NABU TTL Serial Adapter Mystery Solved!

I figured out why only the nabu.ca software has problems with this USB adapter.

    Good Job. Hopefully DJ gets to see this or if ever I catch him on chat I'll be sure to mention it.

    This is exactly why I (a) chose FTDI for my interposer, and (b) added a jumper that allows you to defeat it (and ties CTS to ground). 🙂

    When you connect to the RXD/TXD lines on the UART, did you account for back driving or are you connecting TXD, to RXD and RXD to TXD at the UART?

    I don't understand the question. What back driving? How else would one connect it?

    Is it possible to disable the com port flow in the driver config in device manager. I know this can be done on Linux.

    That's an interesting idea. I was going to test it, but when I put my NABU back after this last round of experiments, I changed to using an RS-422 to Ethernet adapter and ran all the cables "once and for all", including stapling them into place. So it has become too much of a hassle to pull it all out again.

    Does this issue relate to why some Dtech connection allow the slideshow to run for 11 hours straight, then using the same Dtech connection, the slideshow might only run for an hour? I've had the issue with my Dtech where slideshow test runs great, then sometimes stops after an hour. Haven't been able to nail down the inconsistent performance.

    Not this specific issue, this was particular to non-Dtech adapters, and prevented them from communicating at all (it is fixed now BTW). But if it's a cable issue, interference comes and goes so it's possible you're getting occasional bit flips when your neighbors are using the microwave. But there are so many variables, who knows. Your NABU could have a flaky capacitor somewhere and dropping out the voltage at random times, or there could be bugs in the software.

    I bought the cheaper DTECH adapter with a CP2102 chip, and the Internet Adapter software sits at "Init mode" and nothing happening on the NABU, just as you describe. Is this the answer to why my device isn't working?

    It's possible, or it could be any other problem that causes the same symptoms. An easy check is to try the Internet Adapter software from www.nabunetwork.com/resources/software-downloads/, or nabud, both of which are known not to have the CTS/RTS problem.
