SECTION TWO - Installing the unitPage 8 951/952 INSTALLATION MANUAL Revision BUsing DGPS with anAN150 and 8410ACUIf the unit is equipped with a differential receiver (and you’re using theAN150 GPS antenna, not the AN205-P GPS/DGPS combo antenna), thisreceiver must be connected to a Northstar 8410 differential AntennaCoupling Unit (ACU). The ACU’s four-foot whip antenna should bemounted as high as conveniently possible—but not at the highestpoint—and as far away as possible from other antennas. The ACU can bemounted on a standard marine antenna mount (1" diameter, 14 threadsper inch).For complete details on the AN150/8410 ACU mounting requirements,see ”Installing an 8410 ACU (for use with the AN150 only)” starting onpage 23.Using the AN205-PDGPS antennaFor details on the DGPS antenna’s mounting requirements, see ”Choosingan antenna location” starting on page 15.Choosing a system locationThe 951/952 unit houses the GPS receiver, optional differential receiver,computer, power supply, lights, controls and the specially-coated displayscreen. The mounting location should be chosen carefully before anydrilling or cutting takes place: Choose a mounting location that allowsgood visibility of the unit’s screen, is within comfortable reach, and pro-vides a reasonably direct path for running the required electrical cabling.Be sure you have easy access to the control panel’s keys and that the dis-play can be clearly seen from the normal vantage point when the user isnavigating. Even though the display screen contains an effectiveanti-reflective coating, choose a location that will minimize glare fromwindows or other bright objects. Although the 952 is direct-sunlightviewable, for optimal viewing it is recommended that you install the 952in a location that’s out of direct sunlight.Although the unit itself is waterproof, the connectors at the back of theunit aren’t immune to corrosion from saltwater spray. Protect the unitfrom prolonged exposure to the elements by mounting it in a relativelydry area, if possible. At the end of the day, the unit can be wiped off witha damp cloth. When not in use, the unit should be covered with the sun-shield to protect it from excessive heat.To help plan the installation, see Figure 1: ”951/952 dimensions (side),”below and Figure 2: ”951/952 dimensions (front),” below.
