MK XXII EGPWS Installation Manual

3.3.13 Category 13 – Input / Output Discrete Type Select

Category 13 defines the input and output discretes not defined as part of any of the other Categories.

Appendix E Table E 3.1.13 defines the Input/Output discretes options and identifies the first MK XXII EGPWS version in which the option was available (see the Effectivity entry).

3.3.13.1 Instruction

1.Using Appendix E Tables E 3, E 3.1.13, and E 3.1.13-x, select the Input/Output Discrete Type number that matches the aircraft configuration, feature preferences and version (part number) being installed.

Note: Helicopter I/O Discrete options are Types 128 or 129. The difference is the Output Lamp format described below in section 3.3.13.3.1.

2.Record the ID number for the Input/Output Discrete Select number from Appendix E Table 5.3.13 under the Ident No. heading for Step (Category) 13 in Appendix E Table E 3. This number will be used for programming the configuration module.

3.Using the Input/Output Discrete Type number from Appendix E Table E 3.1.13 as “x”, theICD Table E 3.1.13-x.is used to determine the wiring interconnects, record it on Appendix A Fig A1-1, A1-2, and A1-3.

Note: When there are two discrete pin choices for the same pin function in Appendix E Table E 3.1.13-x, use only the one that matches the aircraft wiring (use only the +28V and 0V or the Ground and Open definitions).
