UIO-HMI-24 Digital Inputs/Outputs & DAQ board with

39 channels and USB/Bluetooth/RF connectivity.

Welcome to the world of Computer Automation. This Digital Input/Outputs (DIO) Board - UIO-HMI-24

is a perfect companion for all your computer automation projects where you require large number of

I/Os as well as DAQ capability.

UIO-HMI-24 can be connected with USB / Bluetooth / RF to PC, laptop or

any Android device.( different models have different connectivity.) It has up to 39 digital & 8 analogue

I/Os that will help you to monitor various real world scenarios using switches & different kind of sensors to

monitor many parameters like Temperature, Pressure, Light, Touch, PH etc. This card is not only good for

monitoring various parameters but a perfect candidate for Data Acquisition & control applications.

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-HMI-24 very easily. Easy to use commands are available

to communicate with UIO-HMI-24 which handle various tasks like Controlling Digital Inputs & Outputs and

getting analog data etc.

The controller provides up to 39 digital input & output pins. It has also got up to 8 analog input pins

and up to 4 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 wether it is providing digital output or analogue output can be interfaced with

UIO-HMI-24 and monitored with the help of computer.

Installation -

1. First download the driver according to your OS from our download section at

http://iknowvations.in/downloads/.

2. Run the software and follow the instructions.

3. Connect the board to your PC, it should be recognized by PC as CH340 Serial COM Port.

We will see here the procedure for Windows. Up to windows 8.x you will need driver while

Windows 10 will recognize this as a simple USB COM port & will provide a COM port number.

You can check it in Device Manager window of your PC.

When you run the Windows setup program , you will get the following screen -

Press install button and it will install all

the required drivers and you are done !

Life is easy hereafter ! Just connect the board & start to explore the board.

Start any serial communication software like HyperTerminal, choose the COM port of your card,

make the setting 9600 8-N-1 and you are ready to go ! Enter some commands & the board will

dance to your tunes ! Yes !

Don’t make any sense ? Move to next page.
