/config 
      oct.txt  main config file, the line 'setupNum=' determines which setup to use.  A value of -1 indicates no hardware present
        a value of -2 indicates DAQ hardware, but no FPGA
        a value of 3 is for 200 kHz setup, and 4 for 50 kHz setup.  0 through 2 are for older configs currently untested
      *.txt  config files for audio, mirror, and FPGA, as indicated in oct.txt
