CRVW3 3-Channel Vibrating-Wire Datalogger

Use a temporary CRVW3 station and LoggerNet to validate the operation of
your deployed RF407 base station before leaving the site (see Section 10.5 ,
Base Station Deployment
(p. 76)
, above).
10.6 Repeater Station Deployment
A repeater station in a CRVW3 radio network can be either a CRVW3 station
configured as a repeater, or a dedicated repeater station.
To configure a CRVW3 station as a repeater station, follow the steps outlined
in Section 10.4 , Deployment of CRVW3 Radio Stations
(p. 74)
, but use an
omnidirectional antenna instead of a directional/Yagi antenna. Additionally, set
the Is Router setting located on the PakBus tab of the Settings Editor tab in
DevConfig to True . See Section 10.6.1 , Repeaters on RF451 Networks
(p. 79)
,
for additional configuration steps required when using the CRVW3-RF451 as a
repeater.
For dedicated repeater stations, the stand-alone radio that matches the radio
type of your CRVW3 stations should be used (RF407, RF450, RF451). Consult
the manual for that radio device for instructions on setting up and configuring a
repeater station. You should ensure that proper power, enclosure, grounding,
and mounting options are available for the station.
If CRVW3 end-nodes have already been deployed that rely on this repeater site
being installed and configured, you can test it before leaving the site (see
Section 10.3.2 ,
Field Deployment Considerations
(p. 73)
). Use a temporary base
station and laptop running LoggerNet to connect to one or more of the remote
CRVW3 sites through the repeater. (See Section 10.7 , LoggerNet
Configuration
(p. 80)
, for LoggerNet configuration details). Be sure to place the
base radio more than 25 feet away from the repeater antenna to avoid
interference. Validation of the repeater station by performing a test at the
permanent base station location is also recommended. Travel to the base station
location, and use the process outlined in Section 10.5 , Base Station Deployment
(p. 76)
, but use the remote CRVW3 (routed through the repeater) as the test
device instead of the local/temporary CRVW3.
10.6.1 Repeaters on RF451 Networks
When using a CRVW3-RF451 as a repeater station, ensure that the
Radio
Operation Mode setting on the Radio tab on the Settings Editor tab in
DevConfig is set to Point to MultiPoint Slave/Repeater . When using
slave/repeater devices in lab conditions, ensure each device is using an antenna
such as a ½ wave whip. Also see instructions in Section 10.6 , Repeater Station
Deployment
(p. 79)
.
When using a dedicated repeater station on an RF451 Network, use the RF451
radio as the main component of the station. Consult the RF451 manual for
details about the configuration of the radio as a repeater device
( s.campbellsci.com/documents/us/manuals/rf451.pdf ). See also Section 10.6 ,
Repeater Station Deployment
(p. 79)
.
10.6.2 Repeaters on RF407 Networks
When using a CRVW3-RF407 as a repeater station, the instructions in Section
10.6 ,
Repeater Station Deployment
(p. 79)
, cover all of the necessary
configuration steps.
