Conditioned ERASE CVR INPUT A
series discrete input to the 12­bit ADC
converter. The discrete state is determ­
ined as high or low by comparison to in­
ternally programmed thresholds. Refer­
enced to the Signal Ground.
Not Used. Conditioned DATA LINK VAL­
ID shunt discrete input to the 12­bit ADC
converter. The discrete state is determ­
ined as high or low by comparison to in­
ternally programmed thresholds. Refer­
enced to the Signal Ground. Circuitry not
populated on the AI PWA. Input remains
pulled high on the AI PWA.
Conditioned PUSH TO TEST shunt dis­
crete input to the 12­bit ADC converter.
The discrete state is determined as high
or low by comparison to internally pro­
grammed thresholds. Referenced to the
Signal Ground.
