DSP4 HEADS UP DISPLAY
4
minutes.) After completing the programming,
press the DSP4 SELECT key to call the
datalogger and restore the COMMAND menu.
3.4.2 FROM A STORAGE MODULE or CSM1
(LOAD MODE)
To program the datalogger from an SM192/
SM716/ CSM1 Storage Module, connect the
Storage Module to the 9 pin "TO PERIPHERALS"
connector and select the LOAD command. This
brings up the LOAD menu. Press the user flag
key that coincides with the number of the program
to 'load from' the Storage Module. The DSP4
downloads the selected program. When the
program is loaded, the DSP4 automatically
returns to the COMMAND menu.
If the program is loadable, but for some reason
the loading is not completed properly, the DSP4
displays the message "DATALOGGER
LOADING ERROR."
A program can be loadable, yet contain
programming errors which also produces the
same error message.
3.4.3 FROM AN EXISTING PROGRAM IN
THE DSP4 (PROGRAM MODE)
The DSP4 retains a datalogger program from a
Storage Module or CSM1. To program or
reprogram a datalogger after the DSP4 has
already read a program, select the PROGRAM
mode. If no program is resident, the DSP4 will
display the message "NO PROGRAM IN DSP4"
and return to the COMMAND mode.
3.5. FROM A REMOTE COMMUNICATIONS LINK
Campbell Scientific, Inc. provides a number of
different methods of telecommunications to the
datalogger. Each of these methods are
transparent to the user when interrogating the
datalogger for data or programming. These
methods include the SC32A RS232 Serial
Interface, the COM200 or COM100 phone
mode, the MD9 coaxial link, and the SRM-6A
hardwire modems.
NOTE: When using telecommunications
with the datalogger and DSP4, the
maximum baud rate is 1200 baud. Also,
when using the DOS version of PC208, the
station file for the PC must select DSP4
Display as the datalogger type. This can be
entered by using the “H’ key rather than the
space bar to scroll through the hidden
options.
3.6 SAVING A DATALOGGER PROGRAM (SAVE
MODE)
3.6.1 IN A STORAGE MODULE or CSM1
When the SAVE mode is selected on the DSP4,
the DSP4 prompts the user to see if the media
is ready for saving the program. This means
the SM192/SM716/CSM1 must be connected to
the peripheral port. In that same prompt, the
user can select "FLAG 1 through 8". Select the
flag that corresponds to the number under
which the program is to be stored in the Storage
Module (e.g. press flag 1 to store the program
in program storage area 1).
3.7 CREATING/EDITING INPUT LOCATION
LABELS
With telecommunications to the datalogger
established with the DSP4, the labels associated
with datalogger input locations can be created or
edited. The operator selects the LABELS mode on
the DSP4, and the DSP4 responds by showing the
label for the first location. The CURSOR UP, and
DOWN keys are then used to create or edit the
labels. The SELECT key will then enter the
current label displayed. Editing labels over a
remote communication link is described in Section
3.8.3.
3.8 COMMUNICATING VIA A MODEM
3.8.1 COMMUNICATING WITH THE
DATALOGGER
NOTE: Communications with the DSP4
and datalogger via a modem is limited to
1200 baud.
When the DSP4 is in the RUN or COMMAND
mode, it can be called by a modem connected
to its peripherals connector. When the DSP4 is
called via modem, the DSP4 displays the
message "MODEM ACCESS". The remote
operator uses the normal datalogger
telecommunications commands and the DSP4
