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.
2. THESE CONNECTIONS FOR KX165 OR KNX80/81 PREVENT THE RECEIVER
FROM FLAGGING THE NAV SIGNAL WHEN THE RESOLVER IS BEING USED BY
THE GPS. CONSULT THE APPROPRIATE KING DOCUMENTATION FOR
FURTHER INFORMATION.
3. SEE ARINC-429 INSTALLATION PAGE WHICH DOES NOT REQUIRE THE
RESOLVER SWITCHING RELAY (WHERE APPLICABLE)..
4. 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.
5. CHECK MANUFACTURERS DOCUMENTATION FOR ANY ADDITIONAL
INSTALLATION SPECIFIC RELAY POLES WHICH MAY ALSO BE
NEEDED.
6. 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.
