Overview

Cable considerations
To lessen the chance of picking up electrical interference where possible, avoid routing
the antenna cable (power and LAN lines) 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 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-

About wiring
• The length of LAN cables must be within 50 m.
• Use 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.
• Pass the cables through the specified clamp or the locking wire saddle.
• If a UPS (user supply) is connected to this equip-
ment, be sure that the grounding lamp does not
light.
• The output from the UPS must be a sine wave, as
shown in the figure to the right.
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 FAR-2xx7 series via LAN network, use the Gateway network.
• This unit does not support IGMP snooping or CGMP enabled switch.
• This unit does not have a router or repeater hub function.
• The Switching HUB HUB-100 does not support IGMP snooping or GCMP enabled
switch.
