Device Switching Using PC’s Parallel Port

On running the program  SRC_CODE.C the menu appears as shown below, asking for the operation to be done.

The very first option shows the list of the loads that could be controlled using this software along with their codes.

The outstanding part of this software is activating of required PROFILES at once so that the burden of controlling of individual devices is eliminated.

The activation of night profile is as shown below. We can even set the user defined profiles.

As a basic requirement the control over individual devices is also provided. If the user by mistake tries to switch ON the device which is already ON, the software detects it & the corresponding message is displayed.

The software also allows the user to know the current status of the loads.
