Next to be covered is how to turn the module on and off. Click on the button next to the on/off options and four menu items will appear: Always on, Analog on, Digital on, and Analog or Digital on. The default is analog on which allows the module to be controlled using an external enable signal. Now change this to Digital on. Notice that the “On” checkbox at the top of the settings list is not checked, but the module is still running. This is because the new configuration still needs to be written to the module, which is done by clicking the “Write Settings” button.
