Who remembers the old dot matrix printers? ( I am showing my age on this one) You know the ones we used in college computer labs that required switching the printer to print from Computer A, Computer B, C or D. Am I getting a few nods?
So why not try this same concept for an iPad and computer? At the teacher station (hooked to a classroom overhead projector) often switching back and forth between the monitor and iPad can be a bit troublesome taking out the VGA cord from the computer and hooking into the dongel to display the iPad screen on the projector. I use the dongel below for the iPad2 to project on the screen.
In comes the "old school" data switch box. By switching from A to B, either the computer screen or the iPad screen is projected on the screen. Viola!
Simply place the VGA Cable from the computer to the I/O (input/output) of the data switchbox. Place the pictured cable below in the A or B and connect one to the dongel on the iPad and the other to the computer.
The data switch boxes typically come with 4 of these male to male end cables.
