E4 Discrete_Input13 I Conditioned shunt discrete input to the
12bit ADC converter. The discrete state
is determined as high or low by compar
ison to internally programmed
thresholds. Referenced to the Signal
Ground. No circuitry exists on the AI
PWA to support this signal.
H5 Ethernet_RN4 I Standard IEEE 802.3 Ethernet input.
Referenced to the Ethernet_RP4.
H4 Ethernet_RP4 I Standard IEEE 802.3 Ethernet input.
Referenced to the Ethernet_RN4.
H7 Ethernet_TN4 O Standard IEEE 802.3 Ethernet output.
Referenced to the Ethernet_TP4.
H6 Ethernet_TP4 O Standard IEEE 802.3 Ethernet output.
Referenced to the Ethernet_TN4.
B4 FDR_DATA_IN_HI I Standard ARINC 573/717/747 FDR Data
high input. Referenced to the Signal
Ground.
B3 FDR_DATA_IN_LO I Standard ARINC 573/717/747 FDR Data
low input. Referenced to the Signal
Ground.
A4 FDR_DATA_OUT_HI O Standard ARINC 573/717/747 FDR Data
high output. Referenced to the Signal
Ground.
A3 FDR_DATA_OUT_LO O Standard ARINC 573/717/747 FDR Data
low output. Referenced to the Signal
Ground.
F8 fpga_discrete_Output0 O 3.3VDC CMOS output pulled high to 3.3
volts by default. The CMOS low voltage
output, V
OL,
does not exceed 0.4VDC.
The signal controls an NFET gate hav
ing a 0.7VDC minimum voltage input
threshold. The NFET implements a
shunt discrete output assigned to CVR
MAINTENANCE FAULT. Referenced to
the Signal Ground.
E8 fpga_discrete_Output1 O 3.3VDC CMOS output pulled high to 3.3
volts by default. The CMOS low voltage
output, V
OL,
does not exceed 0.4VDC.
The signal controls an NFET gate hav
ing a 0.7VDC minimum voltage input
threshold. The NFET implements a
shunt discrete output assigned to DATA
LINK FAULT. Referenced to the Signal
Ground.
