hm I saw similar output from a FortiExtender Console when the baud rate was incorrect.
Also parity and stop bit could be a culprit.
Also keep in mind that the pins onboard usually are a TTL serial header so you will need a level converter like MAX232 between it and pc. Also you must connect GND.
VCC (Circuit Power) Pin only needs to be connected when the AP does not have any other power supply connected.
Also do not forget about crosswiring: rx pin on board needs to connect tx on the other side and tx on board needs to conenct rx on other side.

Look like your baud rate is not set correctly.
I tried all baud rate. No success. What can be different from normal console port ?
I trying to use these pins.
Why do have the AP open? Did you open a TAC case if you suspect an issue with the upgrade?
Why not ?
thanks.with TTL works ;)
Hi, I'm having the same problem.
I can already connect to the IAP, but I can't interrupt the boot.It gives the idea that it does not accept the press any key
