section.
9.4 CRVW3-RF407 Simple Network Installation
In a simple network installation for CRVW3-RF407 devices, an RF407 will be
used as the main component of the base station. Please refer to the RF407
manual for more information about the use of the RF407:
s.campbellsci.com/documents/us/manuals/rf407-series.pdf .
The RF407 will be coupled with an NL201 device to enable the TCP/IP or
internet connection. This allows the LoggerNet software to remotely drive the
RF407 base radio over the TCP/IP connection. In this way,
LoggerNet
can be
far away and out of radio range (at any location where reliable connectivity to
the internet is available), and still use the base station RF407 to communicate
with the CRVW3 devices on the radio network.

9.4.1 Deploying CRVW3 End-node Stations, Confirming Radio
Connectivity (CRVW3-RF407)
You should install individual radio-enabled CRVW3 devices at their field
locations by following the instructions in Section 8.2 , Field Deployment of the
CRVW3
(p. 33)
. Ensure that the CRVW3-RF407 is configured correctly using
DevConfig
. Do this from the Settings Editor tab in
DevConfig
. Choose the
Radio tab. Ensure that the Radio Enabled setting is set to True . Every
CRVW3 should use the same RF Hop Sequence and the same Network ID .
Press Apply if necessary.
After the CRVW3 has been installed, powered, and configured, you should
confirm that it can communicate over its radio (as described in Section 8.2.9 ,
Validating CRVW3 Radio Operation
(p. 49)
, and Section 8.1.7.2 , Validating
CRVW3-RF407 Radio Connectivity
(p. 31)
). Use a laptop running DevConfig and
a portable RF407 to complete this step.
From the CRVW3 location, confirm the line-of-sight path to the base station
site. Install a directional/Yagi unless the distance to the base station is very
short. Orient the Yagi antenna so that it points directly at the base station.
9.4.2 Base Station Installation and Validation (CRVW3-RF407)
Select a location for the base radio station that has good radio connectivity with
all the CRVW3-RF407 stations, as well as TCP/IP Ethernet access.
