This manual describes the operation and installation of
the MX525A DGPS sensor (with the MGL-4 antenna) and
older version MX525 black box DGPS sensor (with the
MGL-3 antenna). Their wiring hook-up is identical and
the antennas are interchangeable.
The MX525A is a blackbox GPS and Differential Beacon
receiver combination. It has a 10-pin connector for power
and data connection and a TNC connector to connect to
an active GPS and Beacon combo antenna.
When connected to an MX-CDU (MX420 or MX5xx), the
MX525A can be controlled to function in several modes,
namely;
GPS only •
DGPS mode in Auto/Database search or Manual •
WAAS (Wide Area Augmentation System-US system) •
EGNOS (European Geostationary Overlay System) •
RAIM (Receiver Autonomous Integrity Monitoring) •
This sensor was designed to use as:
Source of DGPS positioning for any MX CDU model •
Retrofit for IMO compliant GPS and AIS installation •
D/GPS positioning for ECDIS and other charting •
software
The MX525A can achieve better than 2-meter accuracy
in areas with good beacon differential coverage and
autonomous GPS accuracy better than 5 meters. The
built-in beacon receiver can be operated to do auto-
global search, database search or manual mode when
connected to the MX CDU.
Before installing the MX525A, please read this manual
carefully to ensure proper installation and operation of the
unit.
