6.5 FM-8500 Installation
Refer to the
Installation Manual, FM-8500
6.5.1 Transceiver
There are two FM-8500’s in the standard console configurations. One unit is
mounted in the console, and will not require installation of a NMEA cable or
power cable. The handset and hanger, for the console mounted FM-8500, must
be mounted in a location that is convenient for the user. The second unit is
remotely mounted on the bridge, and will require the installation procedure
listed below.
1) Mount the transceiver bracket (Refer to Pg. 10 of the
Installation Manual
).
2) Screw the knob bolts with washers into the transceiver unit.
3) Set the transceiver unit into the mounting bracket and tighten the knob bolts.
4) Make a power cable using the supplied connector (000-503-281). Install from the
transceiver, 24VDC port to TB2(-) and TB3(+) in the Meter Box Assembly.
All power connections outside the console must be protected with inline fuses.
The FM-8500, which draws 7 amps, will require a 10-gauge wire for up to
40 feet separation from the Meter Box Assembly.
5) Make a NMEA cable using the supplied connector (000-111-537). Connect
from the
NMEA
port on the transceiver to the IC-315 Junction Box.
Use Belden 8302 or equivalent cable.
(Refer to Pg. S-6, the
Felcom 15, IC-315 Junction Box Connections
)
6) Attach a ground strap from the transceiver ground stud to the ship’s hull or
ground system.
7) Mount the handset hanger and connect to the
HANDSET
port on the transceiver.
6.5.2 Antennas
Two standard marine VHF antennas are necessary for both FM-8500’s. One antenna
is the main TX/RX antenna while the second is the channel 70 RX antenna for the
DSC receiver.
1) Mount both VHF antennas. Make sure that they are separated vertically to
prevent the TX antenna from interfering with the channel 70 RX antenna.
2) Install the cables and connect the transmit antenna to the
ANT
port and the
receive antenna to the
CH 70 ANT
port on the transceiver.
