Modern agriculture equipment are more computer based today, and many equipments use a terminal in the tractor where the driver have the opportunity to make adjustments to the equipment. This is the reason why ISO developed a new standard called ISOBUS. It is a communication standard based on CAN specially adapted for griculture equipments. The purpose of the standard is that it should be ossible to equip a tractor with a standard terminal called Virtual Terminal that can be used to control the equipment. The use of the terminal should be independent of the manufacturer of the tractor as well as of the equipment.The purpose of this report is to ?nd a solution of how to use CC Systems on-board computer, CCP XS, as a Virtual Terminal. In the report both Hardware and Software requirements have been examined, but mainly the software requirements. Only one suitable software vendor, Vector Informatik, was found after contacts with different software suppliers. It have not been possible to test this package because of the high price for the evaluation license.A demonstration solution has also been developed in the project. It consists of a simulator program, that runs on a PC, connected to a CPP XS that executes a Virtual Terminal program. An ISOBUS compatible J1939 protocol stack from Ixxat Automation has been integrated in the Virtual Terminal program. It gives the opportunity to test the protocol stack on a CPP XS. In order to limit the size of the project, not all functions in the ISOBUS standard is implemented in the demonstration solution.
