C lADC
CLEAR AID
(A32, A34 TP603)
This signal is used by the A32 ADC 1 and the A34 ADC 2. CLADC is
from the ADC control ler to the ADC process switch. This signal is used
with GSW to determ i ne the input to the AID Converter
le.
When both
assemblies are i n stalled, the C LADC s ignal goes to the A32 ADC 1
assembly's process switch.

CONTROL OUT
(A32, A34 TP504)
This line connects the A32 ADC 1 to A34 ADC 2. T h is con nection
determi nes whether the A32 analog digital converter or the A34 analog
digital converter is i n control. If an assemb ly'S CONT I N is either high
or floati ng, it is i n control. If A34 ADC 2 is plugged in, the CONT I N
of A32 ADC 1 i s low and A34 ADC 2 ' i s i n control .
