Emulating the EAM-R system includes detecting that data received from a sensor has been written to a memory block associated with the primary EAM-R board, and sending instructions to a secondary computing device to write a copy of the data to a same memory block in the secondary computing device that is associated with the secondary EAM-R board. The EAM-R system is emulated in an emulation system that includes at least one network connection. The emulation system does not include a physical primary EAM-R board or a physical secondary EAM-R board.
