The electrical power is connected to the top (6 pin) connector located at the rear
side of PICO D, see Figure 2–8.
2.5.3 Digital control and status signals
2.5.3.1 Definition of the logical states
The digital control signals are defined with 0V (LOW) as ON/TRUE/active/able and
with 5 V (HIGH) as OFF/FALSE/inactive/disable.
IMPORTANT !
If the input signal is not connected its default logical state is 5V = disable.
2.5.3.2 Digital control signals
The digital logic control signals are used to enable (or disable) certain PICO D fea-
tures. The control signals could be either TRUE or FALSE. Carefully read paragraph
2.5.3.1 (Definition of the logical states) before connecting PICO D. The digital input
circuitry is shown in Figure 2–10.
