QUESTIONS AND ANSWERS.
Q
The display is blank and there is no red light on the data control box.
A
Check you have a 12 vote supply with correct polarity. (Positive to the
centre pin of the power plug.) Check the fuse (One amp.)
Q
The red light glows on the data control box but the display is totally blank.
A
Check the connections between the display and the data control box.
Q
The red light glows and the display shows only a letter phi (A circle with a
line through it.) at the top right of the screen.
A
The data control box is waiting for NMEA at the selected input channel.
Q
I cannot get data from one or more of the input channels.
A
Put the unit into test mode and read the sentences received on that
channel. If no sentence is shown the the unit is not receiving NMEA data
on that input. Check the wiring and check the sender is set up to send the
NMEA sentence you desire.
Q
I can read NMEA sentences on an input channel but cannot get that
channel to display NMEA data.
A
Check that at least one of the available sentences is capable of being
displayed by the Yacht Repeater. If the available sentences are not
compatible then e-mail NASA Marine with ALL the following information;-
(1) The manufacturers name and type number of the sending instrument.
(2) A list of all the NMEA message types shown on the problem channel.
(3) The software issue number of the Yacht Repeater.
Q
The LED on the remote control does not flash when a key is pressed.
A
Check the state of the batteries and check they are correctly installed.
(Note the centre battery is the opposite way round to the outer pair.)
Q
Why is there a delay in receiving some data displays.
A
NMEA data is generally updated every second so any delay should not be
more than two seconds. Some senders have a power saving mode which
send our data less often. If this is troublesome then set the sender to
normal operation.
