DAEnetIP2 I/O Ports
|"Free" - the pizn is free and defined for the user.||"XXXXXX" - the pin is reserved||"In" - the pin is input||"I/O" – digital input or output depending the settings||"Out" - the pin is output||"Ain"– analog input|
For inputs, if the input voltage exceed 3.3V, the controller may be damaged. If you have questions how to use the I/O ports please contact with us or take a look into the manual.
Here are the steps (instructions) how to power on and connect the device directly to your computer (see this image). For router LAN connection (see this image) or Internet connection, please see in the user manual:
1.Connect the DAEnetIP2 controller with your computer via UTP crossover cable. (note that the device does not support AUTO MDIX).
2.The flat ribbon cable connector must be fitted into to DAEnetIP2 IDC in this way
3.Connect each "In" labeled wire into the referred screw terminal of the relay board. For example "In 1" wire goes into Relay 1 In screw terminal, "In 2" wire goes into Relay 2 screw terminal and so on.
4.Connect the GND wire of the flat ribbon cable into the GND screw terminal of the relay board.
5.Connect supply jack to DAEnetIP2. You will have to find suitable power supply adaptor. DAEnetIP2 minimal supply voltage is 7.5 VDC. The maximal voltage is 25 VDC. It is recommended the supply voltage to be 12 VDC but 24 VDC also will work (in case you have 24V relay board and want single power supply source). DAEnetIP2 doesn't have any protection against inverted supply voltage, so be careful. The middle pin of the power terminal is + Vcc (center positive tip polarity)
6.Connect the power wires to the relay board as it is shown on the image right to the text. It is possible to supply the DAEnetIP2 controller and relay board either with single either with 2 separate power supply sources.
7.Now you can power on the whole kit (for example plug the supply adaptor into the electricity network)
8.In case of success you have to see this when you power on the kit (the link led (top) is blinking and the bottom led by default shows the power on and it is constantly on)
9.Check if the relay board power led is on constantly
|10. The kit in working condition|
11.Open your LAN card network settings and save them, because next step is to change them.
12.Your initial computer IP should be in the device network range. So it is recommend to be 172.16.100.1. Mask 255.255.0.0. Gateway 172.16.100.1. Change them. There is lot of info in the net how to do it (for example a good link is this one)
13.Open web browser and type 172.16.100.2 – default username/password are “admin”/”admin”
14.Now you can access all the parameters via your web browser or software on your computer.

Access DAEnetIP2 from mobile devices
iOS App DAE-iModules
Android App DAE-aModules
The video bellow shows how you can control DAEnetIP2 based device - SNMP 8 Relay Board LM35DZ. Any other Denkovi Ethernet Device from this list can be acessed with same success from your iOS device via DAE-iModules.
Some useful information about DAE-aModules/DAE-iModules and DAEnetIP2:
- Select device DAEnetIP2. You must be sure the IP, UDP Port and SNMP community are correct, otherwise it won't enter into the device
- To connect and scale the analog inputs with sensors, please refer to this link: http://denkovi.com/connecting-analog-sensors-to-daenetip2.
Control via web browser
I/O Ports control/monitor
Traps/P5 control. DAEnetIP2 can send traps if some analog input changes its level bellow/above some threshold (Low/High).
The same logic can be used for setting one of the digital outputs port - JP5 according analog input port JP6.
HTTP API commands
DAEnetIP2 i/o lines can be controlled/accessed via HTTP API commands and basic access authentication is required to do that.
The digital outputs (P3 and P5) can be controlled by sending this HTTP command:
var IO=new Array (0xFF, 0xFF, 0x80, 0x00AB, 0x0049, 0x0118, 0x014A, 0x012F, 0x003E, 0x0029, 0x01DD)
Control DAEnetIP2 via command line
Net-snmp is free command line utility for windows which allows you to execute snmp commands from command line, BAT files, BASH scripts or any other sofwtare that can execute external .exe file or commands from command line. The instructions file how to install net-snmp and example commands can be downloaded from here.

Please use DAEnetIP2 rev.2 firmware files only for DAEnetIP2 rev.2 modules and old DAEnetIP2 firmware files only for old DAEnetIP2 modules! The old and new firmware files are not compatible as there is hardware change from rev.2.
|Release Date||Firmware Version||Hardware revision||Mib File||Update Utility||Version History||Note|
|Nov 2017||6.28||DAEnetIP2 rev.2||Here||DAEnetIP Burner||Version History||Instructions how to update are in the User's manual or at this link.|
|Feb 2013||First hardware revison||Here||DAEnetIP Burner||Version History||Instructions how to update are in the User's manual or at this link|
|08 Nov 2017||
From 08 Nov 2017 we start shipping DAEnetIP2 with minor hardware changes (rev2). The new hardware is designed in a way to keep the compatibility however there are still small changes:
On the picture below it is shown how does it looks like the DAEnetIP2 rev2 module. You will see on the bottom side label with text "Rev. 2" which means that is DAEnetIP2 rev2 module, otherwise you have the old DAEnetIP2 module.
Some examples are not public, and the download links will be sent to your email after purchase or by request.
