Only mount this unit in a horizontal position with adequate space for ventilation, maintenance and for field service removal. Rough handling during removal or installation can cause premature failure of internal components. · Radar interference - Do not install the processor or its associated cabling in areas exposed to interference from radar, high powered transmitters or large-current-carrying cables. The processor should be mounted as far as possible below the beam of radar antennas. Flybridge installations of the processor are not recommended and should be avoided. Installations in these areas require special provisions for shielding and the installation design must provide total protection from any moisture. Problems caused by moisture, vibration and interference are not covered by warranty. The processor must be mounted in a horizontal position so that its heat management system can work correctly. For advice regarding equipment placement, please consult with an authorized BNT-ME Servicing Dealer before beginning the installation.

B Page 3 SECTION ONE: Introducing the 972 Page 4 972 Installation Manual, Rev. B SECTION TWO: Installing and wiring the 972 SECTION TWO: Installing and wiring the 972 WARNING! Before starting the installation, be sure to turn electrical power off. 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 972's voltage rating of 10 to 32 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 a 7-amp fast-blow fuse in the supplied power cable. Using the wrong fuse can cause fire or damage to the 972. 972 Configuration The Northstar 972 uses a processor module that must be mounted in a protected location and a control head that can be exposed to water splash. A DVI video cable and a control cable feeds communication between the processor and the control head. All interface wiring connects to the processor. Power wiring connects to the processor and control head. Because the control head uses a 15-inch LCD, making the unit large and heavy, it is designed to be flush-mounted, with no provision for yoke-mounting. Bench-testing the 972 Northstar recommends bench-testing the 972 with a GPS antenna before installing it onto the vessel. Bench testing ensures that the equipment is fully operational, and lets the unit collect the current almanac and ephemeris data and a local position fix, which results in less on-board installation time. 972 Installation Manual, Rev. B Page 5 SECTION TWO: Installing and wiring the 972 Mounting the Control Head CAUTION! Proper installation of the Northstar 972 is critical to accurately receive and effectively use GPS/WAAS signals under a wide variety of weather conditions. Keep the following safe compass distance from the 972 head and processor: 1.0m standard, 0.8m steering. Choosing the best mounting location Choose the mounting locations carefully before you drill or cut. The control head should be mounted so that 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. The display screen is high-contrast and anti-reflective, and is viewable in direct sunlight, but for best results, install the 972 out of direct sunlight. The chosen location should have minimal glare from windows or bright objects. Leave sufficient clearance space behind the control head for all of the cables and connectors. Good ventilation is required behind the mounting panel. Poor ventilation may cause the 972 to overheat, which, in turn, will cause the screen brightness to dim. For overall width and height requirements, see the Northstar 972 Mounting Template (P/N GT15), which you can use to drill the mounting holes and cut the mounting panel in the exact recommended locations. CAUTION! Be sure to mount the 972 on a flat surface. Mounting on a curved surface can result in water leaks. 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. Use the supplied template to cut the hole for the control head, and use the supplied gasket between the control head and the instrument panel to help seal against water penetration. The use of anti-seize compound on the flush-mount studs and nuts is recommended. The parts kit contains 12 threaded studs, flat washers, lock washers, and hex nuts for flush mounting.

B SECTION TWO: Installing and wiring the 972 17.5 12.5 15" 5.0 Dimensions in inches Figure 1: Control head dimensions Mounting the Processor The processor should be installed in an accessible, dry location where cabling can be accessed and suitable ventilation is present. See the 972 Processor Mounting Template (P/N GT972) for hole locations and clearance requirements. It is absolutely necessary to mount the processor in a horizontal position as shown in Figure 2 so that the unit's heat management system will work correctly. Normal motion of the vessel will not cause a problem, but vertical or permanently angled mounting of the processor will cause overheating of the unit's microprocessor. A mounting plate is permanently mounted to the vessel, and the processor slides onto the plate and is secured with two screws at the front edge. Vertical clearance of at least 7-1/2 inches is required for installation and removal of the processor. Be sure to provide ample clearance around the processor to make it easy to install and remove cables at the rear of the unit. 972 Installation Manual, Rev.

When wiring the 972, follow the guidelines below. DON'T DO THIS! · Don't make sharp bends in the cables · Don't run cables in a way that allows water to flow down into the connectors · Don't route the data cables in areas adjacent to radar, transmitter, or large-current-carrying cables · Don't attempt to cut or splice the DVI or control cables. If longer versions are necessary, use the optional longer cables. (see Figure 5: "System Wiring," below) DO THIS! · Do make drip and service loops · Do tie-wrap all cables to keep them secure · If cables are shortened, lengthened, or re-terminated, do seal and protect all wiring connections · Do leave room at the back to install and remove cables and keep them separated and organized Page 8 972 Installation Manual, Rev. B Control head connectors Control head connectors are shown in Figure 3 on page 9. The control head connects to: · DC power, through the supplied WA-535 cable with a 7-Amp in-line fuse. · The processor module, using the supplied WC276-9 DVI video cable and the supplied WA612-9 data cable.

Power requirement is 10 VDC minimum to 32 VDC maximum, using at least 16-gauge connecting wire. CAUTION! To protect the power wiring, Northstar strongly recommends that you connect the 972 to a circuit breaker or 7-amp fuse located at the power source (battery or switch panel). Connecting the 972 to ship's power The 972 is shipped with 10-foot power cables for the processor and control head that you can lengthen to a maximum of 25 feet: · for a cable length up to 15 feet, use 16-gauge wire or heavier · for a cable length from 15 to 25 feet, use 14-gauge wire or heavier 972 Installation Manual, Rev. B Page 11 SECTION TWO: Installing and wiring the 972 If you lengthen the power cable, use an external fuse at the battery end as an added safety precaution. The fuse size should be chosen to be appropriate for the size of the smallest conductor in the circuit. See the NMEA or American Boating and Yachting Counsel specifications to find the correct fuse for your wiring. For the best protection from noise, connect the power wiring directly to the battery or dedicated electronics bus. The green wire should be left unconnected. The power cable has an inline fuse to protect the vessel's wiring, and prevent electrical fires and damage to the unit. If you shorten or lengthen this cable, be sure to keep the inline fuse intact (or provide circuit breaker protection). Spare in-line fuses are not supplied with the unit and should be purchased locally to avoid loss of function. Connect the wires in the power cable as follows. · red positive (+) · black negative (­) · green no connection NOTE: The green wire should be left unconnected, and must be capped off and securely insulated.

B SECTION THREE: Installing and wiring the GPS antenna SECTION THREE: Installing and wiring the GPS antenna The 2301 antenna Figure 6: 2301 GPS Antenna NOTE: Do not open the 2301: There aren't any serviceable parts inside. Unauthorized tampering will automatically void the warranty. Mounting and wiring Choosing the best mounting location Before you drill or cut, choose a mounting location that meets the following criteria. The 2301 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. · below the radiation plane of any INMARSAT or radar antennas, and away from any other high-power transmitting antennas (see Figure 7 on page 14). · high enough to provide an unblocked view of the sky in all directions, and that minimizes or eliminates any objects that block the 2301's view of the sky (the 2301 can use satellites nearly as low as the horizon). 972 Installation Manual, Rev. B Page 13 SECTION THREE: Installing and wiring the GPS antenna · away from masts or objects that could "shadow" the 2301, but where there's an adequate view of the sky. NOTE: Before permanently installing the 2301, try temporarily installing it and using the 972 to see if the location works well (see "Checking satellite status" beginning on page 21 to determine whether or not the selected location provides good reception). The 2301 uses a mount with an extension, and the cable is routed through the inside of the extension. To avoid mutual interference among different antennas on the vessel, see the recommendations in Figure 7 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, since every installation is unique, you may want to adjust these distances to the particular equipment. Figure 7: Recommended separation distances between antennas Page 14 972 Installation Manual, Rev. B Mounting and wiring the 2301 The 2301 is mounted onto a standard antenna mount. To complete this installation, you'll also need a standard antenna mount, mounting extension, and mounting adapter. To install the 2301: 7 1.

Screw a mounting adapter onto the extension, bringing cable up through hollow core of the adapter and out the top. 5. Screw the 2301's bottom half (base) onto mounting adapter. 6. Plug the cable's connector into connector on the 2301's Figure 8: Mounting the 2301 on an antenna mount 972 Installation Manual, Rev. B Page 15 SECTION THREE: Installing and wiring the GPS antenna Re-fabricating the 972 connector If you ever want to shorten the antenna cable, or remove its connector to make more room to run the cabling, you can remove the connector from the 972 end and then replace it: 1. After shortening or snaking the cable, slide an appropriate sized piece of heat shrink tubing onto the cable (large enough to fit over the connector backshell). 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 7 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 972 end of the cable, see Table 7 below.

B SECTION FOUR: Networking the Northstar 972 SECTION FOUR: Networking the Northstar 972 NOTE: This entire section can be ignored for a simple installation with no networking involved, or for an installation that involves only traditional NMEA connections. The 972 uses Northstar's networking technology, based on the Ethernet standard and conforming to the IEEE 802.3u 100Base-TX specification (also referred to as "Fast Ethernet.") A single cable with standard connectors simply plugs into each unit. Multiple 972 displays can automatically: · Share chart permits between units. Chart access codes must be entered into the master unit, but networking allows these codes to display charts on all connected units. · Share all waypoints and routes between units. Any changes made to the waypoints and routes in one unit are copied to the other units with no action by the user. Waypoint and route navigation control is available from all networked units. · Share echosounder data from the Northstar 491 between units. The 491 can be controlled from any display unit. · Share radar data from Northstar radar between units. The radar can be controlled from any 972 display. The present software release is limited to supporting two networked units. 972 networking is not compatible with Northstar's N2 networking protocol. NTSC video is not shared over the network because of bandwidth limitations. Separate coaxial video cables must be run to each display unit that will display video. Waypoint and route transfer between a 972 and a Northstar 951, 952, 957, 958 or 6000i is accomplished using the AUX port as described in "Using the Aux Port" starting on page 29. Ethernet cables are not included with the unit, since types and lengths vary by installation. Networking setup In any networked installation, one and only one 972 must be designated as the master unit. All others are designated as slaves. All 972 units are shipped from the factory configured as masters, and any units to be used as slaves must be reconfigured before they are operational. A unit that needs configuration displays a Network Configuration Status screen at start-up. Use the cursor pad to designate a master or a particular slave number, and press Done. The GPS antenna must be connected to the master unit. It is recommended that the optional heading sensor, echo sounder, and other NMEA devices also be connected to the master unit, for two reasons: 972 Installation Manual, Rev. B Page 17 SECTION FOUR: Networking the Northstar 972 · if an NMEA device is connected to a slave unit, that slave must be turned on and operating for that device to be functional across the network · should there be a failure in the master unit, a slave could be temporarily moved to that location, and this is easier to accomplish if all interfaces connect to that same unit However, NMEA devices can be connected to any networked unit, if necessary. Restrictions on networking There are only four restrictions on the use of networking. These restrictions must be observed, or the network will not function. · one and only one master must be a part of any network · the master unit must be turned on at all times when the system is in use · all units on the network must have the same software revision · at present, a maximum of five units may be connected on any network If the master unit becomes unavailable for any reason, the user is prompted with instructions to temporarily designate a slave unit as a master. Technical details The networking port found on the Northstar 972 devices conforms to the electrical specifications set forth by the IEEE 802.3u 100Base-TX standard. This standard is also referred to as "Fast Ethernet." The cabling used is data grade category 5 or 5e Unshielded Twisted Pair (UTP) terminated with RJ-45 connectors on both ends. The standard allows for transmission of raw data at speeds of 10 and 100 Megabits per second depending on the device being communicated with. Although Fast Ethernet is a commonly used standard, particularly in computer Local Area Networks and peripherals, the 972 should only be connected to equipment specified by Northstar to avoid unexpected operation. Installation Planning Ethernet cables should be kept several inches away from power cables and other wiring that might generate interference (such as radar and echosounder cables). When necessary, Ethernet cables should cross these other cables at right angles. Standard off-the-shelf Ethernet cables can be used. These cables are available in a variety of lengths and can be obtained from sources that carry computer networking supplies. The installer should ensure that the cable is category 5 or category 5e cable. Other cables, particularly voice grade cables, look very similar but will not work properly. Page 18 972 Installation Manual, Rev. B Number of devices The initial survey should also determine whether or not an Ethernet switch will be needed. A switch is only necessary if the installation includes more than two devices. For example, networking two 972s and radar requires a switch. Connecting a network of two devices The simplest way to interconnect a network consisting of just two devices is to use an Ethernet "crossover" cable. A crossover cable eliminates the need for an Ethernet switch. Connecting a network of more than two devices When more that two devices are being connected, or if you wish to leave room for future expansion, use an Ethernet switch that serves as a common connection point for all devices. Never use crossover cables with a switch. Ethernet Switches Ethernet switches allow for the interconnection of more than two devices. Each device can exchange data with any other device connected to the switch. Any standard 10/100 Mbit Ethernet switch can be used. These devices generally come with a "Wall Wart" type of a power adapter which is plugged into a 110V AC power outlet. The Northstar 972 has been tested with the following Ethernet switches using standard Category 5 cables: Manufacturer Netgear ADAM Model FS108 6520 Northstar P/N Speed(Mbits) 10/100 Auto Ports 8 5 SW103 972 Installation Manual, Rev. B Page 19 SECTION FOUR: Networking the Northstar 972 Page 20 972 Installation Manual, Rev. B SECTION FIVE: Checking out the system Turning the 972 on and off To turn on the 972, gently and briefly press the PWR key. The unit emits several short beeps as it displays the start-up screen, then performs a series of self-tests to check its critical components and functions. Next, a message is shown reminding against relying on the 972's chart cartography as the only means of safe navigation. To turn the unit off, press and hold the PWR key for several seconds, until it turns off. Important: Wait at least 10 seconds before turning the system back on to allow all voltages to decay. Chart data The 972 is shipped with all chart data preprogrammed in the processor. Charts are unlocked for access as needed (see the Northstar 972 QuickStart Guide and Reference Manual (P/N GM972UM). Checking satellite status To see information about signals from the satellites, press POSITION and then Sat Info. The satellite map on the GPS satellites screen shows the current location of the satellites in the sky. The 972 displays GPS satellites as circles; WAAS satellites as ovals. 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. WAAS satellite number GPS satellite number Figure 9: Satellites on the GPS satellites screen 972 Installation Manual, Rev. B Page 21 SECTION FIVE: Checking out the system Although the U.S. government identifies WAAS satellites by their pseudo random number (PRN)--a three-digit number ranging from 120 to 138--the 972 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 972 displays as 35. See Table 8 below for the identification numbers for WAAS satellites that may be displayed on the screen. Table 8: WAAS satellite identification numbers PRN ON GPS SATS SCREEN 120 33 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 Installation-test checklist To check-out the 972 system after installation: 1. Turn on the 972, then check for the presence of GPS and WAAS. 2. Review the functions. 3. Confirm that the GPS receiver options are at the desired setting. Press the STAR key to display the Options/Service Info screen, then press the Navigation Options menu key to display the Navigation Options screen. If necessary, use the cursor pad to move the arrow in the left column, press EDIT, change to the desired setting, then press ENTER. For more in-depth information about troubleshooting the 972 installation, see "SECTION SEVEN: Troubleshooting and servicing the 972 system" starting on page 35. Checking the network If two 972s are networked together, they should be checked by turning all units on (making sure that one has been designated as the master). Then perform the following test on any unit: 1. Press the STAR key several times to display the Options/Service Info screen. 2. Press the Diagnostics... menu key to display the Diagnostics screen. 3. Press the Network Status... menu key. 4. All units detected by the networking software are listed, with their model number and serial number. 5. Check that all units are present. If any are missing from the list, check their cabling and master slave designation. Check that the switch (if present) has power and that its status lights are flashing for all connected units.

Press Port 1 setup... or Port 2 setup... to display a list of data-format control options, as shown below. Page 24 972 Installation Manual, Rev. B SECTION SIX: Interfacing the 972 system The devices interfacing with the 972 may have special requirements; check their installation instructions. The factory settings are appropriate for most devices, but the following are available for special circumstances. Table 10: Setup options for the NMEA port Setting OUTPUT FORMAT (see below) NMEA 0183 TALKER ID (see page 26) NMEA 0183 LL PRECISION (see page 27) OUTPUT RATE (see page 27) NMEA 0183 WAYPT ID AS (see page 27) NMEA 0183 CHECKSUMS (see page 28) OUTPUT DATUM (see page 28) Choices For either port 1 or port 2, choose NONE or 0183 V2.1 choose GP, LC, or II, to make the 972 look like a GPS receiver, Loran-C receiver, or an "integrated instrument" choose hundredths of minutes, thousandths of minutes, or ten-thousandths of minutes choose 1 to 999 seconds for the interval at which data is sent to the external device choose NAME or NUMBER for the identifier of waypoints sent to the external device choose ON or OFF for compatibility with some older devices choose from a list of datums to apply to your lat/lon coordinates, if necessary (The factory default datum is WGS-84) Choosing the output format The 972 outputs navigation data in any of several standard formats as required by the receiving, or "listener," device. The Output format option provides the following choices: · None turns the outputs off for when the 972 isn't connected to an external device. · NMEA 0183 Version 2.1 is a general-purpose interface output format used by most autopilots, radars, plotters, and other equipment. (NMEA 0183 Version 1.5 972 Installation Manual, Rev. B Page 25 SECTION SIX: Interfacing the 972 system sentences--BWC, GLL, and RNN--are included to allow backwards compatibility with marine equipment designed for this earlier version of 0183). Selecting NMEA output sentences When you select 0183 V2.1 as the output format (after pressing the EDIT menu key) and press NMEA output... to see a screen showing all the NMEA 0183 sentences the 972 can output. Three-letter abbreviations identify each sentence and are listed alphabetically. (For the meaning of these sentences, see the NMEA interface specifications document published by the NMEA.) The sentences to be output are followed by the word On; those that won't be output have two dashes indicating that they're off. Some devices can't handle all these sentences correctly, so you can customize the output here by turning individual sentences on or off. In general, you may want to turn on only those sentences used by the particular equipment interfaced to the 972. Turning NMEA output sentences on and off To turn on or off the 972's NMEA 0183 sentences, first follow the above description to display the 0183 sentence screen, then press the cursor pad to highlight the sentence you want to turn on or off, then press On/Off to toggle the sentence on or off. Repeat for each sentence as desired. When you're finished, press Return to go back to the Port Setup screen. If you want to set all the sentences to the factory settings for recommended output, press the Safe reset menu key. If you want to turn on only a select few sentences for output, press the All off menu key to turn off all sentences, then turn the desired ones back on. Choosing the talker ID The NMEA 0183 standard requires that the equipment you're interfaced to--the "listener"--knows what type of device is transmitting the data. The 972's talker ID tells the listener that it is receiving information from a navigation source, not a communications or sensor device--which transmits completely different forms of data. Certain listening devices will only accept navigation data identified as coming from specific types of equipment. The 972 lets you set its talker ID to GPS (GP), or integrated instrument (II) to match what the listener device is expecting: 1. Check the listener device's instruction manual to determine which "talker ID" codes it will respond to. Page 26 972 Installation Manual, Rev. B SECTION SIX: Interfacing the 972 system 2. At the Port 1 Setup or Port 2 Setup screen, press the cursor pad to highlight the NMEA 0183 talker id option, then press EDIT. 3. Scroll through the choices using the cursor pad to make your selection, and press ENTER. The interfaced equipment will now receive the 0183 data in the correct nav-source format. Choosing the lat/lon precision For more flexibility when communicating with a variety of other devices, you can set the precision level of the 0183 position information output by the 972. The choice you make depends on the equipment to which you're outputting the NMEA data (for the number of digits of precision required for that particular device, see the manufacturer's instructions). You have three choices: · XX.XX' (lat/lon precision to two decimal places (hundredths of minutes) or 60 feet) · XX.XXX ' (lat/lon precision to three decimal places (thousandths of minutes) or 6 feet; this is the factory setting) · XX.XXXx' (lat/lon precision to four decimal places (ten-thousandths of minutes) or roughly foot) The 972 conforms to the NMEA version 2.00 standard, and is also compatible with version 1.50. Electronic and pen plotting devices typically benefit the most from three and four decimal places of precision. However, many older devices (and some current autopilots) designed to operate with the original 0183 and other formats can only function with two-place precision. NOTE: Position information can be output and displayed to four decimal places, but the ability to actually navigate with such accuracy is limited by the accuracy of the Loran and GPS systems. Therefore, choosing more decimal places doesn't necessarily increase navigating accuracy. Choosing the output rate The default rate for standard NMEA 0183 output is two seconds. The 972 lets you use a one-second update interval, a rate of 1 Hz, under limited circumstances, for NMEA and diagnostic data output. Using the 1-Hz output option requires some thought when specifying NMEA 0183 (NMEA version 2.0). Because there isn't enough time to transmit a large number of sentences within one second, you must select for output only those that are needed. If you select more sentences than can be output in one second, the 972 displays the following error message: Sorry, can't do that. too many sentences for 1 sec interval In this case, you must select fewer sentences. If your application requires a longer update period, you can increase the span up to 999 seconds. Choosing the waypoint identification (ID) Many marine devices can display waypoint names if they're output by the 972. At the Port 1 Setup or Port 2 Setup screen, highlight the NMEA 0183 waypt id as option, then press EDIT. Change the option 972 Installation Manual, Rev. B Page 27 SECTION SIX: Interfacing the 972 system from NUMBER to NAME, and press ENTER when done. If capable, the listening device will now display six-character waypoint names. NOTE: Be sure to determine whether the listening device can accept waypoint names before you change the nmea waypt ID as option. Many older devices won't understand this identifier, and using it may cause problems with displaying waypoint information or when following routes. There is no standard for identifying how numbers should be assigned when converting waypoints from names to numbers. When you export waypoint information as numbers to a peripheral device, be aware that numbers aren't sequentially defined and may be re-used on a random basis. Choosing the checksum setting Some older devices may not accept sentences containing the NMEA 0183 checksum that's output by the 972. In such cases, the device may not work properly or at all. If you have problems interfacing to older equipment, you can turn off the NMEA 0183 checksum: At the Port 1 Setup or Port 2 Setup screen, press the cursor pad to highlight the NMEA 0183 checksums option, then press EDIT. Press the cursor pad to change the setting from On to Off, then press ENTER. Selecting an independent NMEA output-port datum You can adjust the geodetic datum for NMEA 0183 ports 1 and 2, separately from the datum you choose for position display. At the Port 1 Setup or Port 2 Setup screen, highlight the Output datum option, then press EDIT. Scroll through the choices to make your selection. To apply this chosen datum to the lat/lon coordinates in the NMEA 0183 output sentences, press ENTER. The standard GPS datum is WGS-84. Configuring the RS-232 port The RS-232 port on the NMEA connector is used to interface to a PC for downloading waypoints or for uploading 972 software updates. The following sections describe the RS-232 port's settings" To configure the RS-232 port: 1. Press STAR to display the Options/Service Info screen, then press Port setup options. 2. Press the cursor pad to select the RS-232 Port Setup line. The choices for configuration are: PORT OFF, D/B XFER, NMEA IN, COPY PORT1, or COPY PORT2. 3. Press EDIT. 4. Press the cursor pad to choose the desired function, and then press ENTER. Using "COPY PORT 1" and "COPY PORT 2" The copy port settings let you interface the 972 to most PC's without using an RS422-to-RS232 converter. This function copies the 0183 output of port 1 or port 2 to the 972's RS-232 port for direct Page 28 972 Installation Manual, Rev. B SECTION SIX: Interfacing the 972 system connection to the computer. A number of PC application programs can be used for waypoint/route loading, charting programs, data logging, etc. After checking that the desired port is outputting the correct data: 1. Press STAR to display the Options/Service Info screen, then press Port setup options... 2. Press the cursor pad to select the RS-232 Port Setup line. 3. Change the RS-232 setup option to display COPY PORT1 or COPY PORT2 by pressing EDIT, then pressing the cursor pad to change the selection, then pressing ENTER. The unit will now copy and output the specified port's data format through the RS-232 port to an external device. 4. To set the baud rate for the RS-232 port, press the cursor pad down to select the RS-232 Baud rate. Press EDIT, use the cursor pad to choose the baud rate, and press ENTER. NOTES: The RS-232 port may overflow (causing data loss) unless the port's baud rate is fast enough to handle the specified sentences. The 972 may display this precautionary message before you actually enter a new baud rate: warning: all sentences may not transmit at diag baud rate. Press "enter" to continue. In this case, select a slower output rate on the port setup screen of the NMEA port being copied, or remove sentences, or increase the baud rate. You must configure the PC and its software with the appropriate settings. Using the "PORT OFF" setting Use this setting to reduce the loading on 972's the processor when you don't need the RS-232 port's input or output functions. Using the Aux Port The 972's Aux Port is used to connect with the optional 491 echo sounder, or for transferring the database of routes and waypoints between the 972 and many older Northstar units. To wire the Aux Port for transferring waypoints see Figure 11 or Figure 12. Pin connections are shown in Table 11. 972 Installation Manual, Rev.

Press the cursor pad to choose Sounder, Database Transfer, or Port off, and then press ENTER. Connecting two Northstar units for database transfer You can connect a 972 to most older Northstar navigators and then transfer one of the unit's waypoints and routes into the other. (Northstar 972 units can share waypoints and routes between each other using the network). To connect the units, you must fabricate an interface cable and terminate both its ends with the supplied 6-pin solder-cup style cable connectors (P/N KS672). This data-transfer cable is not included. You must select a cable; use only shielded, twisted pair. To connect a 972 with a Northstar 952, 951, or 941, the older unit must be using software version 3.12 or higher. Assembling the cable To assemble the cable: 1. Cut the cable to the desired length. 2. Slide the following parts onto each end of the cable, in the following order: · connector backshell · rubber-strain relief boot that fits inside the backshell · twist lock (also known as a quarter turn), ensuring that it's facing in the correct direction. 3. Trim and prepare the wires for soldering to the connector body. 4. Terminate and solder the appropriate wires to the appropriate pins: Page 30 972 Installation Manual, Rev. B SECTION SIX: Interfacing the 972 system · For wiring a 972 to a 958 or 957, see Figure 11 and Table 12 on page 32. · For wiring a 972 to a 952, 951 or 941, see Figure 12 and Table 13 on page 33. 5. Slide the twist lock onto the connector body. 6. Screw the connector backshell to the connector body, and tighten. 7. Install the strain-relief clamp with two screws. 8. Connect one end of the cable to the Aux Port at the back of the 972, and the other end into the Aux Port at the back of the older unit. 9. Turn both units on, and configure both units' AUX ports to the D/B TRANSFER function as described above. Turn both units off and on again to initialize the ports. 10.
