DacLadder, check JST connectors. May be I am wrong, but it is what I figure out from the photos....
I'll check it out, thanks. Kingwa responded to my Email about the DSP board's I2S header connector pinouts, connector pin pitch, and location of termination resistors.
The termination resistors for the external I2S RJ45 are located on the RJ45 connector circuit board mounted to the backplate. So if the RJ45 board is removed termination needs to be provided. I am referring to an OR5 type cable implementation. A substitute USB receiver board may need something totally different.
The pitch (distance) between I2S header pins is 2.54mm (0.1"). This eliminates a lot of guessing for finding header mating connectors.
The DSP board I2S header connector pinouts when facing the Master 7 front, left to right, are the following:
Pin 1 - GND
Pin 2 - SDATA
Pin 3 - SCLK
Pin 4 - WCLK
Pin 5 - MCLK
I need to get an oscilloscope on the current RJ45 I2S implementation. If the clocks look OK at destination then all this extra work is not necessary. That should happen in the next few weeks.
