SYSTEM DESCRIPTION AND INSTALLATION MANUAL
JetWave™ System
© Honeywell International Inc. Do not copy without express permission of Honeywell.
(a) The JetWave™ AES consists of the Modman, KANDU, KRFU, TMA or FMA LRUs, plus
the APM.
(b) The APM is a simple memory device with no software and performs no BITE by itself.
Any BITE required for the APM is performed by the Modman. The APM is not shown in
these diagrams.
(c) The BITE system divides the responsibility for BITE and historical logs in a BITE
hierarchy as illustrated in Figure 3-22.
Figure 3-22. Bite Hierarchy
(d) In charge of JetWave™ system is the AES controller. This controller is in charge of the
LRUs of the JetWave™ system, and it:
• Maintains the overall state of the AES system
• Controls the initialization and operation of the system
• Generates BITE events applicable to the system level
• Records BITE events reported by a LRU and itself in an AES historical log.
(e) Each LRU has a LRU controller that:
• Maintains the state of the LRU
• Generates BITE events applicable to the LRU
• Sends relevant BITE events to the AES controller (for the AES controller to make a
decision on overall AES state, and for it to record in its AES historical log).
(f) The diagram that follows is a detailed description of how the AES controller, the LRU
controllers, the historical logs, and the means of access to those logs interact. Refer to
Figure 3-23.
