System Configuration - Furuno WR2120 Operator's Manual

SYSTEM CONFIGURATION

The observation system consists of an Antenna Unit (radome), a Junction Unit, and a Data Processing Unit
(indoor unit) is shown below.
(1) Antenna Unit (radome)
Radome is to provide protection for enclosed physical environment. Inside the radome, there is the antenna
that rotates and radiates the radio waves. The radiated waves are backscattered by particles on the
propagation path, return to the antenna, and are processed by RF converter to transfer the signals to the
Signal Processing Unit.
(2) Signal Processing Unit (storage box)
Signal Processing Unit is stored in the storage box, and processes received signals digitally. The digital
processed signals are transferred to the Data Processing Unit via 1000Base-TX (LAN). This unit is a relay
point of LAN cable (1000Base-TX Cat5e or better, it is recommend to use STP (Shielded Twisted Pair)
instead of UTP (Unshielded Twisted Pair) and switches on the power of the ATU. Do not exclude them
because of CE and FCC registration reason.
(3) Data Processing Unit (indoor unit)
Data Processing Unit is displaying radar data and operates the weather radar.
User needs to prepare the external storage device for recording the weather observation data if necessary.
DPU has 3 ports for the dedicated LAN connections; ATU/SPU (LAN1), Internet (LAN2), and MONI-CON
(USB-LAN adaptor).
Note: Do not install any software into DPU because it will cause an out of system resource problem.
