Application examples

1. It may be used for controlling electrical devices remotely. Just connect a relay board to the digital outputs and control up to 16 electrical devices. You may create timers and pulses. You may look at our store for high quality and low cost relay boards. Also we sell kits DAEnetIP3 + Relay board.
2. It may be used for monitoring sensors. DAEnetIP3 has 8 analog inputs with 10 bits resolution that may be used for tracking sensors (for temperature, humidity...)
3. It may be used for simple event alarm. When some event is detected by th einputs, DAEnetIP3 may generates alarm signal.
4. It may be used for simple standalone web based thermostat. A temperature sensor may be used for controlling relay based on low and high threshold. All these parameters may be set easily by the user from the web interface in seconds.
5. It may be used as standalone PLC. Each input or time event may control each output. Different modes can be easily adjusted by the user. With several click you may turn the controller in powerful PLC, that usually costs many times the pirce of DAEnetIP3.
6. It may be used as TCP/IP to Serial Bridge (Serial to TCP/IP bridge). You may controll many DAEnetIP3 controllers in one RS485 network only with one IP address. When access the bridge controleler, it resends the commands to the rest over the serial RS485 line. When the destination controller receives the command, it sends answer and the bridge DAEnetIP3 gets this answer and send it over the IP network.

7. It may be used for I/O Distributed System. Simply adjust the controllers settings and the inputs of one controller may control the outputs of another over LAN or WLAN. No extra PC or software, just use router and LAN or WLAN connection. Some examples for possible connections are given bellow. Note that on the figures there are DAEnetIP3 controllers with and without Wi-Fi interface.

Typical connection of the device

Power Supply

Please pay attention that:

• The middle pin of the power jack is +12VDC
• There is not protection against reverse voltage.
• We recommend to use power supply adaptor that outputs 12 VDC stabilized.
• Inproper power supply voltage will damage the device !

Virtual Serial Port

DAEnetIP3 and all devices that are based on it may be accessed/controlled via Virtual Serial Port. In other words the the device in this auction may be accessed via COM Port RS232 commands from your computer because it will apear as COM Port:

• DAEnetIP3-Ex appears as VSP (COM Port) on your PC
• It may be accessed with any Serial Terminal (for exaple HyperTerminal)
• The only thing the user has to do is to send and receive commands via the COM Port. All the TCP/IP commnucation is done by the driver.
• There is not matter if your DAEnetIP3 device is connected to your PC over LAN cable or Wireless Wi-Fi network, it will appear as VSP (COM Port) on your PC. You need to set only the proper IP, Port and COM Port Name.

Example commands and responses that are sent/received via the DAEnetIP3 VSP (COM Port). The serial address of DAEnetIP3 is 00.

• Get Digital Input 1 level (Din1), counting in the commands is zero based:
  • Send: 00BV0=?;
  • Receive: 00BV0=0; //The level is low
• Get Analog Input 1 level (Ain1), counting in the commands is zero based:
  • Send: 00CV0=?;
  • Receive: 00CV0=512;
• Set Digital Output 12 (Do12) in High level, counting in the commands is zero based:
  • Send: 00ASB=1;
  • Receive: 00ASB=1;
• Get the Ethernet IP address of the module.
  • Send: 00MIP=?;
  • Receive: 00MIP=192.168.0.100;

All the commands are described in the  DAEnetIP3 user's manual

.NET Visual Basic Express 2010 example for access DAEnetIP3 with serial RS232 commands.

We from Denkovi Team provided free open source Visual Basic Express 2010 example. It is demo application and serves to help you building your own software for accessing the DAEnetIP3 based device via Serial Port commands. You may download the project from - here. The .exe file is here

 We created also detailed tutorial how to control DAEnetIP3 (or DAEnetIP3 based device) via Serial Port commands. There is also step-by-step guide how to create Virtual Serial Port. Please see it - here

16 x Digital Outputs

DAEnetIP3 has 16 digital outputs port. This port is called Port A. Each output line has pull-down resistor 10 Kohm to GND. The low level is 0V. The high level is 3.3V. Each digital output channel may be adjusted independently to work in one of the 19 modes for example just by several clicks from the drop-down web lists. The modes are listed below: 

8 x Digital Inputs 

DAEnetIP3 has 8 digital inputs port. This port is called Port B. Each output line has pull-up resistor 10 Kohm to 3.3V. When the input is not connected, its state is high (1). Each input may work in one of the 3 modes listed below:

DAEnetIP3 has 8 channel analog input port (8 x ADC). The reference voltage is 2.5VDC and each channel is with 10 bit resolution (1024). The port has digital filter for avoiding the interferences. Each analog input may work in one of the 5 modes listed below:

• Simple reading - This mode is simple reading of the analog input value. There are no reactions (events) based on this input. It is used only to retrieve the values from the analog inputs.
• Low - In this mode the threshold for events is the Low Threshold.
• High - In this mode the threshold for events is the High Threshold.
• Acc - In this mode the threshold for events are the Low and High Threshold.
• Low/High - In this mode the threshold for events are the Low and High Threshold.

Access via Web

DAEnetIP3 has built-in web server for configuration. All the parameters can be accessed via web browsers like Mozilla, IE and Opera. The pages for I/O ports are refreshed automatically. In this way it is possible to track all the I/O states in real time without manually refreshing the page. The web browser must support JavaScript.
The page below the text shows the page for the analog inputs. Their states are automaticaly refreshed each 2-3 seconds. The user doesn't have to click refresh button each time but just tracks the I/O changing values almost in real time.

Access via command line (Telnet)

DAEnetIP3 can be easily accessed via Telnet. Simple password protection mechanizm is provided. Note that Telnet is not secure protocol, so it is recommend using only in secure networks.

On the figure right to the text is shown how DAEnetIP3 controller with IP address 192.168.1.50 is accessed via Telnet with Windows XP.

• Open command line and type: telnet "Controller IP"
  
• Use the passowrd, in our case this is admin. After correct login the controller responds with welcome message.
• The first command is ASG=0000; - it sets all 16 DO in low level.
• CV0=?; gets the ADC channel 0 value. Its 415; It may be from 0 up to 1023.
• BVG=?; gets the eight digital inputs levels. Its 00, which means all inputs are in low level
• ASG=FFFF; Sets all the 16 DO in high level.

Ofcourse these commands are only small part. The full list may be found in the documentation.

Access via Serial Line (UART or RS485)  

Access via TCP/IP socket

DAEnetIP3 controller has possibility for access via TCP/IP socket. The user may connect with custom software to port that is defined for socket based TCP/IP communication.
The protocol is not based on some standart, but it is developed especially for the DAEnetIP3 controller. The full description of the protocol may be found in the user manual.
The reason for creating such communiation way is that TCP/IP sockets are widely used in all programing languages.In this way you may create software for DAEnetIP3 without learning difficult and heavy protocols.
The controller supports RC4 encryption/decription for the TCP/IP socket comunication. This is security measure that gives you basic protection.
Another security option is IP address protection, that allows only one IP to access the DAEnetIP3 via Web, Socket and Telnet.

Software examples

There are developed several small open source applications to show you that it is very easy to communicate with the DAEnetIP3 controller. They are for now in Visual Basic 6 and Borland C++ Builder 6. The examples show TCP/IP socket communication with DAEnetIP3. It is possible to read analog/digital inputs and control the digital outputs. All the rest parameters can be accessed the same way. Note that for get the examples work you need to turn OFF the RC4 encryption of DAEnetIP3. The examples does not provide RC4.
