FIGURES 6.10.10-1 MKVI/MKVIII EGPWS SERIAL I/O
6.10.10.1 Data Loading Interface Formats
The data loading may be accomplished by using the PCMCIA (Smart Cable) interface.
6.10.10.2 General Operation/Protocols
The EGPWC will look for a valid Data Load RTS (Ready to Transmit Signal) continuously (at a specified period) while the
aircraft is on the ground. Once a valid Data Load RTS is detected/received the EGPWC will acknowledge the request (as
necessary) and then prepare/wait for the uploaded data. As the data is being read from the load source, the EGPWC will
unlock the flash memory and overwrite the existing flash memory data locations (corresponding to the uploaded data files).
