Abstract
A site system for remotely monitoring and controlling portable machines is provided which includes a single channel radio frequency network. At least one portable machine has a microcontroller for controlling operation of the portable machine, a plurality of sensors for supplying machine operational data to the microcontroller, and a radio frequency transceiver unit. The radio frequency transceiver unit communicates with the microcontroller, and with the single channel radio frequency network. At least one host computer has a radio frequency transceiver unit. The host computer communicates with a predetermined portable machine by data transmissions on the single channel radio frequency network. A radio frequency protocol controls radio frequency data transmissions on the single channel radio frequency network.
