DataView II (CD295) Dual Line Display
8. Problems
• Symptom
The DataView II displays ‘Waiting’ in every location.
Explanation
This message indicates that the DataView requested a public variable from
the datalogger, but has not yet received a response.
Things to check
Is the DataView II connected to the datalogger?
Check the serial cable from the DataView II to the datalogger.
Does the datalogger have power?
Check the power supply to the datalogger.
Does the PakBus address of the datalogger match the ‘Logger Address’ in
the CD295?
Using DevConfig, check that the ‘Logger Address’ setting in the
DataView II and the PakBus address of the datalogger match (refer to
your datalogger manual).
Is the baud rate of the datalogger’s RS-232 port set to 9600 or auto?
By default, the datalogger’s serial port speed should be suitable for
the CD295. If it has been manually changed, it may need to be
adjusted.
Is this the right version of the DataView program for the datalogger
program?
It is important that the program that is running in the datalogger is the
same as the one used when the DataView II program was written. If
not, then the DataView II program may need to be re-written.
Could the datalogger be too busy to answer?
Consider the execution of the datalogger program, and modify if
necessary.
