LOCOMM uses Microchip's PIC 16F877A series. Basically, device consists of two parts - a transmitter and receivers.
Data is transferred to the transmitter via Server Software. As soon as the transmitter collects the whole data from server, it is broadcasted through air to whole devices in coverage area.
A receiver, randomly receives any of the data transmitted through air and again basically, looks for start bit(s) of the possible message. Second step; determines if it is the receiver of the message by checking "TO" field of the incoming message. If not, cancels receival.
As the last step, if all the conditions are okay, the message is received and stored in device and displayed on the backlit LCD device.
