The GA-40/80 series of modules provide the DM-20 with an easy to configure panel
interface to its I/O channels. Switches (connected to the GA-40/80) provide user inputs to
the DM-20.
Similarly, LEDs (connected to the GA-40/80) allow the digital levels of the DM-20 to
display a variety of conditions.
