Configuration
The default settings of the detector meet most application needs. These settings
can be customized to meet additional requirements. Customizing the Nano
detector requires changing the settings of the eight segments of the
configuration DIP switch (Figure 12) mounted on the main PCB. See Table 4
below and the paragraphs following the table to determine the proper switch
setting for the application.
