P7-13 Main CDI + Right
P7-14 Main CDI + Left
P7-30 Main GS + Up
P7-31 Main GS + Down
Each deviation output provides
±
150 mV full scale and is capable of driving up to a 200
Ω
load, (i.e. up
to a maximum of five 1k
Ω
loads connected in parallel).
2.8.2.2 TO / FROM Output
P7-11 Main CDI + FROM
P7-12 Main CDI + TO
The TO / FROM output provides
±
250 mV and is capable of driving up to a 200
Ω
load, (i.e. up to a
maximum of five 1k
Ω
loads connected in parallel).
2.8.2.3 Flags
P7-10 Main CDI + Valid
P7-29 Main CDI - Valid
P7-28 Main GS + Valid
P7-32 Main GS - Valid
Each flag output pr300 mV when valid information is present and is capable of driving up to a

Ω
loads connected in parallel).
2.8.2.4 Superflags
P7-9 Main GS Superflag
P7-27 Main CDI Superflag
Each flag output provides (V
in
– 2) volts relative to ground when valid information is present, where V
in
.
represents the aircraft power supplied to the GNS 480. Each output is capable of supplying up to 400
mA.
2.8.2.5 OBS Resolver
The OBS resolver input should be compatible with a standard 6-wire OBS interface -
any electrical zero crossing will work because the GNS 480 will calibrate out any errors.
P7-7 OBS_ D {S1} (COS input high)
P7-16 OBS_ F {S4} (SIN input high)
P7-24 OBS_H {R HI} (Reference output high)
P7-25 OBS_C {R LO} (Reference output low)
P7-26 OBS_E {S3} (COS input low)
P7-34 OBS_G {S2} (SIN input low)
