Product Specification
HIF-2121/R5 CAGE CODE: 97896 SCALE: NONE SIZE: A DWG NO: 965-1176-601 REV: D SHEET 131
If an error occurs during data loading (i.e. there is a failed load), the EGPWC will NOT attempt to start the application
software but will wait for a new dataload to commence and successfully complete.
Once the dataload is complete, the load request is cleared. If GSE is not present then the EGPWS will be rebooted. If GSE is
present then the EGPWS will run the software previously present in RAM, without resetting the EGPWS or rebooting.
6.10.10.3 PCMCIA Data loading LED’s
Adjacent to the PCMCIA slot on the smart cable there are four LED’s which will be used for data loading activities. These
lights are as defined in section 6.10.5.
The data loader LED’s will be active only when a PCMCIA card is being used to load data. When active, the data loader
LED’s will mimic the performance of the lights on a portable data loader per the ARINC 615 standard.
6.10.11 Configuration Management and Version Identification
The purpose of version identification is to allow the factory and the customers to achieve configuration management as
required by FAA regulations. The purpose of configuration management is to make sure that each installation
contains/consists of all the pieces that it is supposed to contain: hardware, software, and database files.
The primary goal is to quickly, and easily determine the current configuration of a given EGPWC. A lesser goal is for the
EGPWC to do the best job it can in protecting itself from incorrect configuration changes. Other goals include being able to
determine current configuration without having to go into the electronics bay, and to be able to update a software
configuration without removing the box from service.
There are two levels of version identification or configuration on the EGPWC. The first level of identification shows the
configuration that has affect on the form, fit, or function of the EGPWC as seen by the pilot. This identification is
accomplished via the EGPWC part number. The second level of identification provides information on terrain and Envelope
Modulation database versions. Different terrain and Envelope Modulation database versions do not affect the form, fit, or
function of the EGPWC as seen by the pilot.
In order to minimize complexity, the EGPWC utilizes a 10 digit part number. This 10-digit part number identifies the
configuration of the EGPWC, which affects form, fit, or function as seen by the pilot.
The EGPWC is comprised of the following items or subcomponents:
• Hardware (including boot code)
• Application Software (including configuration software)
• Terrain Database
• Envelope Modulation Database
6.10.11.1 10 Digit Part Number Overview
In order to support manufacturing the EGPWC uses a 10 digit part number for production purposes via a 965-XXXX
drawing. The 10-digit part number is defined in section 1.0 of this document.
6.10.11.1.1 Hardware
The hardware contains the following subcomponents:
• Boot code
• Controller Circuit Card Assembly
Main Processor
Analog Interface Processor
Image Generator DSP
• Power Supply Circuit Card Assembly
• Backplane Circuit Card Assembly
Each of the Circuit Card Assemblies (CCA) listed above have a “identification bit” scheme which software can utilize to
report hardware identification.
