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.)

*1:IEC61162-1
