Apm; External Modem And If Switch (Optional); Jetwave Mcs-8562 Terminal Modes Of Operation; Power On Mode - Honeywell JetWave MCS-8562 Installation And Maintenance Manual

SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
• The AISD interfaces provide services to the aircraft/cockpit, such as the electronic flight
bag, data load, etc. This system uses Ethernet (10/100/1000 Base T) interfaces.
• The discrete I/O for aircraft status and for reporting system status.
- Has two LEDs to provide power and fault status on the LRU front panel.
- Accepts 115 VAC from the aircraft.
- Manages the BIT for the complete AES.
- Contains the modem, which transmits and receives to/from the BUC-HPA.
- Controls the BUC-HPA and KANDU (and through it, the OAE) through the Ethernet interface
and RS-422 discretes.
- Controls the IF Switch through discretes.
E.

APM

- The APM holds the configuration data for the system.
- Is powered by the Modman.
F.

External Modem and IF switch (Optional)

- Transmits and receives to/from the BUC-HPA
- Switch Modem signal to/from BUC-HPA.
3. JetWave MCS-8562 Terminal Modes of Operation
The JetWave™ MCS-8562 Terminal 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:
B.

System Initialization Mode

In the System Initialization Mode, the Modman starts additional POST and BITE, system access,
and SNMP services. The Modman attempts to establish communication with KANDU and OAE.
The RF transmission is disabled in this mode.
