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.
• 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.
• When you use IEC61162-450 compatible sensors, set [Transmission Group] on the
[Common Installation Settings] menu. See the Instruction Manual (E42-01204-*)
fordetails.
• When connecting two or more FAR-2xx7 series radars, via the HUB-3000, to a
FAR-3000 series radar, the HUB-3000 IGMP querier function must also be setup.
See the Instruction Manual for the HUB-3000 IGMP queirer.
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.
