I also had some problems with initial tests, it seems that when the =
DSP10 board is first tested stand alone (not connected to DSP board) =
outputs from U108 can be random. With a lab power supply which has a low =
rising voltage at power on, I could see both 10R and 10T on. With a =
clean 0 to 11V transition things are back to normal, 10R and 10T are =
both at zero, my understanding is that U108 must be controled by the DSP =
code to give either 10R or 10T.
