NOTES:
1. CONNECT OBS "H" FROM RECEIVER "H" or "C" WHICHEVER IS THE ACTIVE
OUTPUT. CHECK APPROPRIATE NAV RECEIVER SCHEMATICS. CONNECT
"SIN OUT" and "COS OUT" TO THE ACTIVE RETURN PINS, USUALLY D/F.
CONNECT "OBS VREF" TO EITHER STATOR RETURN PIN (REF OR GROUND)
USUALLY E or G. THE LOAD RESISTOR SIMULATES A SYNCHRO.
4. CHECK MANUFACTURERS DOCUMENTATION FOR ANY ADDITIONAL
INSTALLATION SPECIFIC RELAY POLES WHICH MAY ALSO BE
NEEDED.
2. THE APPROACH ACTIVE OUTPUT FROM THE GPS TO THE AUTOPILOT MAY
HAVE TO BE AN ADDITIONAL RELAY. SEE THE MANUFACTURERS
INSTALLATION DIAGRAMS.
5. KLN-90B PINOUTS SHOWN. CERTAIN CONNECTIONS SUCH AS
GPS_DISPLAYED AND OBS/LEG ARE SPECIFIC TO KLN-90B.
7. FOR 3V COMPOSITE NAV SOURCES INSERT A 470K SERIES RESISTOR
LOCATED AT THE SN3308 CONNECTOR. NOT REQUIRED FOR .5V
SOURCE.
1 MASTER: SN3308 CONTROLS THE GPS (PREFERRED)
2 SLAVE: EXTERNAL GPS SWITCHING CONTROLS THE
SN3308.
3. THE PREFERRED INSTALLATION IS THE SN3308 P3-3 CONTROLLING AN
EXTERNAL SWITCHING RELAY. IF AN EXISTING SWITCH CONTROL BOX IS
INSTALLED AND IT IS DESIRED TO LEAVE IT OPERATIONAL, USE SN3308 P2-30
TO SENSE GPS MODE. THIS WILL DISABLE THE NAV SOURCE SWITCH AND
CHANGE THE SN3308 MODE TO GPS-1 WHEN ACTIVE. YOU MUST ENABLE
P2-30 AS THE GPS SENSE INPUT IN THE SN3308 SYSTEM SETUP PAGE.
6. MSG AND WPT ANNUNCIATORS ARE COMMUNICATED ON THE ARINC 429
SERIAL CHANNEL.
8. ON 14V AIRCRAFT A PULLUP RESISTOR MAY BE REQUIRED TO
ALLOW VOR OPERATION.
