Section 2 Installation Considerations
2.1 INTRODUCTION
The SAE5-35 Altitude Data System simplifies installations that include GPS, Terrain Awareness
Systems and other avionics that require RS232 altitude input information. The SAE5-35
provides standard Gillham Grey Code output on its 15 pin connector. Grey code is required
for interface to Mode C ATCRBS and Mode S transponders. Two independent RS232
outputs are provided on the nine pin connector. The SAE5-35 also incorporates SANDIA
aerospace’s exclusive Altitude In-flight Monitoring (AIM) feature that advises pilots if they
deviate from their selected altitude by more than one hundred feet. The AIM feature can be
installed by purchasing SANDIA aerospace’s optional annunciator/switch assembly, P/N
305217-00. Or the installer can supply his own switch and annunciator assembly(s). The
main 15 pin connector follows the standard encoder interconnect used by many manufacturers.
By following this convention, upgrading to the SAE5-35 is made easier. If another
manufacturers encoder is being replaced, it is important to check the wiring information
before plugging the existing connector into the SAE5-35. Both the Grey Code output and
each of the RS232 outputs have separate drivers. This ensures that a load on one line does
not load the other. Additionally, the RS232 output is available even if the enable line on the
Grey Code has not been enabled by the transponder.
The SAE5-35 does not require warm up unless the outside temperature is below 20 degrees
C. When warm up time is required, the internal heater is capable of warming the SAE5-35
from -20 degrees C to operating temperature in less than two minutes.
2.2 MOUNTING CONSIDERATIONS
The SAE5-35 can be mounted in any axis and either inside or outside the pressure vessel.
Mounting should allow for as short a pressure line as possible from the encoder to the altimeter.
Be sure to allow an ample service loop on the cable to allow for calibration of the
SAE5-35
CAUTION: DO NOT mount the SAE5-35 in
the direct airstream or near either the hot or
cold air ducts.
2.3 COOLING
The SAE5-35 does not require external cooling.

3.1 GENERAL
The SAE5-35 is supplied with a mounting tray and solder type mating connectors. It is important
that proper solder techniques be observed in attaching wires to the mating connectors. Failure to do
so could result in a failure in the connection and cause intermittent or non operation of the SAE5-35.

3.3 MOUNTING TRAY INSTALLATION
The mounting tray is mounted to the airframe using either three or four number 6-32 screws. The
mounting hole pattern for the SAE5-35 mounting tray contains five holes. For new installations, it is
recommended that the four corner holes be used to mount the SAE5-35 tray. The fifth hole has been
added to facilitate upgrades from other manufactures encoders. Refer to the SAE5-35 tray dimensions
in Figure 3-1 to determine if the hole pattern of the removed system match the hole pattern of
the SAE5-35 mounting tray.
8 305186-00
3.4 STATIC PORT CONNECTION
A standard 1/8 - 27 NPT brass fitting is provided on the front plate of the encoder for attaching to the
aircraft static air system. An adapter may be used to convert this to match the aircraft static plumbing.
When attaching the mating fitting, make sure that it is secure and free from leaks that can induce
errors in the static system. In installations where an existing encoder is being replaced, the existing
tubing and fittings should be examined for any damage or deterioration and replaced if necessary. To
reduce the likelihood of the brass fitting rotating while installing the static lines, a “D” shaped hole is
used to mount the brass fitting into the front panel. Upon completion of installation of the SAE5-35, a
Case Leak test is to be performed per FAR Part 43 Appendix E
NOTE: Since significant force can be applied to the encoder
during static fitting installation, dual wrench techniques are always
recommended to avoid damage to the encoder.
3.5 ELECTRICAL INSTALLATION
The SAE5-35 is designed to operate from 11-32Vdc without any special wiring considerations.
Power can be supplied from the transponder’s switched A+ output, the transponder circuit breaker or
from the aircraft buss. If supplied from the aircraft buss, the line must be protected with a 2 amp fuse
Figure 3-1

or circuit breaker. SAE document AS8003 Minimum Performance Standard for Automatic Pressure
Altitude Reporting Code Generating Equipment states that “a means shall be incorporated in the
equipment to indicate the loss of electrical power or the effect thereof, unless the electrical power to
operate the code generating equipment is supplied by an ATC Transponder which also supplies an
indication of this power loss.” This is typically accomplished by using the switched A+ output from
the transponder or by connecting the SAE5-35 power input to the transponder circuit breaker. Alternatively,
the two power pins, 8 and 14, are internally connected in the SAE5-35. Only one of these
connections is necessary to supply power to the unit. The unused connection can be used to drive a
panel-mounted indicator if desired.
All transponder functions including the Grey code output are on the 15 pin connector J4. The RS232
digital outputs for GPS and other avionics requiring this format as well as the AIM function are on
the 9 pin connector J5. The Grey code output on the transponder is disabled whenever Mode C on
the transponder is not selected.
Note: The RS232 serial data output is always present whenever
there is power to the SAE5-35 and the warm up time is completed,
even when the Strobe/Enable line is not grounded.
Note: If power is supplied from the transponder, the RS232 and
AIM functions will be inoperative when the transponder is turned
off or removed from the aircraft.
Grounding the Strobe/Enable line on J4 pin 6 will enable the transponder Grey code data. There are
three methods used to do this.
1. Permanently grounding this line.
2. The transponder provides a switched ground enable signal.
3. The transponder provides a strobe-ground enable signal.
The SAE5-35 is compatible with all three systems, refer to the appropriate transponder installation
manual for detail. Interconnect information for the most popular transponders can be found in Figure
3-6. For other makes of transponders, refer to the manufacturers installation manual.
Note: If the transponder being interfaced has a strobe output,
the AIM function will not operate properly and should not be
connected.
While several manufacturers use RS232 digital altitude data, their formats and baud rates may vary.
The SAE5-35 can accommodate most data formats by either grounding or leaving pin 4 on J5 open.
If pin 4 is left open, the output baud rate is 9600. If pin 4 is grounded, the output baud rate is 1200.
The RS232 interconnect information can be found in Figure 3-7.
Interconnect information for the most popular transponders can be found in Figures 3-6. The RS232
interconnect information can be found in Figure 3-7.

The SAE5-35 uses Sub-D solder cup connectors with screw lock assemblies. Proper wire attachment
and assembly of the screw locks and connector hood are shown in Figure 3-2 and 3-3. It is recommended
that each wire and solder cup be covered with a piece of shrink tubing or other insulator.

4. See Figure 3-5 for AIM function interconnect wiring.
305186-00
3.6 CALIBRATION
The SAE5-35 is calibrated at the factory to a pressure datum traceable to the National Bureau of
Standards. However, when the encoder is installed in the aircraft it must be recalibrated to correspondence
to the primary flight altimeter, refer to FAR 91.217 and FAR 91.413 for details. This
calibration ensures that the altitude code generated from the SAE5-35 is within 125 feet of the altitude
displayed to the pilot.
3.6.1 Equipment Required
1. A calibrated pitot-static test set capable of pumping the system from –1000 feet up the
maximum test altitude.
2. A calibrated transponder ramp tester capable of displaying the encoder altitude information.
15
3.6.2 Calibration Procedures
Note: The Primary Flight Altimeter must be calibrated per
part 43 section E. Verify compliance with AC-43.13 as applicable.
1. Connect the pitot-static test set to the aircraft static system. The SAE5-35 must be
connected to the aircraft static line near the flight altimeter and the two altitude adjustments
buttons must be accessible. Apply power to the altitude encoder and the ATC
transponder and allow the encoder to stabilize. Set primary flight altimeter to 29.92
inches of mercury.
2. Apply vacuum from the pitot-static test set to obtain an altimeter reading of 34,800 feet
(or 100 feet below the maximum test altitude specified in Part 43, appendix F.)
3. Slowly increase altitude and note the flight altimeter at the encoder transition point. If the
transition point is not 34,850 +/- 30 feet (or between –80 feet and –20 feet below the
maximum test altitude), press the increase button (behind slot A) or decrease button
(behind slot B) until the encoder transition point is within tolerance.
4. Increase altitude to obtain an altimeter reading of 35,000 feet (or 100 feet above the
maximum altitude specified in Part 43, appendix F.)
5. Slowly decrease altitude and read the flight altimeter at the encoder transition point. Verify
the transition point is 34,950 +/- 30 feet (or between 20 feet and 80 feet above the maximum
test altitude.) If necessary, press the increase button (behind slot A) or decrease
button (behind slot B) until the encoder transition point is within tolerance.
6. Apply pressure from the pitot-static test set to obtain an altimeter reading of -800feet
7. Slowly decrease altitude and read the flight altimeter at the encoder –800 foot to –900-
transition point. If the transition point is higher than -880 feet, hold the increase altitude
button (behind slot A) while pressing and releasing the decrease altitude button (behind
slot B) until the transition point is –850 +/- 30feet. If the transition point is lower than -
820 feet, hold the decrease altitude button (behind slot B) while pressing and releasing the
increase altitude button (behind slot A) until the transition point is –850 +/- 30feet.
8. Apply pressure from the pitot-static test set to obtain an altimeter reading of -1000feet
9. Slowly increase altitude and read the flight altimeter at the encoder –1000 foot to –900-
transition point. If the transition point is higher than -920 feet, hold the increase altitude
button (behind slot A) while pressing and releasing the decrease altitude button (behind
slot B) until the transition point is –950 +/- 30 feet. If the transition point is lower than -
16
980 feet, hold the decrease altitude button (behind slot B) while pressing and releasing the
increase altitude button (behind slot A) until the transition point is –950 +/- 30 feet.
10. Repeat steps 2 through 10 until the transition points and the flight altimeter are within
tolerance for both low and high altitudes. Verify several test points throughout the range
to assure correspondence between the SAE5-35 and the flight altimeter.
305186-00
3.6.3 Placarding
We recommend that the altimeter used for flight reference and the SAE5-35 be placarded with the
following information:
Replacement or re-calibration of the altimeter used for flight
reference requires re-calibration of SAE5-35 Altitude Encoder.
