FUNCTION
This library option adds additional *D mode
commands that allow datalogger programs to
be saved to and loaded from a cassette tape.
INSTRUCTIONS
Command Description
3 Save Program on Tape
4 Load Program from Tape
SAVING PROGRAM ON TAPE
Use Command 3 to save a program on tape.
Connect the RC35 Cassette Recorder to the
datalogger via the SC92A Cassette Write Only
Interface or the SC93A Cassette Read/Write
Interface. The SC93A has three plugs which
plug into the microphone, monitor, and DC-
INput jacks on the recorder. Enter *D Mode,
switch the recorder to RECORD, and key in 3A
to initiate the program dump. When the
recording is completed, "13:0000" is displayed.
Command 3 writes an ASCII listing of the
datalogger program to tape. The information
saved on tape is the same as the printer listing
(Command 1). The C20, with the format
switches in the "II, Decode" position, will read
the file. The PC201 will read the file if the
TAPE.COM program is run and the File Data
Format is specified as either Printable ASCII or
Comma Delineated ASCII.
LOADING PROGRAM FROM TAPE
Use Command 4 to load a program from tape to
the datalogger. Connect the RC35 Cassette
Recorder to the datalogger via the SC93A
Cassette Read/Write Interface. The recorder's
volume setting should be near mid-range.
Position the tape at the start of the recorded
program before plugging in the SC93A. Enter
*D Mode, press the play button, and key in 4A
to initiate the load.
When loading a program from tape, the
datalogger suspends all other tasks, including
updating the real-time clock. An "L" is displayed
when a block of data is detected on the tape. A
tape read error will be signaled by an "E". If
data is not read within 30 seconds, the
datalogger displays E97. If there are no
incorrectable errors (E98), the datalogger will
display "13:0000" after the tape read is
complete. The new program will be in memory
and running.
