  • Page 11: Mx575 Mounting

    MX575A/B DGPS Compass 2. MX575 Mounting The preferred orientation for the MX575 D/GPS Satellite Compass is parallel to the axis of the vessel. In other words, it should be pointing towards the bow of the boat. This mounting configuration will provide the ability for the MX575 to output the positioning, heading and pitch of the vessel.

  • Page 12: Mx575 Mounting Guidelines

    MX575A/B DGPS Compass should be programmed into the MX575 to calibrate its heading. Obviously, the physical orientation of the MX575 could be adjusted to correct for this deviation. MX575 Mounting Guidelines Install the MX575 where it has a clear view of the sky around it.

  • Page 13: Installation Procedure

    MX575A/B DGPS Compass 2.2 Installation Procedure 2.2.1 Mounting The MX575 may be mounted with either the fixed-base or pole-mounting base. Both mounts are supplied with the system. The fixed base allows you to mount the MX575 on horizontal flat surfaces, such as radar platforms.

  • Page 14: Fixed Base Mounting

    MX575A/B DGPS Compass The following figure shows the MX575 with the pole mount Figure 4 - MX575 with Pole-Mount base 2.2.2 Fixed Base Mounting The supplied fixed base is intended to allow you to mount the system on a flat surface.

  • Page 15: Figure 6 - Bottom View Of Fixed-Mount Base

    MX575A/B DGPS Compass The base also features four tunnels that allow you to bring the power/data cable out from within the mount in order to route it along the surface of the plate beneath the MX575 system. Alternatively, you may wish to route the power/data cable through the mounting surface rather than bringing it out through one of the tunnels.

  • Page 16: Figure 7- Running Cable Through The Fixed Base Mount

    MX575A/B DGPS Compass To install the MX575 using the fixed base, insert either end of the power/data cable through the center of the fixed base as shown in the following two figures. Figure 7- Running cable through the fixed base mount...

  • Page 17: Figure 9- Power/Data Cable Key And Keyway

    MX575A/B DGPS Compass Align the connector keyway of the cable to the key of the connector mounted on the MX575 enclosure as show in Figure 8. Insert the cable-mount connector into the bulkhead connector, aligning the locking ring at the same time.

  • Page 18: Figure 11- Fastening The Fixed-Base To The Mx575

    MX575A/B DGPS Compass Once you have secured the connector, slide the fixed base up to the bottom of the MX575 enclosure. There are two alignment keys on top of the base that must fit into two holes of the enclosure.

    MX575A/B DGPS Compass Thread the pole mount base onto the pole mount four to five full turns. Figure 18 - Threading the Pole-Base onto the mount Ensure that there’s a gap between the lock nut and washer, and the pole mount base as shown in the following figure.

  • Page 24: Figure 20 - Power / Data Cable Key And Keyway

    MX575A/B DGPS Compass At this point, fasten the cable to the MX575 connector. Notice that the connector on the receiver enclosure has a key and that the cable-mount connector has a keyway. The key and keyway need to align as you insert the cable-mount connector into the bulkhead connector.

  • Page 25: Figure 21 - Connected Power / Data Cable

    MX575A/B DGPS Compass Figure 21 - Connected Power / Data cable The next step is to fasten the MX575 enclosure to the pole mount base using the supplied self-tapping screws. The following figure illustrates this process. There are two alignment keys on top of the base that must fit into two holes of the MX575 enclosure.

  • Page 26: Figure 22 - Fastening The Pole Base To The Mx575

    MX575A/B DGPS Compass Figure 22 - Fastening the Pole Base to the MX575 The next step is to rotate the hex nut and washer up to the bottom surface of the pole mount base. Do not tighten them at this point as you will need to align the MX575.

  • Page 27: Figure 24- Locking The Mx575 Once Aligned

    MX575A/B DGPS Compass Orient the MX575 using the gun-sights on the top of the enclosure.

    MX575A/B DGPS Compass If you have another accurate source of heading data on your vessel, such as a gyro compass, you may use its data to correct for a bias in MX575 alignment using the MX CDU configuration. Alternatively, you may wish to physically adjust the heading of the MX575 so that it renders the correct heading measurement, however, adding a software offset (see pgs.

  • Page 30: Mx575 Operation

    MX575A/B DGPS Compass 3. MX575 Operation The MX575 D/GPS Satellite Compass is powered by connecting the Red (18 gauges) and Black (18 gauges) to an 8 to 36 VDC power source. Once powered, the MX575 will proceed through an internal start-up sequence, however it will be ready to communicate within a few seconds.
