Page 25: Figure 5: Separation Distances Between Antennas
To avoid mutual interferences among different antennas on the vessel, refer to the drawing of recommended separation distances in Figure 5: ‘Separation distances between antennas,’ below. Figure 5 shows the minimum recommended distances for the separation of the GPS antenna from other antennas and physical mounting surfaces. Under normal circumstances, following these guidelines usually result in a relatively trouble-free installation. - Page 26 SECTION TWO - Installation antenna is desired. The AN205-P doesn’t require any ground and is porta- ble, an advantage when it must be moved from one vessel to another. The “combo” antenna should be located where it has a clear view of the hori- zon, but is not the highest point on the vessel.

SECTION TWO - Installation RF grounding The grounding system is an equal partner with the antenna in producing quality differential beacon signals for the 961 differential receiver. Lack of proper grounding can adversely affect differential signal strength, as well as SNRs, and is the most common source of problems with differential antenna installations. - Page 35 The 8410 ACU has a separate black ground wire inside the coupler base, this wire should be connected to an electrically quiet ground location. This wire is the AC signal ground connection from the antenna input cir- cuit. The purpose of bringing it out is to make available a separate signal ground path.

SECTION THREE - Interfacing Configuring the NMEA output ports Each output port can be programmed to meet most any special require- ments of devices that conform to the NMEA 0183—and other—data for- mat specifications. The service function described below allows the selection of the specific 0183 sentences that will be transmitted by the 961. -
Page 57: Figure 24: Port 1 Output Setup Screen
Check the installation instructions of the equipment to which you’re interfacing for any special requirements. The Northstar factory settings will be adequate for most peripheral equipment, but the following options are available, if needed: Parameter OUTPUT FORMAT (see below) NMEA 0183 Talker ID (see page 51) NMEA 0183 lat/lon precision (see page 52) - Page 58 SECTION THREE - Interfacing The unit will output navigation data in any of several standard formats as Setting the required by the receiving, or “listener,” device.

About the NMEA The 961 also supports the NMEA TLL sentence, sometimes referred to as the “rattle” sentence. This sentence allows the 961 to communicate its TLL sentence position to an interfaced radar device, which tracks a user-defined target. - Page 60 SECTION THREE - Interfacing 0183 identifier RNN V1.5 Modifying NMEA output sentences On the screen, the highlighted sentences will be output, as shown earlier in Figure 25. Some devices can’t handle all of these sentences correctly, so you can use this screen to customize the output by turning individual sentences on or off.

To set the output sentences to the factory default settings, press the DEFAULTS ON key. To turn on only a select few sentences, press the CLEAR ALL key, then turn the desired sentences back on. To modify the unit’s NMEA 0183 sentence output format, first follow the above description to display the 0183 sentence screen, then perform the following steps: 1. - Page 62 SECTION THREE - Interfacing 2. At the PORT OUTPUT SETUP screen, select the desired port, then 3. Press the EDIT key, and highlight the desired ID. 4. Press ACCEPT key (or CANCEL to leave the option unchanged).

The 961 normally uses a two-second update interval for data transmis- Changing the sion. Some applications require a longer update period, so the 961 lets output rate you increase that span to 199 seconds. You can choose a one-second interval, but at that rate, the bandwidth of 4800-baud NMEA data only allows the output of a reduced set of sentences. -

Changing GPS speed averaging value When you aren’t using DGPS or you’re out of range, you may notice that the SOG readings obtained from the GPS satellite system are slightly erratic, varying by up to several knots. The 961’s GPS SPEED AV function often can improve the steadiness of these readings, although you’ll see a slightly longer display-reaction time when the speed changes. - Page 70 SECTION FOUR - Service/Maintenance You can change the speed averaging value at any time without affecting other navigation functions. To change the speed averaging value: 1. At the RECEIVER INFORMATION screen, press the CURSOR PAD to 2. Press the CURSOR PAD left or right to select an averaging time in 3.
