DI5 and DI6 are connected to the Arduino board through a protection network. If you need
to bypass the protection network to use DI5 and DI6 as general-purpose input/output lines
(e.g. for I2C, 1-Wire or Wiegand communication), you can move jumpers J4 (DI6) and J5
(DI5) to the BYP position.
DI5-DI6 JUMPERS SCHEMATIC
Note that, with the jumpers in the BYP position, you should limit the maximum voltage
applied to DI5 or DI6 to the voltage levels accepted by the Arduino board installed in Iono
Arduino. Exceeding the Arduino voltage range will result in damage to the Arduino board
and Iono Arduino.
J1-J2 JUMPERS POSITION
Analog output
Iono Arduino features a 0÷10V output (AO1) which can be controlled by the PWM function
of the Arduino platform; the 0÷100% duty cycle of PWM signal corresponds to a 0÷10V
output voltage.
This is a sink/source output (the current direction at this output can be both positive and
negative).
