9.2 Troubleshooting Scenarios
DevConfig
is unable to establish a connection with the RF451:
1. Check that all other Campbell Scientific software is closed.
2. Check power to the radio. The Status LED should be flashing green if
12 volt power is supplied or red if only USB power is applied.
3. Check USB cable connections.
4. Check serial port assignment for DevConfig .
Radios not networked together, not communicating:
1. Check the baud rate of all RF451s/RF450s; they should be the same.
2. Check Network IDs of all RF451s/RF450s; they should be the same.
3. Check Frequency Key Number of all RF451s/RF450s; they should be
the same, unless two branches of the network are operating in a
parallel manner. See Appendix B.3 , Example 3: PC-to-RF Network
with Parallel Repeaters (using the SubNet ID)
(p. B-5)
, for settings used
in a parallel network.
4. If one or more radios are configured as repeaters, check the Repeaters
Used box for all RF451s/RF450s.
5. Check the PakBus® address of dataloggers connected to
RF451s/RF450s and in LoggerNet .
a. Check that antenna and antenna cables are correct for each radio
type. RF451 radios use RPSMA (Reverse Polarity SubMiniature
version A). RF450 radio us SMA (SubMiniature Version A).
SMA antennas will have a yellow heat shrink label to distinguish
them from RPSMA.
