or a text-document with Ctrl-V.
Then we might be able to better see what is wrong.

Hi,
i got it working after starting from the beginning again. Finally it was ...a big shame.....serialport in bios was disabled.
But at all, i didnt get the wj200-driver to work with the usb-rs485 dongle. But with the rs232-rs485 adapter it works fine now! i am happy and now i fight with the next topics (hal configuration). i open another thread for this.
Thx for your reply, although it was my stupidity.
