Apollo CNX80 Installation Manual
Figure 3-5 - Resolver Calibration Page
The CNX80 cannot drive multiple resolvers at the same time. It is not recommended that external resolvers
be switched through a relay or other means because the resolver must be calibrated to the radio as
described in this procedure. If multiple resolvers are desired in the installation, the primary unit must be
installed and calibrated as described here. The secondary unit should use the composite output.
NOTE
The composite output is limited to the VHF Nav signal and will not be switched to GPS
when the
CDI
bezel key is pressed.
3.2.1.4 Baro
Interface
The Baro Interface function lets you to select whether or not a baro-correction potentiometer is installed,
and allows an installed potentiometer to be calibrated. It also provides an option to disregard the baro
correction and baro-corrected altitude from an FADC, which may be desirable in certain installations.
While on the Ground Maintenance SETUP menu page, press the
BARO
line select key. Press the top line
select key to toggle between INSTALLED (for installations with a baro pot) or NOT INSTALLED (for
installations without a baro pot). Press the
FADC
line select key to toggle between USE (for installations
where the baro data from the FADC will be used) or IGNORE (for installations where the baro data from
the FADC will not be used). The Baro Interface setup page is shown in Figure 3-6.
NOTE
Due to priorities of incoming data (refer to 2.5.2.3), the FADC baro data will be used
before that of the MX20. If it is desired not to use the baro-correction feature of the
FADC source, the FADC BARO/ALT setting should be set to IGNORE.
The units that are used may be set using the
UNITS
line select key to toggle the units between inches Hg
and millibars.
NOTE
Changing the units will only affect the units displayed during calibration. The user can
change the units that are displayed during normal operation via the system configuration
page.
