Thank you for the response, and I think I answered my own question. I just realized that the Logomatic does not employ a serial conversion circuit which is required to talk to a PC serial port. I'm assuming that an RS232 Shifter SMD, P/N PRT-08780 is all I need to accomplish this?
I believe all my settings are correct and matched, and the data file is created in UART mode but empty. I can see that data is not comunicating as the LED's do not flash during transmission, however, I know that data is being transmitted because I have an Acumen that sees and logs it with no problem. I've connected to both TXO and RXI, 0 and 1 pins on the Logomatic with the same results.
Am I correct to assume that a serial shifter will solve ALL my problems?
