2.3 Honeywell Implementation
The Honeywell implementation varies from the ARINC 791 configuration as follows:
• No ARINC 629 support is provided (optional in ARINC 791).
• No EN1 Ethernet functionality between the KRFU and KANDU is provided (the provisioned
standard inter-wiring is not utilized).
• ARINC 791 TX Mute between the Modman and the KANDU is optional, the Honeywell
implementation uses RS422 signaling on manufacturer-specific circuits 3 to 4 instead.
• Manufacturer-specific circuits 1 to 6 carry a BUC Mute signal, a Filter Select signal, and a
KANDU Reset signal.
• The RSSI function is in the Modman.
• No EN2 Ethernet interface functionality between the KANDU and OAE on the TMA variant (the
provisioned standard inter-wiring is not utilized).
• The A350 variant of the ARINC 791 style configuration, has AIM kit fittings that deviate from the
ARINC 791 coordinate listing for the 7 fitting.
• There are LED indicators on the front panel of the Modman to show status.
Refer to SECTION 3 SYSTEM PRE-CONFIGURATION, AES Configuration Data for the details of ARINC
429 labels required for the JetWave™ System.
2.4 JetWave™ System Modes of Operation
The JetWave™ system supports the following modes of operation:
• Power On
• System Initialization
• Normal Operation
• Critical Fault
• Data-Load
• Commanded.
A. Power On Mode
Each LRU enters Power On Mode when power is applied. RF transmission is disabled in this mode.
In this mode, the Modman does POST and other invasive tests. If no failures are detected, the
system enters into the system initialization mode.
NOTE:
SNMP and continuous BITE are not available at all times during this mode.
