  • Page 6: General

    1 General 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.

    GPS frequency. Refer to the MX CDU Operator Manual for more details. Turning this feature ON in the MX CDU will initiate the MX525A to track any SBAS satellites that are in view. Please be aware that the SBAS system is not an IMO approved differential correction system.

  • Page 9: Receiver Autonomous Integrity Monitoring (Raim)

    Receiver Autonomous Integrity Monitoring (RAIM) RAIM is a special software algorithm in the MX525A program which provides another layer of safety because it gives the operator an alarm indication if the GPS system accuracy exceeds a predefined tolerance. This feature requires at least five or more GPS satellites to operate properly.

  • Page 10: Installation

    Locate the MX525A within 3 meters from the MX CDU junction box. Should there be a need to install the MX525A much farther away from the MX420 CDU, a longer cable assembly can be specially ordered from Simrad.

  • Page 12: Mgl-4 Antenna Mounting Guidelines

    If you are not sure if the chosen antenna location is appropriate, you can mount the MGL-4 antenna temporarily and connect the coax cable to the MX525A. Using the MX CDU, Monitor the GPS signals under the “GPS Status” screen while you move the MGL-4 antenna around.

  • Page 13: Antenna Mounting

    Antenna Mounting Bracket Mount The MGL-4 antenna mounting thread is an industry standard fitting for VHF antenna mounting (1.0 inch, 14 TPI). This enables the antenna to be mounted on a wide range of mounting brackets, including the swivel joints, commonly used for angled surface.

    300 mA at 12 VDC. An in-line fuse or circuit breaker rated at 2 amp. is recommended for overload protection. When the MX525A is connected to an MX CDU, the 12 VDC antenna power is supplied by the CDU unit.

  • Page 15: Power/Data Cable Assembly

    The red wire connects to the (+) DC power, while the black wire is the negative return. Although the MX525A has a reverse polarity protection, it is prudent to make sure that proper polarity is observed before making the connection.
