SECTION SIX: Interfacing the 957 system
957 INSTALLATION MANUAL, Revision C1 Page 49
Connecting the
957 to a remote
display
The 957’s VGA connector is used to connect the 957 with a
remote display, such as the Northstar 1201. Northstar doesn’t
supply the connecting cable for non-Northstar displays because
the cable requirements vary with each particular installation.
The 957’s VGA connector accepts the 15-pin connector from a
standard VGA cable. Check the manufacturer’s instructions for
further details on the cabling and the setup. If you’re
connecting to the Northstar 1201, see the Northstar 1200 Series
Display Owner’s Guide (part number GM1200UG).
Connecting the
957 to a video
camera
The 957’s VIDEO connector is used to connect any
NTSC-compatible device, such as a video camera, to the 957.
Northstar doesn’t supply the connecting cable because the
cable requirements vary with each particular installation.
Check the manufacturer’s instructions for details.
After you’ve connected the 957 to the video device, check the
connection by pressing the VIDEO menu key (available on most
957’s screens) to see the video image on the screen. For
instructions on moving the image and changing its size, see the
Northstar 957 Operator’s Manual (part number GM957UG).
Connecting with a
radar device
The 957 can be set to interface with a radar device. The 957
supports the NMEA TLL sentence, sometimes referred to as the
“rattle” sentence. This sentence lets the 957 communicate its
position to an interfaced radar device, which tracks a
user-defined target. In turn, the interfaced radar device
communicates to the 957 the target’s position—in lat/lon
coordinates—so that you can see the target symbol, displayed as
a waypoint, right on the CHART screen (after you save the
position). The target symbol is displayed with the name
-RADAR on the CHART screen, as well as on both the ALPHA
and LOCAL waypoints lists. There, the radar waypoint is
displayed with the hours/minutes/seconds/day/month/year (for
example, 12:50:20-30JUN02) in the description field.
