4.5.2 Configurati on 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 VI/VIII Interface
Description Document (Appendix E), document number 060-4314-401.
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 associated ID is read from the
Configuration Module and listed on the PC display. Alternately, when not in the Configuration sub-mode, the
command “PS<Enter>” (Present Status) will display the EGPWC and Configuration Module data.
7. Configuration Module reprogramming is complete.
4.6 Terrain Dat abase Loading
4.6.1 Effectivity
The MK VI EGPWS (965-1180-0XX and 965-1190-0XX) are shipped from the factory loaded with the Regional
Terrain Database requested when the purchase order was placed. Use (operation) of a MK VI EGPWS outside
of the loaded Regional Terrain Database will result in the Terrain Awareness function being unavailable. Aircraft
operating outside the loaded Regional Terrain Database region will have to load one of the other two Regional
Terrain Databases before beginning the ground test.
