Hello
Can someone please be so kind and take a look at my setups and guide me in a better direction.
I've managed to fry already 2 computers without understanding the cause of it.
I gave my best to visualize the setup. Both times it has also fried the USB to RS232 coverter. Everything else seems to remain functional and undamaged.
Prior to connecting I have tripple checked the polarities and voltages and everything has been in order.
I have had no problems by running the optiplex on 19.5v with stepdown buck from the 24v battery source for many weeks straight. Right after connecting the touchscreen the pc was dead in 5-10 sec. Is the problem here trying to combine 12v and 24v power sources together in such way?
Thanks in advance!
