* **Center Frequency:** The center frequecy should be set to the resonant frequency of the cell. The firmware will set the frequency of the green laser to the center frequency. It will set the frequency of the blue laser to the center frequency - 3 Hz and the red to the center frequency + 3 Hz. Must be an integer.
* **Center Frequency:** The center frequecy should be set to the resonant frequency of the cell. The firmware will set the frequency of the green laser to the center frequency. It will set the frequency of the blue laser to the center frequency - 6 Hz and the red to the center frequency + 6 Hz. Must be an integer.
* **Blue Laser:** The laser connected to pin 1.
