APPENDIX A. FREQUENTLY ASKED QUESTIONS
A-2 PC208W, Version 3.0, Instruction Manual
CQR
This contains the radiotelemetry quality
numbers. (See the RF manual.) The
maximum size for the active file
(CQR$.LOG) is 100,000 bytes and one old
version is kept (CQRO.LOG).
IO$COMx
In this filename, x represents a COM port
number. These files use a hexadecimal
display of the actual characters sent and
received by the computer. This is normally
used by those familiar with the
telecommunications commands or dialing of
modems. This log is similar to the IO
display in the Low Level I/O Monitor
window. It is enabled/disabled in the
STATUS OF COMMUNICATIONS screen.
The maximum size for the active file
(IO$COMx.LOG) is 1,200,000 bytes. Ten
older versions are kept (IO0COMx.LOG
through IO9COMx.LOG). There are logs
for each COM port in use. If these log files
are enabled, they should be
monitoredeven with restrictions on size,
they can consume 13 to 14 MB per COM
port.
Why can’t I manually toggle the control
ports on my CR10(X)?
By default, all CR10(X) control ports are
configured as input unless configured as output in
the datalogger program using Instruction 20.
Because an input port cannot be turned off or on,
if you try to toggle the port, you will receive no
response and the checkbox will not accept an X.
Every time there is a telecommunications
error, a message pops up even though I have
minimized PC208W. How can I prevent this?
You can’t. PC208W may actually try again and
make the connection, but datalogger
communications and data collection are
considered important enough that other
applications should be interrupted.
How can I get PC208W to automatically start
when the computer is started?
Add the PC208W Icon to the startup folder on the
Windows desktop. Windows 3.1 users need to
make sure that Windows is started in the
AUTOEXEC.BAT file, too. You may want to
customize the icon’s properties to run minimized.
A.2 EDLOG.EXE
I closed a program file and there was
another file behind it.
With EDLOG it is possible for the user to open
multiple files at the same time. This allows one
program to be viewed while editing another or
for program instructions to be cut and pasted
between programs. Selecting FILE | OPEN,
FILE | NEW, or FILE | DOCUMENT DLD FILE
does not close any files that are already open.
Select WINDOW | TILE to have EDLOG
arrange all open files so they can be viewed at
once.
How do I document a .dld?
Select FILE | DOCUMENT DLD FILE. Then
select the .DLD file using the File Selection
window.
Documenting a .DLD file automatically creates a
new .CSI file. You do not need to use the FILE |
NEW sequence. The .CSI file is named
“Noname” until it is saved.
How do I access the Input Location number?
While the cursor is on an Input Location name
(i.e., LOC name field is highlighted), type <Ctrl>
and the left arrow cursor key to access the Input
Location number field. Usually this is not
necessary as EDLOG will automatically allocate
Input Locations. Pressing <F5> brings up the
Input Location Editor.
How do I add comments to the end of an
instruction line?
The END key will move the cursor and place a
semicolon at the end of the line. Comments
can then be added.
How do I index or change the sign of a
parameter?
To index a parameter, press the <F4> key.
Two digit (00) and four digit (0000) parameters
can also be indexed by pressing the “C” key.
Negative floating point numbers are entered by
typing the “-” key followed by the number.
What does redundant write mean?
EDLOG has detected that two instructions are
writing to the same Input Location. Writing to
the same location twice is valid but is often
