Configuration Operation & Installation Manual
Depth - NMEA Input Control
This screen allows you to configure the depth unit (meters, feet, or
fathoms) for the
NAV 4 and TIDE 1 screens .
Depth information is accepted by the receiver from the NMEA 0183
data sentence DBK, DBS, DBT, or DPT on any input NMEA port.
Refer to the
Installation Section of this Manual for hardware interface
instructions.
Press the E key and move the cursor to the Echo Sounder Connected
line. Use the Change softkey to activate the input data options de-
scribed below:
Depth Unit - select between meters, feet, or fathoms. This data field
sets the depth unit displayed in NAV 4 and TIDE 1 , regardless of
whether a sensor is connected or not.
Echo Sounder Connected - causes the receiver to look for one of the
appropriate NMEA 0183 data sentences when set to Yes .
Data Input Port No. - Select the appropriate NMEA 0183 port that the
sensor is connected to (Ports 1& 2 for MK12/2 or Ports 1,2, 5-10
for MK12/8). Ports 3 and 4 are reserved for the MX421 antenna
controls.
Offset - Input the appropriate offset for the sensor, based on the mea-
surement you are most interested in. If your boat draws about the
same amount of water each time you use it, you may want to put in
the difference between the sensor and the height and the waterline
height. If your boat’s draw changes from one trip to another, as
would be the case when the receiver is used on a freight ship, you
may want to put in the difference between the sensor and the low-
est point of the ship’s hull.
Shallow Alarm Active - allows you to receive an alarm if the sensor
receives depth data lower than the limit you set in Alarm Limit
(below). The default setting is Yes .
