Keypad Interface
The OP7100 has a touchscreen, which is connected to the circuit board at
header J5. Header J6 is available for a customer-supplied keypad for the
OP7110.
Table 3-1 lists the pinouts for headers J5 and J6. The pinout for header J5
is identical to the pinout for header J6.
Figure 3-10 shows the location of headers J5 and J6.
