THE RF RTU SYSTEM
GENERATION III, IV, IV.V
1.
SYSTEM OVERVIEW
The RF RTU system is designed to work in conjunction with the DREAM irrigation
control system, with the UNILINER, MINILINER and OASIS systems, enabling them
to reach remote Input and Output (I/O) devices by wireless means.
Generations GIV and GIV.V were developed after GIII in order to improve the
frequency separation ability and to cover different frequency ranges. GIII, GIV and
GIV.V are not compatible. The picture below shows the RF units of the three kinds.
Remember - in the same system all RF units must be of the same type:
The RF system consists of the following parts:

All the communication with all the RTU
units on site, goes through the RF
MASTER, therefore it should be carefully
positioned at a place from where it may
have a clear line of sight to most of the RTU
units.
