12-5. Dipswitch settings
The 510 Indoor shares the computer board with the 510 Outdoor.
There are two banks of dipswitches (upper and lower bank) on the
computer board. The upper bank has certain special functions as
shown on the following table and generally should not need
adjustment. Carefully verify the functions of each dipswitch before
changing any settings.
