SECTION IV – CONFIGURATION MODULE PROGRAMMING AND
REGIONAL TERRAIN DATABASE LOADING
4.1 Introduction
The following procedures outline the steps necessary to accomplish a complete configuration of
the MK XXII EGPWS. This section must be accomplished in the order presented to minimize
errors in configuring and operating the system(s). If problems are encountered in performing
these procedures, the installer may refer to aircraft wiring diagrams for harness troubleshooting or
the aircraft maintenance manual to isolate faulty equipment. All discrepancies should be resolved
before proceeding. This section will also load the Regional Terrain Database in MK XXII EGPWS
that will be operating outside of the North American region.
4.2 Harness Checkout and Power Check
Prior to installing any equipment, it is important to verify that all interfaces have been made and
that power and ground at each unit connector is correct, using the wiring diagrams for the
installation. Any discrepancies in the wiring must be resolved before proceeding.
The wire harness should also be checked for proper clearance near any control cables and other
potential areas that may cause binding and/or chafing.
4.3 Unit Installation
After the harness check has been completed and any discrepancies have been resolved, the
units should be installed into their respective racks, and all connections to the wiring harness
should be made (connectors attached). Verify that all of the units are secure in their respective
racks, panels, etc., and all harness connections are secure. Refer to aircraft installation drawings
for the unit locations and mounting information.
4.4 EGPWC Initialization a nd Configuration
The first time a MK XXII EGPWS is turned on in a new installation, the Configuration Module in
the EGPWS harness must be programmed to the specific interface configuration for the aircraft.
This programming is done via RS-232 cable connection between the EGPWC and a PC running
the Honeywell WinViews software. This interface capability is provided to facilitate diagnostic and
configuration functions with the EGPWC during post installation checkout. Refer to Appendix C
for instructions related to using the WinViews software.
4.4.1 RS-232 Communication with the MK XXII EGPWS
The MK XXII EGPWS computer contains software that allows monitoring of its internal
