1.3 OVERVIEW
The DSP4 Heads Up Display is a
microprocessor-based peripheral that
automatically interrogates an active datalogger
to which it is connected. The DSP4 displays the
current values of the datalogger's input
locations and automatically sends any
datalogger Final Storage data to a Storage
Module (SM192/SM716/CSM1) or serial printer.
1.4 SUMMARY OF FEATURES
•
Displays any 4 of the first 254 datalogger
Input Storage Locations with a 9 character
alphanumeric label for the first 99 locations.
- Locations shown are changed with scroll
UP and DOWN keys.
•
Displays the datalogger real time clock as
input location 0.
•
Allows datalogger flags 1 through 8 to be
set via keys on the DSP4.
•
Reads datalogger programs and labels
from a Storage Module, CSM1, or with
direct connection to a PC using an SC32A
interface. Cassette tape is no longer
supported after January 1, 1998.
- Program retained in DSP4 for
reprogramming datalogger without
rereading from Storage Module or CSM1.
•
Programs datalogger with the program
stored in its RAM memory.
•
Stores datalogger programs and labels
on Storage Modules or CSM1.
•
Allows input location labels to be
developed and/or edited directly.
•
Buffers datalogger Final Storage data
and automatically writes it to Storage
Modules, CSM1, and printer.
•
Yields access to the datalogger when
called by a modem.
•
Protects memory during power loss when
connected to an operating datalogger.
