I want to make one master and three slaves. How can I set dip switch setting so that one can work as master and control the remaining three as slaves. Kindly please send me the instruction manual for dip switch settings for 1 master and 3 salves first. Also guide me what is the functionality of the dip switch. Is it something related to time or setting for master and slave. Please guide me as soon as possible so that I can place an order for my project.
