Q & A

4. What is the maximum cable length usable between each unit?
See page.1-9.
- Between Processor unit and Control unit: Max. 30 m
Between Processor unit and TR unit: Max. 100 m
(FAR-2xx7 and 2xx7S: 300 m when used with RJB-001 and thicker
antenna cable)
- Between Processor unit and Monitor unit: Max. 10 m
(The cable length of 10 m is allowed for the cable supplied with the
equipment. The DVI standard specifies 5 m. For further extending the
cable length, DVI-DVI repeater is commercially available.)
LAN cable: The longest length of optional cables is 30 m.
Note:
For connecting with 100BASE-T(100 Mbps), use the LAN cable of category
5, and 100 m at the longest.
5. How can I extend the LAN CA to 30 m or longer? (What is the maximum
cable length?)
When connecting with 100BASE FX using optical cables, the cable length up to 2
km is allowed. When extending an optical cable, the media converter that can
process signals in real time is necessary.
6. Can antenna cables for FR-1425 and FR-2120 be used for FAR-2127 and
FAR-2137S?
Cables for older types of radars RW-4873 (armored-cable RW-6895) can be used
with new-type IMO radar. There will be no problem if the cable length is 30 m or
less. Re-install wiring.
Note:
- Two cables of the older type are required for 24 V+/‐ power supply which
was not used for older types of radars.
- Although the new cable RW-9600 has fewer cores, it allows a larger current
capacity than the older types of cables (available only in 0.5 and 1.25 sq. mm
sizes) since the new cable size is a 1.5 or 2.5 sq. mm.
7. What types of the color LCD monitor can be used for connection?
See page.4-41 and 7-76.
Monitors compatible with SXGA are MU-120C, MU-155C, MU-200C, MU-201C
and. MU-120C and MU-155C are not compatible in terms of the display size.
For connecting with these monitors, make the setting of the DIP switch S1 on the
SPU board. Set “S1-#1” to OFF and “#2” to ON.
8. Can any number be assigned for the radar in the setting of [Menu] -> 0 -> 4 ->
4: RADAR NO.? See page.4-19.
Assign 1 to 4 to let the unit serve as Radar.
Assign 5 to 8 to let the unit serve as a sub monitor. Information on radars
connected to the LAN can be checked on the [ANT-X] box menu.
