User Options
The PCA ships in a state that enables immediate evaluation of the
analog-to-digital converter (ADC). However, you can reconfigure various
options through hardware. This chapter discusses these options to ensure that
any reconfiguration is conducted properly.
The hardware on the PCA falls into various groups:
18 jumpers
4 wire links
2 resistors
1 momentary push switch
Table 3
1 lists jumper options, a brief description of each function, and
information on where the option can be found.
