    Hi Michael,
    I see 2 possible answers here:
    1. Wrong baud rate. The initial X2M1000 data sheet states a 9600 baud rate. This is wrong. It should be 115200
    2. A line stuck at high or low. Did you try to look at the PSoC RX/TX lines with an oscilloscope? And did you use the TXB0104 level shifter? If so make sure the OE line is activated and that the line load is > 50kOhms, ref page 15 in the TI datasheet (http://www.ti.com/lit/ds/symlink/txb0104.pdf)

    Hi IngarH,

    Thanks for the response, turns out the error was on my part I was using the UART pins shared by the psoc programmer. Moving the pins resolved the issue.
