Block Diagram

Block diagram shown above is supplied by 12 or 9 volt from bus module. When the bus driver ON the power from the module, driver need to key in the bus number. E.g. (512). After the bus number has been key in into the module, the data will converted into analog data. This process called digital analog converter (DAC). This happen because we need to transmit the analog data into the VIPs module.

The analog data will transfer to the VIPs module by the antenna and will decode into digital data. This process called analog digital converter (ADC). VIPs will get the data from the decoder and buzzer or sound will announce the bus number. LED function is to indicate either the VIPs need to board the bus or not. The process be repeated until the VIPs confirms their bus.
