Page 4 957 Installation Manual, Revision C1 SECTION TWO: Installing and wiring the 957 Safety considerations WARNING! Before starting the installation, be sure to turn power off. Further, Northstar highly recommends keeping power off while you're installing the system. If power is left on or turned on during the installation, fire, electrical shock, or other serious injury may occur. Be sure that the voltage of the power supply is compatible with the 957's voltage rating--10 to 36 volts DC. Connecting to the wrong power supply can cause fire or damage to the equipment. Be sure to ground the equipment to prevent electrical shock and mutual interference. Be sure to use the proper fuse. Using the wrong fuse can cause fire or damage to the 957. 957 Installation Manual, Revision C1 Page 5 SECTION TWO: Installing and wiring the 957 CAUTION! Make sure that the 957 doesn't interfere with any other on-board systems. Check all other systems to ensure that their performance doesn't degrade when the 957 is turned on. CAUTION! Proper installation of the Northstar 957 is critical to accurately receive and effectively use GPS/WAAS signals under a wide variety of weather conditions. Bench-testing the 957 Northstar recommends bench-testing the 957 before installing it onto the vessel. Bench testing ensures that the equipment is fully operational, and lets the 2201 antenna or 2701 beacon receiver collect the current almanac and ephemeris data for the installed location, which results in less on-board installation time. Mounting the 957 Choosing the best location Choose the mounting location carefully--before you drill or cut. The display screen is high-contrast and anti-reflective, and is viewable in direct sunlight, but for best results, install the 957 out of direct sunlight. See the figure below for additional mounting recommendations. Page 6 957 Installation Manual, Revision C1 SECTION TWO: Installing and wiring the 957 Regardless of the type of mounting, the 957 should be installed in an accessible location (dry) where the operator can easily use the controls and clearly see the display screen. Be sure to leave a direct path for all of the cables. Regardless of the type of mounting, the location should have minimal glare from windows or bright objects. If the 957 is yoke-mounted low, tilt the 957 back for best viewing contrast. Figure 1: Mounting recommendations 957 Installation Manual, Revision C1 Page 7 SECTION TWO: Installing and wiring the 957 CAUTION! Keep the following safe compass distance from the 957: 1.0m standard, 0.8m steering. Flush-mounting the 957 When flush mounting, leave at least two and a half inches of clearance space behind the mounting panel for all of the cables and connectors. Flush mounting requires good ventilation behind the mounting panel. Poor ventilation will cause the 957 to overheat, which, in turn, may cause the display screen to darken. Figure 4 below shows the overall width and height requirements for flush-mounting the 957. For further details, see the full-size Northstar 957 Flush-Mounting Template (part number GT957). This template should be used to drill the mounting holes and cut the mounting panel in the exact recommended locations. CAUTION! When flush mounting, be sure to mount the 957 on a flat surface. Mounting on a curved surface can break or distort the plastic and break the waterproof seal. Do not overtighten the mounting screws; you may damage the case and compromise its waterproof seal. This type of physical damage will void the warranty.

DC power is required from a 10-volt minimum to a 36-volt maximum using at least 16-gauge connecting wire. CAUTION! As a good safety practice, Northstar strongly recommends that you connect the 957 to a circuit breaker or 20-amp fuse at the power source (battery). Connecting the 957 to ship's power A 10-foot power cable is shipped with the 957 system. You can lengthen this cable to a maximum of 25 feet: · · for a cable length up to 15 feet, the power connections must use 16-gauge connecting wire or heavier for a cable length from 15 to 25 feet, use 14-gauge connecting wire or heavier If you lengthen the power cable, use an external fuse at the battery end as an added safety precaution. The fuse size should match the size of the wiring on the vessel. See the NMEA or the American Boating and Yachting Counsel specifications to find the correct fuse to use with your cable. For the best protection from noise, connect the power cable directly to the battery or dedicated electronics buss. The green ground wire should be connected to ship's ground directly. 957 Installation Manual, Revision C1 Page 15 SECTION TWO: Installing and wiring the 957 The power cable has an inline fuse to protect the vessel's wiring, prevent electrical fires, and prevent damage to the 957. If you shorten this cable, be sure to keep the inline fuse intact. The wires in the power cable must be connected as follows. · · · red positive(+) black negative(­) green ship's ground NOTE: Ground the 957 to the vessel to eliminate interference. Without an earth grounding, performance may be reduced. Secure the green wire to the vessel's nearest grounding point. If a noise-free earth grounding point isn't available, cap and insulate the green wire--it shouldn't be used when an earth ground isn't available, or with systems using "floating" grounds. Page 16 957 Installation Manual, Revision C1 SECTION THREE: Installing and wiring the 2201 Introducing the 2201 The Northstar 2201 GPS pod is a self-contained, high performance GPS antenna/receiver that also receives Wide Area Augmentation System (WAAS) differential correction signals. When connected to the 957, the 2201 provides the 957 with WAAS-enhanced GPS position information. For the 2201's technical specifications, see Table 15, "2201 technical specifications," on page 64. CAUTION! Do not open the 2201: There aren't any serviceable parts inside. Unauthorized tampering will automatically void the warranty. 957 Installation Manual, Revision C1 Page 17 SECTION THREE: Installing and wiring the 2201 Installing the 2201 NOTE: Before permanently installing the 2201, try temporarily installing it and using the 957 to see if the 2201's location works well. 2201 parts list The 2201 includes the following parts (see Figure 7: "2201 antenna components," below): · · · 2201 GPS/WAAS pod 3 mounting screws (10-32 UNF) and 3 washers for deck mounting 50-foot 2201 cable (both ends have waterproof 7-pin connectors) 2201 GPS/WAAS pod 50-foot 957POD-CA cable (with two finished connectors) 3 mounting screws and 3 washers Figure 7: 2201 antenna components Choosing the best mounting location Before you drill or cut, choose a mounting location that meets the following criteria. The 2201 should be mounted: · · where there's enough mounting clearance to easily connect the cable. low on the vessel, since side-to-side motion caused by the vessel's rolling can degrade speed-over-ground (SOG) and course-over-ground (COG) readings. Page 18 957 Installation Manual, Revision C1 SECTION THREE: Installing and wiring the 2201 · below the radiation plane of any INMARSAT or radar antennas, and away from any other high-power transmitting antennas (see Figure 8 on page 19). high enough to provide an unblocked view of the sky in all directions, and that minimizes or eliminates any objects that block the 2201's view of the sky (the 2201 uses satellites down to zero degrees elevation or to the horizon). away from masts or objects that could "shadow" the 2201, but where there's an adequate view of the sky. · · To avoid mutual interference among different antennas on the vessel, see the recommendations in Figure 8 below. This figure shows the minimum distances that should separate GPS/WAAS antennas from other antennas and physical mounting surfaces. Normally, these guidelines produce a relatively trouble-free installation. However, you may want to adjust these distances to the particular equipment, since every installation is unique. Figure 8: Recommended separation distances between antennas Mounting the 2201 You can mount the 2201 in one of two ways: · · onto a standard antenna mast onto a flat surface 957 Installation Manual, Revision C1 Page 19 SECTION THREE: Installing and wiring the 2201 Using a standard antenna mast An optional magnetic mount adapter (Northstar part number AM110) is available for certain installations. To order, call the Northstar Sales Department. Using the 1"x 14 marine-industry standard UNS thread mounting, install the base of the 2201 onto a standard antenna mast. Do not overtighten or you may damage the housing! To avoid stressing the 2201's connector with the weight of the cable, use a tie-wrap or similar near the 2201 to hold the cable's weight. 4.50" (114mm) Figure 9: Mounting position for a standard mast mount Using a flat surface You can mount the 2201 onto a deck or any other flat surface: Using the three screws and washers provided, mount the 2201 onto the flat surface using three holes on a 1.75-inch diameter circle (see Figure 10 below). 3.79" (96mm) Page 20 957 Installation Manual, Revision C1 SECTION THREE: Installing and wiring the 2201 1.750 1.00 -14UNS-2Bx 1.00 deep. 3x 3/16" - 32UNF - 2B x .48 deep.

Wiring the 2201 Connecting the 2201 to the 957 NOTE: You can shorten the 957POD-CA cable, but do not lengthen it. The cable must be a maximum of 50 feet. The 50-foot 957POD-CA cable connects the 957 with the 2201. Both ends of the cable are finished with 7-pin connectors that plug into the 2201 and 957: 1. Plug the 2201 end of the cable into the 2201, and the 957 end into the 957 connector labelled "GPS." Note: The cable's connectors may look the same, but they are not interchangeable. 957 Installation Manual, Revision C1 Page 21 SECTION THREE: Installing and wiring the 2201 2. Coil any extra 2201-CA cable away from the 2201. Don't pinch the cable or make any sharp bends, and don't run the cable where it interferes with any controls. Re-fabricating the 957 connector (optional) If you want to shorten the cable or remove its connector to make more room to snake the cable, you can remove the connector from the 957 end and then replace it: 1. After shortening or snaking the cable, slide the available heat shrink tubing onto the cable, then slide the connector backshell onto the cable, as shown below. 2. Prepare each wire for insertion into its solder cup by stripping it and tinning it. 3. Carefully solder each wire to the appropriate cup, as described in Table 2 below. 4. Slide the backshell down the cable and screw it onto the connector body. It should be hand tight. 5. Using the supplied screws, screw the strain relief onto the backshell. 6. Slide the heat shrink tubing onto the connector. Be sure to leave room for the locking collar to retract. 7. Heat the shrink tubing until it shrinks around the connector, providing a watertight seal. For the pin numbers and functions for the 957 end of the cable, see Table 2 below.

The 2701 receives differential corrections from ground-based radiobeacons as well as from satellites transmitting WAAS differential signals. For the 2701's technical specifications, see Table 16, "2701 technical specifications," on page 65. CAUTION! Do not open the 2701: There aren't any serviceable parts inside. Unauthorized tampering will automatically void the warranty. 957 Installation Manual, Revision C1 Page 25 SECTION FOUR: Installing and wiring the 2701 Installing the 2701 2701 parts list The 2701 includes the following parts: · · · · 2701 DGPS/WAAS receiver 10-foot data/power cable for connecting the 2701 to the 957 (both cable ends are finished) AN205-P GPS/DGPS combination antenna 50-foot antenna cable for connecting the 2701 to the AN205-P (both cable ends are finished) Choosing the 2701 mounting location The 2701 is housed in a rugged aluminum enclosure with a mounting flange, gaskets, and watertight connectors. Though designed to withstand the marine environment, the unit is not completely waterproof. Protect the 2701 by installing it where water won't contact it directly or enter it by following data/ power or antenna cables. Mounting the 2701 You can mount the 2701 either horizontally or vertically using the appropriate mounting holes--see Figure 11 on the next page. Keyhole slots at the rear will help if you're installing the 2701 where access is limited and it's hard to start the mounting screws at the obstructed end. Securely tighten all mounting screws to avoid vibration-related problems. Page 26 957 Installation Manual, Revision C1 SECTION FOUR: Installing and wiring the 2701 Figure 11: 2701 case and mounting dimensions Wiring the 2701 Connecting the 2701 to the 957 The 10-foot 957BDM-CA cable connects the 957 with the 2701. Both ends of the cable are finished with connectors that plug into the 2701 and 957. Plug the cable's 25-pin connector into the 2701, and the 7-pin connector into the 957 connector labelled "GPS." In case you have to remove one of the cable's connectors, be sure to re-fabricate the cable using the wiring connections described in the table below.

A small, but significant, number of 2701's are damaged due to incorrectly wired connections. Such damage is not covered under warranty. Be sure you aren't applying primary voltage directly to any of the 2701's signal input/output wires. This may vaporize the internal circuit board conductors. Installing the AN205-P antenna Choosing the antenna's mounting location The 2701 operates with Northstar's AN205-P "combo" GPS/ DGPS antenna. Mount the antenna high enough to clear any objects and get an unobstructed view of the horizon in all directions. Mount it low enough on the vessel to avoid extra motion from pitching and rolling, and lower than any high-power transmitting antennas, such as radar or satcom (see Figure 8 on page 19 for recommended separation distances between antennas). Keep the antenna at least six feet away from objects that can "shade" GPS or differential signals. NOTE: Before permanently installing the AN205-P, try temporarily installing it and using the 957 to see if the antenna location works well. Page 28 957 Installation Manual, Revision C1 SECTION FOUR: Installing and wiring the 2701 CAUTION! Don't mount the antenna near rotating warning beacons or strobe lights, electric motors, fluorescent lights, or other RF sources. These can create RF interference to the differential reception. If position data is intermittent, make sure you have the proper cable length, and verify the quality of the antenna location and the quality and proper termination of the connectors. Also, make sure that the 2701's ground lug terminal is securely connected with a heavy gauge conductor to ship's ground. 7.00 2.5 Use the locking nut shown to prevent rotation of the antenna or bottoming out of the mounting stanchion into the threaded mount portion of the antenna. If done with enough force, either of these may break the antenna. TNC 3.5 Figure 12: Northstar AN205-P antenna dimensions Connecting the 2701 to the antenna The 50-foot antenna cable connects the 2701 with the AN205-P antenna. The cable length must be a maximum of 50 feet but can be shortened to the desired length. Note: Installations that require a cable length from 50 to 100 feet should order the AN206 combo antenna and a 100-foot length of coaxial cable from the Northstar Sales Department. Don't make any tight bends in the cable, and fasten it along its length to avoid chafing or whipping or any kind. Coil up any unused length of cable. Be sure that the cable connectors are securely fastened. 957 Installation Manual, Revision C1 Page 29 SECTION FOUR: Installing and wiring the 2701 Page 30 957 Installation Manual, Revision C1 SECTION FIVE: Checking out the system Inserting a chart cartridge The cartridge slot is located at the lower left-hand corner of the 957. Before inserting a Navionics chart cartridge, make sure its label is facing up and that the cartridge is oriented as shown in Figure 13 below. Insert the cartridge gently but firmly into position with one straight, smooth motion. If you only partially insert the cartridge, stop, then move the cartridge again, it may get stuck in an awkward position. 957 INSTALLATION MANUAL, Revision C1 Page 31 SECTION FIVE: Checking out the system The Navionics chart cartridge must stay free from debris and moisture at all times. To ensure that you don't expose the cartridge to any environmental damage, please use caution when changing the cartridge. Be careful when inserting the cartridge into the 957 (see description above and illustration at right). When you're not using the cartridge, store it in a clean, dry place away from heat, humidity, and dust. Improper handling and storage of the cartridge may damage the 957. Such damage isn't covered under the 957 warranty. Figure 13: Properly inserting a chart cartridge Page 32 957 INSTALLATION MANUAL, Revision C1 SECTION FIVE: Checking out the system Turning the 957 on and off To turn on the 957, briefly press the PWR key. The 957 emits several short beeps as it displays the START-UP screen, then the 957 performs a series of self-tests to check its critical components and functions.

To continue, accept the warning message by pressing any one of the five function keys (CHART, STAR, STEER, NAV LOG, or WAYPTS/ROUTES) located below the display screen. NOTE: A brief warm-up period may be required for the display screen to reach its full intensity. To identify the cartridge inside the 957, press the CHART SETUP menu key to the right of the CHART screen to display the CHART STATUS screen (the cartridge door must be fully closed and latched to display this information): 957 INSTALLATION MANUAL, Revision C1 Page 33 SECTION FIVE: Checking out the system · if a cartridge is inside, the cartridge name and date are shown on the left of the CHART SETUP/STATUS screen (screen at left, below). if a cartridge isn't installed or is installed incorrectly, the words NONE INSERTED are shown (screen at right, below). · NONE INSERTED The cartridge name comes from its Navionics catalog number. Not all cartridges will have a date, especially older ones; in this case, only the word PRESENT is shown rather than the name and date. Checking satellite status The 957 uses a high-performance GPS receiver as its primary source of position data, augmented by either the WAAS satellite system, or the radiobeacon differential (DGPS) system if the 957 is connected to the optional Northstar 2701 receiver. To see if the 957 is using WAAS or DGPS, press the CHART key to display the GPS POSITION screen and look for the WAAS or DGPS indicator below and to the right of the lat/lon display. . Page 34 957 INSTALLATION MANUAL, Revision C1 SECTION FIVE: Checking out the system To see more information about DGPS, on the GPS POSITION screen, press the DGPS INFO key to display the DGPS STATUS screen. Check for low noise levels and mid-range SNR readings. To display more information about signals received from the satellites, press the SAT INFO menu key. GPS satellite number 36 WAAS satellite number Figure 14: Satellites on the GPS satellites screen The satellite map on the GPS SATELLITES screen shows the current location of the satellites in the sky. The 957 displays GPS satellites as circles; WAAS satellites as hexagons. You can check the quality of their signals by looking at each satellite's Signal-to-Noise Ratio (SNR). The higher the ratio, the better the quality. While the U.S. government identifies WAAS satellites by their pseudo random number (PRN)--a three-digit number ranging from 120 to 138--the 957 identifies them by two-digit numbers ranging from 33 to 51. For example, the satellite for the Atlantic Operating Region (AOR) is PRN 122, which the 957 displays as 35. See Table 4 below for the satellite identification numbers that may be displayed on the 957's screen. Table 4: Satellite identification numbers PRN ON GPS SATS SCREEN PRN ON GPS SATS SCREEN 120 33 121 34 122 35 123 36 124 37 125 38 126 39 127 40 128 41 129 42 130 43 131 44 132 45 133 46 134 47 135 48 136 49 137 50 138 51 957 INSTALLATION MANUAL, Revision C1 Page 35 SECTION FIVE: Checking out the system Selecting differential options The 957 has several settings for differential reception. To select one, press the STAR key to display the OPTIONS/SERVICE INFO screen, then press the RECEIVER OPTIONS key to display the RECEIVER OPTIONS screen. The DIFFERENTIAL OPERATIONS field offers the following options (depending on the equipment that's connected to the 957): · · DISABLED - to turn off all differential corrections RADIO BEACON - to force radiobeacon differential if the 957 is connected to a radiobeacon source (for example, the optional 2701) WAAS - to force WAAS differential corrections if the 957 is connected to a WAAS-capable unit (for example, the 2201 or optional 2701) AUTO - (the default setting) to prefer WAAS differential corrections, but if the 957 is connected to the optional 2701, the 957 will automatically switch to radiobeacon corrections if and when WAAS becomes unavailable or is less accurate than radiobeacon · · About auto-dimming mode When the display screen is at full brightness, if the 957 gets too hot inside due to the outside temperature and sunlight, the display screen will automatically dim. Auto-dimming helps maintain the integrity of the display and reduce power consumption when the 957 is on and running too hot for its current environment. You can override the auto-dim function at any time by increasing the brightness with the BRIGHTNESS key. The 957 may dim again as required so as not to exceed the maximum internal temperature. Using the remote control If you point the remote directly at the 957 and are within nine feet, you can operate all of the 957's keys except the PWR key. To turn off the 957, press and hold the PWR key for a few seconds until the screen goes dark.
