UIO-HMI-24 39 Digital I/Os & DAQ Board User Manual /2
2 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 0 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.

All the channels will be in Output mode with 0 or Low outputs when power is first applied or connected to PC. 4/2
5 Command Reference -. For Digital Outputs - H00 - Set output of Channel 00 to or H igh. L00 - Set output of Channel 00 to 0 or Low. There are up to 39 digital Output channels on this card so it will be up to H039 or L039. 2. For Digital Inputs - I00 - Get Input value of Channel 00. I002 - Get Input value of Channel 002. There are up to 39 digital Inputs channels on this card so it will be up to I039. The value of input pins will be ( if it is High - 3 VDC) or 0 ( if it is Low - 0 V DC). The board will respond with 0 or depending upon the value at Pin. 3. For Analog Inputs - A00 - Get ADC value of Analog Channel 00. There are up to 8 Analog channels on this card so it will be up to A008. The resolution is of 0 bits so the input voltage ( 0-3V Dc) will be converted to 0 to 023 Decimal value or direct voltage value. 4. For PWM outputs - PX 0 to XY99 - PWM output of channel PX- from 0 to 99 % X can be one of,2,3 or 4 So P50 command will provide pwm output of 50% on P channel. Likewise P399 will output pwm signal of 99% on P3 channel pin. 4. Miscellaneous Commands - LED - Make on board LED ON. LED0 - Make on board LED OFF. BORD - Information about the board. VERS - Firmware Version Number. HELP - Provides list of commands Please note that all commands are sent in CAPITAL letters only. 5/2
6 Installation -. First download the driver according to your OS from our download section at http:///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 0 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- 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. 6/2
7 If you want to communicate with the card via HyperTerminal then start the HyperTerminal & set the COM values as per following screen shot. Set it to 5200 8-N-. Select the com port as per your connection to the card. Apply the power to the card. 7/2
