The Government is conducting market research to identify potential sources that possess the expertise , capabilities , and experience to meet qualification requirements to produce theC - 5 Battery Control Electronics Module ( 6130 - 01 - 535 - 7275UC , P / N : 716110 - 2 ) C - 5 Edge Lighted Panel and Annunciator Dimmer Circuit Card Assembly ( 5998 - 01 - 599 - 8130UC , P / N : 716163 - 2 ) C - 5 Single Board Computer Circuit Card Assembly ( 5998 - 01 - 666 - 0869UC , P / N 4V10442 - 101A ) The National Stock Numbers ( NSN ) and Part Numbers ( PN ) are listed above : The BCEM is an aircraft component that is part of the Emergency Power System ( EPS ) on all models of C - 5 aircraft and provides means to charge the battery . In addition , it is used in conjunction with the auxiliary power unit ( APU ) system on C - 5M model aircraft . The Edge Lighted Panel and Annunciator Dimmer ( ELPAD ) Circuit Card Assembly primary function is to convert 28VDC ( Volts Direct Current ) to 5VDC ( Vols Direct Current ) for the C - 5 Aircraft . The Circuit card is a crucial component in aircraft instrumentation . The Single Board Computer CCA is common component to four ( 4 ) next higher assemblies . There is one ( 1 ) Single Board Computer CCA contained in the Communication / Navigation Panel ( CNP ), Cursor Control Panel ( CCP ) and Cursor Control Device ( CCD ) next higher assemblies . Two ( 2 ) identical single board computer CCAs providing redundant processing capabilities are contained in the Automated Flight Control System ( AFCS ) Panel next higher assembly . The CCA consists of an ARINC 429 communications interface and a 32 - bit processor . The ARINC 429 communications interface converts received serial data signals ( RX1 and RX2 ) from the line receivers into data that is usable by the 32 - bit processor . The 32 - bit processor receives commands to control serial communications and to convert the received data into column and row addressing signals . The column and row addressing signals are used by the Integrated Panel A1 to provide the appropriate display or light an indicator . Switch position signals from Integrated Panel are converted into digital data by the 32 - bit processor . The digital data is then transformed into serial data for transmission by the ARINC 429 communication interface CCA . The serial signal ( TX1 ) from the ARINC communication interface is applied through the line driver on the Interface CCAs to the aircraft .
