A. BITE System The BITE system is assembled into the MPES. The Cabin Intercommunication Data System (CIDS) (Refer to 23-73-00) commands the MPES to go into the BITE mode. All input audio channels at the Main Multiplexer (MM) 8MK are electronically isolated from an active processing. A 400 Hz test tone is put on each of the channels. At the Seat Electronic Box (SEB) 100MK/ Passenger Control Units (PCUs) 200MK and 201MK all channels are examined for correct operation. Any failure data is transmitted back to the MM, the CIDS and the Central Fault Display System (CFDS) (Refer to 31-30-00).
B. PES Power Test When the PES power is on, the BITE automatically starts. Maintenance persons operate this test on command from the Programming and Test Panel (PTP) 110RH. An ARINC 429 high-speed bus transfers data between the CIDS and the MPES.
C. Audio Audio signals from the audio reproducer 10MK, and video audio, supply a minimum of eighteen audio channels to the MM. Circuits in the MM process this analog input and prepare it for conversion to digital data. These are sent to the SEB through the Wall Disconnect Boxes (WDB) 50MK.
D. Audio Output The SEB changes the MM digital audio, back to its original analog form. This audio output is transmitted to the passenger headsets through the Passenger Control Units (PCU).
E. Channels The audio signals in the MM can give a stereophonic channel. One monophonic channel from the Compact Disk (CD) reproducer is programmed as the left channel; the other monophonic channel is programmed as the right channel. Two monophonic channels give the effect of one stereophonic channel. Four channels from the CD reproducer can be used to provide boarding music over the loudspeakers in the cabin and in the lavatories.
