3.2.1.1 OBS/Resolver Selection (Rs I)
Selecting the OBS input to the unit using the configuration pages has 3 options:
SER:
Serial input: The unit accepts the OBS over the RS-232 input and changes the deviation
outputs accordingly with the inputted data.
RES:
Mechanical Resolver: The unit uses the analog resolver inputs to determine the OBS and
changes the deviation outputs accordingly.
INT:
Internal OBS: The NAV 2000 changes its display, eliminating the standby frequency and
memory access to allow for direct input of the OBS. In this mode, the Volume knob
becomes the OBS Control, and frequency input is directly inputted through the frequency
knobs (Right Hand inner and outer). The display shows a digital CDI, however this is not
to be used for IFR flight. In order to allow for IFR flight, an external CDI/VDI
MUST
be
attached to the unit.
3.2.1.2 Resolver Test (Rs T)
The resolver test option has no functions. In this setting, the information following the: represents the
currently received data from the mechanical resolver. If the bearing being displayed is incorrect, select the
Resolver Calibration setting (RsCl) and calibrate the NAV 2000 to the attached head.
3.2.1.3
Resolver Calibration (RsCl)
The resolver calibration option has two settings, No and Yes. When initially selected, No will be
displayed. Calibration of the NAV 2000 to the resolver is as follows:
•
Set the Resolver OBS to 150.
•
Rotate the inner left knob to “Yes”
•
Push the left knob.
•
On success, the display will show “Cal”
•
If there is an error, the display will show “Err”
If the result of “Err” is received, check your wiring between the mechanical resolver and the NAV 2000
3.2.1.4
Serial Mode (SrMd)
The serial mode configures the RS-232 output to work either as a standalone navigation unit (DIR), or as a
slave to the COM 2000 to fully emulate the SL-30 (PAS). This setting has two options, DIR and PAS.
•
DIR: Direct serial. The output directly connects to an EFIS or other serial device.
•
PAS: Passthru. The output connects to a COM 2000 before connecting to an EFIS or other serial
device.
3.2.1.5
VOR Calibration (VORC)
The VOR Calibration setting allows for the user to calibrate the VOR settings and has two settings, No and
Yes. When initially selected, No will be displayed. Calibration of the NAV 2000 VOR is as follows.
•
Have a VOT or VOR calibration device available.
•
Channel the unit to the selected frequency and verify reception (The CDI will unflag)
•
If the calibration device has a bearing select, set it to 0.
•
Rotate the inner left knob to “Yes”.
•
Push the left knob.
•
After 1 minute, the unit will display either “Cal” indicating a successful calibration or “Err”
indicating an error.
If the result of “Err” is received, verify reception of the test frequency and operation of the antenna.
