2.1 Overview

Cabling considerations

To lessen the chance of picking up electrical interference, avoid where possible rout­ing the antenna cable (power and LAN lines) near other onboard electrical equipment
(radars, TX radio antennas, etc.). Also avoid running the cable in parallel with power
cables. When crossing with other cable, the angle must be 90° to minimize the mag­netic field coupling.

The antenna cable between the antenna and processor units is available in lengths of
15 m, 30 m, 40 m, and 50 m. Whatever length is used, it must be unbroken; namely,
no splicing allowed. Use the antenna cable as short as possible to minimize attenua­tion of the signal.

The radar must be connected to an emergency power source, as required by SOLAS
II-1.

About network construction

• Use the optional Switching Hub HUB-100 to connect the sensor networks. For the gate­way networks, use the optional Intelligent Hub HUB-3000.

• Do not connect the ship’s LAN network to the optional HUBs. Also, commercial PCs
cannot be connected to the gateway network, other than for maintenance.

• To connect the FEA-2xx7, FMD-32xx, FAR-2xx7, FCR-2xx9 via LAN network, use the
INS network.

About wiring

• Use the optional USB cable (type: OP24-32) to connect to the USB port on the control
unit.

• The length of the USB cable must be within 5 m to prevent equipment trouble.

• The length of LAN cables must be within 50 m.

• Use the Cat5e or Cat6 LAN cable for the network if available locally.

• If LAN cables are not available locally, use the optional LAN cables (FR-FTPC-CY for
sensor network, DTI-C5E350 VCV for gateway network).

• If extension or division of the DVI or RGB cables is necessary, use the dividers shown
below.

• DVI cable divider: DVI-12A (maker: IMAGENICS)

• RGB divider: CIF-12H, DD-106 or WBD-14F (maker: IMAGENICS)

• Make sure that the ground wires are connected between the ground terminals on each
equipment and the ship’s earth.

• If a UPS (user supply) is connected to this equip­ment, be sure that the grounding lamp does not
light.

• The output from the UPS must be a sine wave, as
in the right figure.

Standard wiring

A Cat 5e LAN cable (RW-00135) connects between the antenna unit and the PSU.
The maximum length of the cabling between the Processor Unit and the antenna unit
is 80 m.

Retrofit (using antenna cable RW-4873/6896/9600) or foremast installation is also
possible, with the installation of a pair of LAN Signal Converters, one in the antenna
unit, the other in the PSU. See section 2.7.

Three cables are connected to the antenna unit: antenna cable, cable for the sub mon­itor (option) and power cable for the deicer (option). The procedure shows how to con­nect all cables. Disregard the descriptions for the optional equipment if not applicable.

2.2.1 How to fabricate the cables

Antenna cable RW-00135

The end of the antenna cable RW-00135 which connects to the antenna unit is pre­fabricated.

If there is a chance of inclement
weather when the transceiver unit is
removed, cover the intake on both
covers with packing tape. Be sure to
remove the tape after completing the
installation.

Some parts or wiring have been omitted from the illustrations for clarity.

1. Unfasten four bolts from the rear cover to remove the rear cover. If the deicer is
already installed or will be installed, remove two bolts inside the antenna to enable
removal of the front cover. See Note 2.

Note 1: The cable for the performance monitor is connected between the rear
cover and the RF-TB Board in the antenna unit. Open the cover slowly to prevent
damage to the cable and connector.

Note 2: If the deicer is to be installed, spread open the right and left heater ele­ments on the cover, then remove the front cover, being careful not to hit the ele­ments on the radiator or chassis.

Note 3: If this a retrofit or foremast installation, a LAN Signal Converter is re­quired, in both the antenna unit and the power supply unit. See section 2.7.

Note: The orientation of the cable entrance assy. can be changed, in one of the
three orientations shown in the figure below. No other orientation is allowed, to
maintain watertight integrity. The default orientation is “deck”. To change the
entrance, unfasten the four screws circled in the figure below, then orient the ca­ble entrance assy. in the required direction. Refasten the screws.
