Notes:
1. The SAE5-35 has two independent RS232 outputs. RS232 TX2 can be connected to a
second sysytem in the same manner as RS232 TX1
2. The RS232 wires are 22 AWG twisted pair.
3. Shield grounds are ground at the SAE5-35 and open at the unit being interfaced.
4. See Figure 3-5 for AIM function interconnect wiring.

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 corre-
spondence 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 alti-
tude 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 informa-
tion.
