SECTION 3. GRAPHTERM

3.2.6 P -- CREATE POWER-UP PROM
The P option is available for the CR10 and 21X
with special software. This option creates a file
that contains all the PROM software plus the
current datalogger program. When the file is
burned into a 27C256 (for CR10) or 27C64 (for
21X) PROM and placed in the appropriate
datalogger, the datalogger will power-up
programmed and logging.
THE CODE IN THE CR10 AND 21X PROMS IS
COPYRIGHTED SOFTWARE. A SOFTWARE
LICENSE AGREEMENT WITH CAMPBELL
SCIENTIFIC, INC. MUST BE COMPLETED
BEFORE BURNING ANY PROMS WHICH
INCLUDE THIS SOFTWARE. Contact CSI for
the cost of the software license.
The user specifies the filename. If no extension
is specified, GraphTerm adds the extension
.OBJ to the filename.
After the file is received, the datalogger is left in
the telecommunications command state.
GraphTerm will enter the Terminal Emulator
option.
3.2.7 M -- MONITOR INPUT LOCATIONS
The M option digitally monitors up to 33 of the
first 254 input locations, shows input location
assignments for up to three graphs, and allows
the user to see and change the status of the
datalogger's user flags and control ports.
Monitoring and graphics are described in
Section 3.3.
3.2.8 U -- COLLECT UNCOLLECTED DATA
The U option will collect all data stored in the
datalogger since the last retrieval of data;
(GraphTerm keeps track of where it leaves off
after each data collection). Data collected with
the U option is automatically appended to the
file StationFilename.DAT. That is, the data file
consists of the same name as the current
station file with a .DAT extension.
The data are stored in the .DAT file in the
format selected in the station file: comma
separated ASCII or binary (same as in the
datalogger).
3.2.9 E -- EDIT STATION PARAMETERS
The E option allows the user to edit the
parameters of the current station, or
establish/edit the parameters for another
station. See Section 3.1 for instructions on
setting up a station file. If an MD9 or RF
network is being accessed via telephone,
GraphTerm can be told to only hang up the
MD9 or RF portion of the existing link by
appending /9 or /R to the station name when
changing to the next station, allowing several
stations to be called with a single phone call.
3.2.10 V -- VIEW GRAPHICS FILE
The V option will display any file that has been
captured with the view save command in
graphics mode. The view save command
stores a "snapshot" of the graph screen to a
data file named V_STNFIL.OOO, where
STNFIL the station file name (or the first six
characters of it). Each time a new screen is
saved, the file extension is incremented.
When the V option is selected, GraphTerm will
prompt "Graphics screen file name:". A
directory of all screen files can be displayed by
entering a "*". After entering the filename of an
existing graphics file, the image will be
displayed. At this point, the Up Arrow and
Down Arrow keys will automatically display the
next and previous graphics file respectively.
That is, the Up Arrow automatically increments
the extension of the screen file and displays it,
while the Down Arrow will decrement the file
extension and display it.
Some versions of DOS support a graphical
“print screen”, allowing graphs to be printed.
See the “graphics” command in DOS Help.
3.2.11 Q -- QUIT
Quit GraphTerm by pressing Q. GraphTerm
leaves the COM Port and its interrupt
completely disabled. Subsequent programs
must reinitialize the Port before using it (e.g., if
the Port is used for a serial printer, the MODE
command must be issued before the DOS
PRINT command will address the COM Port).
