The purpose of this documentation is to describe the function and operation of the Model
Portable Data Logger. This document is aimed at the inexperienced user
who is unfamiliar with the Field Test Unit

UNIDATA’s
The Portable Data
tion and transfer of data from
Logger
and Field Test Unit act as a team for the collec-
remote,
unmanned locations. The data logger
is a battery operated data gathering unit, and the Field Test Unit is a portable dedicated computer with specialized software for communication with
the data logger.
1.1 PORTABLE DATA LOGGER
The Portable Data Logger (PDL) is a microprocessor based device
designed to have a battery lifetime of over 2 years. This allows the logger to
remain in the fields for long periods of time for the recording of data. The
data is recorded in CMOS
RAM
memory which is available in 8K to 64K
capacities. The logger provides analogue and digital inputs for data sampling, and internal logger programs and crystal clock for the recording of
data in the logger’s memory.
1.1.1 Memory structure
The memory of the logger is divided into 256 byte Blocks (e.g. a 24K logger
will have 96 blocks, and a 64k logger has 256 blocks). Hence, any particular
location in the logger’s memory can be referred to in two ways: either by its
absolute location in memory, or by its block and location within that block
(e.g. absolute location 0 is also block
0
location 0; absolute location 1023 is
block 3 location 255).
Block 0 is
used
to store the clock, pointers, counters, accumulators, channels and other information necessary to the running of the logger.
Block 1 is used to store Buffer Pointer information (BLK 1, LOC
0) and the Data Logger program (BLK 1, LOC 128)
Blocks 2 & 3 are reserved for the Data Logger Program.
Section 1. INTRODUCTION 1
Field Test Unit Software
Blocks 4 onwards (location 1024 to the end of memory) are
reserved for logger data storage. Bytes are logged
sequentially, without gaps, and the number of bytes
logged per log interval will depend on the PDL
program.
1.2 FIELD TEST UNIT
The Field Test Unit (FTU) is a battery powered, Intel 8085 based
microcomputer with resident Microsoft BASIC
capacities of 8K or 16K RAM are available for program and data storage.
RAM memory is divided between a text area and a file area. The text area
is used for loading and executing BASIC programs. The file area is used to
store Program and Data
Both the text area and the file area are retained when the FTU is switched
off, but these areas will be cleared if the batteries are removed.
files.
Files in the file area are called RAM files.

1.2.1 Why use a FTU?
The Field Test Unit allows the programming
loggers in the field. The FTU can be used to
•
Display and alter channels, accumulators, and memory
locations in the data logger.
• Unload the logger into a RAM
•
Load the logger with new programs from a
from cassette.
•
Transfer logger data and programs between the
cassette, and a host computer.

Note, however, that the number of Bytes free may differ from the above as
it depends on the size of the file area that has been set (the size of the file
area can be changed)
1.2.4 Running a Program
To run a program, use the BASIC command :
RUN"filnam"
where filnam is the name of the file you wish to run.
1.3 CASSETTE STORAGE
Cassettes may be used for long term storage of Programs and data. It is advisable to keep a copy of programs on cassette, as the contents of the file
area may sometimes be destroyed.

1.3.2 Saving a Program
To save a program on cassette, rewind the cassette to a blank section, then
put the cassette recorder into RECORD.
To save a program that is in the file area type :
CSAVE“filnam”
Where filnam is the file name you wish the program to be saved under. It is
usually good practice to save the program twice (on the same cassette), as a
protection against corruption on the tape.
To save a program that is in the file area, first load it into the text area by
using the LOAD command :
LOAD“filnam”
then save it on cassette as above.
1.3.3 Loading a Program
To load a program from cassette, rewind the cassette to the start of the

3. (UN)LOAD, PLOT & COPY
The Model
6302A
Software Support Package (Version
V#5.0
or later)
(Un)load/Plot/Copy allows information to be unloaded from a Data Logger
and printed or plotted on a printer/plotter (Canon X-710) attached to the
80
Field Test Unit (Canon X-07). In print mode, any standard
printer may be used when interfaced to the
FTU
via the ‘Centronics’ printer
column
interface or RS-232 communications interface.
In addition, program and data
files
may be transferred between cassette,
RAM, Data Logger and a host computer in various formats.
3.1
STANDARD FEATURES
The (Un)load/Plot/Copy package will:-
a)
unload a Data Logger and store the resulting data in a RAM file
(requires 24k) or a cassette file on a datacassette tape.
b)
load a logger program from a RAM file or a cassette file into a
Data Logger.
c)
print the contents of an unloaded Data Logger direct or from a
RAM file or a cassette file in a tabular (column) format (up to
8 channels/fields per print) onto a Canon X-710 printer/plotter,
a Centronics interfaced 80 column printer or a RS-232 interfaced 80 column printer.
d)
plot the contents of a Data Logger direct or from a RAM
cassette file
in
a four color multi-plot format (up to 8 chan-
file
or a
nels/fields per plot) onto a Canon X-710 printer/plotter.
e)
transfer unloaded information or logger programs between a host
computer and the
FTU
in ASCII format via an RS-232 com-
munication channel.(see Appendix A for message format).
f)
transfer unloaded information or logger programs between an
IBM-PC type system and the
FTU
in LOGGER message format. (using the IBM-PC utility program “PDLIO”). Print or
plot logger files direct from an IBM-PC type system (using the
PDLIO utility program).
NOTE: The IBM-PC utility program PDLIO is not part of the

3.2 COMMAND

operator commands (entered into the keyboard in response to the questions
listed below) may be saved in a RAM file or on cassette.
This feature saves the operator entering
or unload is performed. Instead, the operator simply enters in the command

pre-saved operator commands from that command file.
Many command files may be created and saved, allowing command files for
a variety of loading, unloading, printing or plotting operations.
