Method and apparatus for providing two way control and data communications to and from transportation refrigeration units (TRUs)

摘要

An RS-485 bus is directly connected to transportation refrigeration unit sensors for transmitting information from the sensors to a remote location and for controlling sensor parameters from the remote location. The GENSET associated with the transportation refrigeration unit also utilizes the RS-485 bus, in which the bus is directly connected to the GENSET sensors for bi-directional communication therewith.
