1.2 Mounting Considerations
In addition to the considerations described in this section, keep the length of the satellite compass
cable in mind when selecting a mounting location.
General considerations
Mount the satellite compass above radar mast
As shown in the figure below, mount the SC-33 satellite compass above a radar mast. This pro-
vides an unobstructed path between the satellite compass and the satellite, regardless of vessel
heading. Follow the procedure on the next page to choose an installation site.
Satellite compass mounted above antennas and structures
If satellite compass cannot be installed above radar mast
If absolutely impossible to do otherwise, the satellite compass may be installed below a radar
mast. However, certain guidelines must be followed to prevent the shading and multipath prob-
lems which occur as shown in the figure below. Follow the procedure on the next page to choose
an installation site.

Selecting the installation site
The installation site must satisfy the four conditions described in this section. After choosing the
site, determine installation height, following the procedure in the next section.
CONDITION 1: Locate the SC-33 away from masts that might prevent reception of the GNSS
signal
• Install the satellite compass where the field of view against zenith is at least ±85°. The installa-
tion site should be as high as possible, above masts, etc. which might interfere with reception.
• If the above condition cannot be satisfied, separate the satellite compass so that the horizontal
angle to the interfering object is less than 10°. Refer to the table below to determine minimum
separation distance.
CONDITION 2: Locate the SC-33 out of radar beams
• Locate the SC-33 more than 20° above the top of a radar antenna.
• Separate the SC-33 at least 3 m from an open-type radar antenna.
• If the SC-33 cannot be separated at least 3 meter from an open-type radar antenna, install it at
least 80 cm above the top of the radar antenna.

Separate the SC-33 from an Inmarsat Fleet Broadband Antenna by at least 3 m.
Separation distance from Inmarsat Fleet Broadband Antenna
CONDITION 4: Locate the SC-33 away from communication (VHF, etc.) antennas
Separate the SC-33 as far as possible from communication antennas.
CONDITION 5: Select a stable location with minimal or no vibrations from engines or waves
Install the SC-33 in a stable location. The SC-33 contains highly sensitive GNSS and angular
speed sensors. Therefore, try to install it where shock, vibration, etc. are minimal.

Installation height
After choosing the installation site, determine the installation height, considering composition of
the deck and surrounding area.
The deck is flat and metallic, or the area around the installation site is metallic
• If metallic surface is wider than the area of the top view of the SC-33, install the SC-33 at least
800 mm above the deck.
The deck is non-metallic (FRP, etc.) and there are no metallic objects around the
installation site
• If mounting surface is non-metallic and there is no radar or Inmarsat antenna in the vicinity,
mount the SC-33 directly on the non-metallic surface. This can be done provided the metallic
material support is smaller than the SC-33. If the SC-33 is to be fixed to a mounting pipe, choose
a site where there is less vibration.

1.3 Mounting Procedure
Note 1: The bird-repellent fixtures (optional supply) can be attached to the antenna cover to pre-
vent birds from landing on the cover. If it is more convenient to attach the bird-repellent fixtures
before securing the antenna unit to the mounting location, do step 6 below before fixing the an-
tenna unit.
Note 2: According to the installation location, connecting the antenna pig tale connector to the
NMEA2000 bus or a cable from an optional unit in advance is easy to fix to the location. Connect
a cable with reference to step 5 beforehand. Then, waterproof the connection.
1. As shown in the figure below, weld a platform (local supply) for which to mount the satellite
compass. The thickness of the platform should be 5 mm to 15 mm.
2. Orient the antenna unit to face the bow, referring to the figure above. The antenna should be
installed within ±2.5° of the bowline.
Note 1: Take care not to crush the cabling when mounting the antenna to the platform.
Note 2: Take care not to cover the vent hole on the antenna.
3. Secure the unit to the platform with four sets of M10 hex. nuts, spring washers and flat
washers (all included as installation materials) with 20 ±2 N•m torque.

4. Coat the exposed parts of the nuts, bolts and washers with the Adhesive TB5211 (included)
to prevent corrosion.
5. Connect the antenna pig tale connector to the NMEA2000 bus or a cable from the optional
unit, then waterproof the connection. See chapter 2 for the wiring and the waterproofing.
6. Remove the double-sided tape from the optional bird-repellent fixtures, then attach to the
antenna cover. Coat around the bird-repellent fixtures with the Adhesive TB5211 (included).
7. Fix the satellite compass cable to the pipe at suitable intervals with the cable ties (local sup-
ply).
Note: Create a loop in the cable close to the satellite compass and tie the loop with a cable
tie for maintenance work, as shown in the below figure.

Attention
• Do not loop the antenna cable.
• Do not bundle the SC-33 cable with radio equipment cables.
• When the above noise reductions are insufficient, adjust the squelch on the radio equipment.
2.1 NMEA 2000 Network Connection
Using the supplied cable assembly, connect the SC-33 pigtail cable (Micro style connector) to the
NMEA2000 network backbone.
The SC-33 connects to the devices in an NMEA 2000 network with a drop cable, which is
connected to a backbone cable w/T-type connectors. The backbone cable can be light or heavy
type. Attach a terminator at both ends of the backbone cable. Use a Micro-C connector to connect
to the devices. We recommended that power from the NMEA 2000 network be input at the center
of the backbone cable. For connection to the IF-NMEA SC Interface Unit, see its operator's
manual.
What is NMEA 2000 (CAN) bus?
CAN bus is a communication protocol (NMEA2000 compliant) that shares multiple data and
signals through a single backbone cable. You can simply connect any CAN bus devices onto the
backbone cable to expand your network on-board. With CAN bus, IDs are assigned to all the
devices in the network, and the status of each sensor in the network can be detected. All the CAN
bus devices can be incorporated into the CAN bus network. For detailed information about CAN
bus wiring, see “Furuno CAN bus Network Design Guide” (Type: TIE-00170) on Tech-Net.

Guideline for Connecting
Follow these guidelines when selecting a mounting location.
• Where the cable connectors and CAN bus/NMEA2000 connectors are subjected to moisture or
water spray, waterproof the connectors as shown below.
1. Wrap the connection point with a single layer of vinyl tape.
2. Wrap one layer of self-bonding tape over the vinyl tape.
3. Wrap two layers of vinyl tape over the self-bonding tape.
2.2 NMEA 0183 Network Connection
Optional interface unit IF-NMEASC is required when connecting with NMEA0183 equipment. For
IF-NMEASC, see the Operator’s Manual of the IF-NMEASC.
2.2.1 How to connect the Cable Assembly (FRU-NMEA-NFF-R15/30)
The installation of the other terminal connector and T-connector is not required because the
FRU-NMEA-NFF-R15/30 is the terminal resistance internal cable of 120 ohm.
Securing and waterproofing connections
• Where the cable connectors and CAN bus/NMEA2000 connectors are subjected to moisture or
water spray, waterproof the connectors as shown below.
1. Wrap the connection point with a single layer of vinyl tape.
2. Wrap one layer of self-bonding tape over the vinyl tape.
3. Wrap two layers of vinyl tape over the self-bonding tape.
Waterproof the connectors

2.2.2 How to connect the Cable Replacement Kit (OP20-50)
Use a waterproof relay box (JPBS06) to relay connection when connecting to the SC-33 with the
MJ-A10SPF0015-150C/300C cable used in SC-30.
1) Unfasten four washer head screws on the top of the waterproof relay box to remove the cover.
2) Fabricate the MJ-A10SPF0015-150C/300C as follows.
1) Cut the MJ-10 connector part. Expose inner vinyl sheath by approx. 40 mm. Be careful not
to damage inner shield and cores.
2) Cut unused wires (green, yellow and purple) to approx. 10 mm, then isolate them with vinyl
tape. Wrap the drain wire with a vinyl tube.
Note: Make sure the rubber bush and ring are oriented correctly (as shown in the figure
above).

shield and cores.
2) Wrap the drain wire with a vinyl tube.
