Hi, I need some help to upload screen data from NT31-ST123B-EV3 to PC using NT Support Tool version 4.8. I used USB to RS232 Female and make custom RS232 male to male according to this diagram. But it show no response. Can someone help me on this matter because I want to upgrade to NB HMI1000140595.jpg
 
Touch any two corners of the screen at the same time to access the system menu. Then select transmit mode.

Try several times, it can can be difficult. The touch areas are very small.

I already get access to the system menu. After select transmit mode what the next step. Btw, I use win 11 for this application
 
Then you open NTST and click Connect > Upload > Application. It's difficult to determine if you have a good serial connection so you should verify it with another serial device or perform a loopback test if you don't have success.

I just need to follow the DB9 pin assignment as per manual right?
