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
(20K
ROM). Memory
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
files.
Files in the file area are called RAM files.
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.
1.2.1 Why use a FTU?
The Field Test Unit allows the programming
and
interrogation of the data
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
fiIe
or onto cassette.
•
Load the logger with new programs from a
RAM
file or
from cassette.
•
Transfer logger data and programs between the
FTU,
cassette, and a host computer.
