Mx500/Dc (Dual Control); Mx500/Brim (Backup Receiver Integrity Monitoring) - NorthStar MX500 Operator's & Installation Manual

Functional Description

MX500/DC (Dual Control)

This is a dual-control CDU system where one MX500 (operating as
a master) and the other (operating as a slave) are supplied. Only one
smart DGPS antenna is required. The antenna unit is connected
only to the MX500 master unit.
Note: LAN port must be setup before enabling this feature. The
units can be connected together over an Ethernet cross-over cable
or using an Ethernet switch. See page 118 of this manual for in-
structions on how to setup LAN.
MX500 BR Beacon and Remote Configuration

MX500/BRIM (Backup Receiver Integrity Monitoring)

This is an enhanced Dual-Control configuration wherein two MX500
CDUs and two smart DGPS antennas are supplied. The two MX500
units are connected in dual-control configuration but they operate as
independent navigator units with dedicated antennas. The Dual Con-
trol Integrity Monitoring (IM) feature is a software option that works
in the MX500 CDU hardware.
This configuration allows data to be shared between two remotely
separated stations (i.e. navigator's station and helmsman's station),
with independent access to various information fields. The purpose
of this configuration is to enable each CDU to calculate its own posi-
tion, then check the operational status of the other GPS receiver. The
GPS receiver with the best overall operational status then provides
the system position. This provides a fully redundant system, with
self-recovery capabilities.
