What are you trying to do?
Update the PCB’s TM, PM, UI and so on like shown in the French manual?
So, you have such “Equalis” hardware or you just use this manual as a guide to whatever board you have??
If it’s another board you have why not using the manual of that board in the first place???
I see one difference between the manual and what you are doing, don’t you??
On the other hand, I’m not familiar with Flip software, so not sure if it makes a difference.
But when you provide a manual I suppose one need to follow it correctly, right?
Settings\Communication\you select RS232 while the manual shows CAN\IXXAT
Then in the "Controller Area Network Setup" window you have the RS232 frame active while it’s greyed out in the manual.
Like I said I’m not the specialist here… … …
But: One never knows how a cow catches a rabbit ?!!?
