1INTRODUCTION
1.1 About this Manual
This manual, together with the Operator’s Manual, provides in-depth
information to facilitate installation of the C-Nav1000 R4 Navigation
System
The C-Nav1000 R4 Navigation System is available in two system
configurations: GPS and DGPS. This manual is valid for both
configurations.

INTRODUCTION Page 2
1.2 System Overview
Figure 1-1 shows an overview of the R4 Navigation System. The R4
Navigation System is available in two configurations: GPS and DGPS. Both
configurations feature an R4 Display. The GPS configuration also features
an R4 GPS Navigation Sensor and an MGA-2 GPS antenna, while the
DGPS configuration features an R4 DGPS Navigation Sensor and an MGL-
4 combined GPS/Beacon antenna.
The R4 Display provides a graphical interface to the system. Via the display
it is possible to create, edit and modify routes and waypoints, navigate
following a route, plot the current route as well as perform other
navigational functions.
The R4 GPS Navigation Sensor features a high-precision GPS receiver,
capable of receiving WAAS, EGNOS and MSAS differential corrections.
The R4 DGPS Navigation Sensor has all the features of the GPS Sensor, as
well as a dual channel beacon receiver for reception of IALA beacon DGPS
corrections. Both the GPS and the DGPS Navigation Sensor perform
continuous RAIM calculations according to the IEC 61108-1 (2nd edition)
standard (see Ref. [5]).
The Navigation Sensor is connected to the antenna, either an MGA-2 GPS
antenna or an MGL-4 combined GPS/Beacon antenna. The MGL-4 antenna
is capable of receiving both radio beacon and satellite signals.
Together the R4 Display and R4 Navigation Sensor provide three
configurable serial user ports, of which two are bidirectional and one used
for output only. There is also one binary Speed Log output port, one Alarm
output port and one Alarm Acknowledge input port.
For more details, see sections further on in this Installation Manual.

When mounting the R4 Navigation System it is recommended to follow the
steps as described in this Installation Manual. Details of the installation
procedure are found in the coming sections of the Installation Manual.
Recommended installation steps:
1. Mount the R4 Display (section 4.1)
2. Mount the R4 Navigation Sensor (section 4.2)
3. Mount the antenna (section 4.3)
4. Connect the R4 Display and R4 Navigation Sensor (chapter 5)
5. Power up the system (section 6.3)
6. Perform system functional check (section 6.7)
7. Configure output sentences (section 6.8)

MOUNTING Page 6
4.1 Mount the R4 Display
4.1.1 Location
The R4 Display should be mounted close to the position from which the
ship is normally operated, preferably on the bridge console close to the
conning position.
When mounting the R4 Display please consider the following:
•The temperature and humidity should be moderate and stable, +15ºC
to +35ºC.
(Operating temperature: -15ºC to +55ºC.)
•Select a location away from excessive heat sources.
•Avoid areas where there is a high flow of humid salt air.
•Avoid places with high levels of vibrations and shocks.
•Avoid mounting the R4 Display in direct sunlight.
•Ensure that there is enough airflow to avoid high ambient
temperatures.
•Ensure that the cables can be connected without violating their
maximum bending radius.
•The unit can affect magnetic compasses. The minimum compass safe
distance is 0.6 meters to a standard magnetic compass and 0.3 meters
to a steering magnetic compass.

4.1.2 Physical Size and Mechanical Drawing
Figure 4-1: Mechanical drawing R4 Display
4.1.3 Gimbal Mounting
1. Determine where to install the R4 Display. The R4 Display can be
mounted horizontally or vertically. Make sure there is enough space
around the R4 Display, see Figure 4-2 below.

MOUNTING Page 8
Figure 4-2: Gimbal mount clearance area
2. Fasten the gimbal mount on a flat surface with three screws, see Figure
4-3 below. The type of screws has to be chosen considering the panel
material. Note that the slots on the end of the gimbal mount have to face
the direction in which the R4 Display is to be mounted.

MOUNTING Page 9
Figure 4-3: Gimbal mount
3. Slide the R4 Display into the slots on the end of the gimbal mount.
Secure the R4 Display onto the gimbal mount using the locking knobs
without over-tightening.
4. Attach the signal cable (18 pin plug) and the power cable (3 pin socket),
as described in section 4.1.5.
5. Adjust the viewing angle after first loosening the gimbal locking knobs.
Securing the R4 Display without over-tightening the gimbal locking
knobs.

MOUNTING Page 10
4.1.4 Panel Mounting
1. Determine where to install the R4 Display, see Figure 4-4 below for
dimensions. Make sure that there is enough depth behind the panel, see
Figure 4-5. Please note that the signal cable has a maximum bending
radius of 10 centimeters.

Figure 4-4: Panel mount frame dimensions
Figure 4-5: Clearance distance behind the display
2. Make one rectangular hole and four round holes in the panel, as
illustrated in Figure 4-6. (If the hole template is available, place the
template in the right position and drill and saw according to the
template. If this method is used, exclude step 3 and 4 in this
instruction.)

MOUNTING Page 11
Figure 4-6: Panel mount hole dimensions
3. Place the panel mount frame in the rectangular hole and mark the
location of the four screw holes in the bedding.
4. Remove the panel mount frame and drill four screw holes where
marked in the panel.
5. Place the seal onto the back of the R4 Display. Make sure that it aligns
with the R4 Display body. Place the R4 Display in the panel mount
frame. Press the R4 Display and the frame together and install the two
securing screws, one on each side of the R4 Display.
6. Attach the signal cable (18 pin plug) and the power cable (3 pin socket),
as described in section 4.1.5.
7. Slide the R4 Display with the panel mount frame into the rectangular
hole in the panel and fasten it to the panel with four screws, as
illustrated in Figure 4-7 and Figure 4-8 below.

MOUNTING Page 13
4.1.5 Cabling
Use the cables included, one for power supply and one signal cable for
connecting the display to the R4 Navigation Sensor, external systems and
sensors. Note that the signal cable requires a minimum bending radius of 10
cm.
Connect the R4 Display Power Cable, marked “7000 108-132”, and the R4
Display Signal Cable, marked “7000 108-133”, to the corresponding
ConXall connectors on the back of the R4 Display. See Figure 4-9 below
(illustrating a gimbal mounted R4 Display).
Wire the open end of the cables as described in section 5.2 and Appendix
[A.8].
Figure 4-9: Connecting the power cable and the signal cable to the R4 Display
Note: The Signal cable for connecting to the R4 Display and the Power and
Data cable for connecting to the R4 Navigation Sensor both use 18 pin
connectors. Make sure they are not interchanged! The R4 Display Signal
cable is marked with “7000 108-133” and can also be identified by the fact
that only 13 pins are mounted in the male connector.
4.1.6 Power Supply
The R4 Display can be connected to an emergency power source. If
connected to an emergency battery, a re-calculation must be made for the
battery capacity. For power consumption, see section 8.1.
The R4 Display is designed to operate on 24 VDC. The nominal power used
is 8.5 W. The R4 Display shall be externally fused (slow blow fuse) with a
2 A fuse.
Install according to section 5.2 and Appendix [A.8].

MOUNTING Page 14
4.2 Mount R4 Navigation Sensor
4.2.1 Location
When mounting the R4 Navigation Sensor please consider the following:
•Mount the unit so that the LEDs can be observed if needed for
troubleshooting purposes.
•The temperature and humidity should be moderate and stable, +15ºC
to +35ºC.
(Operating temperature: -30ºC to +70ºC.)
•Select a location away from excessive heat sources.
•Avoid areas where there is a high flow of humid salt air.
•Avoid places with high levels of vibrations and shocks.
•Ensure that there is enough airflow to avoid high ambient
temperatures.
•Ensure that the different cables can be connected without violating
their maximum bending radius.
•The unit can affect magnetic compasses. The minimum compass safe
distance is 0.6 meters to a standard magnetic compass and 0.4 meters
to a steering magnetic compass.
