Section 4. The RTDAQ Main Screen
4.2.3.1 Max Time Online
Note that the default Max Time On-Line setting for most communications
links is zero (“0 d 00 h 00 m”), which means that RTDAQ will never hang up
until you click Disconnect. For telephone links, the default Max Time On-Line
setting is 10 minutes in order to reduce the possibility of inadvertent and
expensive long distance or cellular telephone charges. There are, however,
other links that can result in expensive connection charges, such as digital
cellular links using TCP/IP that charge by the byte. Leaving the datalogger
connected also uses battery power, so if the datalogger power supply is not
recharged from a reliable source, it may discharge its battery below safe levels.
Be sure, therefore, that you do not leave the datalogger connected beyond the
time necessary to do the tasks you need to do.
4.2.4 Summary, Communications Test, and Clock Set
The Setup Summary step provides a list of the settings entered. You can use
the Previous button to go back and change settings as necessary.
The Communications Test step allows you to test the communications link
before going any further. If the datalogger is not installed, you can skip this
and the next two steps.
If communication succeeds, you can move to the Datalogger Clock step where
you can check or set the datalogger’s clock to match the PC’s system time. If
the datalogger is in a different time zone, you can enter an offset in hour and
minutes.
4.2.5 Send Program
The Send Program step allows you to send a program to the datalogger. This
may be a program you created with Short Cut, ProgGen, the CRBasic Editor
or a program supplied by someone else. Dataloggers will display the program
name if one is running and will provide table definitions that contain data
labels. If you don’t have a program for the datalogger you can skip this step
and send a program later from the Clock/Program tab.
If you connected to the datalogger during the EZSetup Wizard, when you leave
the Wizard it will ask if you wish to stay connected.
4.2.6 Editing and Deleting Dataloggers
Once you’ve added a datalogger, you may disconnect and use the other
datalogger configuration buttons on the Toolbar to delete that datalogger, edit
its settings, or add another datalogger to the Network Map.
