MODULAR MINING DISPATCH SYSTEM (OLD DISPATCH SYSTEM) cntd• GPS receivers use a constellation of satellites and ground stations to
compute position and time of device almost anywhere on earth.• GPS module is for amplification of radio signal from external GPS
receiver in order to improve precision of navigation system, distance measurement, vehicle monitoring and recording when used together with internal GPS.• Inclinometer is for measuring slopes/tilt , elevation or depression wrt
gravity. Its connected to HUB by RS232 cable.
RS232 VS RF• RS232 cables are single ended serial interface.• RS232 use full duplex method of communication.• RS232 allows one transmitter and one receiver to be connected
together.• RS232 can transmit to a mx distance of about 50 ft at rate of 19.2
Kbps.• RS232 has a max data rate of 1Mbps.• RF cable are just coaxial cables that can be used to send radio freq
signals.
