I've successfully read data from EKM metering by using Python as in http://forum.ekmmetering.com/viewtopic.php?f=4&t=3472 link.
RS485 Serial Communication Between Arduino Mega and Arduino Nano With Visuino: Sometimes we need to connect Arduino boards located far away from each other. The RS485 is a very convenient way to connect the boards with just 2 wires, and can work to a distance of 1200m (4000 ft). The Qt Serial Port module provides the following examples for reference to help understand the API usage. Running the Examples. One direction songs mp3 download. To run the examples from Qt Creator, open the Welcome mode and select the example from Examples.For more information, visit Building and Running an Example.
Open PKG File A PKG file, diminutive of 'Package', is simply a package of installation files. These files are used by the Mac Operating System and are executed when a user wants to install a program or a software on the computer. The PKG file is similar to the MSI installation files used by computers running the Microsoft Windows operating system. Pkg File Opener free download - Instant File Opener, Winmail Opener, Free ZIP File Opener, and many more programs. The Apple PKG files usually contain installer scripts that are used by a variety of Mac programs for software installation purposes. The PKG files contain compressed installer files that are used to install Mac software applications onto a user's hard drive. Oftentimes PKG files will also be used to update NeXT installer packages. .pkg file opener for windows.
