3.3.3
Timing considerations
When copying a file from a host computer (via the RS-232 communications
channel)
to a
RAM file in the FTU,
a
delay of two (2) seconds must be
provided by
the
host computer after sending each line before
the next line
of the fiIe is sent to the
FTU.
This delay must be increased to thirty (30)
seconds per line when the
FTU
is storing
the file
on a data cassette.
NOTE: The transfer to/from a host computer is terminated by the last line
containing the termination word END followed by a carriage return.
(i.e.“END” then press Return)

(UN)LOADING TO CASSETTE/RAM
Either program “PLOT” or program “LOAD” may be used to unload data
from a Data Logger.
“PLOT” contains all the features of “LOAD” but “PLOT” (un)loading is
slower and requires a larger amount of RAM (memory).
