E6
Discrete_Input7
I
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.
G5
Discrete_Input8
I
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.
F5
Discrete_Input9
I
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.
E5
Discrete_Input10
I
Not Used. Conditioned shunt discrete
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. Circuitry not populated
on the AI PWA. Input remains pulled
high on the AI PWA.
G4
Discrete_Input11
I
Not Used. Conditioned shunt discrete
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. Circuitry not populated
on the AI PWA. Input remains pulled
high on the AI PWA.
F4
Discrete_Input12
I
Not Used. Conditioned shunt discrete
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. Circuitry not populated
on the AI PWA. Input remains pulled
high on the AI PWA.
