It appears as a USB CDC ( Communications Device Class) device when connected to USB port of a
computer ( for USB based cards). This creates a Virtual Serial (COM) Port, which allows easy communication
with the card. Any programming language that supports serial communications ( C, C#, C++, VB, VB.NET,
Perl, Java etc) can be used to communicate with UIO-369 very easily. Easy to use commands are available
to communicate with UIO-369 which handle various tasks like Controlling Digital Inputs & Outputs and
getting analog data etc.

The controller provides up to 252 digital input & output pins. It has also got up to 40 analog input pins
and up to 35 PWM output pins.All pins will be individually configured as Digital Input or Digital output or
Analog input automatically as per input command on the fly.

Each Digital pin can support a TTL or Schmitt Trigger Input or a 3.3V output. Each analog pin will convert
analog voltage ( Between 0 to 3V) or Higher ( through voltage divider) into 10 bit resolution value. The
output can be raw data or converted into voltage. The raw data be converted into required form using
conversion formulas.

Any kind of sensor whether it is providing digital output or analogue output can be interfaced with UIO-369
and monitored with the help of computer.
