SUBJECT:COMMUNICATIONS - CABIN MANAGEMENT SYSTEM - SOFTWARE CHANGE

BACKGROUND This change will make the cabin management system (CMS) operate with less problems. This change will make sure that passenger address (PA) announcements can be heard. The installed speaker drive module (SDM) software can cause some PA announcements to not be heard. The SDM will turn off the digital sound receivers if a chime occurs. The announcement has to be made again after the chime stops. The installed seat electronics unit (SEU) software can also cause some PA announcements to not be heard. The SEU can cause damage to some PA signals to the passenger control units (PCU). The PCU can accept the damaged digital signal as a different signal or reject the signal. The new SDM and SEU software will prevent these problems. New speaker volume adjustments are available in the new configuration data base (CDB). The optional volume adjustments will increase the PA announcement volume for the cabin attendants. This change will make sure all the passenger cabin functions of the CMS operate. One operator told Boeing that the zone management (ZMU) unit became unserviceable 11 times. The ZMU becomes serviceable when the ZMU power is turned off and then on. The installed cabin system control panel (CSCP) software and the ZMU software can make the ZMU not operate. This will occur if the signals between the ZMU and the CSCP are not synchronized correctly. The ZMU controls cabin lights, passenger signs, reading lights, attendant call lights and the cabin attendant control panels (CACP). These systems can not be changed if the ZMU for that area is not serviceable. The new ZMU and CSCP software will automatically start the ZMU again if the signals are not synchronized correctly. This change will supply better waste tank indication. The installed overhead electronics units (OEU) andZMU software can show the waste tanks empty after servicing. The waste tanks are 1/16 to 1/8 full after servicing. The software can also make the waste tank indication not show new data. This can occur if the waste tank logic control module (LCM) power is turned off momentarily. The new OEU and ZMU software will prevent these problems. A new waste tank chime is available in the new configuration data base. The optional chime will prevent chimes after servicing that are not necessary. This change will remove failure indications for the OEU that are not necessary. After a CSCP "QUICK TEST" or an "ALL TEST" the OEU can show an internal failure. The failure is shown for OEU's connected to a light ballast. The new OEU software will not cause an internal failure for OEU's connected to a light ballast. This change will make sure the CSCP display is seen when the CSCP is on. The installed CSCP software can cause the display to not be seen when the CSCP is on. This will occur if the CSCP power is off momentarily. Selections can be made on the CSCP when the display is not seen. The new CSCP software will make sure the display is seen when the CSCP is on. ACTION(PRR 61596) Remove the installed CSCP. Install a new CSCP. Make a new CMS configuration database. Install new operating system (OPS) software for the CSCP. Install new OPS software for the ZMU. Install new OPS software for the passenger address controller (PAC). Install new OPS software for the cabin interphone controller (CIC). Install new OPS software for the CACP. Install new OPS software for the SDM. Install new OPS software for the OEU. Install new OPS software for the SEU. Install the new configuration database.

The new configuration database is made by changing the installed configuration database. The configuration database generator (CDG) 285W0347-3 (disk set 285W0304-3) is used to change the installed configuration database. Do these steps to get the new database disk set: For BAB and UAL: 1. Convert the database. Refer to the 777 CDG User Manual section 1-7, "Opening an Existing Database" for the necessary instructions. NOTES: 1. Use disk number two of the installed configuration database disk set to get the necessary files. The "Read Only''' feature must be turned off to change the files. 2. The letters "CDB" are used to show the database was made at Boeing. Use different letters in the new database name. 2. Do a check of the new database. Refer to the 777 CDG User Manual section 4-51, "Task 5. Check the Database for Consistency" for the necessary instructions. 3. Remove any database "Critical Errors". Refer to the 777 CDG User Manual section 4-53, "Task 6. Correct Errors" for the necessary instructions. NOTE: "Warnings" are not "Critical Errors" and do not need to be removed. 4. Include the buyer furnished equipment (BFE) data. The BFE data will need to be converted. Refer to the 777 CDG User Manual section 4-56, "Task 7. Export to BFE" for the necessary instructions. Use the offline database generator (ODG) software shown below to make the BFE database files.
