DGPS (Differential GPS) BEACON RECEIVER SETUP
You'll have to tell the UltraNav II which beacon receiver's data to
expect
and setup the parameters
for
that data. To do
this, first press the MENU
key, then
pressthe key
nextto the 'CHANGE GPS SETTINGS" label. Now
press the key next to the "SELECT NMEA" label. The screen on the
previous page appears.
Pressthe key nexttothe desired beacon receiver.
The beacon receiver is selected, now you'll need to set it up for the
frequency and bit rate of the station
you'll be using
in your area.
Repeat
the above steps
to
get
the NMEA screen as shown on the
previous
page.
Now
press
the
key
nextto the "SETUP BEACON" label. The
screen
shown below appears.
The station frequency and bit
rate are shown on the
right

of the screen. Press the key
adjacent to the INC FREQ" to
increase the station frequency
orthe DEC FREQ"to decrease
it. Do the same for the bit rate.
(NOTE: For automatic station
selection on the Starlink MRB-
2A ONLY, set the station fre-
quency to zero and ignore the
bit rate.) When the station frequency and bit rate are adjusted to their
proper settings, press the key next to the "EXIT' label. The UltraNav II

number, its frequency
and bit
rate, the "health' of the station
(0 = best, 5 = worst), signal
Pole Mount
First, thread the pole mounting adapter onto the
mounting pole or ratchet
base. Align the
pole
mounting adapter so the module will face the bow of
the boat. Install and tighten the set screw into the
pole mounting adapter
and tighten it securely. This should prevent the GPS module from
unscrewing from the pole. Place the gasket onto the pole mounting
adapter. Now attach the cable to the GPS module and pass the cable
through the gasket, pole mounting adapter, and pole. Set the OPS
module on
top of the pole mounting adapter and align
the four threaded
holes in the module with the holes in the pole mounting adapter. Using
the four stainless steel 5 mm screws and lock washers supplied
with the
UltraNav II, attach the pole mounting adapter
to the OPS module. This
completes the assembly.
If the
pole or mast you're using
isn't hollow or if the. hole in the middle of
the
pole is too small for the connectors, use the cable
mounting adapter
supplied with
your unit. Thread the cable
mounting adapter
into the GPS
pole mounting adapter. Then thread the pole into the cable mounting
adapter. Route the cable down the outside of the pole.
