CMU NO. 2 NOT INSTALLED
(2) When individually wired to the zero state, configuration pins TP12G and TP12H
indicate, respectively, that the inputs designated for CMU No. 1 and CMU No. 2 (pins
MP1G/MP1H and MP3G/MP3H, respectively) are connected to an ARINC 429
source of CMU information (e.g., CMU label 270 and SAL 304), and also the single
SDU output (pins MP1J/MP1K) is wired to the appropriate CMU(s). The SDU only
logs/reports/indicates bus inactivity on either CMU input bus if the respective
configuration pin indicates the bus is supposed to be connected to an ARINC source.
The SDU can assume (for functional purposes) the presence of the CMU
connections from the state of these configuration pins.
R. MCDU/WSC No. 1 thru No. 3 Configuration
