Why can't
I connect to my dataTaker?
If you cannot
connect to a dataTaker, do the following:
Check the configuration:
• check
that the baud rate is correct for the dataTaker.
• check correct
Comms Port
• use
Auto Baud Detect Fast and re-try the connection
• use
Auto Baud Detect Slow and re-try the connection. Check
the physical connection:
• check
that the cable and connectors are correctly installed
• check cable is correct one
• use
a terminal program (like DeTransfer) and send a simple command
to the dataTaker
(like STATUS). Check
the logger is suitably powered. If the logger has been out of use for
a long period of time then it may be
necessary to disconnect the battery for thirty seconds. The battery discharge
may have resulted in the dataTaker being unable to reliably restart its
processor.
See also the Getting Started with dataTaker user's guide.
Errors
sending programs If you have
problems sending programs to a dataTaker, do the following:
• if
the error is in the program, check the program and re-send it
• check
the cable and connectors
• do
a software disconnect from the dataTaker, reconnect, then send the
program again. (Note that
this software procedure of disconnecting, reconnecting, then sending
the program again is a valuable troubleshooting technique.)
If that fails, quit DeLogger, restart the computer, start DeLogger
again, connect again and re-send the program.
You may also need to manually reset the dataTaker (described in the Getting
Started with dataTaker user's guide supplied with your logger).
Programming
How
is a channel assigned to a Channel Expansion Module (CEM)?
1. First define the channel in the program builder window with any channel number.
2. Select the channel pop up menu by pressing the Right Mouse Button
on the channel icon, and navigate the menus to channel number (channel
options > channel number).
The menu will allow selection of the dataTaker or one of two CEMs.
3. Select the desired CEM and then a channel number to apply it to the channel.
If the CEM is attached the channel icon will reflect the new channel number.
Data Handling
Why
doesn't the data coming back from the logger change
when I modify the program?
When the program is modified
in the program builder window, the program must be sent to the logger
for the changes to take effect.
I
have a span defined but my data does not get converted. Why?
Each channel that needs to be converted must have the span applied.
1. Select the channel pop up menu by pressing the Right Mouse
Button on the channel icon, and navigate the menus to span
(channel options > data conversion > span).
2. Select an available span to apply it to the channel.
A box will appear with the channel in the program builder window to indicate
that the span has been applied.
When
I define a channel variable it always comes up as 1CV. How do I change
the channel number?
Select the channel
pop up menu by pressing the Right Mouse Button on
the channel icon and navigate the
menus to internal properties (channel options > internal
properties). The channel number can be modified
within the dialog.
Another way is to select the properties of the expression icon attached to the
channel variable by pressing the Right Mouse Button. The channel number can be
modified on the CV tab dialog.
Data Display
There
are no channels defined for use in my charts or forms even though
I have defined the program. Where are the channels?
The program has not been sent
to the dataTaker. Until this is done DeLogger will not make
the channels available for use in charts or forms.
A
defined chart or form isn't changing. Why?
Forms will not display
incoming data in edit mode - Check the window title contains
'(Edit)'.
Exit edit mode by selecting the form menu from the main menu bar and deselecting
Edit Mode.
OR
The chart or form is paused - indicated by a depressed Pause button. Press the
pause button again to resume displaying data - forms must first be out of edit
mode.
How
do I create new chart or form window?
Press the New button on the main
menu bar and select the desired window.
Charts
There
are no channels defined for use in my chart even though I have defined
the program. Where are the channels?
Make
sure the project (site) and schedule are selected in the Site
and Schedule tabs of the Chart Channels dialog box. All channels
relating to that schedule in the project will then be available.
Text Window
The
displayed information in the text window is not readable, how is
the format changed?
Press
the
" ? " icon button in the text window and select "Text Format".
When
I open the Text window to import an existing file all the buttons
are greyed out including the DLP button. How do I import the file
into the window?
Make the window active
by clicking anywhere in the window. All buttons will become active.
When
I send a program using send all in the text window the program does
not immediately start running. Why?
When a program is sent
from the text window, the dataTaker is halted by default. To start the
program issue a 'G' in the text command window or press Run on the main
toolbar.
When a program is sent from the program builder window the new program will start
running.
Forms
How
do I put a channel into a form?
Make sure the form
is in edit mode and double click on the row number. Select the desired
channel.
How
do I remove a channel from a form?
Double click on row number,
highlight the channel and press the Clear button.
Replay
After
selecting a replay file pressing the Play button on the replay console
does not display data on the chart. Why?
Before pressing Play on
the replay console, you must select the replay site in the Chart Channels
dialog box as well as the schedules and channels to be charted.
On
pressing Play on the toolbar with the Chart Channels dialog box open
the replay site is not available.
Close and reopen the Chart
Channels dialog box and the replay site will be present.
Resource Management
Number
of open applications
For most reliable operation
during a logging session, have only DeLogger running on the computer.
Close all other applications.
Open
windows
For most reliable operation
during a logging session, close any DeLogger windows that are not
required (including the Program Builder window once the program has been
sent).
Performance
problems during unload
If using a lower specification
machine and you are experiencing performance problems during an Unload
operation, try reducing the number of Form Views that are being actively
displayed.
To improve performance you can also set the type of computer and how
much data is sent. Changing these setting are under File and then click
on Performance.
Miscellaneous
What
does the "integrity check" menu
item do?
It ensures that the program
in the dataTaker is 'known' to DeLogger so that and displayed data
is correctly interpreted. It is most useful when connecting to more than
one dataTaker without exiting DeLogger.
How
do I open a closed window?
Press the Proj button on
the main menu bar, select the desired window and press Open.
How
do I create new chart or form window?
Press the new button on
the main menu bar and select the desired window.
How
do I export data into an Excel spreadsheet?
This can be done in real
time, or from a replay file.
In real time:
1. Select the text window and press the Display button.
2.Select "CSV Format" and clear any previously
displayed data.
