APPENDIX 2 SUBSYSTEM
Where the network configuration requires the use of a HUB-3000, the [Subsystem] settings must
also be configured. For example, in a configuration like the one below, if the Subsystem settings
are not configured, No. 1 ECDIS can only receive data from No. 1 Gyro, and No. 2 ECDIS can
only receive data from No. 2 Gyro.
By configuring the Subsystem settings, the HUB-3000 allows the sharing of sensor data between
No. 1 ECDIS and No. 2 ECDIS.
Subsystems A to Z are defined as follows:
• Subsystem A: Configurations which include sensor adapters connected to a HUB-100.
• Subsystem B to Z: Configurations where sensor adapters are directly connected to the PCU.
Examples of Subsystem settings are:
• Subsystem A: No. 2 Chart Radar, No.2 ECDIS, No. 3 ECDIS
• Subsystem B: No. 1 ECDIS
• Subsystem C: No. 1 Chart Radar
