Scientech TechBooks are compact and user-friendly learning platforms to provide a modern, portable, comprehensive and practical way to learn Technology. Each TechBook is provided with detailed Multimedia learning material which covers basic theory, step by step procedure to conduct the experiment and other useful information. With the rapid progress in computer technology and their applications, these computers can be used as dedicated controllers for a variety of uses: turning on/off lights or other devices around the home, office, laboratory or factory come to mind. All that is needed is the interface to connect it to the real world.
Scientech TechBook 2305 provides both the hardware and the software to do this. 2305 is a unique TechBook which controls 8 electromechanical relays using parallel port of Personal Computer. Each relay is switched on or off by output data (8 bits) sent by the parallel port of the computer. The software provides a graphical user interface to control relay operations, their control sequences with LED indication and simulations.
