SECTION 1 GENERAL INFORMATION
1.1 Function
By receiving GPS signals from up to twelve satellites, DGPS224 sensor provides highly accurate
position fixing. Furthermore, the DGPS224 can implement DGPS measurement by receiving the
correction data, and can achieve the measurement of high accuracy than the GPS measurement.
1.2 Features
•Built-In Beacon receiver
The DGPS224 can implement DGPS measurement by receiving the correction data from
Beacon station, and can achieve the measurement of high accuracy than the GPS
measurement.
•SBAS function
The DGPS224 can implement DGPS measurement by receiving the correction data from SBAS
satellite (WAAS/EGNOS/MSAS), and can achieve the measurement of high accuracy than the
GPS measurement.
•RAIM function
The accuracy of position fixes is self-tested by the equipment. (RAIM function)
This function assures higher reliability to the position fix than conventional method.
•Twelve-channel, twelve-satellite tracking, and all in view
Highly accurate position fixing is ensured by simultaneous tracking of up to twelve satellites by
twelve channels.
•Switching between IEC61162-1，NMEA0183 versions 1.5, 2.1 and 2.3.
The data output conforms to IEC61162-1 or NMEA 0183, and version switching is possible. This
feature allows the unit to be connected with various types of marine equipment including radars,
fish finders, and plotters.

SECTION 3 INSTALLATION
3.1 Unpacking and Checking
Take out the DGPS224 from the packing case carefully. Check each item listed in Table 1-1 is
contained in the case. Save the case and the packing material until the equipment will be installed
successfully. In case the equipment is to be returned, kindly use the kept packing material.
3.2 Locating the Position for Installation
When connecting the cable attached to the equipment, do not bend it
acutely, twist it, or impart excessive force. Doing so sometimes causes
cracks or damage to the coating, resulting in fire or electrocution.
Do not install the sensor where there is excessive vibration.
Vibration may cause sensor failure.
Do not paint the sensor.
Doing so may result in reception problems.
Install the sensor where there are no obstacles, in order to ensure that
GPS signals can be directly received from satellites without
interference or reflection of signals from surrounding objects.
Whenever possible, select a place with the following characteristics.
If it is difficult to find an ideal site, select a place temporarily and install the
equipment. Conduct a test to make sure that the proper performance can be
obtained and then fix the equipment in position. If it is installed at an improper
place, reception accuracy may be impaired.
1. An open space, which allows uniform reception of satellite signals.
2. Far away from any high power transmission antennas.
3. Outside radar beams.
4. Away from the INMARSAT antenna by at least 5 meters and outside the
INMARSAT beam.
5. Away from the antenna of a VHF transmitter and a direction finder
by at least 3 meters.
6. Away from a Magnetic Compass by at least 1 meters.
7. 3 meter or more away from amateur radio antennas.

3.3 Installation Procedure
3.3.1 Installation of the Sensor
The sensor base contains 1 inch 14UNS-2B screw holes. It can be attached to poles with cut male
screws, or off-the-shelf adapters.
(1) When performing attachment, always hold and turn the sensor base. Holding and turning the
radome may result in a large amount of force applied at the junction of the base and the radome,
resulting in damage to the sensor.
Do not apply force to the joint. Hold and turn the base.
(2) Secure the sensor cable in position with a clamp band as shown below to protect it against damage
due to vibration.
(3) When connecting an extension cable to the DGPS sensor, always seal with self-bonding tape in
order to waterproof the connector, and wrap this section with vinyl tape to protect it.

3.3.2 Installation of the Sensor to pass a cable through a pole
It is possible to pass cable into pole, when DGPS sensor attached to poles with cut male
screws. (1”-14 UNS-2A). In this case, Cable guard rubber (attached article) used.
(1) The cable is installed as following figure.
Do not bend the cable acutely. Doing so may result in damage to the cable.

3.4 Cable connection
3.4.1 Connection to Navigation Equipment that can be connected directly
CAUTION
When you connect the DGPS224 to the navigation equipment that is
possible to connect directly, confirm the type of connector and pin
arrangement beforehand. If the possibility of direct connection with
DGPS224 is not described in the manual of the navigation equipment,
confirm the all pin assignment. Incorrect pin connection may cause a
damage of the equipment.
When the DGPS224 is connected to directly connectable GPS navigation equipment, 12 VDC is
supplied from the equipment to the DGPS224. In this case, connect the 6-pin connector to the plug
where the GPS/DGPS label is attached on the rear panel of the equipment.
3.4.2 Connection to Navigation equipment that cannot be connected directly
CAUTION
Connect it taking care about the polarity of the power supply.
The faulty wiring might damage the DGPS224.
DGPS 224 is designed for the power supply of 12/24VDC.
If the power supply of over 40V is fed to the equipment,
It might be damaged.
Normally, the 12/24VDC power is supplied out of the DC power switchboard or main battery.
As the normal current of the equipment is approximately 0.15A, it is recommended using a fuse not
exceeding 2A in the power line.
When the initialization is not provided, leave pin 5 open.
Fig. 3.7 shows the connection with the equipment that cannot be connected directly.

3.5 NMEA Version Switching
When the equipment is shipped from the factory, the NMEA output version is set to the version 1.5. If
you want to change the output data, please carry out the following procedure:
1. Connect pin 4 and pin 5 of the connector.
2. Turn on the DGPS224.
3. The output data is switch.
(If procedures 1-3 are repeated, the output data is switched to NMEA0183 Ver1.5, Ver2.1, Ver2.3,
IEC*1 and Beacon correction data sequentially.)

Note. Each GSV sentence includes 4 satellites, so the number of GSV sentences varies based on
the number of satellites detected.

Therefore, if satellites in view are 12 GPS satellites and 1 SBAS satellite (total 13 satellites),
the GSV sentence is output only 11 GPS satellites and 1 SBAS satellite (total 12 satellites).

Note1. When this sentence is input, GPS sensor is initialized according to the items 10 to 15.
Note2. This sentence must be sent after this first data output when power is on or master reset is executed.
Note3. Setting of the flag have the following priority. When flags of both high and low priority set at the same
time, only a flag of high priority is executed. If flag of same priority set, flags are executed at same time.
