Application:
Allows to the race crew to see all the information that they
need.
Description
Is a sealed instrument to be installed at the
mast, and has four led back lighted LCD display, with four big
digits, 4 cm high, and 8 alphabetical characters of 1 cm high.
It
has a reinforced plastic cabinet, and a policarbonate window.
Using four buttons, one for each display, we can choose freely the information to be show in each display.
Is powered with 12 V and has three NMEA183 inputs, or 2 NMEA inputs and one SEA TALK input, also can display special information from the onboard computer, using a proprietary NMEA code.
The information displayed by the repeater varies accordingly with the use.

MAST REPATER

The instrument has four led back lighted LCD display, with four big digits and 8 characters each one. T
When you turn on the instruments display four shows the battery voltage and the other four the software version.
If the GPS is connected and running, the display 1 will show the time, the display 2 the speed in knots and the third the track
Pushing the button of each display, D1, D2, D3, y D4, they show in a ring the following information:
With a GPS connected:
SPD.' ;Speed in knots, is show ending with
KNT /REAL
'TRK.' ;Track. Is show as º
y TRK
'ERR.' ;Track error, shows how
far are of the ideal course to the destination way point in nautical
miles. Maximum 9 miles. Is show with mn and an arrow indicating the
correction direction.
'DIS.' ; Distance
to the destination way point, in indicated in nautical miles, ending
with nm. /DIST
'BRG' ;The bearing to
reach the destination way point, in grades, is show with º and
BRG
'VMG.' ;Velocity made good in
knots, is show with KNG/VMG
:
With a deep sounder connected
'PRF' ;Profundity in meters. Is show ending with mts/DEEP.
With a wind instrument connected
'WIS.'; wind speed in knots, Is sowed ending
with KNT/APAR
'ANG' ; apparent wind
angle. Is show with º Aw and an arrow indicating if comes from
starboard or port board.
With a knot meter connected:
WAS.' ;Speed toward the water. Is show as
KNT/WASP
TMP.' ;temperature of the water
in Celsius. Is show as ºCTMP
With an electronic compass connected:
'RMC.' ;Magnetic track in grades. Is show as ºCOMP
With a GPS in one input and a Wind instrument in the other
'TWS.' ;true wind speed in knots. Is show as
KNT/TRUE
'TWD.' ;True wind direction. Is
show asTRUE and an arrow indicating if cams from star board or port
board.
'WDN.' ;Wind direction toward the north. Is
indicated as ºWIND/NORTN
'VPP.' ;%
of the predicted speed (must be loaded the polar curve of the ship),
is show as %
'BAT' ; Battery voltage in volts. Show as
V
'CONT' The down counter, pushing the R buton reset the counter
'PRO' Information that comes from
the proprietary code.
The instrument accepts proprietary
information from the following sentence
$PDISP,n,xxxx,aaaa,bbbb
Where ‘n’ is the number of the display where we want to show the information
‘xxxx’, the digit or information with a symbol that could be ‘.’, ’º’, arrow to starboard or port board. Always must be a symbol, if the number is an integer without symbol you must insert a '.' at the end
‘aaaa’ Alphanumeric information of the first line
‘bbbb’ Alphanumeric information of the second
The indication of the left is showed in the display to indicated the function selected and remain until the information arrives.
ALARMS
If the battery voltage goes below 11 volts, it turns on the sound alarm and the display four shows Low Bat. Pressing any button turn off the alarm.
Installation
Manual
Mast Repeater
Connections
In 12 V must be connected the battery +
In 0V the Battery -
In input 1 must be connected the GPS output, NMEA + (High traffic
instrument), it has a 75 bytes buffer.
In the input 2 must
connected the wind instrument or knot meter. (Medium Traffic). It has
a 35 bytes buffer
In the 3 input must be connected the magnetic
compass, deep sounder. ( Low traffic). It has a 25 bytes buffer
In
0 V NMEA all the NMEA - or grounds
Output is the NMEA + output of
the computer. It has a 250 bytes output spool.
Alarm is an output
for an external alarm
Illumination is the input to turn on the
back light.
