    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 958 out of direct sunlight. See the figure below for additional mounting recommendations.
  • Page 8 SECTION TWO: Installing and wiring the 958 Regardless of the type of mounting, the 958 should be installed in an accessible location (dry) where the operator can easily use the controls and clearly see the display Regardless of the type of mounting, the location should have minimal glare from windows or bright objects.
  • Page 9 Flush mounting requires good ventilation behind the mounting panel. Poor ventilation will cause the 958 to overheat, which, in turn, may cause the display screen to darken. For overall width and height requirements, see the Northstar 958 Flush-Mounting Template (P/N GT958), which you can use to drill the mounting holes and cut the mounting panel in the exact recommended locations.

    The 2201 and 2301 are installed differently. The 2201 is mounted directly onto a standard antenna mount, and its cable is routed entirely on the outside from the external connector to the connector on the 958. The 2301 uses a mount with an extension, and the cable is routed through the inside of the extension.

  • Page 29 (see page 28) Choosing the output format The 958 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 958 isn’t connected to an external device.
  • Page 30 Turning NMEA output sentences on and off To turn on or off the 958’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 EDIT.
  • Page 31 The NMEA 0183 standard requires that the equipment you’re interfaced to—the “listener”—knows what type of device is transmitting the data. The 958’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.
  • Page 32 Some older devices may not accept sentences containing the NMEA 0183 checksum that’s output by the 958. In such cases, the device may not work properly or at all. If you have problems interfacing to older equipment, the 958 lets you 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.

    Connecting the 958 to a remote display The 958’s VGA connector is used to connect it with a remote display, such as the Northstar 1201 or 1202. Northstar doesn’t supply the connecting cable since the cable requirements vary with each particular installation.
