DCA1000EVM: Final part of capture card configuration in DataCaptureDemo_xWR.lua

Hi,

I would really like to understand the the last part of the capture card configuration in the DataCaptureDemo_xWR.lua script. In particular the following lines:

if (ar1.CaptureCardConfig_Mode(1, 2, 1, 2, 3, 30) == 0) then
....
 
--Start Record ADC data
ar1.CaptureCardConfig_StartRecord(adc_data_path, 1)


--Trigger frame
ar1.StartFrame()

This code happens between lines 193 and 219. My questions are:

Q1) What are all the parameters of ar1.CaptureCardConfig_Mode(1,2,1,2,3,30) specifying?

Q2) Is ar1.CaptureCardConfig_StartRecord(adc_data_path,1) connected to "RECORD_START_CMD_CODE"?

Q3) Is issuing ar1.CaptureCardConfig_StartRecord(adc_data_path,1) the same as pressing the capture_start hardware button on the board i.e. will it start streaming ADC data down the LVDS lines?

Q4) Is ar1.StartFrame() a command to the IWR1642 or something for the capture board? If the mmwavedemo OOB code is on the IWR1642 I presume this command would be irrelevant?

Thanks
