WIRING

2.1

Interconnection

Wiring consideration
To lessen the chance of picking un electrical interference, avoid where possible rout-
ing the signal cable near other onboard electrical equipment (radars, transmitting ra-
dio antennas, etc.). Also avoid running the cable in parallel with power cables. When
crossing with other cable, the angle should be 90° to minimize the magnetic field cou-
pling.
The signal 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 signal cable as short as possible to minimize attenuation
of the signal.
The radar should be connected to an emergency power source, as required by SO-
LAS II-1.

Notice for the 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 LAN network on board to the above optional HUBs. Also, com-
mercial PCs cannot be connected to the gateway network, other than for mainte-
nance.
• When connecting the FEA-2xx7 or FAR-2xx7 series via LAN network, use the INS
network.

Notice on wiring

• Use the optional USB cable (type: OP24-32) to connect to 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 should be within 50 m.
• Use the CAT5E or CAT6 LAN cables 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 ERGB cables is necessary, use the dividers
shown below.
• DVI cable divider: DVI-12A (maker: INAGICS)
• RGB divider: CIF-12H, DD-106 or WBD-14F (maker: INAGENICS)
• 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.
