the flash card and loaded into the RAM whenever power is applied or the system
is otherwise rebooted). The code executes in RAM, and accesses information
stored in the flash memory, in the serial EEPROM, and on the flash card.
The serial EEPROM stores:
The serial number of each unit.
The current odometer and trip meter readings.
A copy of the deployment definition parameters (an additional copy of the
deployment definition parameters is stored on the flash card so that copies travel
with both the system and the data). The deployment definition parameters stored
in the serial EEPROM contain the last settings programmed by the operator.
AT8 Board and Flash Card
The AT8 board and the DOS/Windows compatible flash card are the physical
components of the MMP file system. The flash card plugs into a PCMCIA connector on the AT8
board, which is connected directly to the address, data, and control bus of the TT8v2. After a
deployment, remove the flash card from the MMP and plug it into to a PC to transfer the binary
data files. Serial transfer of the binary data is useful during training and bench testing, but to
transfer the large volume of data from an actual deployment, remove the flash card to transfer the
files to a PC.
IMPORTANT
Remove or install the flash card only when the system is off, or by using the “hot swap” utility.
See Chapter 7, “Rev C Electronics Board User Interface” and Chapter 8, “Data Offload,
Processing, and Interpretation” for more information.
MMP Unpacker Program
The MMP Unpacker application (for firmware versions 3.01 and higher) can be used to
unpack the binary deployment data files to ASCII text. For information about this application, see
the section “Unpacking and Translating the Binary Data Files” in Chapter 8 of this User Manual.
For firmware versions below 3.01, binary files can be translated into ASCII text files by the
program PDP-N_NN (see Appendix , “Unpacking data using PDP-N_NN.EXE” in this User
Manual.
