I did not cut any wires in my Humviewer - just settings
This part I understand...there would be no wires in Humviewer ...(Humviewer just reads the data in the B000"x" channel files and displays the data in Humviewer in the correct format in the user chosen pane in Humviewer...(the "HB recording" B0000 file contains 1 of the 2d frequency data - the B0001 file contains the 2nd of the 2d frequency data)...

My confusion is in how the 385c DI unit is recording the return signal from the left SI piezo (in the Compact SI xducer)...with the signal actually coming thru the 385c DI unit's 2d channel...

Echo data is echo data as far as the piezoes in the xducer are concerned...

But as soon as that return echo data enters the 385c DI unit...the processor takes over and "processes" that data into the correct image format (2d or DI image format)....as dictated by which "wire channel" that echo data came thru from the pin configuration in the back of the 385c DI unit....

So as soon as the return echo data (from the left SI piezo in the Compact SI xducer)...hit the female 2d socket in the back of the 385c DI unit...the 385c DI unit should process that echo data as a "2d image format"......

Then...when all the B000"x" files are transferred into Humviewer....Humviewer should interpret that data as coming from the unit 2d channel and display the data as "2d data" in the Humviewer "2d pane"...not the Humviewer "left SI" pane (as is showing in your sample Humviewer pix)...

Dang...wire channels I can usually grasp ...but this 1 has me stumped...(but I do enjoy a challenge in my brain circuits)...
