2. PREPARATION
2.1 INSTALLATION
When installing the DSP4, use the 1/4x20x1/3"
mounting bracket screw holes on both side
panels (Figure 1.2.1 Item 11). Velcro is also
used in many applications to mount and secure
the unit. In direct sunlight, a sun shield or visor
may be used to reduce glare.
2.2 HARDWARE CONNECTIONS WITH
SM192/SM716/CSM1
1.
Connect an external 1 Amp 12 VDC power
supply to the DSP4 "DC IN 12V" connector.
2.
Turn on the DSP4 power switch.
3.
Connect the DSP4 male 9 pin ("TO
DATALOGGER") connector cable to the
datalogger.
4.
Connect the DSP4 female 9 pin ("TO
PERIPHERALS") connector cable to the
SM192/SM716, CSM1, or PC via a modem
(e.g. SC32A, COM200).
2.3 SYSTEM POWER-UP
2.3.1 POWER-UP SELF TEST
When power is applied to the DSP4, it displays
the message "DSP4 DISPLAY" and automatically
tests its memory. If the DSP4 passes the self
test, it immediately attempts to establish
communications with the datalogger. If an error
is encountered during this memory test, the DSP4
displays one of the following messages to
indicate the defective memory area:
"PROM 0 ERROR"
"PROM 1 ERROR"
"RAM ERROR"
2.3.2 ESTABLISHING COMMUNICATIONS
WITH THE DATALOGGER
If a datalogger is not connected to the DSP4, or
if the datalogger is not on, the DSP4 will display
the message "DATALOGGER NOT READY."
Once a powered datalogger is connected or re-
connected, the DSP4 establishes
communications automatically. If
communication cannot be established because
the datalogger is servicing a peripheral (Storage
Module, CSM1, or printer), the DSP4 displays
the message "DATALOGGER BUSY." As soon
as the datalogger completes the peripheral
function the DSP4 automatically establishes
and maintains communication. If for some
reason the communication is broken with a
properly connected datalogger, the DSP4 will
automatically re-establish communication.
3. OPERATION
3.1 THE COMMAND MODE
When an operating datalogger is connected, the
DSP4 establishes communication and enters
the COMMAND mode. One of the seven
following modes can then be selected using the
CURSOR key to position the cursor at the
desired mode and the SELECT key to enter the
mode.
RUN
Display Datalogger Input
Locations with User Assigned
Labels created with the DSP4 or
transferred to the DSP4.
LOAD
Load Datalogger Program with
Labels from Storage Module or
CSM1 to DSP4's RAM memory
and simultaneously send the
program to the datalogger.
SAVE
Save the Datalogger Program
with the current labels to a
Storage Module or CSM1.
PROGRAM
Program Datalogger with the
Program Stored in the DSP4's
RAM Memory.
LABELS
Create/Edit Labels assigned to
the Datalogger Input Locations.
EXIT
Exit Telecommunications with the
Datalogger and enable the
datalogger keyboard.
PRINTER
Enable Printer Output and Set
Baud Rate.
3.2 DISPLAYING DATALOGGER INPUT
LOCATIONS (RUN MODE)
3.2.1 CHANGING THE INPUT LOCATIONS
DISPLAYED
Use the CURSOR key to position the cursor
under one of the four location numbers shown
on the display. Use the UP or DOWN key to
change the datalogger location displayed.
