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-iModules/DAE-aModules and SNMP 8 Relay Board LM35DZ:

• Select device DAEnetIP2v2 or IP 8 Relay LM35DZ (V2). You must be sure the IP, UDP Port and SNMP community are correct, otherwise it won't enter into the device
• To scale the LM35DZ analog inputs in order to show temperature direclty in Degrees C, you must do the following settings for P6: Units: °C, Value at 0: 0, Value at 1024: 204
• To scale the LM35DZ analog inputs in order to show temperature direclty in Degrees F, you must do the following settings for P6: Units: °F, Value at 0: 32, Value at 1024: 399
• To scale the 0-10V analog inputs in order to show the value direclty in volts, you must do the following settings for P6: Units: V, Value at 0: 0, Value at 1024: 963
• To connect and scale the analog inputs with sensors, please refer to this link: http://denkovi.com/connecting-analog-sensors-to-daenetip2.

Access via software DRMv3

This device is supported by DRMv3 Software.

The device can be found in the device list under the default name: DAEnetIP2v2 IP 8 Relay LM35DZ

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

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

Control 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.
