CDI (GNS 530 Only)
Selection Description
GPS
The GNS 530 CDI button is in the GPS state, and the GPS
ANNUNCIATE output is active. This annunciator output may be
required to be active for some installations.
VLOC
The GNS 530 CDI button is in the VLOC state, and the VLOC
ANNUNCIATE output is active.
GPS Only The GNS 530 CDI button has been disabled.
NOTE
If it is desired to disable the GNS 530 CDI key, press MENU on the MAIN CDI/OBS
CONFIG page and select “Ignore CDI key?”. This causes the field above the CDI key to
always display GPS, regardless of CDI key presses. This may be necessary for certain
EFIS systems where navigation sensor selection must be accomplished on the EFIS or its
control panel.
OBI SOURCE (GNS 530 Only)
Selection Description
Always GPS
The MAIN King Serial OBI outputs are always GPS. This is useful if it
is desired to switch a Bendix/King KI 229 or KNI 582 RMI pointer
independently from the GNS 530 CDI button.
Track CDI The MAIN King Serial OBI outputs are GPS or VOR, and switchable
by the GNS 530 CDI button. This is useful if it is desired the
Bendix/King KI 229 or KNI 582 RMI pointer to display the same
navigation source as the GNS 530 CDI outputs.
VERT CDI
Selection Description
Flag Up
The vertical deviation bar is parked in the full-scale up position when
GPS or VOR navigation is selected for output. The exception is when
the CDI is in VLOC mode and an ILS frequency is tuned, in which
case the vertical deviation bar is parked in the centered position.
Flag Center The vertical deviation bar is parked in the centered position whenever
it is flagged.
