MULTIPLEX READ CODES (cont)
6–8
The drive system transmits transmission oil pressure transducer excitation data, NGB oil pressure and
temperature status, and transmission oil temperature status to the fire control computer (FCC) via the multiplex
data (MUX) bus system. Integrated in the MUX bus system is the FD/LS. FD/LS utilizes the MUX bus system DEK
(ADC) or CDU (ADD) for FD/LS command initialization and/or FCC memory read code accessing.
