Repeater Frequency: Leave at “Use Master Frequency Key”
•
Receive SubNet ID: 15 (matches RF451)
•
Transmit SubNet ID: 15 (matches RF451)
•
Network ID: Same value as given for RF451 – must match (0 to 4095)
•
Radio ID: Leave at zero (must be unique/different from RF451 radio
ID, which should be 1).
Press
Apply
. Disconnect the USB cable from the CRVW3.
When testing deployed devices in the field, you may have already
assigned different
Radio ID
,
Network ID
, and
Frequency Key
values than those shown above. Make sure the
Network ID
and
Frequency Key
values match between both (all) devices and that
the
Radio ID
is unique for each device.
8.1.7.1.3 Using
DevConfig
to Connect to the CRVW3-RF451 Over the Radio
Position the RF451 and computer to be at least 25 feet away from the CRVW3.
The CRVW3 should no longer be wired to any device. Highlight
CRVW
Series
in
DevConfig
(not
RF451
). Choose the port on the computer that is
connected to the RF451 radio. Now Press
Connect
. Confirm red and green
flashes on the
RX/TX
LED of the CRVW3 and on the RF451 as radio
communications now occur.
If no other CRVW3-RF451 devices are on the radio network (i.e., powered or
in range),
DevConfig
connects only to the CRVW3 device that is powered and
available, using the RF451/COM port on the computer as a transparent link.
The
DevConfig
screens should act just as they do when the computer has a
wired connection to the CRVW3. You should be able to view and set all the
settings of the CRVW3 over the radio connection. Confirm that the
Serial
Number
and
Station Name
in the
Main
tab are correct and correspond to the
CRVW3 station being tested. Use the
Data Monitor
tab to confirm proper
CRVW3 operation.
If multiple CRVW3 devices need to be powered and located
within radio range of the RF451 base station computer, you must
use
LoggerNet
to test their radio connectivity.
LoggerNet
can
distinguish between CRVW3 devices based on PakBus address.
Each CRVW3 should have a unique
Radio ID
setting and a unique
PakBus address. Follow the steps outlined in Section
, to perform multiple CRVW3 radio
testing using
LoggerNet
.
8.1.7.2 Validating CRVW3-RF407 Radio Connectivity
When using CRVW3-RF407 devices, the simplest way to confirm connectivity
is to use an RF407 radio (
) connected to your lab
computer. The RF407 operates as the base station. (See Section
(p. 69)
, for more details about base station
considerations.)
