3.3.2 CONNECTOR PINOUT
The supplied connector and backshell is required for proper installation and operation of the
unit. The functions associated with the 26-pin high density D-subminiature connector are
identified in Table 3.1 below.
Note that for the -1 Indicator version of the unit (non-pitot/static), six of the MIO pins have
different capabilities. These are referred to as “Frequency Inputs” and are identified as three
separate pairs on pins 23/15, 24/25, and 17/26. Also described below as MIO #7/8, #9/10,
and #11/12. The functions of these pins are detailed further in Section 4.
