Vor/Ils Discrete Inputs (Gtn 650 Only); Vor/Ils Indicator (Gtn 650 Only) - Garmin GTN 625 Installation Manual

5.2.15 VOR/ILS Discrete Inputs (GTN 650 Only)

VLOC REMOTE TRANSFER*
An asterisk (*) following a signal name denotes that the signal is an Active-Low, requiring a ground to
activate.
This input is considered active if either the voltage to ground is ≤3.5 VDC or the resistance to ground is
≤375. This input is considered inactive if the voltage to ground is 11-33 VDC or the resistance to ground
is >100kΩ.
5.2.15.1 VLOC REMOTE TRANSFER*
The VLOC REMOTE TRANSFER* discrete input may be used to flip-flop between the active and
standby NAV frequencies. A momentary low on this pin will load the standby NAV frequency into the
active NAV frequency field.

5.2.16 VOR/ILS Indicator (GTN 650 Only)

5.2.16.1 VOR/ILS Indicator Function
NOTE
Because the GTN 650 includes a "CDI" key that performs switching between GPS and
VOR/ILS on a remote indicator, it is seldom necessary to use these outputs to drive an
indicator. It is only necessary when it is desired for a separate indicator to display VOR/
ILS deviation full-time (regardless of the "CDI" key status).
The VOR/ILS indicator displays both lateral and vertical, To/From indications, lateral and vertical flags
and superflags. GTN 650 connector P1004 always outputs the VOR/Localizer/Glideslope navigation
information. The VOR/ILS pins on P1004 are used to drive an indicator that displays VOR/ILS
information at all times, regardless of the CDI selection on the GTN 650.
VOR/LOC COMPOSITE OUT is a standard VOR/localizer composite output signal which may be used to
drive the Left/Right, TO/FROM, and Flag indications of certain navigation indicators that contain an
internal converter.
The ILS ENERGIZE output becomes active when the VLOC frequency is channeled to a localizer
channel.
