Figure 11. Alternate System-Level Block Diagram
above shows an alternate connection of data flow, with sensor data going directly to the transponder
(e.g. through RS-232 Port 1) and
control data separate (e.g. on RS-232 Port 0).
The physical sensors would be
, the difference of note is that
shows the sensors connected
directly to the transponder, instead of through the flight computer.
8.2 Input and Output Interfaces
8.2.1 Input Power
The unit is designed to operate from 10V to 38V, without requiring any change to the configuration. Thus, it can be
operated from standard aircraft 14V or 28V DC power bus. The unit is most efficient at 28V.
The unit has two positive power input pins, both of which must be connected. Additionally, both grounds must be
connected for power.
The input power interface includes common- and differential-mode filtering for EMC (conducted emissions and
conducted susceptibility). Additionally, ESD and transient voltage suppression (TVS) diodes, suitable for aircraft
electrical systems supplied by engine-driven alternators/rectifiers, or DC generators where a battery of significant
capacity is floating on the DC bus at all times. The input power interface also includes reverse polarity protection to
-60V max (non-conducting) and under voltage lockout for power input voltages below 9V. Lastly, the power input
interface is short duration operational for voltages between 38V to 63V typical, consistent with a Category B
device as defined in DO-160G § 16.0 Power Input.
