1.0 INTRODUCTION TO INTELIMET ADVANTAGE 6
InteliMet Advantage 6 weather station is completely pre-wired, and assembled in a weatherproof
enclosure, including software to read data from weather sensors. Data is collected and stored in data
logger non-volatile memory. Up to 32,000 data points (85 days) can be stored in the data logger. Block
diagram of InteliMet Advantage 6 weather station logger is shown in the following chapters. Data logger
and weather sensors are supplied with a 4ft. metal pipe 1” in diameter. Crossbar is used for mounting for
weather transmitter, pyranometer mounting, leveling stand, and optional sensors if any as shown in the
figure below. Grounding rod, Lightening arrestor, and ground rod cables are required to protect system
from lightening surges. The InteliMet Advantage 6 weather station is a specially designed automated
system to record the critical weather parameters affecting the growth and harvest yield of crops.
Each station includes program for reading weather sensors, Lascano-Van Bavel Evapotranspiration (ETP)
for computing ETP in mm/hr. Crop growth models and Crop Water Index can be developed with this
information for grower applications of irrigation, pest control, and performing the optimum harvest. Many
other crop manager decisions can benefit from the hourly weather records, and current information.
Standard evapotranspiration modeling software is packaged with the InteliMet Advantage 6 weather
station. The purpose is to compute the potential evapotranspiration from short grass (ETP) in mm per hour
on an hourly basis. The algorithms are based on the method originally proposed by Penman, but with
several modifications by Dr. C.H.M. Van Bavel and Dr. Robert J. Lascano, that updated the procedure.

1.2 Communication Options
InteliMet Advantage 6 weather station based on CR200 logger offers a variety of communication choices
of user to connect between logger and PC using PC200 or PC400 or LoggerNet for advanced network
applications. Optional RS232, 150 to 250 ft RS232 extension cables can be added for direct
communication at 1200 baud. In addition, InteliMet Advantage 6 supports remote communication options
given below with easy to use software features.
(Model COM210) Land-line Modem for remote field retrieval and control:
Customer provides telephone connections and PC MODEM (Hayes compatible) at computer location.
Many models are supported by the telecommunication software package included in PC400 or LoggerNet.
(Model: SHM) Short haul modem for communication using 4-wire cable:
For cable communication of up to 4Miles not possible using 9-wire serial cable. DIP switch selectable.
Easy to install and establish communication. Short-haul modems are line-powered, i.e. powered from
communicating device PC or data Logger. Refer to sections 8.2 for a detailed discussion on Modem setup
and hardware required.
CR206 or CR216 Spread spectrum radio data transmission
(with Model: RFMX base station )Radio Modem
Stand-alone radio modems provide efficient and low-cost serial communication to remote installations for
long distances of up to 40 Miles @ 9600 baud rate. The CR206 operates at 915 Mhz in the USA, and
CR216 operates ate 2.4 Ghz in most other countries.
RFMX modems allow point-to-point and point-to-multi-point configurations between central PC and
multiple data loggers connected to it. RFMX modems can be setup using PC400 or LoggerNet software.
RFMX is also offered in a modem kit (Model: RFMXMK) with surge protector, high-gain antenna and
