17.2 Troubleshooting scenarios
Device Configuration Utility
is unable to establish a connection with the RF451/RF452:
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
Device Configuration Utility
.
Radios not networked together, not communicating:
1. Check the baud rate of all RF450s/RF451/RF452s; they should be the same.
2. Check Network IDs of all RF450s/RF451/RF452s; they should be the same.
3. Check Frequency Key Number of all RF45s/RF451/RF452s; they should be the same, unless
two branches of the network are operating in a parallel manner. See
network with parallel repeaters (using SubNet ID)
(p. 35) for settings used in a parallel
network.
4. If one or more radios are configured as repeaters, check the Repeaters Used box for all
RF450s/RF451/RF452s.
5. Check the PakBus® address of data loggers connected to RF450s/RF451/RF452s and in
LoggerNet
.
a. Check that antenna and antenna cables are correct for each radio type. RF451/RF452
radios use RPSMA (Reverse Polarity SubMiniature version A). RF450 radios use SMA
(SubMiniature Version A). SMA antennas will have a yellow heat shrink label to
distinguish them from RPSMA.
LEDs flash when
LoggerNet
command transmitted but no response from data logger:
1. Check SC12 cable on the data logger CS I/O port.
2. Check SDC address in RF450/RF451/RF452.
3. Check SDC address in data logger.
4. Check the baud rate of all RF450s/RF451/RF452s; they should be the same.
5. Check the baud rate of
LoggerNet
; it should match the baud rate of the
RF450s/RF451/RF452s.
