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!
We recommend to use this 12VDC Power Supply Adaptor (SYS1357-2412) that may be found also in our store. Please contact with us if you have questions. We sell the adaptor with one of the AC plugs for: USA, UK, EU, AUS. It is sold separately !
Bellow is given shortcut for instructions how to connect the device DAE-RB/Ro8-12V + DAEnetIP3-ET or only DAEnetIP3 - EX for first time to router with UTP cable. In the user's manual are shown the rest connection types.
- Connect DAEnetIP3 RJ45 port with UTP (doesn’t matter crossover or straight) cable.
- Connect PC with the other side of the UTP cable.
- Change the IP of the PC. It may be for example 192.168.0.1. (DAEnetIP3 is with 192.168.0.100).
- Supply DAEnetIP3 with power supply 12 VDC (the middle pin of DAEnetIP3 power jack is +12VDC). The power led (with red color) must be on.
- Open your browser (IE, Firefox, Opera) and type 192.168.0.100 in the address bar.
- Use admin for password.
- Open admin settings.
- Change the Eth IP address of DAEnetIP3. Make it to be in one network with your router and PC. For example if your router is with IP 192.168.0.1 and PC with 192.168.0.101, make DAEnetIP3 with 192.168.0.100. Eth mask must be 255.255.255.0 and Eth gateway 192.168.0.1 (router IP)
- Click “Save” button.
- Unplug the power supply.
- Disconnect the UTP cable from PC and connect it to the router.
- Supply again the DAEnetIP3
- Open browser and type 192.168.0.100.
- Now you may access the DAEnetIP3 controller with router via router from PC.
Typical connection of the device
16 x Digital outputs
DAEnetIP3 has 16 digital outputs working in 19 different modes. However the relay board has only 8 relay outputs. So to set the relays you need to change PortA.0 - PortA.7. Relay1 is connected to PortA.0, Relay8 to PortA.7. On the PCB this is marked as PortA_1. When the output level is 0, the relay is OFF. When it is 1, the relays is ON.
8 x Digital outputs
DAEnetIP3 has 8 digital inputs. They work with +3.3V logic (Low level is 0V, high level is 3.3V). They work in 3 different modes. When the controller digital inputs pins are not connected the pins are in high level (there is connected pull up resistor 10K to each digital input). The input may be tracked only, may control some PortA digital output (this means the relay board also) by rising/falling edge or it may control even output from another DAEnetIP3 controller (connected in the same Ethernet network).
8 x Analog inputs
DAEnetIP3 has 8 analog inputs with 2.5 VDC reference voltage source and 1024 bit resolution.
The input may be tracked only, may control some PortA digital output (this means the relay board also) by crossing threshold or it may control even output from another DAEnetIP3 controller (connected in the same Ethernet network).
It is possible also each analog input to be linearized (i.e. to be retreived directly desirable units).
Access via 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 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

Access via Web
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 (Ajax).
Access via HTTP API commands
Bellow are shown example commands. Please note that there is HTTP API password (by default it is admin) to prevent unauthorized access.
send: http://your.ip.address/command.html?P=admin&ASG=?& (get the whole PortA status of DAEnetIP3)
receive: <!DOCTYPE html><html><body>ASG=0F0F;</body></html>
send:http://your.ip.address/command.html?P=admin&ASG=?&BVG=?&CV0=?& (send several commands at a time)
receive: <!DOCTYPE html><html><body>ASG=FFFF;BVG=0F;CV0=12;</body></html>
Access via 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)
Each DAEnetIP3 controller may be accessed via UART serial communication. The protocol is given in the documentation. This is provided in case you need RS485 network for example accessed only with one IP address. Each controller has serial address, that is given in each packet sent to the server bridge from user software. The figure below to the text shows how 3 DAEnetIP3 controllers are connected in serial network using UART <-> RS485 convertors (not included in the auction). The serial network may be accessed over LAN, WLAN or WAN with user TCP/IP socket based software.
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.
