System Configuration - Furuno WR2120 Operator's Manual

SYSTEM CONFIGURATION

The observation system consists of an Antenna Unit (ATU), a Signal Processing Unit (SPU), and a Data
Processing Unit (DPU)
1) ATU (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 SPU
2) SPU
This unit is a relay point of LAN cable (1000Base-TX Cat5e or better, must use STP (Shielded Twisted
Pair) instead of UTP (Unshielded Twisted Pair) even to switches on the power of the ATU).
3) DPU (indoor unit)
DPU displays 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 or operate them on DPU, because it will cause an out of system
resource problem. Only pre-installed application can be operated.
It is recommended to transport the observed data to the external storage, and then use WR_transfer
(pre-installed) to send data by FTP server to share the observation data with the software which is installed
in other PC.
