Potentiometer
A 5k ohm, thumb-wheel type, potentiometer at RV1 provides variable resistance input for user
applications. The output is the result of a voltage divider that changes as the thumb-wheel is
turned. This device is connected to the MCU on signal PTA0. Table 5 below shows the user
jumper settings and user signal connections.
The potentiometer is not available while in monitor mode. When using the potentiometer the
user should requires removing USB-MON08 Enable jumper ‘D’ to disable the MON08 COM
signal. Otherwise, results may be unpredictable.
NOTE: User-5 option jumper must be removed to enter monitor mode.
NOTE: USB-MON08 ENABLE-D jumper must be removed to use this function.
Photocell
A photoconductive photocell provides light sensitive, variable resistance input for user applica-
tions. Device resistance is inversely proportional to light intensity incident on the surface of the
device. A rail-to-rail OP amp at U2 boosts the photocell output to useable levels. This signal
is available to the MCU on signal PTA1. Table 5 below shows the user jumper settings and
user signal connections.
NOTE: User-6 option jumper must be removed to enter monitor mode. The jumper may be
reinstalled after RESET.
