Troubleshooting Radio Communications; Reducing Out Of Memory Errors; Resetting The Data Logger - Campbell CR300 Series Product Manual

22.5 Troubleshooting radio communications

Intermittent communications problems when connecting via radio, may indicate there is another
network in the area causing interference. To help remove the interference, use Device
Configuration Utility to change the Network ID and RF Hop Sequence in all RF407, RF412, and
RF422 radios within a network (standalone or included in a data logger) to another value. Each of
these settings must have the same value in all radios and dataloggers within a network. For
example, the Network ID in all devices could be set to 1726, and the RF Hop Sequence in all
devices could be set to 1. The Network ID can be any number between 0 and 32767. The RF Hop
Sequence can be any number between 0 and 7 in an RF407 or RF412 network; it can be any
number between 0 and 9 in an RF422 network.
NOTE:
Radio options cannot be mixed within a network. An RF407 can only be used with other
RF407-type radios, an RF412 can only be used with other RF412-type radios, an RF422 can
only be used with other RF422-type radios, and an RF427 can only be used with other RF427-
type radios.

22.6 Reducing out of memory errors

When the data logger gives an "Out of memory" error upon program compile, it means that
there is no unused continuous section of memory large enough to fit an element of the program.
The most common cause of this error is a large variable array. In that case, split the large array
into smaller arrays until the data logger compiler accepts the program.
See also Data memory (p. 88).

22.7 Resetting the data logger

A data logger reset is sometimes referred to as a "memory reset." Backing up the current data
logger configuration before a reset makes it easy to revert to the old settings. To back up the
data logger configuration, connect to the data logger using Device Configuration Utility, and
click Backup > Back Up Datalogger. To restore a configuration after the data logger has been
reset, connect and click Backup > Restore Datalogger.
