Here, the operator can change the data directory path if necessary, and enter data to be written to the datafile headers including bias voltage, text comments, and channel bitmask info. The user can also control fake data generation, turning it on and off and entering the fake data word written to file. Each time the <Accept> button is clicked, the datafile path, bias volts, and bitmasks are written as a new line to the VetoCFG.txt file. Each time the main VetoDAQ application starts, it reads the last line from the VetoCFG file, so these entries are persistent through restarts. The comments field is persistent between calls but is not written to file, so it will clear on restarts.
