2.1 Overview
Cabling considerations
To lessen the chance of picking up electrical interference, avoid where possible rout-
ing the antenna cable (power and LAN) near other onboard electrical equipment (ra-
dars, TX radio antennas, etc.). Also avoid running the cable in parallel with power ca-
bles. When crossing with other cable, the angle must be 90° to minimize the magnetic
field coupling.
The antenna cable between the antenna, PSU 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
About wiring
• 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, FCR-2xx9, FMD-32x0 or FAR-2xx7 series via LAN net-
work, use the INS net-work.
• Use the optional USB cable (type: OP24-32) to connect to the USB port on the control
unit.
• The length of the USB cable should 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.
