Connecting it all together:
 

1. Installing the software on your target computer is the first step needed. Be sure the program operates without any errors and contact us if there are any problems. See the F.A.Q.S first. Disable any unused programs, screensavers, virus detectors that will interfere with the operation of the bell program. After all, if this is a stand alone computer, not connected to the www, then they won’t be needed.
2. Make the computer operate the Timer (Multiple Switching's) software as soon as it reboots. See the F.A.Q.S about this. This is to ensure that if the power goes off and on, the program restarts.
    
3. Connect the relay board with the RS232 cable and test with the software to make sure the relays are operating correctly.
    
4. Now it is time to connect in permanent. Find a suitable location for the computer, relay board and power supply. Remember this computer will be on all the time. The monitor only needs to be on during adjustment to the program times.
    
5. Install the cables, bells, horns or buzzer, and wire in to the relay board.
    
6. Power up you system, adjust the times, days for each channel, and sit back and relax.
    
7. Purchase the software.
    
8. Email us if you want to about the system you have installed, your location, and what you think of the Timer (Multiple Switching's) software for our Testimonials section.
