Access DAEnetIP2 v2 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 v2:

Select device DAEnetIP2v2. 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-daenetip2v2

Control via web browser

In order to access your DAEnetIP2 v2 controller from browser, your web browser have to supports javascript. Just write the IP address of the controller in the address bar and you will see the page, which is integrated in the controller (it has small built in server). The default username/password are admin/admin. Control P5.7 and P5.8 pins.

I/O Ports control/monitor

Traps/P5 control. DAEnetIP2 v2 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 v2 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:

http://admin:admin@device.ip.address/iochange.cgi?ref=re-io&01=00&02=FF

admin:admin are the username:password

device.ip.address is the DAEnetIP2 v2 IP address (by default it is 192.168.1.100)

01=00 is the state of P3 DO

02=FFis the state of P5 DO

For example:

http://admin:admin@192.168.1.100/iochange.cgi?ref=re-io&01=00&02=FF

The i/o states (P3, P5, P6) can be retreived by sending this HTTP command:

http://admin:admin@device.ip.address/ioreg.js

it will be received javascript file with several variables and one of them is:

var IO=new Array (0xFF, 0xFF, 0x80, 
0x00AB, 0x0049, 0x0118, 0x014A, 0x012F, 
0x003E, 0x0029, 0x01DD)

Bytes 0 and 1 are the digital I/O states (in hex format)

Bytes 3...10 are the Analog inputs values (in hex format)

For example:

http://admin:admin@192.168.1.100/ioreg.js

Control DAEnetIP2 v2 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.
