I doubt it, at least I couldn't find such an option. It is a cheap knockoff of Saleae Logic. The signal seems to regularly toggle at more than 8MHz, which the logic analyzer cannot capture, resulting in 'framing errors'.Does your logic analyser have a state option? With that it is only concerned with state transitions rather than sample rate.
I get:What did you find with the multi-meter? I would expect UART to meter like this...
Made some progress with information gathering. The connector definitely connects to RS232 pins on the microcontroller. Apparently,You could try tracing the pins back to see what they are attached to.
Now I need to figure out what kind of converter might be required for this and how to build it. Any input is appreciated!The interface levels [need to be?] converted to the levels necessary for the operation of the [microcontroller] by an external converter.
