J1939 signal generator

J1939 signal generator is a high-level communications protocol, which operates on a Controller Area Network (CAN) Bus. This is useful for the development of the SAE J1939 reader. It can work independently on a PC, without additional software. Eight PGN/SPN data can be manually calibrated for each potentiometer, in two sets. It defines the data priority, size, scaling, and offset. A MIL indicator is provided for displaying the DTC status, which can be triggered by a switch. The standard goes on to define many other aspects, including message timeouts, how large messages are fragmented and reassembled, the network speed, the physical layer, and how applications acquire network addresses. J1939 simulator compliant vehicle signals are suitable for connecting PCs, smart phones, and tablets.
