DSP4 HEADS UP DISPLAY
3
Momentarily pressing the UP or DOWN key
causes a single location change.
NOTE: If either key is pushed for longer
than 1/3 of a second, the locations scroll at
a rapid rate.
With the cursor under the colon in the first
quadrant, pressing the UP or DOWN keys
causes all four displayed locations to change by
one location.
With the cursor under the colon in the forth
quadrant, pressing the UP or DOWN key
changes all four displayed locations by four
locations (e.g., if locations 1, 2, 3, and 4 were
displayed, pressing UP would display 5, 6, 7,
and 8).
NOTE: If you try to view input locations with
higher numbers than allocated in the
datalogger *A Mode, E09 will be displayed
on the datalogger.
3.2.2 STORAGE MODULE OR CSM1
PREPARATION
When communication is established with the
datalogger and the RUN mode is selected, the
DSP4 prompts the operator to prepare the
media used for recording data.
Storage Modules
The Storage Module (SM192/SM716/CSM1)
must be connected to the peripheral 9 pin
connector.
The operator then presses the CURSOR key as
prompted to signal completion of data storage
media. The DSP4 then begins to display the
first 4 datalogger locations. Pressing the
SELECT key returns the DSP4 to the
COMMAND mode.
3.2.3 STORAGE MODULE DATA
The DSP4 retrieves datalogger Final Storage
data along with the regular updates of the
display data. The Final Storage data are
buffered by the DSP4 and sent to the Storage
Module or CSM1. Data are sent to the printer (if
enabled) in printable ASCII format. DSP4
PROMS with a date later than March 1, 1993,
have the delay for tape removed.
The DSP4 retrieves Final Storage data
regardless of the Instruction 96 or *4 options
selected in the datalogger. Because the DSP4
maintains continuous telecommunications with
the datalogger, the datalogger does not have
the opportunity to send data directly to the
Storage Module. Final Storage data sent to the
DSP4 also remains stored in the datalogger. If
a Storage Module, CSM1, or printer is not
connected to the DSP4, the data can be
retrieved from the datalogger when the DSP4 is
disconnected from the datalogger.
In summary, Final Storage data can be stored
on Storage Module, CSM1, or printer by
connecting these devices to the DSP4 or by
connecting these devices to the datalogger after
test completion when the DSP4 is disconnected
from the datalogger.
NOTE: A file mark may not be sent to a
Storage Module or CSM1 while using a
DSP4.
3.3 CONTROLLING DATALOGGER FLAGS
WITH THE DSP4
The datalogger user flags are alterable by
pressing the user flags keys on the DSP4 front
panel in the RUN mode. When a flag is high in
the datalogger, the LED associated with that
flag is on. When a flag is low in the datalogger,
the LED is off.
NOTE: While in the Monitor mode of
GraphTerm, user Flag 8 cannot be toggled
when the communications is via the DSP4
to the datalogger.
3.4 PROGRAMMING THE DATALOGGER
The datalogger can be programmed with its
keyboard display, an SM192/SM716/CSM1
Storage Module, a program previously loaded
into the DSP4, or over a remote
communications link such as phone modem
(Section 3.5) .
3.4.1 FROM THE KEYBOARD DISPLAY
(EXIT MODE)
To program the datalogger from its own
keyboard, select the EXIT command to enable
the datalogger keyboard. (If the datalogger was
simply disconnected from the DSP4, its
keyboard would not be enabled for up to two
