4.5.2 Configuration Module Reprogramming
Reprogramming the EGPWS Configuration Module is accomplished similar to the programming
process above. Prior to reprogramming, the desired new configuration should be determined
based on the MK XXII Installation Manual (Appendix E), document number 060-4314-225.
For reprogramming the Configuration Module, the following procedure is used:
1. Verify EGPWC interface to P2 connector (including Configuration Module) and RS-232
interface to PC.
2. Power EGPWC and PC and start WinVIEWS.
3. With WinVIEWS active in the Terminal Mode, start the Configuration sub-mode by typing
“CFG” at the prompt (>). At this point, either all the ID’s can be rewritten using the CUW
command as before, or individual categories can be changed as follows:
4. At the
CFG >
prompt use the CAT command with the following structure:
- CAT<space><category #><space><ID#><space><T or F><Enter>
- <category #> is the Appendix E Category to change (example 7)
- <ID #> is the new ID to change to (example 92)
- <T or F> is True or False for rebooting the EGPWC. Use “T” if only one category is to be
changed and the EGPWC will reboot following <Enter>. Use “F” if another individual ID is to
be changed by another CAT operation.
Example: CFG > CAT 7 92 T<Enter>
5. After inputting the desired change information, pressing <Enter> will transmit the data to the
EGPWC to write to the Configuration Module. If a reboot is commanded (T), then the
EGPWC will reboot at the completion of the write process. If a reboot is not commanded (F),
then a message “Writing to configuration module … Category 7 ID updated
successfully.” is given and the CFG > prompt is again displayed. At this point the
Configuration Module has been changed, but the change will not be effective until the
EGPWC is rebooted. Additional changes can be made with the final change set to command
the EGPWC to reboot (or cycle EGPWC power to reboot).
6. Verification of the changes made is the same as before. As above, type “CFG” to restart the
Configuration sub-mode. At the CFG > prompt, type “CMR<Enter>”. Each category and its
