Thank you for the reply Daz, and the offer to help

I now have what appears to be a successfully flashed and converted ST to DAP-link.
 

Now I am at the point where I need to hook this newly converted DAP-link to the NVEM controller. Is there a wiring schematic somewhere or something that tells me which pads on the controller get which wires? The pads are not labeled on the controller.
 

Here are the photos of how to connect to the board. Please note that the microcontroller gets the 3.3v from the board thus you need to power up the board with 24v when uploading the firmware

Thanks for the pics, that is just what I needed to know.

At this point you had said to follow the instructions above, but those look to be for the EC300. Are they all the same files or are there different ones for the NVEM?
 

Thank you for the quick reply.

The log you shared is from the Python script, but the important part happens on the EC300 board side.
Could you connect an RS232 interface and check the board's response when receiving the new configuration?

Thanks

I seem to of been wrong about converting the ST-link to DAP. I just went back and watched the video again and there were originally 2 steps in doing the conversion, but there is the post below that video - forum.linuxcnc.org/18-computer/44828-rem...rd?start=2050#321860 - that says to just use that one file?

I am now very confused and the computer says the converted ST link is an unrecognized device and it does not show up. I can not communicate with the link plugged into the USB

At this point I truly do not know what to do.

I can do it, but I need to get hold of a USB to RS232 adapter first. Should have it next week

It might be easiest to buy one for a few $$ on Amazon or Ebay.
